Topic: DPA d:VICE just announced

[BlindGuyEars]

Fixed mic returned from Gerr.
Also, got a pair of 4061's in the Yardsale for a good price.

Also picked up a couple of those mic mount (clips), SCM0017. They seem to be the best way to go for attaching to my shoulders etc.
The rig is coming together nicely, and I'll really be testing it near the end of May, for Slayer, with openers Anthrax, Lamb of God, Testament, and Behemoth. A real test of both the high SPL handling, and the battery life of my relatively new iPhone 8 Plus.

Question: The Shure Motiv app lets me capture in 24/48. Is there any reason to consider 24/96? I can barely hear 17K now, when I run experiments wiht a tone generator, so I'm not sold on the idea of capturing frequencies beyond roughly 20kHz.

I've seen some gear act more linearly, behave better, in the audible frequency range, when run at higher sampling rates. Any chance this might happen with the D:vice, or would I just be wasting bits and probably more battery life?

Congrats on the successful repair.

You'll get differing opinions with sample rate, from some who are more adamant about defending their position than others.  Personally I'm fine with 24/48.  For me the primary issue in making the choice is simply one of reducing the archival storage space burden. Of the couple of tests I made using my recording gear, made with classical acoustic music in an very good acoustic hall, I could not reliably detect an audible difference between 48 and 96kHz sampling rates.  That made my decision to stick with recording at 48kHz that much easier.  I understand the arguments about equipment linearity, Nyquist filtering, and all that.  The d:Vice is a newer generation than the Tascam DR2d I used for my personal confirmation listening tests, and presumably uses better quality filtering and converters.   Another argument which I have not tested personally is that some post-processing manipulations such as EQ may benefit from working with higher sample rate files.  If upsampling the 48kHz file after recording to do such work at a higher sample rate (some EQ's do this internally) is effectively equivalent or not with regards to that is yet another question.

The bottom line is that for me recording at 96kHz is simply not worth doubling the needed archival storage space.  It's mostly a practicality thing.   I'm also always recording 4 sometimes 6 or more channels, so that double size storage burden would be again doubled or tripled over the storage space needed for 2-channel.

i saw someone mentioned using an android tablet

can it be used with android phone (yes i realize you wont have access to the app)

if it does work as an audio device on android phone can you pop it on an iphone to use the app to make settings and do they "stick" when disconnected from the iphone?

I have successfully tested it on an Android tablet (Samsung Galaxy Tab S3) and phone (LG V30).  Obviously you need a device with USB C input/output to power the d:vice.  I used USB Audio Recorder Pro.  This was just a quick test to see that it worked, I have not tried setting volume levels.  Since the screen stays on, I am nervous that power usage will be high and an unhappy touch might shut the recording down, but these problems might be solvable.  I asked DPA support if there was any reason not to use Android or ways to for sure lock the volume settings on the d:vice, but got no answer.

I am VERY happy with the quality of 24/96 recordings I am getting with a dedicated iPhone 6S+.

DPA just reminded me that iOS gives precedence to the most recently-connected device. So, if your device doesn't have a headphone jack, and you must therefore monitor over bluetooth earbuds, Airpods etc. be sure to connect the D:Vice last, after the earbuds.

so phones with microusb are SOL?

and every usb C phone has what it takes to power +5V?

is the d:vice microusb, so you are using a male usb-c to male micro cable with the d:vice?
