EchoBox - record and play back

Use EchoBox to record audio practice and playback automatically, all hands-free. Tap the screen once to start listening, and EchoBox will record when it starts hearing sound. After a few seconds of silence, it will play it back, so you don't have to interact with your device to hear the recording.
Use EchoBox for practicing music, speeches, or language pronunciation. The sound threshold and silence duration are configurable.
