Pretty slick program, used it today on my wifes computer.
MusicMath, a free audio calculator
Laurent Colson releases MusicMath 2.21, now OSX compatible. Music Math is a freeware which converts music values (BPM, semi-tones, samples, ms, Hz, Timestretch %). You can calculate the time stretching to use on a sample if you change the tempo, or the number of semi-tone to transpose, the time stretching to apply if you transpose a sample and you don't want to change the duration, the delay in ms to synchronise with BPM. It also include a tap delay function and a BPM/sample converter.
Music-Math features 5 conversion functions:
- Tempo : computes the equivalent TimeStrecthing from the original and new tempos.
- Transpose: converts semi-tones to TimeStrecthing values
- Delay : convert tempo to musical duration (ms) or equivalent frequencies (Hz), ie for LFOs rates.
- Samples : convert samples duration (in samples) to tempo or tempo to sample duration.
