Can only export part of project

I can Export from 2.1.3, but can only Save 36:23 from a 1:20:00 track. I’m using Sierra. Can anyone help?

Try exporting it in a more reasonable format, such as 16-bit, 44100 Hz.
To set the sample rate, select 44100 in the “project rate” box in the lower left corner of the main Audacity window.

Thanks, Steve, but I definitely want 192000 for this project.

The maximum size for a normal WAV file is 4 GB
so either you need to use a different format, or split the project into multiple files.

Great! I believe you’ve supplied the solution. I’ll try it. Thank you!
