DubDub recorder

DubDub Recorder is a simple multitrack recording app designed for quick song ideas and demos. Record with a microphone, import audio from a movie in Camera Roll, and mix multiple takes into a final track. The free version supports up to two records.

Mixing features include listening to recordings, applying a reverb effect, saving the result as a movie, and exporting or sharing to other apps. You can also copy a record or a complete mix to create new versions.
