... and this time when I walked round the corner, I was surprised to see a funfair set up in a nearby open space.  As the night was completely windless I walked back home, grabbed my hat, the Lark A1 wireless mics, and my camera, and shot this quick video.  Not that exciting visually, but it shows how wireless mics can be used for location recording in stereo, and not just for voiceover stuff.  Some of the sounds were quite loud, so it's kind of relevant to Taperssection recording... maybe...  I can't hear any distortion or compression / limiting happening

Rode have just announced that they have released a wireless receiver designed for camera mounting with 3.5mm stereo output for the Wireless Micro transmitters, so now you can use them with most recording devices, not just those with USB audio input. And it's free to those ordering the Wireless Micro kit, AND to those like me who already bought one.  Otherwise, it costs $149 AU, presumably for those who want two of them or something.

See https://youtu.be/e_wvKf9CSJs?si=keKk6fW7GT_fP3t1 for details.

^ wow, that's really innovative and competitive of rode. I assume you are on your way to the website to claim your receiver?

It's on its way right now!  Hopefully it will be at my house when I return there on Saturday.

So, what did I get? Stay tuned, I will follow up with that story later, it's a tale worth telling all by itself.......

Did I miss the grand reveal?

I've now received and tested the Rode 3.5mm outputting receiver.  To repeat, they are giving this to original purchasers - eg me - and it is now part of the bundle if you haven't bought the Wireless Micro before.  So what you now get is the tiny receiver that plugs into your phone or anything that accepts USB-C mics, plus an extra receiver that you can connect to anything with a 3.5mm mic input, eg audio recorder or camera.  And that receiver will also connect via USB-C to a phone or PC. 

The receiver is very small and light.  You could just about put two side by side on a credit card.  It has a power button, a button to connect to the transmitters (once off pairing), and a button to choose high medium or low output.  It has one rather bright LED strip which shows very clearly what had been selected by colour, and by whether one end or the middle or both ends shine.  Clever.  When you plug it into a plug-in power 3.5mm socket, it turns on (and off if you power down the recorder) so you don't have to think about that.  Underneath it has a spring clip designed for attaching on top of cameras.  They supply a short USB-C lead and a short curly (bright red...) 3.5mm lead.

I tested it quickly by connecting it to my Zoom H2essential and clipping the mics either side of my baseball cap to give the binaural stereo effect that I have described before.  I put the rig on a table at one end of the house and then walked around the rest of the house making noises and stuff wearing the cap.  Then I walked out the front door to the street and recorded a couple of cars passing, plus a bird call which was unexpected in the evening darkness.  Then back into the house, recording as I did so a minor digestive sound...  Oops.  The house has four bedrooms plus study, single storey, and it takes about 25 seconds to walk the length of it.  I don't know the actual measurement but the system worked perfectly over that distance, right out to the street, no loss of connection at all.

The sound was, as always with this rig, excellent.  The stereo image is very clear and wide.  I'm 76 so my ability to hear system noise is kind of lacking but what I could hear was tiny details of the ambient sound, not seeming to be covered by anything.  The rumble of the hot air heating was, well, rumbly, no indication of lack of low frequencies. 

So now this neat little system can be connected to a 32 bit float recorder for worry-free and idiot proof recording, and if the mics are tucked inside the cap rather than out, and the recorder in your pocket, it's as low profile as just about anything.

Alternatively I could picture the H2e in front of a group of performers with the wireless mic system recording to it as well, providing spot mics without having to trail cables.  Then mix the resulting four channels of audio later for best balance. 

I hope to do a video review in a couple of days - but currently the required camera is at another location.

Sounds like everything just works as expected! This is a great offering from Rode.

Quick addendum - the wireless receiver can be connected to a phone via USB lead, and then the Rode app can configure it and the linked mics.  And one of the options is to dim the bright LED display.  Which I did at once.  But in the context of outdoor use on a very sunny day, having the option to increase the LED brightness again is good.

I just made some test recordings with the Rode Wireless Micro devices connected to an audio recorder, now that it's possible.  Because the H2essential can record two stereo channels at once (the front facing mics plus whatever is plugged into the 3.5mm input) I decided to give that a go.  I compared a recording of hifi music playback flipping between those two channels, and then left the H2e recording music playing in the house while going out to the street with the wireless mics beaming traffic noise back to the H2e.  It all worked pretty well, and could even be useful for an incredibly simple way of recording a main pair plus two spots when capturing acoustic music.  What the test does show is that the actual mic quality of the Rode Wireless Micro is surprisingly good.  Way more low end than the H2e mics, slightly lacking at the top, but a bit of eq fixes that.  Here is a link to the tests -

(and part of the test uses my recently uploaded recording of the live performance of the St Matthew Passion produced by Jonathan Miller 32 years ago!  As many years ago as we now have floating point bits...)

[And proof of how this method of recording binaural sound is very stealthy - https://youtu.be/Vm6SyI_2WdM - a 16 minute unedited recording of walking to the local takeaway, standing in the crowded space waiting, and walking home again.  Nobody noticed.  Hollyland Lark A1 was the kit.]

My latest effort with the Hollyland Lark A1 binaural rig - including some quite loud canned music in a circus tent (which I did not realise had been set up round the corner from my house!) - also the loud transients on balloons being popped by kids.
