SetTempoPerc method

SetTempoPerc method

Remarks

Changes the sound to play at faster or slower speed than original, without affecting the sound pitch so voices won't result altered.

This method doesn't work with sounds with more than 2 channels (5.1 or 7.1) or if the EnableMixingFeatures property has been set to BOOL_FALSE.

After a successful call to this method, the duration of the song will change: the new duration, expressed in seconds, is notified through the SoundDurationChanged event.

Further details about songs mixing can be found inside the How to mix your songs section.
