- # Script to play audio tracks with different pitches
- # through a soundcard (cdda2wav must have soundcard
- # support enabled).
- #
- # Pitches are specified in percentage with 100% being
- # the original pitch, 50% being one octave lower, 200%
- # one octave higher.
- #
- # based on a script from Raul Sobon, who created the pitch
- # feature. Thanks Raul.
