Video editor (Open source & free) that will time stretch audio

[Edward78]

I want a program that can edit speed of video & leave pitch alone...

I don't know whether it does what you want because I don't use a video editor. But Kdenlive is one to take a look at. Another would be Openshot. Both are open source.

Da Vinci Resolve might do it.
