AIFF and Wav are proprietary digital formats????? AFAIK every modern DAW saves its audio files to AIFF and WAV somewhere inside the project folder. Granted, this does not include MIDI tracks that have not been rendered, so if you don’t want to lose the sound of those tracks and any virtual instruments you are using, better render the MIDI tracks when finishing the project. The only downside to all of this is that raw multi-track files in a project don’t include any additional processing or edits (depending on DAW), but that’s what stems are for. It would be good practice to render every single track to equal-length WAV files when completing the final mix.
