Demo: Time-Scaling and Pitch-Shifting
Select the name at the top of each box (such as "Female Voice") to hear the
original, unprocessed sound. Select one of the time-scaling
options (such as "1.2") to hear the
sound time-scaled by the selected ratio. Select one of the pitch-shifting
options (such as "0.8") to hear the original sound pitch-shifted by the selected
ratio. Note that the duration and pitch change independently of each other.
The scalings from 0.6 to 1.4 were computed with a time-domain technique
and the others with a frequency-domain algorithm.
