So articles like these are based on the fact the we, the minority, are poorly informed? Furthermore in the youtube comment section, he makes the absurd claim that "in general open source is great for professionals, less for consumers. ". At the same time he is making video's how to run open source distributions on raspberry pi and NUC's. Does he understand all android phones exists thx to open source? He shows a very poor understanding of how software licenses and how open source works. What big step? Hans Beekhuyzen makes me... MikeyFresh 1 Link to comment

First, SACD still sells there. Second, they probably like the sound of DSD. Third, it had probably been mastered to SACD for archive purposes long ago, so the easiest way to make MQA would be to first convert the DSD master they have and prefer to PCM. I have a few hi-res Japanese remasters in PCM that were made this way, and they sound great.

Those waveforms show the raw signal coming from the laser pickup. It's one of those things that needs to be good enough. After that, improving it further makes no difference. In a CD player, this signal is sent through an edge detector and a PLL to recover the NRZI-coded EFM data. A second PLL regulates the rotational speed such that the recovered clock matches the crystal oscillator reference. Here's an image of the same signal on a Sony CDP-101 playing a cheap Naxos CD: As long as the central edge is unambiguous, everything will be fine. Link to comment

bambadoo Posted July 12, 2018 Share Posted July 12, 2018 Stereophiles coverage of HDCD from 1995 https://www.stereophile.com/content/hdcd-keith-johnson-pflash-pflaumer-michael-ritter Quote High Definition Compatible Digital® (HDCD®), the proprietary process for improving the sound of 16-bit digital audio, has finally arrived. More than a dozen digital processors using the technology are on the market, and the professional encoder used to master HDCD discs is following closely behind. Quote I believe HDCD is a great breakthrough in digital audio sound quality, and one that brings unprecedented resolution and musicality to home playback—all on a standard compact disc. Quote Pacific Microsonics, the Berkeley, California firm established to develop and market HDCD, has been reluctant to release much technical information about how the process works. Moreover, they've kept a low profile during their nearly ten-year development effort. Quote Michael Ritter: HDCD is a comprehensive process for greatly increasing the fidelity of a digital audio recording. HDCD is fully compatible with the existing standard for consumer playback, the compact disc, which is fundamentally a linear format with 16-bit resolution and a sampling frequency of 44.1kHz. We had to make HDCD compatible with this standard. Yet the goal of HDCD was to achieve a vastly higher level of fidelity—a level of fidelity directly comparable to the finest recording technology available—ie, first-generation analog master tape or direct-to-disc by record lathe. To do this, the HDCD process had to be a conjugate system. By that, we mean a system where all aspects of the recording and the playback decoding had to be controlled as much as possible. For that reason, the HDCD process wraps around both the A/D conversion and D/A conversion. At the same time, as a concomitant requirement for this overall level of fidelity, we had to be able to take the HDCD process and essentially cut it in half. That is, encode the recordings, but be able to play the recordings on any standard playback equipment and simultaneously hear not only no artifacting, but a substantial improvement in fidelity over what can be obtained with a commercially available A/D converter. We've been successful in achieving that. Hmmm. Heard it before? crenca 1 Link to comment
