I don't think that's right. What makes you think the FLAC file is 320 kbps?

That's probably due to "dither". See: https://manual.audacityteam.org/man/dither.html
You may want to temporarily disable dither (set it to "None") if you are only trimming the file.

You can check the format and bitrate of your 'before" and "after" files with MediaInfoOnline.

EXPORTED NOW X2 FILE SIZE AND LOWER BITRATE!?

File size is determined* by the bitrate and playing time. kbps is kilobits per second. There are 8 bits in a byte so you can divide by 8 to get file size in kilobytes per second.



* Embedded artwork or other metadata adds to the file size without affecting the audio bitrate.
