# 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.

# will play track 1 with a pitch of 90%,
