With e.g. another arch's iso, it's
$ file install59.iso
install59.iso: ISO 9660 CD-ROM filesystem data 'OpenBSD/macppc 5.9 Install CD '
I don't think that being playable as a CDR has anything to do with it
- did it just happen to match one of the following magic(5) values?
$ grep -Fr 44.1 .
./magdir/animation:>2 byte&0x0C 0x00 \b, 44.1 kHz
./magdir/animation:>2 byte&0x0C 0x00 \b, 44.1 kHz
./magdir/animation:#>>>2 byte&0x0C 0x00 \b, 44.1 kHz
./magdir/animation:>2 byte&0x3c 0x10 \b, 44.1 kHz
./magdir/audio:>>>2597 belong&0xfffff0 0x0ac440 \b, 44.1 kHz
./magdir/audio:>>17 belong&0xfffff0 0x0ac440 \b, 44.1 kHz
./magdir/dolby:>4 byte&0xc0 0x40 44.1 kHz,
I have seen other files reported as "44.1 kHz"
when there was no sampling involved.
