Mastering for music, film and TV involves different approaches due to the different needs and contexts of each medium. In music, the focus is on optimizing the track for playback on various audio systems, ensuring consistency, tonal balance and dynamic impact. For cinema, mastering needs to consider the playback environment in movie theaters, ensuring a wide dynamic range and clarity of dialogue, as well as integrating perfectly with sound effects and soundtrack. On TV, mastering must meet the broadcast standards required by the platforms, maintaining audio intelligibility and consistency across different devices and listening conditions, with strict control over volume levels and LUFS to avoid distortions and maintain sound quality. .
