4.9.6 Change Rate of Time-based Media

The user can adjust playback rate of prerecorded content such that all of the following are true (Level A):

- The playback rate of the recorded audio and/or video tracks should be user adjustable between 50% and 250% of real time.

- Recorded speech, whose playback rate has been adjusted by the user,
should maintain pitch in order to prevent degradation of the speech quality.

- Audio and video tracks are expected remain synchronized,across the playback range.

- The UA should provide a function that resets the playback rate to
normal (100%).
