FourTracks

FourTracks is a small tool with which you can record from your Android microphone to one track, while listening to one, two or three other separate tracks.

When you start using the four tracks together, you will see each of them on the left of the screen, very clearly presented with their own controls (red button for recording and yellow button for mute, along with the volume control). Below these are the forward and rewind controls, a button to start the playback or the recording, and a pause button.

The application allows you to load up any audio files that you have on your machine in a number of formats (.wav, .mp3, .ogg), and use them on the tracks in the main window. You also have the option to change the pitch and tempo of the tracks, as well as exporting and mixing all the tracks to a single WAV or OGG file in full CD quality.

FourTracks is a simple but very effective tool that fulfils its purpose perfectly and allows you to record or play any file with ease.
