Loudness vs. Dynamics
Streaming platforms normalize the volume (e.g. Spotify -14 LUFS). More information: Itunes, YouTube, Spotify and co. – This is what your song should be like.
If you limit too much, you lose dynamics – and sounds worse than the competition.
🔹 Why does my track sound quieter after mastering?
Because streaming services LUFS vs. RMS evaluate differently!
Frequency balance in mastering
A EQ in mastering does not make any radical interventions, but serves the fine adjustment:
✅ Broadband EQ adjustments for a natural frequency balance.
✅ Corrections for different playback systems (Club sound vs. streaming).
Stereo image and spatiality
✔ Mid/Side techniquesto specifically adjust width or mono components.
✔ mono compatibility improve in masteringso that the track also sounds good on club systems.
Mastering for different formats and platforms
CD vs. Streaming vs. Vinyl
Not every platform has the same requirements:
CD: Can be mastered louder as there is no loudness normalization.
streaming: Pay attention to the level, otherwise your track will be turned down.
Vinyl: Special EQ adjustments required to avoid distortion.
Multi-platform strategy
A single master for all formats? Not ideal. Best practices:
Spotify & Apple Music and co.: Target: As loud as it sounds good. Check the conversion codecs (AAC, Opus, etc.)
Club Mastering: More punch, adapted to PA systems.
Vinyl master: Careful bass and dynamic control.
