I'm fine supporting something like this, but unless there is a third party library that makes it simple to convert audio input into BPM, it's going to be quite awhile before I would have the bandwidth to implement something like this. It sounds pretty complex in nature.

Thanks Mike:

    Here's a Java/Android library that might be helpful.  It fires on event "onPercussion" or on other Sound Threshold:

  It also includes provisions for pitch detection, so maybe and On Screen Tuner could be added too.  I'm a drummer, so that doesn't really matter to me, but someone else might be interested
