USB Audio Recorder PRO

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 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.
