USB Audio Recorder PRO

Record and playback audio in high quality from a USB audio interface featuring the app's custom USB audio driver! Bypasses the limits of the Android USB audio driver: no resampling, automatic gain or low resolution recording, but what enters your USB audio interface is directly stored as is. No root 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, it probably does not receive enough power. In that case you can try a powered USB hub in between.

Note that this app also functions as the license/key to use the custom USB audio driver inside our DAW, Audio Evolution Mobile Studio.
