When mastering for streaming platforms, what is the significance of LUFS (Loudness Units Relative to Full Scale) and True Peak values?

When mastering for streaming platforms, LUFS (Loudness Units Relative to Full Scale) and True Peak values are significant because they determine how the streaming platform will handle the loudness of your track. Streaming platforms like Spotify, Apple Music, and YouTube use loudness normalization to ensure that all tracks play back at a similar perceived volume. LUFS is a standardized unit for measuring perceived loudness over time. It accounts for how humans perceive different frequencies, providing a more accurate representation of loudness than simple peak or RMS measuremen....
