True peak margin is the safety space between your loudest reconstructed peak and the delivery ceiling.
Broadcast and platform specs often define a maximum true peak level, not only sample peak. The margin is how far your final export sits below that limit.
A file that looks safe on a sample meter can exceed the ceiling after reconstruction, sample-rate conversion, or codec encoding.
Masters printed right up to the ceiling are more likely to create overs in downstream processing. A small dBTP margin gives the delivery chain room to change the waveform.
The stricter the spec, the more important it is to meter the final file instead of only the live plugin chain.
Set the limiter ceiling with true peak metering enabled, then measure the exported file from start to finish. Keep a note of integrated loudness and maximum dBTP.
Meter Core keeps true peak visible alongside loudness so broadcast margin does not become a last-minute guess.
