Curious about getting the recent version of audacity. I have 2.0.5 installed but it doesn't have several options that I'm assuming ffmpeg enables - like being able to slow the tempo down but not change pitch. I assume it is an incompatibility with ffmpeg,, though I'm not sure. I've looked at the bug list and bug # https://bugs.gentoo.org/show_bug.cgi?id=524242 seems to suggest it is being looked at, but I don't really understand what they're talking about there.
I do have some work arounds - I can fire up my virtual machine Windows XP (doesn't seem to work well in my Win  and use it there (uggg!) or use VLC which gives incremental slow downs (for learning tunes) but I'm really used to audacity's interface. I could possibly also figure out which previous version worked - looks like it goes back to version 2.0.0 in portage.
Just curious if anyone has 2.0.6 or 2.1 running with ffmpeg support. Thanks, JD |

| ok, thanks for clarifying that for me. Appreciate it. Guess I should have googled around a bit more. /jd |

BTW, I have audacity 2.0.5 installed and in the menu there's a "Change tempo" tool which does what you want.
I tried it and it's a bit ugly, maybe recompiling with USE="sbsms -soundtouch" gives better results, but I didn't try that.
mpv is another player that can do that (and I like it a lot more than vlc):
| Code: | | mpv -af=scaletempo foo.mp3 |
(without the option, the default behaviour is to keep the pitch when playing faster and to scale it when going slower)
The default bindings are "[" "]" for 10% speed decrease/increase and "{" "}" for half/double speed.
| Code: | | mplayer -af scaletempo=speed=tempo foo.mp3 |
does the same. |

Thanks again, I did recompile with soundtouch - not sure why it went away from the last versions I had. I can try your other options as well.
I could mark the thread as solved but perhaps it is more for discussion purposes? Is it ffmpeg holding up the 2.1 version (better noise reductions, etc. in that newer version). /jd |
