I recorded a guitar sample using a seemingly in tune guitar, and the raw sample sounds in tune also. However, when I pitch shift the sample down by EXACTLY 400 cents (using FL Studios built-in pitch shifter) to get a sample that should be 4 semitones lower, the resulting sample sounds out-of-tune.
Can anyone explain why this happens, and if there are any better pitch shifting methods I could be using?
I've bounced a quick comparison of the original and pitch shifted sample playing one after the other, with an in-synth accompanying:
Any help is much appreciated!
