On an audio project I changed the length of music tracks to get
them fit into a time slot. I found that you can go to about 7%
difference from the original before it starts sounding obviously
wrong, if you were familiar with the original. Of course if you've
no experience of the sound at all then you can't say whether it's
faster or slower than it's meant to be. I doubt whether the effect
of a small drift of FRC will be noticeable
