In  FS#8894  (the original timestrech task), an updated version of the algorithm was uploaded.

The author said it performs and sounds better, so we should try to incorporate it.

I've tried building it, but I can't get a useful result, but I'm also not sure if I used it correctly. I used ./scale 2 < in.wav > out.wav. The result wasn't streched, but had crackling noises every few seconds.
   scale.c (10.1 KiB)
This task depends upon

Did you have a good wav file? It worked fine for me. (gcc -O3)

Maybe my command was bad? I can try again, I can't remember anymore which .wav I used.

I used the same command you did. If you try it again make sure to use some O flag or it's unbearably slow.
