MP3, WAV.
Playlists recorded from different sources jump in loudness — one track whispers, the next blasts. Normalizing brings every file to a consistent target level so you never touch the volume knob mid-playlist. Run each file through the normalizer with the same target and they'll match.
Podcast platforms expect consistent loudness (typically around −16 LUFS for stereo). Normalize your episode before uploading and listeners won't be blown out by ads or straining to hear quiet passages. Pair it with the silence remover for gaps and the audio joiner to stitch segments — or let the AI jingle maker handle mixing and mastering of your intro automatically.
