I see your point, and of course, that is one of the tenants of identifying true lossless compression. Actually, Mani already posted some data that shows there is loss. However, does that mean that Tidal is lying and purposely providing false information to encourage audiophile signups? Maybe, or maybe not.

Go look up the history of DIVX videos. They were sold on encrypted disks that required paying rental fees to watch. Oh yeah, the bugger tracked each disk with a unique bar code too, and had extra encryptions on it besides the old style CSS. Yeah, absolutely. People bought the things too. When DIVX went out of business, the disks were unwatchable. And the opposition on the internet, the fears and outrage expressed, were all very much like this. Sounds a whole lot like MQA to me, except MQA has less tech resources and the record companies are going to exercise caution about how much money they put on the table. -Paul Anyone who considers protocol unimportant has never dealt with a cat DAC.

The Security module in Divix was broken, and ways to read DIVX discs were abundant during the time. The current DIVX is in part a joke, but also is playing on people remembering the name. And the DIVX fiasco of the late 1990s is exactly equivalent to the MQA talk. I think it was mid-2001 when all DIVX players and discs, including the ones that were supposed to play forever, just stopped working.

Paul R Posted March 12, 2019 Share Posted March 12, 2019 32 minutes ago, mansr said: What is the difference between a proprietary encoding like MQA and something you would qualify as DRM? A "proprietary encoding" *may* be used in an implementation of digital rights management, but it is not digital rights management in and of itself. For example, I have software the does proprietary encoding of information to transmit. The reason is purely for speed, has nothing at all to do with managing who can use the information. That kind of management happens externally to the data and the transmission. You can also implement DRM without a propriety coding. For example, a player may check a serial number to validate you are authorized to decode and play some media. None of that requires proprietary coding. This also happens all the time. DRM is a system that is specifically designed to restrict access to material based upon ownership and/or rights granted by the copyright or IP owner. That does NOT appear to be what MQA is, though I grant you, it absolutely *does* have the capability to be used that way in a DRM system. Can MQA be used for evil purposes? Probably, but then, the same can be said for most things. I am honestly not trying to argue for MQA, but separating out facts from the hyperbole on both sides is incredibly difficult. Does make for good conversation though. -Paul daverich4 1 Anyone who considers protocol unimportant has never dealt with a cat DAC. Robert A. Heinlein Link to comment

For example, a player may check a serial number to validate you are authorized to decode and play some media. None of that requires proprietary coding. This also happens all the time. You can't have DRM without a proprietary element. Some schemes use a (mostly) open format encrypted using a key known only to the owner and the licensed decoders. That key is the proprietary part here. Using a secret encoding is, for the purposes of this discussion, effectively the same as encryption with the entire proprietary decoder as the megabyte-sized key. It won't have the properties of a true encryption algorithm, but reverse engineering it is at least as difficult, and that's what matters here. troubleahead 1 Link to comment

True, but I think I would put up with the slight crap in 24/96K, if the crap is merely what Mani found. -IF- (big if here) it meant I had access to more and better quality recordings. The failure to follow through with that is what really annoys me about MQA. I can live with some compromises, if I get better and more music. I suppose I should be grateful they are failing at that, it sure puts less of a dent in the music budget! -Paul Anyone who considers protocol unimportant has never dealt with a cat DAC. Robert A.
