Re: Apple Music Announces Spatial Audio and Lossless Audio
#222Who knew I would be locked into Spotify not by the music quality, but by playlists, friends, apps using it, and their Discovery mechanisms. Apple and Tidal may have awesome quality, but apps like https://musicleague.app/ have gotten me through Lockdown, and it turns out that these value props are very strong. I always thought I would instantly switch to a service for its audio quality, but then again, I can also buy…
Agreed - Spotify's UI is bad and getting worse, and its quality is meh, but its discovery features are top notch and it has the biggest catalog. I have audiophile equipment - $900 MSRP Hifiman headphones, discrete DAC and amp - and I tried Tidal to see if I could hear a difference. 99% of the time, I can't... and Tidal's MQA format is questionable anyway. (Not sure about Apple's "ALAC" either.) I used a playlist impo…

#223Existing spatial audio on iOS+AirPods puts the center channel (dialog) coming from your device, which makes sense since you're actively looking at it.
But I listen to music while walking around the house. I'm constantly changing orientation.
Does this mean the center channel will always be directly in front of me and therefore the "band" will always be moving/panning with me?
That seems like it would destroy a big part of the spatial audio appeal in movies, that the sound stays in the same physical location when you move your head. But if they don't, how do they decide where the sound comes from?

#224Wouldn't lossless Audio need to be some kind of analog? Or some fourier transformations? Isn't the quantization of digital already a loss over the continous nature of sounds? I have no clue about audio.

#225Earlier quoted context omitted.
ALAC and FLAC are technically very similar formats [1]. Both are bit-perfect. Compare with MQA which is utter garbage and has absolutely zero to do with losless. MQA is actually, objectively worse than 16 bit audio CDs. An abject failure backed by an aggressively anti-science company backed up by a bunch of lawyers. [1] Both encode a PCM stream using linear prediction while storing the difference between the predicto…
Just to add to this comment, the video breakdowns I've watched on MQA are interesting listens even as someone who doesn't use Tidal. https://www.youtube.com/watch?v=pRjsu9-Vznc -- Critque of MQA https://www.youtube.com/watch?v=zwZ5hDzQ5Jg -- in defense of MQA At the end of the day, people should listen to what they think sounds good (is this an opinion?). If a placebo makes someone enjoy something more, is it really…

> There have been tests showing we cannot hear the difference between minimally lossy audio (e.g. mp3 320kbps) and lossless. But Balvin can. And it sounds "bigger and stronger". On the contrary, you can actually do these tests yourself ( https://www.npr.org/sections/therecord/2015/06/02/411473508/... ). I and many others running good high end gear can repeatedly score well on these tests. Of course, it's not only the…
> Of course, it's not only the compression that's at stake-- it's also the mastering quality. HN threads on lossless music so often descend into "well, you couldn’t hear the difference". But historically a key reason for people to prefer e.g. SACD releases of recordings is not because one can hear the extra frequencies of this format, but because the SACD release – being targeted at people with a good stereo and sile…

#229From the article: > J Balvin said: [...] With Lossless, everything in the music is going to sound bigger and stronger but more importantly, it will be better quality. [...] There have been tests showing we cannot hear the difference between minimally lossy audio (e.g. mp3 320kbps) and lossless. But Balvin can. And it sounds "bigger and stronger". The extra quality of lossless is nice when mixing/remixing the sound, a…

> I and many others running good high end gear can repeatedly score well on these tests. I, too, run high-end gear and cannot. The problem scope isn't simply reproduction accuracy, it is also one of taste: Different compression can elevate/alter parts of the sound, and your opinion may not lean to the highest bit rate but rather some other coloring of the music. The fact you've run this test "repeatedly" actually hur…
Why does any of this matter? The point of a blind ABX test (and the whole question) is to see whether you can tell the difference between two formats. If you can, you can. Personally, I stop being able to tell somewhere around 200 kbit MP3s (with cheap equipment), anything above that is wasted space. You can run the tests as much as you want, if the hypothesis is that "people can't tell the difference between lossles…
Having lossless copies is still useful for storage and later transcoding. Even if you can't hear a difference between a 192kbit/s MP3 and a higher bitrate lossless file, you might be able to hear one after reencoding the MP3 using another lossy format.
