Bitrate how do i sdet a bitrate need to record at 320 kbps constant bit raate

Im being told i need to record in a 320 kbps constant bit rate cbr
how do i check this - i dont see it under preferences


check MP3 and CBR in Preferences > Recording
In Mixxx 2.2+ you should have those options.

ronso im using mizz 2.2.3 and I don’t see that option under preferences - recording


Do you have an mp3 encoder installed?
