How to edit mp3 files with Audacity

Audacity is a good free audio editor.  Note that it's a third-party program, and not something that we support.  Please see the Audacity help page if you need further assistance.

These tips are written for Audacity 1.3 beta.

Hold music > Exporting audio files to the correct .MP3 format (music)

1. Once you load up your audio file, in Audacity 1.3 beta, go to File -> Export.

3. Change "Save as type" to "MP3 Files". 

4. Click the "Options..." button. 

5. Change "Bit Rate Mode" to "Constant". 

6. Set "Quality" to "128 kbps".

Adjusting hold music volume

Under the "Effects" menu, look for "Amplify".  Negative values (such as -4db) will reduce the volume.

This is very un-supported - Fonality will not be able to assist in transcoding, editing, or adjusting your MP3 files, using the Audacity audio editor, nor troubleshoot any problems with editing the files.
