Hi! I have a 102 bpm sample and would like to avoid trial & error when tuning the pitch of the sample in order to make it fit the project tempo, which is 124 bpm. Is there a way to calculate what tuning-settings I need to assign in order to make a one bar 102 bpm sample turn into a 124 bpm one bar sample? Hope I’m making myself clear.
Adding 1 semitone multiplies the tempo by 2^(1/12), 2 semitones by 2^(2/12), etc…
Substracting 1 semitone divides the tempo by 2^(1/12), 2 semitones by 2^(2/12), etc…
In your case you have to reverse that, I don’t know how , but it is doable empirically.
3,381245 semitones is pretty close!
Edit : I found this online calculator, same result!
I think that’s it, thanks for asking!
X (semitones) = 12 log (BPM A / BPM B) / log (2)
12 log (124/102) / log (2) = 3,3812516208 semitones
You can use software like melodyne, which is really great to work on this kind of samples.
But ja ! Nice question and nice response ^^
Great, thanks a lot!
Follow up question, according to the calculation above I should pitch the sample to -3 right? But does anyone know how the decimals in the calculation translates to the fine tune parameter?
Fine tune +63 corresponds to 1 semitone. So I’d try 63x0.38=24
Not sure if it’s linear…
Awesome! I’m out traveling but will try this the coming weekend. Thanks again!
