[sdiy] converting data to audio... (WAY OT, sorry)

[James Husted]

All my MD recorders have an optical in. I would imagine that it would be the
easier input to use. No need to convert to audio at all. Now I must admit
that most portable MD players don't have the optical outs needed to playback
the data, but the console units do. The new Sony Viao MX series of desktops
has a MD recorder (a 32X version at that) built in. Maybe it will be offered
as an add on later (can't find it as one on their site now).
