Key features
Eighteen formats, one quality knob
MP3, AAC, FLAC, Opus, Ogg, WAV, WMA and more, each with a single quality setting that means what it should for that format.
Keep each file's format
Change only the tags or the sound and leave every file in the format it came in.
Encoder options when you want them
Joint stereo, Opus frame size, FLAC search and the rest, folded away until you open them.
Tags that keep their meaning
Fields travel from FLAC to MP3 to M4A under the names your tag editor shows, with repeated values and totals intact.
Keep or strip, with exceptions
Delete every tag but a list, or keep every tag but a list, with wildcards and a separate switch for the cover.
A chain of effects
Trim, fade, level, clean up and reshape while converting, from a list you build once and reuse.
Even gaps between tracks
Cut each song where it ends and add exactly the silence you set, so an album plays as separated tracks anywhere.
One loudness for the album
Level to a loudness or a peak, or apply ReplayGain per track or per album, with a limiter against clipping.
ReplayGain tags
Write the levelling tags players use without touching the sound; they survive any tag cleaning.
Clean up old recordings
Take out clicks, rumble, hiss and harsh "s" sounds.
