RecordedSound.PlaybackRateSet method

Previous pageReturn to chapter overviewNext page

Remarks

 

Changes both the sound tempo and pitch of the playback stream, as if an LP disc was played at wrong RPM rate. The use of this method will speed up the sound playback and voices will result altered; if you don't want to alter voices, use the RecordedSound.PlaybackTempoSet method. The current rate percentage can be obtained through the RecordedSound.PlaybackRateGet method. The current effective playback rate ratio, that may be also affected by the RecordedSounds.PlaybackTempoSet method, can be obtained through the RecordedSound.PlaybackRateRatioGet method.
