Audio Normalizer
Analyse peak and RMS levels and normalise an audio file to a target dB with preview and WAV export.
Peak mode hits an exact sample peak (ideal for avoiding clipping); RMS mode matches average loudness (better for consistent perceived volume). Gain is capped so the result never exceeds -0.2 dBFS.
