Formulas for Audio Production

in App Tips and Tricks

I don't know about anyone else (a good starting disclaimer, right?), but over time I've had to work out formulas for various processes, particularly time related. I can't be the only one, so I propose a repository for these formulas. I'll start. I use these when trying to create audio loops:

Determine the BPM when you know the number of beats and the length of a clip (in seconds):

60 / (length/beats)

Determine the speed change% (in TwistedWave for example) when you know the current length in seconds and want to make it fit in a specific number of seconds:

(Old length / Newlength) * 100

Determine the speed change% (also TwistedWave) when you know the clips current BPM and want to change to a new BPM:

(New BPM / Old BPM) * 100

Determine the correct length (in seconds) when you know the number of beats and the BPM:

Number of beats * (60 / BPM)

anyone?
