Volume leveling (loudness normalization) adjusts a track so its perceived loudness hits a consistent target measured in LUFS, following the EBU R128 standard used by streaming platforms and broadcasters. It fixes the common problem of one song blasting while the next is barely audible.
DefyAudio offers it in two places: the Studio's Smart Volume Leveler normalizes a single track to a target you choose, and the Audio Joiner's 'Match volume levels' option normalizes every track before merging — perfect for a mixtape, podcast, or compilation where clips came from different sources.
Use the Studio's Smart Volume Leveler on each file, or in the Audio Joiner enable 'Match volume levels' to normalize every track before merging.
LUFS measures perceived loudness. −14 LUFS is the common streaming target (Spotify/Apple/YouTube); −16 suits podcasts. DefyAudio lets you pick.
No — normalization targets perceived loudness intelligently rather than a fixed gain, so quiet and loud tracks all land at a consistent level without clipping.
No — leveling runs in your browser, so your files stay private.
