[PD] Pitch envelope

[Ed Kelly]

So...

A sample has duration (x)

A breakpoint envelope has pitch transposition from -60 to +60 semitones.

How do I work out what that would mean for the duration - i.e. how do I make it 
so the whole pitch envelope happen within the duration of the sample?

I'm not a mathematician, and have been looking at integration, but I can't work 
it out. Can anybody help me?
