BeuPeuMeu is a utility that converts a note length or a number of bars at a precise tempo, into samples number, and vice-versa.

Definitely useful to line up two loops with different tempos according to samples, or to determine the average tempo of a track...

Goodies: BeuPeuMeu also calculates delay time in milliseconds and in samples. Amazing, no?

BeuPeuMeu is a free freeware (believe it or not !), which makes it... pretty competitive, although it's in french.

Manual

Just click one of the red figures (values) to modify it, and the number of samples is automatically recalculated. If the number of samples is modified, the tempo is refreshed...

Once more, you just need to click on the values to modify it and recalculate the length (in milliseconds and in samples) of the delay.

Any Macintosh software using VST technology.
