Introduction
Handy Recorder is a high-performance PCM/AAC recording application that runs on
Android. Use it together with ZOOM Am7 stereo mic for Android devices (hereaf-
ter, Am7) for high-quality stereo recording. In addition, you can use this app to play
back and edit recorded les, to apply reverb and other effects to them and to share
them. This app can also start and stop recording automatically in response to the
input audio level.
