[CM] [SND] Files from (save-region) can't be read by other applications

[Kenneth Flak]

Hi, 

I'm testing this little piece of code to save all regions:

(let (
       (iterator 0)
       (filename "test"))
   (map (lambda (r) 
          (save-region r (format #f "test~A.wav" iterator))
          (set! iterator (+ iterator 1)))
        (regions))
   )

It works fine, but leads to the following when trying to play them back from mpv:

❯ mpv test*.wav
Playing: test0.wav

Failed to recognize file format.

Similarly, when importing into Reaper I get blank items. I can, however, open them in snd with no problem

I suppose I need to set the correct output format in the export sections, but I have zero idea which one I should pick for maximum compatibility...

Any help is most welcome!

Best,
Kenneth
