Beets
A little iPhone utility that listens to music through the mic or Audiobus and displays its BPM.
BPM detection is implemented using the Aubio audio analysis library. Before building, you'll need to download the iOS framework from http://aubio.org/download and put aubio.framework into the Beets directory.
To build with Audiobus support, download the Audiobus SDK, place it inside the Beets folder as "Audiobus-SDK" and then build the "with Audiobus" target in Beets.xcodeproj. You'll get a parse error on AUDIOBUS_API_TOKEN_HERE, replace that with your Audibus app token and it should work.
