Mac port uses that:
http://developer.apple.com/Mac/library/documentation/QuickTime/Reference/QTKitFramework/Classes/QTMovie_Class/Reference/Reference.html#//apple_ref/c/data/QTMovieRateChangesPreservePitchAttribute

"
When the playback rate is not unity, audio must be resampled in order to play
at the new rate. The default resampling affects the pitch of the audio (for
example, playing at 2x speed raises the pitch by an octave, 1/2x lowers an
octave). If this property is set on the movie, an alternative algorithm is
used, which alters the speed without changing the pitch. Since this is more
computationally expensive, this property may be silently ignored on some slow
CPUs.
