How can I stretch audio?

[gte024h]

I am trying to encode a TV series DVD and I ripped all the episodes together. Unfortunately the WAV is about 1 second shorter than the video stream over about 2.5 hours. Anyone know of an easy way to stretch a 2.5 hour long WAV by about a second?

If I had time, I would have ripped each episode individually, but I didn't and I think if I can just stretch the WAV to match the video run time it will match up just fine.

You can do that with any audio editting software.
I can recomend you "Sony Sound Forge" or "Samplitude" or "Sequoia"... those are expensive programs, but you can try with "Nero Wave Editor" that comes together with Nero, I am sure it can handle big wave files too.
Greetings! :)

Yeah, I have Nero Wave Editor (the most recent version) and I can't find any "stretch" command. I'm no expert though, so maybe someone with more experience would know how to do it with Nero Wave Editor.

The other programs are a bit overkill for what I want to do... if I can find no easy way to stretch the audio, I might just divide the time difference by the number of episodes, then cut that amount of time from the video between each episode.

SoX can do this:

Look at the speed effect.


If you prefer a GUI, there's Audacity:

Look at the "Change Speed" effect.

Audacity is a good tool I've used in the past and it's free.
