.wav converting for v3

I’ve really liked Notessimo v3, but the only issue is I can’t convert a song to .wav. Can you add that feature if possible?

That’s already a feature. If you’re on a song page you can click “Download WAV” on the New Player. If you’re in the composer, you can click on the Notessimo logo in the top-left corner and you should be able to download the WAV from there.
No offense, but did you even try to look for it? You can’t even listen to any song on the site without seeing the WAV button.

If you’re using V3, the best quality is .ogg
