Properly slowing down sound in FFMPEG?

[1xcalibur1]

Hi,

I used this tutorial to slow down some short clips:

https://trac.ffmpeg.org/wiki/How%20to%20speed%20up%20/%20slow%20down%20a%20video

But my problem is that the sound is WAY too metalic compared to how it's done everywhere else I'd seen before.

Take this for an example:

Any help appreciated,
thanks

ffmpegx is not ffmpeg. Moving you to our audio conversion section.

I guess you will get better quality with an audio editor like audacity, goldwave or the command line audio software sox.

Thanks for the reply.

would you happen to know if SOX is available for Android as well?
I only went with FFMPEG to begin with because it had plenty of implementation guides and a fairly simple CLI...

I doubt that.
