There are two versions for Mac. Videohelp only links to M1 and MacOS 11.X.
If you have macOS Catalina 10.15 or earlier versions you can find the other Mac version on it's official website freac dot org
great for extracting audio out of m4b audiobooks to prepare for m4b-tool to make a small 32kbps audiobook
great for converting 320kpbs mp3 to 96kpbs opus music |
