N channels audio

Hi, i need to create mp3, ogg and wav file with more than 2 channels for testing some software which i programing… Thanks for suggestions

Audacity 1.3 can do this. Audacity 1.2 can not.

In Audacity 1.3
Go to “Edit menu > Preferences > Import/Export” and select “Use Custom Mix”.

When you “Export” (from the “File” menu) a project that has multiple tracks you will be given the option to map Audacity tracks to channels in the exported file.
