Could cmus increase/decrease playing speed without changing pitch?

[/ vt]

Hello all,

Yesterday it came to my mind that I would surely use such a feature. I am
not sure if it is already implemented as I use cmus from the official
debian 7 repo and the version is pretty old so I decided to ask the list.
And if it is not implemented already do you think that it's worth
implementing? In my case I use it to slow down my guitar practicing tracks
(for the curious , Frank Gambale Chop Builder). Currently I use Windows
(crap) media player to slow down the tracks avoiding the chipmunk effect.
And I only use my windows installation for guitar pro and media player. I
can replace guitar pro with tux guitar even though some features are
missing in tux guitar but I prefer it anyway since the guitar pro support
(I paid for this stupid thing) is awful and the answer is pretty much
"Sorry we don't support Linux, we support only Ubuntu!" (WTF!?). I guess
that I am already in their ban list as I really didn't receive any
responses to my last three or four support requests. Just don't buy this
software! I also found out that I can replace win media player with the
linux media player with `mplayer -af scaletempo` (but there is a catch -
you need mplayer with the scaletempo filter, luckily it works for me). So I
am definitely going back to my linux installation. I just decided to make
some noise and ask what do you think about it.

Hi,

cmus does not support that (as far as I know) and in my opinion it's not
a feature cmus should support, because it's a player and not an editor.
My suggestion: use an audio editor for such things. A certainly nice and
powerful open source solution is audacity[1], you might want to have a
look at that.

Cheers,
Johannes

Hi,

Yes I am aware of audacity and I use it for various stuff but it would be
more convenient to change this on the fly.
I am practicing something for example at 0.8 of its original speed and when
I find myself comfortable playing it I could increase to 0.9 and so on.
Otherwise I would have to create separate tracks for each speed for each
exercise/song or I'll just have to open them in audacity apply the filter
and play it from audacity itself. I understand that it is probably a job
for a library/editing software instead for a player but why shouldn't I
ask. Why can only win from such conversations ; )

Yes, there's nothing wrong with your request, that was just my point of
view ;-)
