exporting multiple tracks at once

i know about the export multiple option which exports files based on lables, but can i do a similar things based on tracks?
so say i have four tracks in my project, and i want audacity to export four .wav files for each of the tracks.

I assume you mean one WAV for each of four tracks.

Try putting a label at the top of each track. File > Export Multiple.


Yes. Select the tick box: “Split files based on tracks”.
