Basically my option would then be to acquire an audio CD recorder with digital input and record the minidiscs (copy protection bit permitting) to CD from which I use cdparanoia et al to get the full information. Possibly putting the Hammerfall as pass-through in the middle, hoping that it will pass on the user/subcode bits while clamping down on copy protection. Yes, that sounds overoptimistic: there is no obvious reason why anything but PCM data should make it through its Totalmix. Or I hope that recording a copyright-bit plagued Minidisc will at least record _structured_ silence. In which case I can at least get the structure on CD. This is all rather icky. Does anybody using other operating systems know whether the situation is basically the same there? -- David Kastrup _______________________________________________ Linux-audio-user mailing list Linux-audio-user@xxxxxxxxxxxxxxxxxxxx https://lists.linuxaudio.org/listinfo/linux-audio-user
