    Default DSD CD vs DSD SACD?

    I am a little confused. I thought that DSD was a form of SACD. However, I have a Telarc copy of Vivaldi's Four Seasons on CD (non-SACD) which indicates that it is DSD and a copy that is SACD DSD of the same disc.

    http://www.amazon.com/Four-Seasons-M...r+seasons+SAcd

    Apparently there are non-SACD DSD discs?

    The one you linked is an SACD. There is no such thing as a DSD CD since the CD spec does not use DSD for encoding. There are becoming available for download DSD files. However, I don't think it is possible to burn these onto a CD and then play them back on an SACD player, but that is just a guess.

    It is possible the music was recorded by DSD, but if so it is converted to CD format for sale as a CD. Think of the CD as the MP3 version of the DSD file.

    DSD-CD means it was recorded from a DSD master but the high sample rate is dithered down to 44.1 kHz 16 bit PCM to be compliant with redbook players. A real or native DSD recording is gonna sound better. DSD is 1-bit with a sampling rate of 2.8224 MHz, or 64 times that of a CD.

    Just a FYI for those who may not know…

    SACD stand for Super Audio Compact Disc and is a proprietary disc format developed by Sony in the late 90's. DSD (Direct Stream Digital) is an open format that does not require licensing for selling or playing back the files.


    Some interesting reading at DSD Guide.

    http://dsd-guide.com/

    http://dsd-guide.com/technical-documents

    Blue Coast and others offer DSD downloads in DFF format.

    http://bluecoastrecords.com/tags/dsd-downloads

    A simple file explanation from DSD Guide faq.

    "DSD or Direct Stream Digital is a one bit recording format. DSF and DFF are 'kinds' of audio files that are delivered as downloads or read by software for playback.

    DSF has the ability to hold metadata and DFF doesn't, however, some players (Foobar) only read DFF files.

    In PCM recording, DSF and DFF would be similar to having .wav and .aiff files which are both PCM"


    Many DAC chips can decode native DSD but the input is not always provided. Some DIY’ers have modded their CD/SACD players to export native DSD off SACD’s to their DIY DAC’s or via DFF from their 'puties hard drive. ;)

    My bad, forgot....

    On a Telarc CD that has been DSD-mastered, it will still display the DSD logo. However, there are other DSD-mastered CDs, like those of Elvis from Sony, that don't.

    DSD was originally developed by Sony to archive master tapes in a digital format. When Sony figured that it can re-sell the music again to the consumers, it developed SACD. The rest, as it goes, is history.

    Thanks for the info and clarification.
    I was a bit confused about this format myself.
