Get yourself a stopwatch and find out how long a bar is then use the length to determine the BPM......it really is the best technique for determining tempos, cutting loops and stretching and it's not just because the values are all linked but because you are not messing with your only point of reference during editing.....that's the mistake people make by nudging loop markers around until they think it sounds right.......it's all quite unnecessary, if one bar is exactly 2 seconds long your tempo is 120 BPM and 1 bar of music at 120 BPM is exactly 2 seconds.....just like if a bar is 2.526 seconds long your tempo would be 95 BPM and vice versa.....it's all related.
Once you know how it only takes a couple of seconds to find tempo, cut a loop and stretch audio without skewing the timing off toward the back end.
In this example I determine how many seconds of audio there is in one bar of music with a tempo of 95 BPM.
60 seconds / (95 BPM /4 beats) = 2.526 seconds
To work out the tempo from the seconds......
60 seconds / 2.526 seconds x 4 beats = 95 BPM
Once you know the formula you will be way faster than you ever were without it.....seriously I can cut shit up on hardware faster than most cats can do with a mouse because I know exactly what I am doing before I even do it.
