jernikfra Posted January 29, 2007 Report Share Posted January 29, 2007 (edited) Please forgive me for accidentally posting my last post so many times.I'm pretty new to this, and didn't realise, going back to edit would cause each post to show up.Won't happen again.Administrator:Please delete my first three posts! Learned my lesson.Thanks in advance! Don't kick me off the forums please, I love MD's!I've got another question I was hoping someone could answer.For a while now I have been doing digital copies of digital recordings from one MD deck to another MD deck through optical connections.I won't go into details on how i do this, lets just say, that dreaded SCMS is easy to defeat.the question i had is regarding audio quality.I'v done many listening tests to determine any difference between the original MD and the digital copy.i have been unable to notice any difference between master and slave.they both sound awesome.I assume that is is due to two reasons. 1.A digital recording will sound the same as the source, since it is digital, and 2.The recording deck has nothing left to throw away.In other words, when the original recording was made, the atrac circuit kept all the relevant music, and threw away the stuff you can't hear.When the 2nd deck was given the digital signal, their was nothing left to throw away, since it had already been done first time around, so it just copied bit for bit the signal and now we have succesfully moved the song to another md and kept the original also.Hoping someone is also doing this and can shed some light on this.I have done an experiment doing the above with a song and then comparing it's quality to the same song, an SP digital recording uploaded from an MZRH1 to sonicstage in PCM, and then downloaded in SP to and MD.I was again unable to notice a difference in quality.My next experiment will be to compare that same digital copy of an MD, this time to an SP digital recording uploaded from an MZRH1 to sonicstage in PCM, and then digitally recorded from the USB to optical output adapter of my computer to the optical input of an MD deck in SP.Will let people know the results!

raintheory Posted January 29, 2007 Report Share Posted January 29, 2007 (edited) Interesting... SP "compatibility mode" via SonicStage is actually LP2 quality ... 132kbps instead of real SP 292kbps...I would hope your next test will yield better results..

eriktous Posted January 29, 2007 Report Share Posted January 29, 2007 Copying an MD from one deck to another through an optical connection won't give bit-for-bit identical recordings. The difference in quality will be so small, however, that most people won't hear it.Only after making several repeated copies of copies will the sound start to deteriorate perceivably.(This is Sony's claim. I haven't tried this myself, but their reasoning sounds logical to me.) Quote Link to comment Share on other sites More sharing options...
