Do these things deliberately have broken CIRC (L1 errors)?  They must sound
distorted, as when audio data doesn't survive level 2 - that's it.  Unlike
CD-ROM Mode 1 Form 1 (data) which has L-ECC (and retries), you're in the
land of data loss and frame interpolation.

Those would be lossily compressed.  You'd be better off making an analogue dub.
