In other words, the listener can still hear extremely low level content when that content is softer than the noise of the record/tape itself! Digital cannot do this Digital can do this just fine with dither and possibly noise shaping. How do you think 1-bit DSD can achieve 120 dB dynamic range below 20 kHz?

I just didn't want to muddy the waters by bringing-up dithering or DSD. I restricted my comments to LPCM Dithering should be used with LPCM. Your decision to ignore it makes the comparison skewed.

mansr Posted July 5, 2018 Share Posted July 5, 2018 10 minutes ago, gmgraves said: My conclusion was (and is) that digital - even CD, as a recording system, ultimately, is better than analog (vinyl and tape), but that differences between various productions from recording to mastering to actual manufacturing, can make it a crap shoot whether the best sound is from a particular vinyl record, a CD, a high-res download or an audio blu-ray disc, or an SACD. In any particular case, the winner, SQ-wise could be any one of the above. That part I agree with. Link to comment

I can't say that any digital recording solution I've heard matches these recordings on a good vinyl solution. Not saying that digital is necessarily inferior to vinyl, just that engineering skill in making the recording is make or break for also ran vs a masterpiece recording. I have neither a turntable nor any vinyl discs. The recordings you mention are surely wonderful. I never said vinyl can't sound good. However, digital sounds at least as good with far less expense and effort. Link to comment

Probably a higher percentage of total energy use than we do here on Earth. If the orbiters are included, it could well be the biggest consumer of energy. Link to comment
mansr Posted July 7, 2018 Share Posted July 7, 2018 1 minute ago, Ralf11 said: they use low bit rate comms AFAIK I'd bet the crawling is the biggest use on Mars ? The orbiters still use fairly powerful transmitters to reach Earth. The MRO bandwidth is up to 4 Mbps. That's more than you can get in some (rural) parts of the US. Link to comment

I'm not certain one way or another, but it could be interesting to find out. Maybe the info is somewhere on the NASA website. Link to comment

The station transmits data to whichever TDRS spacecraft is in view, which, in turn, transmits it to ground terminals before it reaches a data center like mission control in Houston Where did you find that, and which "station" is it referring to?
