Can I speed up playback without changing the pitch?
Posted by Norman Willis on July 30, 2009 at 7:47 pmCan I speed up the rate at which the timeline plays, without changing the pitch? I’d just like to bump it up about 7%. Thanks.

Normally the audio will keep the pitch if you increase or decrease the pitch. But you can also adjust things to your need.
Just increase the speed of your audio event. Context (right) click on the audio event and select PROPERTIES.
In the tab AUDIO EVENT you will see CLASSIC selected for timestretch/pitch shift method.
For PITCH CHANGE you can select LOCK TO STRETCH if you do not want to keep the pitch. If you do want to keep the pitch, you can choose STRETCH ATTRIBUTESTheo

July 30, 2009 at 8:18 pmWhen you drag with Ctrl pressed from one side of the audio event to make it smaller (or larger), the video event will follow. If you change the lenth of the audio event in the PROPERTIES tab, the video event will not folow and you will have to adjust by hand.

Is there some special way to squeeze the event, and make it shorter, without raising the pitch?

Normally the pitch is NOT raising when you speed up the audio (squeeze the event, unlike an audio cassette tape that is speeded up). Unless you select the LOCK TO STRETCH option in the properties tab.

Would it also affect playback of a separate audio track (.mp3 musical accompaniment)?

Yes, if you group them first.
