Pitch shift


I was wondering if there was a way I could slightly slow the playback speed to effectively shift the pitch of the music I play.

I would like to slow it down by 1.818 to bring music from 440hz to 432hz.

It would be AWESOME to be able to retune music.

there is a tool you can use : sox
It is included in Volumio
Have a look here http://linux.die.net/man/1/sox
And I think you would have to tweak mpd.conf to use it

Thanks there. any specific tips on how to achieve just that?
