True Peak explained for Suno creators

Sample peak is the loudest digital sample. True Peak estimates peaks that appear between samples after conversion. Streaming and YouTube encode to lossy formats. Those extra peaks can clip even if your meter never hit 0 dBFS.

Why -1.0 dBTP

A ceiling around -1.0 dBTP leaves room for the encode. Going to -0.1 dBTP to “win loudness” is how a piano gets crunchy on a phone.

How to read the tool

Input True Peak is the Suno file. Output True Peak is after the limiter. If output True Peak is at the ceiling and LUFS is still low, the mix is too dynamic or too quiet in sections — do not keep slamming.

The workspace on helloseo24.com shows both LUFS and True Peak before you download.

FAQ

Is True Peak the same as LUFS?

No. LUFS is average loudness. True Peak is a peak safety number. You need both.
