How to speed up playback wo affecting the clip?
on Mar 15, 2017 at 11:22:42 am

I often use SV for listening and editing audio (I know there are better programs for this purpouse but for me it's more habitual to use SV) and I was wondering: is there a way to speed up or slow down audio playback? Not the whole clip stuff but only playback. I don't want to change audio, only want to speed it up or slow it down like you do in VLC for example. Is it possible?

Sorry, you appear to be contradicting yourself.

My Tivo has a feature that speeds up picture and audio by about 30% while keeping the audio close to the same pitch as normal. The purpose is to go through a program ( like an interview ) quicker.

Vegas can whip through a video track at very high rates. Scanning quickly though audio is more problematic.

What would you audio sound like at 10x normal? You could try applying on a track level, PITCH SHIFT .. Set the semitones to shift at 30 .. This goes about 10x normal speed. IT ran through a 3 min song in about 20 seconds. But the timeline cursor does not sync and stays at normal speed.

You can get up to 400% playback on audio by holding down the CTRL key and grabbing the end of the audio event and dragging it to the left. But, the timeline cursor does not keep up with this fully either.

This is something I never use .. but this will allow the timeline cursor to keep up at 4X rate. Combining this with setting the event to 400% playback will run through at about 10x or better ..

Hi Gennady

This is what I sometime use when I am in a bind or when I want to make the voice more anonymous. In your case, make sure that the Pitch shift is at No shift and he maintain timbre is selected. Then, just play with the Speed change, not to much or will start to sound funny. You can only use .WAV, .MP3 and .WMA files at 8 and 16 bits, not 24. Hey, it's a free software.....
