How To Chop (as in chop and screw) Music

I’m new to audacity so please bear with me, I’ve been looking all around the internet and nothing has seemed to answer my question on how to chop music.


I started to play around with audacity and I believe I have figured it out.


  1. patience
  2. plenty of time
  3. practice

B). Instructions–

  1. Open the song of your choice

  2. Zoom in so that you can see the wave bars – probably until you can see multiple wave bars

  3. Select the short part of the song that you want to chop. (most people only chop a word which would be the equivalent of half a second)

  4. Go to effects, then select repeat.

  5. In the number type 1 (or however many times you desire)

  6. Now this part is tricky, you have to deselect the repeated part, go back to the beginning of the first part that you wanted to be repeated and cut away a very small portion of the audio before the word that you wanted to repeat (which that also might be half a second). Then select a starting point for playback. If you do not like the way that it sounds, undo the last thing and reselect a new portion of where you want it to be deleted. (Whoahhhh!! I know that might be confusing for you but thats the best way I can tell you at the moment. Hopefully I will be able to get some pictures up to show in a few days…)

  7. Once the song is to your satisfaction, use the speed effect to change the pitch and tempo together.
    If you’re like me, I like to change the tempo at one time then go back and change the pitch next. I never use the speed effect.

  8. Enjoy your work!! Maybe you can be a Michael “5000” Watts one day!!!

If YOU have questions, concerns, or would like to make a suggestion, please feel free to post

In Audacity 1.3, you can also use Ctrl+I to split tracks at the beats, then select beats by double clicking between the splits.
If you have two copies of the same track time shifted by one beat difference, you can then silence (Ctrl+L) the alternate beats of the two tracks to create chopping.

You can also use a “Time Track” (in the track menu) for the screw.

It would be so useful to have a user definable time line for doing this sort of thing so that you could display time in beats rather than just in seconds.
