covert the files to 192 bit rate

is there an image or video that shows how to covert the files to 192 bit rate :wink:

In what format? MP3?

If it’s for an audio book, you will probably want “192 kbps CBR MP3”, which you get by setting the MP3 Export options like this (below):
(See also: MP3 Export Options - Audacity Manual)

“192 kbps” is the bit-rate.
“CBR” means “Constant Bit-Rate” (usually required for audiobooks)
“MP3” is the file format.
