Tempo Changes Don't Stick

Post by westfordjoe » Tue Jul 09, 2013 9:35 pm

I'm trying to change the tempo of various parts of a song that was imported from an AAC file. I highlighted each section separately, then selected Change Tempo from the Effects menu and changed the tempo. Then I saved the file. When I played the song, none of the tempo changes had stuck. I tried this several times and can't seem to get the tempo changes to save.

I'm using Audacity 2.0.3 on a new iMac running OS X 10.8.4.

Thanks!

Audacity does not "Save" audio files. The "Save" command (File menu > Save) saves an Audacity Project.
Apply the effect in Audacity.
Play the track to ensure that it sounds like you want it to,
then "Export" (File menu > Export) to create a new audio file. The new (exported) file will have the changes that you applied in the project.

Thanks for your reply. I was playing the track back from within Audacity, right after I changed the tempos is various parts of the track. This is when I noticed that the tempo changes I put in were not there any more.

I think I found a better way using the Slide Time Scale/Pitch Shift. It seems to introduce fewer defects and, so far, my tempo changes have stuck. Thanks for your help.

Also see the Change Tempo documentation in the Manual for an explanation of the limitations of Change Tempo:

Similar limitations apply to Change Pitch:
