Audio input example? about beatdetektor HOT 2 OPEN

@h2o- sorry didn't catch this issue til now -- the time is just the time in seconds (floating point) for the current spectrum frame.

For the microphone you'd probably want to use the time since recording started (sample_time - start_time) and for an audio track you can use the current playback time for the given sample. If you move the time backwards just remember to call reset() first, and starting at 0 is not necessary.

There's no built-in track change detection but it will follow tempo changes -- though it follows more slowly when it's recently had a solid BPM match and tempo changes abruptly.

If you know you're going to want to reset detection (such as a playlist change event) just use the bd_med.reset() function to reset state and start again.

I have finished h2o'2 code from above and committed it to a new repository: https://github.com/rickhurkens/beatdetektor_from_audioIn

Thank you people for your code and examples. This has saved me a lot of work :)
