Hello! With Spotiget’s MP3 converter, you can choose MP3, WAV, or FLAC. The audio still depends on the source matched to your public link. Choosing WAV won’t bring back detail that was already lost in that source. For a small listening preview of your published demo, MP3 is a reasonable fit; keep your original recording files for editing and any future master. I’d judge the preview on the headphones or speaker you normally use, then save the version that works for that purpose. Keeping the preview and your original session in clearly named folders will also make them easier to tell apart later.
