SideBand was built for musicians to learn by ear.  Import music from your iTunes library or drag onto iTunes from your desktop.  Set loop points, slow the tune down to a manageable speed.  As a vocalist, find a better key to fit your voice.

The technical stuff

Import audio files in most of the major formats:

• MP3
• MP4 (AAC)
• ALAC
• WAV

Display metadata and add notes.

Accept files using AirDrop or from DropBox or Mail - actually, any app that can export audio.

Speed up to 200% or slow down to 50%.

Set loop points by tapping in and out. Adjust them with sliders.

Compensate for an out-of-tune recording by adjusting the fine tuning.

Reset tempo or tuning with a single tap.

Play audio in the background, so you can play along with a music notation app such as the Craic.
