2 Audio Files/Tracks, and need to loop 1 track simultanously

Hello there,

How are you all?

I am using Audacity 2.x on El Capitan and it was obtained using the .zip

I need help with mixing the following:
1x 3 hour audio file (.mp3) - refer to as Audio A
1x 3 second audio file (.mp3) - refer to as Audio B

I want to be able to mix these two audio files playing simultaneously whereby; The 3 hour audio file (Audio A) plays whilst having the the 3 second audio file (Audio B) is looped continuously until Audio A has finished playing.

I want to also be able to export this into an .mp3 file.

Appreciate any assistance!

Thanks guys,

Import both files into Audacity.
Apply the “Repeat” effect to the short track (http://manual.audacityteam.org/man/repeat.html).
Use the track “Gain” sliders to adjust the playback level as required. (http://manual.audacityteam.org/man/audio_tracks.html#gain)

Thanks. I’ll give that a try!

Hi Steve, how do I make it repeat infinitely (until the second track elapses) instead of specifying the number of repeats?

Hi, this didn’t seem to work.

I selected the file and applied the repeat effect for 3 times just as a test - but it didn’t seem to work. The audio file was a .w4a if that changes anything.


Assuming that the other track in not infinitely long, you won’t need to repeat it infinitely.
In the dialog for the Repeat effect, the total length is displayed for the number of repeats that you set.

The format of the file is not relevant. Audacity does not operate directly on the file. When a file is “imported” into Audacity, the audio data is copied from the file into the Audacity project. Audacity operates on the copied data (not the original file).

Why, what happened?
When you set the effect to repeat 3 times, how long did it say the new length would be?

Hi Steve,
Appreciate your assistance. Yes turns out I didn’t click the sound file properly (wasn’t sure it was selected).
