Neil Young is totally right that the fancy high resolution audio tracks shouldn't have ridic high prices compared to normal releases these days though. They should cost about the same as the normal releases, because they sound about the same and usually don't need special remastering.

Just as it is totally unrelated that DSD, instead of being a natural follow up to 16/44.1 PCM like 20/88.2 or whatever, uses 1-bit samples at several MHz. This requires serious additional tech to make it work somewhat well (DSP based noise shaping etc) that would be totally superfluous in a more conventional system design, but is novel and therefore much more defensible in patent courts. I am sure however that Sony's engineers were pursuing the best possible technical solution, they couldn't have had any other reason for designing DSD that way

Given his age and career, how likely is it that Niel Young could even hear the difference between a CD and a 64kbps MP3 recorded from a third generation analog cassette that had been high speed dubbed on the cheapest deck you could buy in 1982?

Keeping in mind how notoriously loud his 80s shows were, I just assume anything above 10k is quiet background noise fighting his admitted tinnitus.

DSD has a practical reason to exists; it's just for making DACs that play it cheaper and more power efficient, not for audio quality.

Your typical audio DAC takes a PCM sample, transforms it to a 1-bit signal at a higher frequency, then smooths the output to get the analog signal. It's small (=cheap) in terms of circuit area and power efficient since the transistors are always either fully on or fully off so they dissipate minimal energy. DSD as an input format would let you skip the upsampling parts and dithering parts of the circuit.

If they had gotten it as the audio track format in blu-ray, players would have been a couple of pennies cheaper AND they'd have license fees/barriers to entry for competitors.

(24 bit audio also has some practical uses. If you embed a 16-bit signal with 8 padding bits, it gives you 24dB of wiggle room to do digital volume changes without having to vary amplifier gain.)

Delta-sigma is a common way to build a DAC, yes. The questionable choice is making that post-conversion 1-bit stream (which would normally be an intermediate format that only exists inside the DAC) be what's sent from the recording studio to end users via distribution media (SACD, files streamed over internet, whatever). I haven't ever heard any good technical reason why this makes sense.

This doesn't make any sense to me unless you are conflating class-D amplification and DSD. Much like you don't need DSD to build a delta-sigma DAC, you don't need it for class-D power amplification.

quote:

Yeah but (a) who cares, that's barely any area / power these days and (b) lots of consumer audio gear would like to do some DSP on the signal (surround sound processing, for example) and I doubt it's easier to do that with a DSD input stream.

quote:

(24 bit audio also has some practical uses. If you embed a 16-bit signal with 8 padding bits, it gives you 24dB of wiggle room to do digital volume changes without having to vary amplifier gain.)

But you don't need 24-bit PCM in the distribution media to do this, just a 24-bit dac.

"Hi res" distribution media is basically a scam even if it's 24/96 PCM IMO. 16/64 is probably way more than good enough but the numbers aren't sufficiently bigger than 16/44.1 to be sexy I guess

DSD also imposes some significantly limitations on what sort of digital operations you can do to the sound. There is currently no EQ/room correction that works on DSD, in fact almost every single DSP plugin or effect works on PCM only.

That's why DSD has to be converted to DXD (which is PCM) if you need to do any kind of operations, other than very simple cutting or splicing.

The sheer inconvencience of DSD is the biggest mark against it, and are much worse than the relatively simple PCM to delta-sigma conversion done by the DAC.

There's a million things to pick apart in that but praising a cable for its "speed and precision" stands out to me as the most hilarious. Like there's some slow-rear end cables that the sound waves get stuck in and the music plays out of phase because the left speaker has a bit of a backup.

e: related since I saw it on TAS I have to hand it to Magico, they've really nailed the whole "make super expensive speakers that don't look like a minecraft Dalek or a refrigerator with holes punched in it" thing:

No, that is referring to physical speed and precision. The cable has a nickel-PFTE sheath that reduces friction for the fastest uncoiling and routing. Patented feed lips machined into the plug allow for lightning fast cable changes and drop-free release of spent cables. For the absolute fastest USB cable changes, you will also want to add the accompanying portwell to your system's USB ports:

Good comment on it though:

"
In the meantime I've given up on cables. When I want to listen to my audio, I call a bunch of players from the string section of the LA Phil, wrap them with high quality aluminum foil from Costco, arrange then in four lines with their arms stretched and holding hand to hand and then I have the ends of the line each touch the amp or the speaker terminal with their free fingers. The biggest concern is to avoid creating short circuits.

The wind ensemble guys are best for chamber works, the horns are great for french music and the bassists and celloists do justice to Russians. I'm still trying to get a set up for Rock and Roll, as the last set of rock musicians came drunk, kept short circuiting and triggering the amp's protection.

Oh, the LA Phil guys are great, but being union there's no way they'll stick around for the encore"

But what on Earth does the author mean when they write "the removal of support for the format signals an official shift in the industry."? What support?

The statement on Fraunhofer Institute's web page says:

quote:

On April 23, 2017, Technicolor's mp3 licensing program for certain mp3 related patents and software of Technicolor and Fraunhofer IIS has been terminated.

We thank all of our licensees for their great support in making mp3 the defacto audio codec in the world, during the past two decades.
[...]
What will be the consequence here? If I want to make software that uses mp3 encoding/decoding, would they actually forbid it?

I read the statement as "we used to require a licensing agreement for people to use our patented technology, but there's not enough money in it anymore to continue". Which sort of implies that they're not going to bother to hunt down and prosecute people who continue to use it. Which means usage might actually increase (even if I think it unlikely due to competing free codecs).

^ Yes, according to this page on the Internet, the last few patents are about to expire.

The consequence is that now any company who wants to make software or hardware decoders for MP3 can do so without worrying about paying the licensing fees. So, you can expect a slight increase in MP3 usage among small time outfits that currently had to stick with either a free codec or one with lower licensing fees. It also means that it's a lot easier to get "truly free" MP3 support in many open source projects that required users to provide their own MP3-handling libraries or programs before.

For instance, the popular open source audio editor Audacity currently doesn't support MP3 export in its default download. You need to specifically download LAME or a similar MP3 package from elsewhere to get the MP3 export functionality, presumably once the patent has fully run out the functionality will be fully incorporated to Audacity.
