Use speed/duration to have audio follow video.

That definitely works for clips with few and simple changes in speed, but what can I do about gradual changes? Slicing up an audio track into 10 parts to provide the illisuion of a gradual change in audio speed doesn't sound fun. There has to be an easier way.

In Premiere, there isn't. You may have to go to Soundboth or Audution for this.

Time remapping allows gradual speed changes in video, but audio does not follow. It would make a good feature request to have a check box, that allows the option, though.

I've never used Soundbooth and haven't the slightest idea on how to do this.

From what I understand, I need to copy the time remapping's keyframes from Premiere over to Soundbooth, so that I can achieve the same remapping with the audio as I did with the video. Except I don't know how.

That's where the Soundbooth Help file and forums come in handy. (Preferably in that order.)

Can't say as I see any real use of audio following video. Either the pitch goes down or up with it, or, I believe you can maintain pitch but the distortion and noise makes it useless imo. Minor speed changes may work but major change doesn't.

I can think of at least a dozen movies off hand that use time remapping, and they certainly didn't just dump the audio... If you're editing a video of someone talking and you slow it way down, why would you want their voice to continue at normal speed and get out of sync with their mouth? Whether or not the audio would need some tweaking at the end is besides the point, keeping it's duration and easing as close to the videos as possible would only make sense unless you had explicitely locked or unlinked the audio from the video.

Did anyone ever find an easy way to do this?

I Know it might be a bit late, but since google brought me here, I thought I would update this with how I do it.

To change the speed of a clip at various parts and have the sound change also, is a bit tricky but ill explain it.

first go into the time remapping panel and add the start and end keyframes for your part to speed up/slow down.

Then alt click the audio to select it ONLY. Use the razorblade tool to cut the audio at both parts where the keyframes are, you will see the lines on the clip to guide you.

Then time remap the keyframed section, alt click to select the audio only, and use rate stretch to make the audio match the length of the video. Voila.

I used that technique today and it works great and doesn't take too long.
