Frequently asked questions
Will I hear the difference?
For speech, 96–128k is usually indistinguishable. For music, keep 192k or higher.
Why didn't my file get smaller?
If the source is already at or below the target bitrate, there is nothing to remove.
Which formats does it output?
MP3 by default, M4A and OGG optionally.
