[MPA] Changing pitch: cents vs. percentage

[Joe Castleman]

I have obtained a concert recording which, I'm told, is 32 cents sharp.
My editing software (Audacity & Sound Studio) allows me to change pitch
in terms of a percentage, but not cents (which IIRC is hundredths of a
semitone).

Is there an easy way to calculate the change in percentage that would
equate to changing the pitch so it's 32 cents flat? Or could the
difference be attributed to variously encoding/decoding the audio at
48kHz or 44.1kHz somewhere in the lineage?

Thanks in advance,
