Sound-Effects Library Loudness Checker
Check a sound-effect file's peak normalization and integrated level for consistent library delivery (peak-normalized to −1 to −3 dBFS).
Unlike music or speech, sound-effects libraries are peak-normalized — usually to −1 to −3 dBFS — so the user controls level in their session and keeps every transient intact. This checker reports both true peak (the thing to standardize) and integrated loudness (for reference), so your library stays consistent.
