Im Support-Bereich macht Tidal in seinem Artikel »Upcoming Changes to Audio Formats« bekannt, dass sie den Schritt weg von proprietären Audioformaten hin zum Open-Source-Format FLAC planen.

For stereo sound, FLAC was chosen as the format we’ll support going forward because it is open source—meaning any artist can deliver their music in high quality directly to TIDAL without the involvement of a third party. This makes it easier for their fans to experience music in the highest possible sound quality on all their devices.
