AI Audio Enhancer

Model:
MP3, WAV, FLAC, AAC/M4A, OGG, Opus, WebM, WMA. Up to 100 MiB.
Speech-enhance preset: it rolls off rumble with a high-pass at 80 Hz, applies a light denoise, sits a narrow notch at 6 kHz to calm sibilance, lifts presence with a +2.5 dB peak at 3 kHz, then normalises loudness to -16 LUFS (a common podcast target). It works best on spoken word; reach for Mastering when the source is music.
~200 tokens per use

An ffmpeg speech-enhancement chain. It uses a different curve from Mastering because spoken word needs tighter dynamics and clarity rather than music-style glue.
