Simple app to record audio from an external sound card and store it on the android file system.
The recording will be stored as .wav file on the external storage in a folder called "recordings".
In this free version of the app, the recording will stop when the file size reaches 50 MByte. If the app works fine for you and you would like the limit to be removed, check out the "USB Audio Field Recorder" app.
For a detailed description of the controls, please check out the "USB Audio Tester" app on the market.
