Because it was smaller than the FLAC option I presumed the ALAC was all 16/44.1 and the FLAC was all hi res. I downloaded both to see, and was wrong on both accounts.

The FLAC consists of this assortment of songs:

1) 24/96

8) 24/48

34) 24/44.1

44) 16/44.1


The ALAC consists of this assortment of songs:

9) 16/48

78) 16/44.1


So all of the 24-bit songs were converted to 16 bit and the lone 96kHz file got a power-of-two sample rate truncation. Fair enough.

It's worth noting the Lavf encoder (based on ffmpeg?) used to create the ALAC files was set to 0 compression, which means they could have all just been AIFF with "no" relative file size penalty. This was discovered by noticing the bit rates --- all 1411kbps for the 16/44.1s and 1535kbps for the 16/48s, same as if they'd been AIFFs. I took one of the supplied ALACs, made my own ALAC from it and the file size shrank to 1/3.
