In Reply to: RE: can a hi rez 96Hz 24bit album fit on a CD? posted by digda_beat on September 08, 2016 at 02:38:15
Even if you did write a 24/96 music file onto a silver disc it would not be a CD. The standard is defined by ISO 60908 which defines not only the data rate (16 bit, 44.1 kHz) but also how the data is written per frame, error correction, information layers for storing ISRC, CD text and so on.
Any disc that does not adhere to this standard is not a Compact Disc.
The logo saying 24/96 remastering means just (or only) what it says. The engineers transferred the original analogue tape to a 24/96kHz digital master which was downsampled, in turn, to produce a 16/44.1kHz production master to cut the glass master for the CD.
Classic album from Sir Rod. I must look out my old vinyl copy which I haven't heard since the year of release.

You are right about the CD International Standard. Furthermore, the capacity of standard compact discs would significantly limit the playing time with music of 24/96 digital resolution.Alesis introduced a different standard called CD-24 that enabled higher resolution up to 24/96 to be written onto a standard CD-R. It would allow only 19.7-minutes of music on a standard 650-MB music CD-R and 21.3-minutes of music on a 700-MB data CD-R. It was playable only in the Alesis Masterlink ML-9600 hard disc digital recorder.

Thanks John, interesting. Isn't this the machine that Michael Fremer uses to make dubs from his record player to play at various industry events?
Michael Fremer used a specially modified Alesis Masterlink at one time, although as Jeff Starr states, he has since moved on to different digital recorders.
I used the Alesis Masterlink to copy vinyl from 2003 until I upgraded to a TASCAM DA-3000 a couple of years ago. The Masterlink's highest resolution is only 24/96 whereas the TASCAM DA-3000 can record PCM up to 24/192 as well as DSD(64) and DSD(128). Nowadays I used DSD(128) to copy vinyl LPs.

Thanks John. I must say that Tascam recorder may be very attractive to me. The 2016 Proms season is just about to end and I am frustrated at not being able to have a permanent copy of some of the concerts broadcast on BBC Radio 3 HD. But I assume that I would still be unable to record streamed radio and would need to use an FM feed via the Tascam's analogue inputs?
As for recording to it from vinyl, I have read your enthusiastic recommendations over the past months and it may have a future for me too.
I assume that as you use DSD you do not (cannot) use any DSP software for e.g. de-clicking? Do you transfer the files produced to another player , say PC/Mac based, for replay or do you just go straight from the Tascam to your pre-amp?
Of course if I did get one I would have to find somewhere to put it and that is not easy for me these days as my available space is used up.
Best Wishes

Actually, I have never used click and pop removal software on any of my vinyl recordings, even when I recorded in 24/96 PCM. Therefore, going to DSD(128) was not a problem in that regard.
I transfer all my vinyl recordings to my computer for storage onto external USB hard drives. For playback of PCM files and DSD(64) files, I use USB flash drives plugged directly into my Oppo BDP-105D. For DSD(128) playback, I use USB flash drives plugged directly into my TASCAM DA-3000. I no longer use a computer for streaming digital.
Best regards,

It was at one time, Fremer had his upgraded.
Now I would think he would be using something else that he can include hi-rez and dsd.
I don't recall him mentioning the Alesis in the recent past.
