It's a very good article which shows up again and again. Think it's 2040, singularity reached. AI runs the world and on HN we have this article popping up very frequently like every hundred Planck time unit .

#272Though as others have noted CD quality won't improve a terribly mastered recording from the loudness wars.

Exactly if it’s mastered wrong the nitrate has nothing to do with the issue this music would sound just as awful cut to vinyl from a bad master. Now you just can’t hear beyond 22050 so 192 is insanely wasteful. But poor mastering is absolutely the core issue not encoding algorithms
Actually, no, it might sound better cut to vinyl. Remember, vinyl doesn't have the frequency range or dynamic range that digital audio does, and it has to be mastered using the RIAA Curve because of the properties of the medium. One factor here is that the stereo separation on vinyl can't be too large, or else the needle will literally jump out of the groove! In short, you can't just take CD music (no matter how well…
There's nothing extra in a 192kHz signal that would help with the vinyl mastering process. You could make a technical argument for the benefits of a 24-bit source, but in practice even those benefits would be utterly swamped by the SNR of vinyl.

It is a good article, and since the misunderstandings are persistent in the same way a lot of other commercially exploited mysticism is it remains a relevant one as well. Having said that and to try to add on something new to these discussions, since you brought up this: > Think it's 2040, singularity reached.

True, except that few microphones provide a useful signal over 20kHz, and in the case of produced music, that segment of the signal was never heard or "signed off" by the original artists/engineers and therefore can't be considered part of the artist's intent.

I personally read the article to be addressing 192 kHz as a consumer of the music, I have a feeling for those producing (or mixing, etc.) it's a bit different. It's kinda like how there's advantages of recording at 8k, better cropping, supersampling, etc. But for the average consumer there's no perceivable difference between the pixel density of 8k footage and 1080p footage on their 7" screen anyway.
Yeah, the author is not arguing against using 24 bits when recording, just when distributing to end users. If the producer is planning to slow down the audio (and wants the ultrasonic components to become audible), then recording at higher sample rates makes sense, and the author doesn't address this; probably this is pretty rare in practice. You'd also need ultrasonic-capable microphones. The much more common operat…
No, it's literally excluded from consideration in the article's title. This is about music downloads, not music production.

I'm not that concerned, 256K mp3 has been good enough. Although it wouldn't be hard to automate a conversion to another format for my entire collection, given that I have lossless originals.
If I have a large FLAC collection and want to export the whole thing to MP3 or AAC copies, what would I do to automate that?
Re: 24/192 Music Downloads and why they make no sense (2012)
#277Problem with music sounding bad doesn’t really have much to do with the distributed format: V0, V1, or 320 mp3s should sound pretty much the same compared to 16-bit flac. You can only the difference between mp3 and flac at shitty bitrates no one uses anymore (like 120). The reason why a lot of recent digital music sounds bad is because of the intentionally terrible mastering. Since everyone is listening of crappy ear…
Also, I'm a little bit surprised that nobody focuses on more "out of the box" perception of sound. One can absolutely sense hgh frequencies, personally feel kind of like pressure where you can't pop your ears to equalize. Playing around with this feeling adds emotional tension and color to tracks.
Also, interference patterns are perceptible, and they sound kind of... Different from pure tones, idk.

#278Should this have a (2012) tag? Neil Young did end up releasing music in this format with his Pono player, which failed[0]. [0]: http://www.noise11.com/news/r-i-p-pono-neil-young-kills-off-...
Re: 24/192 Music Downloads and why they make no sense (2012)
#279The only rebuttal to this that I have found compelling is that 24/192 downloads make sense if you are going to sample the music in your own creations. Recording and mixing with extra dynamic range, combined with only needing to low-pass once at the end has demonstrable advantages. Of course this was a response to marketing that was definitely not targeted at samplers, so it's not so much of a rebuttal as arguing at c…
Yes, adding any sort of nonlinear distortion to audio will make frequencies depend on other frequencies, i.e. audible frequencies in the output of an effect can depend on supersonic frequencies in its input. For example, if you add a 100 kHz sine wave through a high-gain guitar amplifier, you'll definitely be able to hear it. I didn't really see a mention of this point in the article since there was no "So when do yo…
In most sensible systems, super-sonic content should be filtered out before it has a chance of doing nothing other than risking the fidelity of the final output.
As for your quip about a 100 kHz sine wave sent through a guitar amp, what you'd be able to hear are the distortions and subharmonics which are below 20 kHz—and if they're desirable in the recording they would need to be captured as their sub-20 kHz components. Capturing the >20 kHz components will do nothing but make the sound wildly and randomly inconsistent depending on the consumer's system.

#280When I casually researched the upper limit of human hearing, I came across something that mentioned that some people can detect lowpass filtering up to 27khz. That's less than half an octave over the "traditional" 20khz limit. Even the 20khz limit is more of an average then a strict biological limit. It also means that a sampling rate somewhere at 54khz is the "ideal" limit when trying to pick a sampling frequency th…
