To find the exact tempo of a loop when you know the sampling rate that was used to make the sample (assuming you are using the sample at its original pitch), set the start point and the loop point at the desired points, and subtract the start point’s value from the loop point’s to find the length of the sample. For example, assume a two-bar 4/4 loop = eight beats, sampled at 32kHz. The loop (according to the sampler) is 135,500 sample words: (8 x 32,000 x 60) / 135,500 = 113.35 bpm.
