As I mentioned in #22, have a look at demo_bpm_extract.py.

    bpm_periods = 60./np.diffs(beats)
    bpm_median = np.mean(bpm_peridods)

@xjefftang then asked in #22 (comment) Did you find that median(bpms) generally is more accurate than mean(bpms)?

Yes, very much so. The mean is very likely to give you a tempo period that is not in the original population of periods.
