i have been using a modified version of minim's beat-detection object for use within my own projects rather frequently, its in its own library (built in eclipse) for use with processing sketches.

i modified the source from minim so its not much my code as it is the author of minim,  i added the following function callbacks that deal with sound data i would  normally use:

void notifyBeatEvent(int bin, float instant, float E, float V, float diff)
void handleSpectrum( float[] spectrum );
void handleWaveform( float[] waveform );

the events are called from an event-notifier that distributes the messages of beat-events to objects extending an BeatEvent class, there are probably a few additional functions that would also be useful.


any suggestions? or thoughts / opinions, if anyone thinks its useful let me know (with all respect to the author of minim and thanks for the beat-detection)

----
sum: i think the reason i made it into its own library was because when i started using eclipse in my own learning of how things work - it just seemed easier to have a simple little object set for dealing with beats, although im definately interested in streamlining it for release is just my efforts to contribute to the community.

-thanks, if there is any interest i can post my revisions, just let me know.
