This question already has an answer here:

Is there any application like amazing slow downer for window or Mac?

Some of the features:

  • Change the speed of the music - from 20% (one fifth speed) to 200% (double speed) without changing the pitch.
  • Wrong key? Change the pitch in semi-tones - at full or changed speed.

  • Out of tune? Adjust the pitch in cents (100ths of a semi-tone) to suit your instrument.

  • Real-time processing - all described above is done in real-time - just insert the CD and press the play button!

  • Also slows down MP3, Wave, Windows Media Audio, Ogg, FLAC and AAC/M4A files on your computer in real-time. Note: M4P files from the iTunes store is now supported.

This question has been asked before and already has an answer. If those answers do not fully address your question, please ask a new question.

  • Not as detailed, but vlc does have slowdown/speedup options. – Karthik T Jan 31 '13 at 8:05

    So does smplayer. Evergreen: If that website goes down this question becomes hard to answer. It is generally a better idea to copy/paste some of the content of the website over and keep the link as a reference. – Rinzwind Jan 31 '13 at 8:40
  • Thank you Rinzwind for help making more clarification, I like it. Also thank you Karthik. I studied both VLC and smplayer, they help for a little speed change, but not specific and have no pitch change too. – evergreen Feb 2 '13 at 16:43

You could try Audacity (available in the software centre).




And about a million other things :)

There are ones with even more features available but Audacity is the simplest to use I think.

That program you talk about (Amazing Slow Downer) may run in WINE if you can't find anything else that meets your needs. It doesn't look like a very complicated application.


It look like I've found out the right thing. It's the app Play it slowly

enter image description here

Play it slowly is a light weight application but has a simple , clean interface. It is simple to use and has basic features such as:

Slow the speed on playback without altering pitch. Easily mark, move, and reset sections of a track for playback. Easy to start/stop/restart playback. Play is slowly is in the Debian and Ubuntu repositories

sudo apt-get install playitslowly
