PSR Calculator (Peak-to-Short-term Ratio)
Compute PSR — true peak minus short-term loudness — the moment-to-moment crush meter used to spot over-limited sections.
PLR describes the whole track; PSR describes right now. Drop your meter on the loudest chorus: if PSR dips under 7 dB there, that section is squashed even if the track's overall PLR looks healthy. The PSR concept comes from the Dynameter/loudness-war analysis community and maps directly onto perceived punch.
