Since it says DPA on it, it won't be cheap.

That being said...it looks pretty interesting. I think it will be pretty nice for shows with metal detectors. Maybe I'll get back on Team DPA with this thing.

Looks like Apple only. No Android that I could see.

Very cool!  This is a game changer.

Four channel version please..
..actually a six channel version is the thing of my dreams, but isn't likely.  Yet I can imagine them making a four channel version.

I don't care for the radially oriented inputs at all, which is simply terrible for cable management.  It would be much better if they were parallel with the USB port..  and arranged in two sets of three!

$650.

The built-in DAC is certainly a big value add, but that's really quite steep for what it is, IMO.

A single locking mini-xlr or binder input would be much better.. and will represent a considerable improvement in format on the forthcoming 4/6 channel version.  ;)  Since we're redesigning this for them, I'd like to see an on-board battery to increase run-time and reduce draw from the phone, with menu settings for power management with options like: draw from both sources; draw from internal battery first then switch to phone's power; phone-power only (so as not to burn phone-power charging a dead d:VICE battery); etc.

Curious how power-on/off, gain, filter and other settings work.  No obvious physical controls on the unit, so everything must be controllable through the app.

I think this is pretty awesome. If the battery life is as good as DPA says, it will be really great. I love how it can run both the miniature mics and the full size capsules (with the MMP-G cables). Form factor is a little weird, but not a deal breaker for me, as it will be a super compact set-up. I will almost certainly give one of these a try...

It's value is enabling a very compact, clean, direct-to-phone rig that fits in a pocket.  The disappointment is that the input format design doesn't provide robust input connector and cable protection - making for unnecessary strikes against compactness and pocket-ability.

I'd buy if DPA produces one that can do 4 or more channels, at which point it would need a single multi-pin mic input to achieve reasonable cable management.  Also would prefer it to work with Android devices.

I like simple and small

Some of my best recordings came from AT943ES / XLR mod.  >> FR-2

Will this polarize the AT943ES set properly?

Not having a 'droid app sux0rs, because mounting 128GB card is cake on all the new Samsung devices.

$650 to power the AT set, amplify as transparent or slightly warm the signal, and bucket to 128GB of phone storage would be all that I ever wanted from "taping", short of holding a CD in the air and having the show dynamically imprint itself in the dye.

Does the AT943ES function correctly powered with a 5 or 6V supply in 2-wire config?  If so I'd imagine they'd work, as I suspect that's the mic supply voltage this device provides.

Wouldn't full size capsules require phantom power thus a battery box in front of the DPA d:vice? I'm trying to limit the number of items and size for a stealth rig so this seems questionable to me.

I suspect the DPA "active" adapter cable thing with the capsule mount at one end and the microdot at the other contains voltage converter circuitry which steps up from 5V to whatever bias voltage the full size capsule needs to operate.. probably not to full specification as if using the DPA modular amplifier bodies, but "good enough for taper work" given the compact stealthiness trade-off.

Sounds like a much larger battery drain and thus less recording time. I totally agree with you on a mini xlr would be much more secure as well as robust connection over the micro dot.

Per DPA, the MMP-GR/GS cables were designed to allow the full-size capsules to work with wireless transmitters, many of which supply 5 V (they spec the cables at 5 V and 1 mA for full performance). As you suspect, the max SPL decreases, while the noise increases, so not full spec (compared to the MMP-ER/ES XLR cables), but still decent for many taper applications. No idea how this affects run-time, but DPA told me the MPS-6030 or MMA-6000 would work fine with them. Very curious about how they would perform with the d:vice.

Thanks for the confirmation on my speculation.  DPA has grown very modular over the past 5 years.  Lots of options here.

DPA mics are pre-polarised (ie: electrets) so they don't need a capsule bias voltage at all.

I should have referred to it as FET or transistor power I suppose.  Correct, no high-voltage polarization bias is required with pre-polarized electrets, so running the capsules off a lower supply voltage won't affect capsule polarization the way it does with an externally polarized capsule.  It's simply the power requirements of the buffer/amplification circuitry which needs to be met, and those requirements vary depending on the specifications of that circuitry, hence the 5V, 48V and 130V DPA variants. 

Most users are familiar with pre-polarized eletrets in the form miniature microphones, most often but not always with a non-balanced output.  Use of electrets throughout the entire high-quality, regular-sized, balanced-output capsule range is unique to DPA as far as I'm aware.  Historically when other manufacturer's have used pre-polarized capsules in their non-miniature lines, it's been restricted to their lower-quality microphone lines.  I've long thought about the implications of high quality DPA capsules being pre-polarized with regards to alternate non-phantom powering options, and this is the first I've seen of them leveraging that particular advantage.

Sort of off topic but I'm almost positive that I read that the AKG CK_X series is a pre polarized version of the original CK_ series of capsules.

The d:vice™ MMA-A comes with one Micro USB-B to iOS (Lightning) and one Micro USB-B to PC / Mac (USB-A) cable.

So it should be able to interface with a PC in addition to iPhones/iPads. Perhaps there will be Android connectivity in the future? I see two different images that appear to show the d:vice accepting both types of cables.

What happens when Apple inevitably changes the lightning connector to something else?

I would guess that DPA could address the (definitely inevitable) Lightning connector "upgrade" by offering a new micro USB-B to Apple cable?

I don't know that I would use this at festivals and the like, but for  >:D and live streaming it seems ideal.

But IF one wanted to use this at a festival, I wonder if this would be beneficial...

So it comes standard with a USB-B connector? It's difficult to tell from the pictures but the text seems to suggest that is the case. That certainly would be ideal.

I wonder if there would be a way to construct a breakout cable to allow for USB powering and 1/8" out.

Edit - it's showing up at B&H for $659.95, not yet in stock.

^ I think so, although it is difficult to tell. In the fourth picture down on this page, it does look like a micro USB. I guess DPA would avoid using an Apple connector on their side of things, too.

I just received an e-mail from Amptec (the Benelux DPA distributor) saying that these are shipping!  As they put it, "We were overwhelmed by demand since the initial announcement, so if you are interested in obtaining a unit, contact us ASAP." 

musicstore.de is listing them at € 569 and "Snel leverbaar, 5-7 werkdagen" (available quickly, 5 - 7 work days).  B&H has them listed at $ 659.95, but no availability as of yet...

I can't find any specs on what the gain range is?
Also is it possible to use other brand mics with this by using a adapter cable going from 1/8 mini terminated mics to microdot?

I expect it will work with other 2-wire low voltage mics.  I don't expect it would work with other phantom powered mics.

Seriously looking at this now.  The dpa app requires iOS 10.0 or better, which rules out really old iphones, but will run on an iPod Touch, which looks like a more affordable way to go for those with Android phones.  Can anyone point me to info on how the iphone/ipod would handle a digital-in signal, and how you would get the file out of it into a PC editor without going through iTunes?  Are there apps that record and open new files without loss when size limits are reached?

iOS treats digital and analogue signals the same if they are designated as 'mic in' and it records the file in whatever audio app you are using. No clever stuff needed.
AudioShare is a good cheap app for 2 channel audio recording - has a variety of input parameters that you can set, some post processing if you want (like normalisation), and lots of export options - via email, iMessage (Apple's text application) or WiFi server - it will advertise the phone and let you log on from another wifi connected device - the phone looks like a web page and you can copy the files.
I haven't done a lot of extended recording with it but it's never failed on 45 minute takes. I'd have to check if it will allow different levels for the two channels - I always record as a stereo pair.

Here's an unboxing video that was posted yesterday with audio from 4060 > MMA d:vice. They also connect a 4011 capsule to show the functionality.

Just finished checking this out. I am more impressed than I thought I would be...

Interesting note-the dpa app locks the settings in the d:vice, then you use another app to record (Eric was using hindenberg, which tops out at 2448, but there might be other recording apps that run 2496). I assume that you would pull the files off via the app window in iTunes (like you add flacs with the onkyo player), but that would be something specific to the recording app (and I have not checked out the Hindenburg page, yet)...

Want to mention that Eric could not have been more helpful. Good stuff!

The DPA specs say the d:vice supports sample rates 44.1 - 96kHz, but that the recorded sample rate is set by "3rd party app". Is that to suggest that the d:vice always sends a 96k signal?

Shouldn't this be a setting in the DPA app? What's to keep the 3rd party app from resampling if the user sets the rate below 96k?

It looked to me that the sample rate and word length are set by an external app... looks like the dpa app handles the analog side of things-set gain, apply bass roll off, and then the recording device takes over from there-setting rate and word length and then writing the actual file... The adc chip is the one in the iPhone, if my understanding is correct...

The d:vice is marketed as a preamp and A/D converter, according to DPA. That means the conversion to digital occurs in the d:vice, prior to the iPhone. Personally, I'd prefer DPA handle that portion of the stream. They wouldn't have sample rate specs listed if it were an analog device only.

I'd like some insight on what actually happens to that digital data once the iPhone gets ahold of it.

Haven't heard back, but when I look the d:vice up on the dpa site, I see this:

"44.1, 48 (default), 88.2, 96 kHz. Sample rates can be set by 3rd-party app"

So maybe the a/d is handled by the d:vice but not set in the dpa app, but via the recording app you use...

The A/D conversion is done by the d:vice. Apple's Lightning connector is digital only (unlike the old 30pin connector, which at one time was both analogue and digital, before it became digital only around the time of the iPhone 4S).

As well as the digital audio signal, Lightning carries power and control signals. So the DPA app can in theory set things like gain level and sample rate (it doesn't control sample rate at the moment). Other applications can also change these things, if the DPA d:vice and the 3rd party application use standard 'CoreAudio' functionality. The DPA app has a 'lock' button, which implies that the parameters it sets can be locked so that other applications can't change things. That would be a proprietary control.
It's hard to say how this will work in the real world without trying one.

As a similar example (and related, because Macs also use 'CoreAudio') - if you have an Apogee audio interface, the mic pre-amp gain can be set on the physical interface itself, and by the Apogee Maestro app on the Mac. If you have Apple's Logic (DAW) then you can alter the mic-preamp gain from inside Logic, but if you use Presonus Studio One, you can't.

Does that help? Probably not. We will have to wait to see..........

When I saw the demo, the dpa app locked the levels and the gain was not able to be altered with the third party app. However it was the third party app (hindenberg was the one used) that set the word length and sample rate. The app had only 2448 settings, but maybe garage band does 2496... I was told that the d:vice can go better than 24192....

If I hadn't just dropped a pile of cash on some other taping toys (mics, recorder), I would have ordered one already.  I will get one soon, though, after I replenish the coffers a bit.  A month or two.  I assume there will be many reviews by then; a DPA distributor I spoke with said there has been a LOT of interest...

Is the short MMA-A to USB cable that comes with the DPA d:vice the kind of cable you mean?

Do you know any Android recording apps that do 24/96 with seamless splits at 2 or 4 GB and keep on recording?

The Cables that come with the D:VICE are not suitable to run it on an android smartphone. Just for connecting with IPHONE or PC. I also tried using many adapters with these cables at first but none worked.
I finally got it to work with this cable: http://www.meenova.com/st/p/mbc_c2mu.html

I don't know about the recommandable recording apps myself yet. You can record 24 Bit/192 etc. with USB Audio Recorder Pro:
http://www.extreamsd.com/index.php/products/usb-audio-recorder-pro

It also splits the files at 2 GB.

Also i havent done a proper comparison to my non-stealth equipment.
I was just happy my stealth rig was reduced to nearly nothing when i got it to work yesterday :)
Quality (just recorded some music of my speakers) was excellent however.

That's encouraging.

The stated multichannel recording ability of USB Audio Recorder Pro got me wondering about running two d:VICE into one phone.
Found this similar inquiry, which is at least suggests that possibility in the future if not presently- http://www.extreamsd.com/forum/showthread.php?tid=442



Just thinking that option may come to fruition before/if DPA ever decides to produce a 4-channel version.

This cable will work with an android phone that uses a USB C cable, I have an ancient Samsung with only micro-USB (like the MMA-A itself).  What phone are you using?

The program does seem from the descriptions to do what I want (too bad there is no iOS version).

Good news and bad news on this.
I decided that although AudioShare and Recorder Pro would not let me record in 24/96, I would go with Voice Record 7 Pro, which did let me set 96kHz but shuts off recording at 4GB, I was attending a shortish accordion program and two hours would give me plenty of room.  It also turns out that people pull out their cell phones so regularly that resetting to start a new file will likely be no issue most of the time.  Now this was the first time I have taped accordion as well as my first run with the MMA-A so I was way low on levels (I do have sympathy for those who believe that you can never set levels low enough for accordion recording).  Good news is that even with a 12 dB boost the recording sounds fine, so at least two of the extra 8 bits are good. The MMA-A and app work very smoothly, and even after almost two hours the iPhone 6S Plus showed 93% battery left.
The bad news is that even though I got 24/96 size files, there was zero signal present above about 20kHz.  So the two other apps were telling me something true about the iPhone 6S Plus with the current iOS version, it doesn't seem to do 96kH (I know the problem is not with the MMA-A, since I can run it into my laptop and record with Audacity and those high frequencies are definitely present).
Does the Sony phone actually get real 24/96 recordings?  If so, with what app?  Anyone find an app for the iPhone which does 96kH with the MMA-A??

Just because you are recording at 96kHz doesn't mean there will actually be any information above 20kHz - just that it is capable of reproducing it if there is. Very few microphones will capture any data at that frequency range and very few things will make any sound at that frequency anyway. Violins, organs, maybe a few other instruments close miked will have very high frequency info but most will not. Also, it's above the range of human hearing capability, so I don't see what the big deal is.

This is very true. Cymbals and horns have a lot of uhf content too, btw.

Also if you're recording a PA system, typical dynamic stage mics used for rock don't have much over 20kHz, so the mix won't have much of that content either.

Uses I can think of for 96K include
improved anti-aliasing filters
making recordings designed for animals like birds or dogs
future-proofing your recordings in case humans develop improved hearing via medical, genetic, or evolutionary means
if you want to play back samples (for instance, of bird songs) shifted down several octaves and still wanted some high frequency content.

I found out a couple years ago that I can't even hear 13kHz anymore. I used to be able to hear television sets blasting their 15750 Hz NTSC lines, back when I half as old as I am now!!  :tomato:

The same mics (DPAs) into Audacity on a PC give signal up there very obvious in an iZotope Rx frequency plot of the file.  And, yes, you can't hear that extension if you select for it and have iZotope Rx play it.  But just like I like to have extra bits so I can boost a low recording level before dithering to 16 bits, when I get to work in iZotope I find it helps to have extra kHz for fixing junk like audience noise and background crap.  Can I prove that?  No. but I think others, who also can't hear above 20 kHz, like using 96kHz for that reason too.  Go tell SD, Nagra, and Sonosax to drop 96 kH recording.
I asked a question on Gearslutz about iOS apps for recording at 96kHz a few weeks ago, so far over 250 people have read it and the thread has logged not a single response.  Here people are more friendly, telling me several times that I don't really want to do 96kHz, which somehow doesn't really feel helpful.  YES I DO WANT 96kHz.  Even if I have to buy a Sony phone to do it (thanks for that pointer, Chrysler).
By the way, if you don't feel you need more than 48kHz and two channels, the DPA MMA-A is marvelous.

Not sure.  It may also be iOS 10.3, which my phone upgraded itself to last week.  A lot of the audio apps seem (by the feedback complaints) to have lost features in earlier iOS "upgrades."  The d:vice is new, so I haven't seen any reports of successful use at 96kH with other iPhone models or iOS versions.  I started out thinking the app was at fault, but I have tried three apps that claim to do 96kH and none can.

Early adopters blues. I was just wondering if this issue is due to hardware, operating system, or app

Color me confused, but isn't sampling rate the number of times per second samples are taken..? I didn't think it had anything to do with range of hearing...

That's correct.  Sample rate determines the frequency range capable of being captured - based on the fundamentals of sampling theory, frequencies up to half the sample rate are capable of being recorded and reproduced.  In reality slightly less than half is possible due to the impossibility of a infinitely sharp cut off filter, and in the real world all the other stuff involved - sources, microphones, reproduction gear, and all the other bits in between may or may not be capable of passing the high frequency information if it is there.

Nothing to do with what we can hear or not, but rather the "bandwidth" capability of the recording system.

^ The reason people are bringing up the range of hearing is that, beyond 40 kHz (plus a little for filtering, as implied by Gutbucket), you are recording frequencies that can't be heard.  By humans, anyway.  That's why CDs are 44.1 kHz; 20 kHz frequency  response, plus some room for the filters (some details from Wiki).

when I get to work in iZotope I find it helps to have extra kHz for fixing junk like audience noise and background crap.

Couldn't you just upsample with a good SRC for the editing?  I am pretty sure ~Jon Stoppable posted about doing that previously, but I can't find his post at the moment...

Not trying to tell you what to do or how to record. Just pointing out a few details that other users may be interested in.

John Peluso claims his microphones pick up frequencies up to 30 kHz and some folks swear that without the upper frequency data being represented the way we perceive the data (hear the sounds) in the audible range is affected. Like recording a violin, for example.

John Peluso claims his microphones pick up frequencies up to 30 kHz and some folks swear that without the upper frequency data being represented the way we perceive the data (hear the sounds) in the audible range is affected. Like recording a violin, for example.

Dan Lavry counters that argument in several of his venerable white papers, such as this one:

Quote from: Dan Lavry
It has been well documented that acoustic musical instruments generate energy at frequencies far above audibility. In the performance space (before any recording takes place), if there is any mechanism that enable ultrasonic frequencies to impact what we hear, it would require energy transfer from ultrasonic frequencies to the audible range. Therefore, using microphones and gear that cover what we hear enables us to capture and keep ALL the energy we need.

YMMV and all...

It should also work with an iPod with the appropriate connector, which may be cheaper (and have more memory).

Oh boy! Sample rate arguments.

Lavry' argument doesn't counter Peluso's so much as meshing with it in an pragmatic way.  In the paper linked above he states that he feels 96kHz is the preferred top rate for audio quality partly because it is capable of recording sources which reach up to ~40khz, yet isn't ridiculously wasteful of resources beyond that, where ever higher rates can actually begin to introduce problems of reduced accuracy.  He's a quintessential engineer by mindset, and engineering is all about finding optimized solutions to problems - the sweet spot in the middle ground, enough to provide leeway but not too much extra.

Working from that principle, I've reached the conclusion that for music recording in general, sample rates from 44.1khz to 96kHz are reasonable, and 192kHz (or more) is total overkill.  I choose to record at 48kHz because I couldn't hear a significant difference between 48kHz and 96kHz in test recordings I've made using my gear in optimal conditions and don't feel the doubling of storage space requirements is worth whatever subtle benefits the higher rate might provide, compounded by having found far more very-audible value in increasing channel count over increases in sample rate.  As my channel counts have increased, the need to keep file-sizes manageable has also grown increasingly compelling, solidifying that decision.  I'm always recording at least 4 channels, often 6, sometimes up to 8 or more. 

Those are my practical reasons for recording at 48kHz. I don't have any philosophical problems whatsoever with others choosing to record at 96kHz, but I do question the pragmatism of anything higher.

There is also a common argument about what quality envelope is really required to fully contain taper recordings of PA systems.  Okay, I understand that and it certainly applies in many cases here at TS.  Yet some members here such as WifiJeff are recording a lot of non-amplified acoustic music in fine acoustic spaces where the argument for a higher quality envelope gains traction.

^ Actually, Lavry argues that ~ 60 kHz would be ideal, but, since that is generally not an option, 88.2 or 96 are good (available) choices.  He definitely argues, in both this paper and his Sampling Theory one, that any audible impact of ultrasonics can be recorded with gear that captures the audible range; his reasons for going higher are purely engineering.

In any event, I am not arguing for or against 96 kHz.  Since WiFiJeff is having trouble finding software that works at 96 kHz, I was just suggesting a work-around that might meet his need for manipulation in post based on upsampling...

Atta Jedi!

Oh, how the tangents lead us astray.

I'm still trying to shed myself from the sheer want of this thing. It's not like I need it or anything. My bbox>m10 works just fine, but I find myself reading about this "device" more than I need to.

I'd rather find solutions to WiFiJeff's concerns, however, because this unit (coming from DPA) should operate as specified. This ain't Tascam! It's kind of annoying that they developed a control app to setup the d:vice, but then leave the user hanging on the recording end.

We've got plenty of fine threads debating the merits of higher sampling rates, and I enjoy reading them. I'm certainly not trying to stifle conversation here, fwiw.

24/44.1 or 24/48 seems to be optimal for humans using recorders.  Process in 32bit float, then convert to whatever you like.


Yeah, this d:VICE is a revolutionary step...let's get back on target with this thread.

Thanks for letting me clarify my opinion.

Sorry to interrupt these Hi-Res rants with some maybe useful info.

Following a suggestion from DPA, I purchased the Rode recording app.  I hadn't tried this because it has gotten some poor reviews and also didn't claim to work with non-Rode inputs.

I can confirm that it will work with the d:vice MMA-A and record at 24/96.  Signal  up to 40kHz (96kHz sampling rate) is definitely present.  I am testing now to see if it can roll over seamlessly at 2GB or 4GB.  Clearly Apple did something to break those other apps which think they can do 24/96, but iOS 10.3 and the iPhone 6s Plus are clearly capable of handling this resolution.  I hope the other apps get fixed since the Rode app is not entirely easy for me to use yet, maybe I'll get used to it.

Thank you for continuing to repeat these original and informative observations, which are not responsive to my inquiry and off topic to the subject of this thread.  I will forward them to Nagra, SD, Sonosax,Tascam, Sony and other manufacturers so they can adjust their future product offerings accordingly.  I am also coding a bot which will insert them into all TS threads that mention 96kHz recording (oh wait, maybe you've done that already).

The Rode recording app solves all my issues, though it requires some extra work.  You can select sampling rate and stereo or mono file before starting to record, when you finish and want to export you select the export format (.wav, mp3, FLAC, etc.).  For a shorter file I selected wav and got a true 96kHz wav file.  I then recorded for about three hours, it didn't do a split but for export there was no wav selection available, only CAF.  Audacity will allow you to load the large CAF file and split it to export as a 32 bit floating wav file, Wavelab and iZotope Rx can handle those.  The transfer to PC is either by WiFi or iTunes, WiFi can be rather slow but otherwise I've had no problems.

Hope to try it out in the field next week.

My bad.  I've gone back and corrected all the "kHs" to "kHzs" for all those who were understandably totally confused by my error.

Usually I tape piano using four channels, main pair of DPA 4081s (hypercardioid) with bass added from a pair of 4060s into a DR-2D.  So this omni-only run with the d:vice is for me not an optimal test, but the best opportunity for me until October.  I was close to the piano, but room acoustics not optimal.  I hope it gives some idea of what the DPA4060 > d:vice MMA-A > iPhone 6s can do at 24/96.

https://spaces.hightail.com/receive/An1XxGGZyF

The Rode Recorder has some quirks.  You have to load the DPA app before opening the recorder and keep it running in the background, or the Rode app will change levels I think, at least according to the readings on the DPA app.  And WiFi to my computer takes a while.  But I am reasonably happy with the results.  I started the recording well ahead of the start of the recital, it ran 3 hours and 20 minutes with the iPhone battery going from 100% to 80%,  so I figure I could record 15-16 hours with no other power source needed (will check out sometime what the drain is if using DPA4006 or 4011 with their active microdot cabling).  This is with wifi turned off and the screen allowed to go dark.

Opinions on the results for d:vice A/D and preamps welcomed (though I don't really care if you think it would be just as good at 44.1/16, see above and countless other threads).

The 4060s were in a croakie, I was seated near the tail of the piano front row.  The stage was raised, so I would estimate I was about 8 feet away out from the end of the piano and slightly below (maybe 1-2 feet) the top of the tail .  The room was not a concert room but had small tables in a boxy (but largish) room (but good views of the city). 

The Rode app has a settings page to choose sample rate and mono/stereo.  With the d:vice attached, you are offered up to 96kHz, but with just the iPhone mic you're offered only up to 48kHz.  As I said, when the recording is ended, you are offered formats for saving it, if it runs over 4GB it only offers CAF for uncompressed.  Shorter files can be saved as WAV.  I am avoiding touching the two ways to set levels in Rode Recording because it can, under some circumstances, change the d:vice levels.  My settings were low to be conservative until I get a better feel for the gear, and I boosted by 8dB in post.

Just did my inaugural run with the d:vice yesterday. Pretty easy to use, though I can't for the life of me figure out why DPA's own app doesn't just have a "record" function.

How did you get the Rode app to record from anything but a Rode IXY? That seemed to be the only thing it wanted plugged in when I tried it. I ended up using the Shure Motiv app that comes with the Share MV88. Worked great.

the d:vice does seem to be a power hog, though. In airplane mode it took my iPhone 7 from 50% battery to 5% in about 3 hours of use.

I got the iPhone 6S Plus for its bigger battery, but unless the % life it gives is skewed I can't imagine how the phone could run down that fast.  I do let the screen go dark so I have to key in the password  to reopen it, the recording goes on anyway and I found great battery life with 4060 mics, which mics are you using?  Could the Shure app be doing anything (mp3ing, processing) in the background to drain battery?  Or does it keep the screen lit?  One great advantage of the screen off etc is that you can't accidentally turn off or change anything while it's recording.

I set the d:vice levels with the DPA app and then just loaded in the Rode app, it ran fine.  You have to enable external mics in the app, but it doesn't seem toi insist on Rodes or any of the others listed as compatible.  You just have to buy the app, which I guess comes free with the Rode mics.  Can the Shure app be purchased without the hardware?

I agree that DPA should have included recording software in its app, should have been easy enough to do.

Shure motiv app is free but I wasn't aware it worked without a Shure motiv mic. :shrug:

i made a continuous 110 Minute Recording last week using the D:Vice and a Pair of DPA 4018 Capsules (with USB Audio Recorder using my Sony Xperia XZ Premium Smartphone).
I started recording with 90% battery capacity and when i was done the phone was down to just 80%.
I thought i didn't record at all, but it did. :O

How did the sound come out?  The 4018s are full size HyperCard caps, how do they sound on music?  I assume you were using the MMP-GR or GS cables.

The 4060s were in a croakie, I was seated near the tail of the piano front row.  The stage was raised, so I would estimate I was about 8 feet away out from the end of the piano and slightly below (maybe 1-2 feet) the top of the tail .  The room was not a concert room but had small tables in a boxy (but largish) room (but good views of the city). 

Jeff,

Very nice recording, and the Bach was very nicely played.  Sounds like you made yourself into a modified Decca Tail array!

What model piano is this?  It doesn't scream Steinway D to my ears, but that could be the room.


As to the d:vice - Yet another cool product that us Android people can't have!  I'm hoping that once all Android phones have moved over to USB-C that will change.

The Sony phone Chrysler is using is Android (but won't work on the Verizon network for me).  I asked DPA if this was doable without possible issues somewhere down the road, since they don't claim Android compatibility, but they haven't answered that one.

I believe the piano that night was a Yamaha, but they had Steinways for other events this month.

Anyone find a better price than the $560ish that Sweetwater is selling it for. 

Also has there been a consensus on what software is best?  I'm currently running DPA4061 > MMA6000 > M10 @ 24/48.  Looking to change that to 4061 > MMA-A > iphone/ipod touch. 

I hardly ever see any shows that run more than 2 hours so the 4GB limit really would never be an issue.  The auto/seemless split feature would be really nice since every once in a while it would come in handy.

not good (super bassy). i had them just hanging out of a bag that was standing right behind a huge PA.
this was primarily thought as test if i could just hit the record button and everything would go without me having to adjust anything (phone wont go out, battery will last sine my KORG-MR2 tends to switch itself off etc).

DPA just updated the app and d:vice firmware.  The main change is a way to sum both channels to mono (yawn) but also unspecified "bug fixes."

Been using his with the røde app @ 2496

Pretty cool stuff. Not sure what I would do if the levels were too hot, as it doesn't seem to let me change levels in the dpa app when I am recording. Also the meters in the dpa app are frozen when recording using the røde app, so it would be tough to adjust, anyway...

Has anyone else gotten a quick glitch when recording? I have gotten one each time I have used the setup. Don't know if my iPod is choking, if storage is scattered (no defraying an iPod), if I f'd it up checking things,  or what... barely noticeable, and a cross fade/pencil tool gets rid of it, but still...

Anyway, here is a sample result; would love to know what you folks think...

I have not noticed any glitches (with iPhone 6s), but I'll watch for them.

What battery life do you get with the iPod (and which model are you using)?

Battery life is terrific. Dim brightness, auto lock after 30 seconds and airplane mode...

I'm holding out for the 4-channel version.

Just posted this weekend on the DPA website, an excerpt from a Danish language review (I would love a translation of the full article) which notes:

"In this context, it is interesting that you can feed the d:viceTM a sync signal to one of the Microdot inputs and thereby use several d:viceTM units simultaneously and in perfect sync."  I would guess this requires two iPhones as well, but am waiting to hear from DPA on how this syncing would be done.

Reply from DPA, this doesn't look useful for me for four channel, unless with FOUR d:vices and phones:


"... we are using one of the audio inputs to feed the SMPTE timecode into the recording while leaving the other track free for a microphone input.
Tentacle has a small software (free) which erases the timecode track and leaves you with the file type you prefer and with the timecode embedded into the file.
It takes only a few seconds in the post situation to accomplish this.
Please visit the homepage of this timecode generator company:
https://www.tentaclesync.com/

The cable to be used for this purpose needs to be set up correctly and I can’t recommend to experience with other timecode generator brands without consulting the schematics of such types as we are sending out a DC (5V) on the MicroDot connectors.
Also we are using a “sense” mechanism to determine whether one or two inputs are active.

The set-up is very nice when you are doing work with multicam (on iOS) or mixed environment camera set-ups as the Tentacle units can be jam synced to other kind of gear (like an ENG camera, DSLR or whatever).


Other means of multicam recordings/productions can be made “on the fly” with for example the Filmic pro App and their corresponding Filmic Remote, where you can control several iOS units from a “master” iOS unit or even an Apple watch.
You can then make sure you are ending up with fx 3 files that have been started/stopped at the same time and with the same metadata.

For sound purposes only the Apogee App handles a similar recording."

On the other hand, I ran a quick and unexpected positive test of an Android bitbucket.  I just upgraded to a Samsung Galaxy Tab S3 with Android 7, and used the app which Chrysler suggested to me above, USB Audio Recorder Pro, which has just been upgraded to support Android 7.  A quick test showed recording at 24/96 successful, with all the high frequencies present in an iZotope scan.  So maybe the new Sony phone will work with the MMA-A?

Finally got to test my d:vice/iPhone with an orchestral group this weekend.  I am very happy with the result.  My impression is that it is cleaner than my earlier setups, DPA4060 > MMA6000 > D50 or DPA4060 > Church "Ugly" > M10.   Here is a link to a sample, comments welcome:

Having tried the d:vice MMA-A with piano, accordion, organ and period instrument group, I was anxious to try it also with symphony orchestra, to see if it would cover all the stuff I do.  So I hopped over to hear a local student orchestra with a young soloist.  I think it came out very well (and the waveform looks really clean).  Here's a sample:

That sound really nice, would you say that this thing could cope with stack humping at a heavy rock gig?

I have no idea, but I ran it with 11 dB gain using DPA 4060s, which are really hot mics, and boosted 1.7dB in post.  With DPA4061s, flat gain and no additions in post you have an additional ~23 dB of headroom over the loudest drum thumps of a Strauss suite (not in the sample I posted), from front row center in a smaller hall.  If that isn't enough room I'd hate to be present to try it.

Well, there's the Bach arrangement of "Lady of Spain."  I dunno, could be an interesting combo, ya think?
