Frequently asked questions
Will the Opus lose quality?
Opus uses lossy compression, so some fine detail is discarded to make the file smaller. At the default quality setting the difference is very hard to see. Raise the quality slider if you need the result to stay closer to the WAV original.
Will the Opus be smaller than the WAV?
Usually yes: a minute of audio takes about 10.6 MB as WAV and about 1.4 MB as Opus at 192 kbps. Lower the bitrate to shrink it further; 128 kbps is plenty for speech.
