Problems with exporting audio

Audacity Help Forum Windows
1

Hey,

I have a multitrack session with my song in audactiy. I want to export the track from the project, and move it to other program to add some additional effects. However, each time I am exporting the speed of the sound is different. For example I exported guitar track to 320kbs 40410 mp3 file, or wav file and each time I import it back to the project it is slower and no longer matches the rest of the tracks. How to solve this problem??

Thanks,
Piotr

Which version of Audacity? (Look in “Help menu > About Audacity”)

Which program?

How exactly are you doing that?

You mean the speed is different “in the other program”?

which project / which program are you importing it back into?

I"m pretty sure this is not an Audacity problem… Try simply exporting and re-importing to see if the speed changes. That should prove it’s not Audacity.

I’d like to blame the “other program” but I’d also be surprised if it is changing the speed accidently although we don’t know what program you’re using or what effects/changes you’re applying.

There may be something else going-on with your process. You’ll probably have to do some experiments to see where/when the speed-change is happening.

For example I exported guitar track to 320kbs 40410 mp3 file

Unrelated, but… What is ‘40410’ ? I assume you mean a sample rate of 44,100Hz (44.1kHz)?

And as you may know, MP3 is lossy compression. MP3 can often sound exactly like the uncompressed original but it’s “bad practice” to work in MP3 format. When you open an MP3 in Audacity (or any normal audio editor) it gets decompressed. If you re-export as MP3 you are going through another generation of lossy compression and the “damage” does accumulate. If you want MP3, compress ONCE as the last step.
