A couple more:

    afconvert(1) - an audio file format converter, which includes Apple's superior AAC codec from the Core Audio framework

    diskutil(8) - tons of tools for fixed and removable storage
Examples:

    afconvert in.wav -o out.m4a -q 127 -s 2 -b 160000 -f m4af -d 'aac '

    mb=300; diskutil eraseVolume APFS myramdisk `hdiutil attach -nomount ram://$((mb*2048))`

"superior" ... It looks silly to include such a judging adjective in the description of a comman line utility. I don't need "subtle" Apple ads on the command line. And aac is about the last format I would choose, encoding my audio in.

I think those are the commenter's descriptions, not Apple's man page synopses. My system has

     afconvert -- Audio File Convert
     diskutil -- Modify, verify and repair local disks.
