USB Audio Recorder PRO v1.4.0

Requirements: 3.1 + Modded Google Play

Overview: 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:

If you are more interested in a media player, please see our USB Audio Player PRO app:

eXtream Software Development has written custom USB audio code from scratch because Android does not support USB audio. 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.


• 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

• Display of available disk space

• Internal controls like gain, volume and mute are presented on the mixer screen if available

• 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! For a media player, see our USB Audio Player PRO app.

• Share your recordings through GMail, SoundCloud, etc.


• 800x480 screen minimum (in landscape)

• Android 3.1 or higher (no root required!!!)

• Android device with USB host capability

• USB OTG cable to go from micro-USB to full-sized USB if your Android device does not have a full-sized USB port

Just a glimpse of working audio devices:

• Lexicon Alpha, Lambda, Omega

• M-Audio Duo, Fast Track, Fast Track Pro

• Presonus 22VSL, 44VSL

• Blue Snowball, Yeti and Yeti PRO

• RME Babyface

• Zoom H2, H4

• Several HiFi DAC's

Unfortunately, Samsung S1, S2 and Note 1 devices are NOT supported because the kernel is missing some crucial parts. The S3, S4 and Note 2 work though.

Note that we are not affiliated with the USB Audio Recorder, USB Audio Field Recorder or USB Audio Tester app.


What's New

• Updated to the latest version of our USB audio driver code.

• A 'Failed to initialize' message could erroneously show if more than 1 USB device candidates were detected on the USB bus, even when the USB audio device was initialized. Solved.
