USB Audio Recorder PRO

About this app

Record and playback audio in high quality from a USB audio interface! Warning: this is not a generic driver, you can only playback and record from within this app. It is not possible to use your USB audio device with other apps!

Please have a look here for a list of tested devices and more information:

eXtream Software Development has written a custom USB audio driver from scratch because many Android devices do not support USB audio or not in the full quality that our driver offers. No rooting is required.

Your USB audio device must be class-compliant in order to work: USB 1.1 and USB 2.0 class-compliant devices are supported with either USB audio spec 1.0 or 2.0. Devices that require you to install specific drivers under Windows or OSX will usually not work.

Make sure to connect your audio device BEFORE starting the app. If you get a message on start-up saying that the device failed to initialize, your device will not work (for now). Reasons can be that your Android device does not meet the requirements, it does not supply enough power (try a powered hub), the USB audio device is not class-compliant or you are not using an OTG cable (if needed).

Please let us know if your Android/audio device combination works.

Note that this app also functions as the license/key to use USB audio in Audio Evolution Mobile.

Features:
• USB audio recording
• USB audio playback
• Mono, stereo and multichannel recording
• Stereo playback (on multichannel device, the first two outputs are used)
• 16-, 24- and/or 32-bit depending on your device
• Up to 384 kHz sample rate (depending on your audio device)
• Input/output selection
• Buffer size selection (1024 to 16384 frames)
• Recording format selection: wav/flac/ogg/aiff. (No mp3 since that is patented, use ogg for similar quality and compression)
• Level meters for playback and recording with peak hold to see what your loudest peak was (tap on level meter to clear)
• Monitor button to set your levels before recording
• Load wav/aiff/flac/ogg files for playback
• Rename or delete recording

• Set the folder you wish to record to, for example, external sd cards
• Play through your Android device's internal speakers or headset in case you have an input-only device like an USB mic
• Very basic playlist (directory playback) functionality because of many user requests. No mp3 playback or fancy graphics, the app is meant for recording!

Ratings and reviews

Works perfectly with my Behringer X Air XR18 and Google Pixel 2. I wish I knew about this way sooner...It would have made recording live shows a breeze compared to setting up someone's expensive laptop. I really wish that it recorded in mono instead of stereo but realize that might work the Android system harder. It's not a big deal separating the tracks in reaper. Being able to record 8 stereo tracks into an old phone is pretty remarkable. Not enough people in the music scene know about this...

This app works good, and the Audio sounds GREAT! 👍 I am using a Zoom U-24, and it sounds great! I cannot complain. I have one problem withf it, though: I haven't been able to use my SD card to save my audio. I'm not complaining, but this is the truth. Could you please fix it? It's a very important feature for me. Thank you!

This, and Audio Evolution Mobile are hands down the best apps for recording on Android. This is great for quick capture of ideas. A few changes to this app I would like: MUCH larger transport buttons. More options to customize the file naming format. For example: "Year_MonthDay_##". Also MP3 files. Now that the copyright has expired, more integration of that format makes sense for both apps. Regardless of any such changes, I'll be using this app for a long time to come.
