With Audio Looper+ you are able to mark certain positions in an audio track and loop between markers.
Available for iPhone and iPad.
Import audio tracks from your iTunes/Music library or directly from your iPhone/iPad.
Set unlimited number of markers for each track. The markers are automatically saved and loaded the next time you open the track.
The loop mode allows you to loop the playback between two markers.
The two waveform views make it easy to navigate within the track and jump to a specific position or a marker.
