Hello, about beatdetektor HOT 1 OPEN

@dominiroc11 just need to pass the un-altered FFT (it should look symmetrical) to beatdetektor with a timestamp -- bd.process(timestamp, fft_data);

After each update it will set bd.win_bpm_int and bd.win_bmp_int_lo if detection was reasonable. win_bpm_int is BPM accurate to 1 decimal place (but you have to divide by 10) and will take longer to detect and is usually inaccurate unless win_bmp_int_lo (which is just integer BPM) is also set.

If you're just processing a WAV file just tally all the win_bmp_int_lo values and pick the one that appears most. Once you find that you can compare to the win_bmp_int tally and find the best match that's < 1.0 away from the win_bmp_int_lo pick.

Also bd.beat_counter, bd.half_counter and bd.quater_counter will contain the current 1, 1/2 and 1/4 beat counts (which you can use as a counter to sync something to for real-time visuals) but won't necessarily contain the actual beat count from a track.
