A retention-first mastering chain for piano and lullaby channels

Generic AI mastering optimises for loud. Piano channels should optimise for minutes watched. The chain is short: clean export, honest measurement, a quiet preset, a WAV archive, then the platform encode.

The chain

1. Export WAV from Suno.
2. Measure input LUFS and True Peak.
3. Piano / Lullaby preset, about -16 LUFS.
4. A/B at the same volume.
5. Download 24-bit WAV.
6. Upload that WAV into the video, not a third MP3 generation.

What not to copy from pop mastering

Do not chase -9 LUFS. Do not clip the ceiling to 0. Do not add width until the piano doubles. Those tricks help a 15-second hook and hurt an overnight loop.

This is the difference in Suno Audio Lab: the loud presets exist, but the piano preset is the product.

FAQ

How do I know the master worked?

Watch retention on the next 10 uploads, not the waveform. If people stay, the loudness is right.
