Sound Editor is the ultimate music editing tool for the iPhone and iPad. This app allows you to import tracks and record your own, as well as use powerful audio effects. With multiple tracks, you can add different instruments to one audio track and edit them at the same time. Add different levels and effects to each of the tracks and apply them to each track individually.

In addition to editing tracks, you can trim, copy and paste the desired part of the audio file, as well as delete parts. There are several different types of audio effects that you can apply, including Fade In/Out and Silence.
