USB Audio Recorder PRO

Record and playback audio in high quality from most USB class-compliant devices.

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 OS X 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, or the 3 top-right combo boxes are not filled in, 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).

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.

By all means try the TRIAL version first to see if your device works.

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

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

• 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 the many user requests. No mp3 playback or fancy graphics, the app is meant for recording. Screen must stay on and the app must run in the foreground.
• Share your recording through GMail, SoundCloud, etc.

Requirements:

• 800x480 screen minimum (in landscape).
• Android 3.1 or higher (no root required...).
• Android device with USB host capability.

Just a glimpse of working audio devices:

• Lexicon Lambda, Omega.
• M-Audio Duo, Fast Track, Fast Track Pro.
• Presonus 22VSL.
• 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 and Note 2 work though.

This app does NOT allow you to output audio from other apps through a USB audio device. Neither is it meant to function as a generic music player. The playback functionality is primarily there to play your recorded audio.
