I must admit to being completely ignorant of DSD audio. Is this format available on optical discs? If it is, how many minutes of music are available on a disc?
TIA

It is only available as DSD64 format on SACD.
DSD64 is 5,645 Kbps for stereo and it is 2.37 GB/Hour.
DSD128 is 11,290 Kbps for stereo and it is 4.73 GB/Hour.
Formats such DSD128, 256 and higher are only available through download.
Just to compare:
PCM 24/96 is 4,608 Kbps for stereo, at 1.93 GB/Hour.
PCM 24/192 is 9,216 Kbps for stereo, at 3.86 GB/Hour.
They both have been available on DVD-Audio or BR-Audio.
Thanks for your reply!
Wowzers! That's a lot of data just to hear a track.
In fact, it's so much data that it gets me to wondering if there wouldn't be a more economical way of improving the sound of a track, such as ending the loudness wars.
I mean, we can keep throwing bandwidth at our music, but if it is still compressed, then what is the point?

Technically, those PCM bit-rate figures can be reduced with lossless compression (w/o a loss in audio quality). Not sure about DSD.
is DST on many SACDs.
So I gather it can be compressed for streaming as well. Thx!
