Split Mp3 file into multiple 20 minutes subfiles

Post by Super2020 » Wed Jun 16, 2021 8:28 am

Hello,

I'm new to Audacity and to Macro. I used the search first but could not locate what I'm looking for:

I import MP3 podcast (usually 2-3h files) and I'd like to split the file into 20 minutes files, for example if the source is 2h20min it would output 7 files in MP3.
At the moment, I do that manually by selecting start and end in the main track, copy paste in a new track and export that new track as a file. That's quite manual and time consuming.

Any idea how could I do that ?

I would place a label every 20 minutes and then use File > Export > Export Multiple
See: https://manual.audacityteam.org/man/spl ... racks.html

You can either place the labels manually - place the cursor and press Ctrl+B or automatically with Tools > Regular Interval Labels
See: https://manual.audacityteam.org/man/reg ... abels.html
