Spotify vs YouTube loudness for Suno songs

Spotify and YouTube both live near -14 LUFS in practice, but they are not the same encode and not the same listener. Make one 24-bit WAV, then let each platform encode it. Do not upload an MP3 that was already limited twice.

Spotify

Loudness normalization is on for most users. A smashed -9 LUFS Suno export will be turned down and can sound thinner than a -14 LUFS master with punch left.

YouTube

Context is a video next to speech, effects, and ads. A slightly more present master can help, but True Peak still needs headroom for the video encode.

One file, two presets

Render YouTube / Shorts and Spotify separately only if the song changes role. For the same release, one -14 LUFS / -1.0 dBTP WAV is enough. Use Suno Audio Lab and keep the WAV as the archive.

FAQ

Should I upload WAV to Spotify via a distributor?

Yes when you can. Give the distributor the mastered WAV, not a YouTube-loud MP3.
