USB Audio Recorder PRO

Previously I had this app and tried to use it with my pixel 6 pro.... I now have a pixel 7 pro and IT WORKS, I can connect this to a RANE MP2015 and select the 9-10 audio tracks through USB and record my DJ Mixes in flawless quality!

I am using this with a Rode wireless Go II and a homophone F1, and it works really well. The Rode transmitters keep a local recording all the time, and I have compared this to the wav files recorded by the app, and they are identical quality and volume. It is a great boon to have identical local recordings which can be dropped into the stereo mix without any processing being required at all when one of the transmitters have glitched on a vocal - which they are prone to if line of sight is blocked by a passer-by or clumsy assistant. The interface is a triumph of function over form. Very easy to use and very clear to check something is being recorded - it is not beautiful true, but it is instinctively useable and robust. The meters are to a scale I don't quite follow - quite loud recordings at 18 db continual peak show as very quiet according to the scale bars - this isn't a complaint It's nice to check there is input, maybe you can configure the scale, but I haven't found it. If your usb interface doesn't have a battery facility and needs the usb to draw power you are going to need a suitable OTG cable which allows power to be injected from an usb powerbank. These can be identified because they have three connectors, one for the phone, one for the audio interface and one to plug into the powerbank usb. This is discussed on the developers' website. Not having the correct cable is going to degrade your user experience, so you need to be careful about the quality and correct configuration of this cable. This is a pro quality app which does a great job in adding a convenient field recording function to an usb interface for the price of gin and tonic. With the Rode wireless Go ii I have a two channel wireless field recorder of exceptional quality that can be slipped into a pocket.

Really having a hard time with this software. I'm not going to rate it until I hear from the developers to see if there is a workaround or to learn definitively that the software simply won't function as intended by me. (Ugh, I can't submit without a rating, so I'll give it a 2 for the moment.) I'm using a Galaxy S21 and a USB-C to 3.5 mm dongle to connect with my microphones - condenser, shotgun, binaural, and a couple of tiny weeny things. I can't get any input whatsoever into the recorder! I do get an 'initialized' notification, but when I try to record it says 'no input channel.' Is this software only meant to be used with a preamp? I wanted to use my phone as a simple field recorder without taking along any other accessories, which is what I thought I could do with it. Anyhow, before you ask, YES, I can record into other audio software with the same setup, so there is definitely some incompatibility of some sort going on here.

Overally works. However, you should've mentioned that there is no way to record multi-mono inputs, as all inputs are summed to stereo inputs when recording multichannel IO. Also, the limit for file writing is about 4.8 GB, which I'm not sure is an Android restriction or not, but limits multichannel recording to about 35 minutes per file.

I couldn't get it to work with the pixel 6 pro. I wanted to record channels 9 & 10 from my Rane mp2015 digital mixer :-(

Couldn't make it work with other Audio recording Apps such as Band lab, open camera, etc...
