Audiophiles huh
This is why I only listen to audio formats that add information to the music, not degrade it by taking away.
Don't. Don't give them ideas. TruMotion like frame interpolation is fucked up enough.
ChatGP3 Ultra Lossless
I went to school to be an audio engineer and audiophiles amuse me. While it is true that expensive speakers and FLAC and so on will make music sound better than it would on the cheapest stuff- we mix so it will sound decent on the cheapest stuff. We never mixed with you guys in mind. When I was doing it, we were keeping mp3 players in mind. These days, most music is mixed with streaming in mind.
My professor told us to take our mix out to our cars and drive around somewhere noisy and listen to it and then go and remix it after that based on what you heard.
Sure, there are exceptions. Not very many of them. Because companies want to make money from albums and they know most of the people listening to the music aren't going to be listening to lossless audio on $4000 speakers.
I find it especially amusing because, until the digital era, all the greatest music that was recorded since multitrack recording started in the 1960s was on bits of magnetic tape held together with bits of scotch tape and the engineer prayed that nothing would go wrong when it they were making the final two-track mix. It is highly unlikely that "what will this sound like on super expensive equipment?" was given consideration.
When I was in a band, we had our albums professionally recorded, mixed, and mastered, but we had a pretty decent set-up in the studio. After every practice, I'd do some rough mixing and burn us each a CD to listen to in our own cars and email MP3s for those of us who used devices. We'd take that and decide what needed to be fuller, what was getting lost, etc. and change any arrangement as necessary. Of course we might do more layers in the album itself than we could do live (well, without sampling machines going constantly and whatnot), but we still wanted to make sure we had at least the basics of where we thought people would listen to us.
Some editions are edited with audiophiles in mind but youre correct, most aren't and since about 30ish years the mixing is made to be less requiring.
Audiophiles are flat earthers for music.
They really obsessed over something and need to feel superior about it. They're harmless at least.
Unless of course you're googling about speakers for a TV, in which case you're about to get some terrible advice from some middle aged dude who's really pissed about soundbars existing.
As a middle aged man who bought a sound bar once, planned obsolescence sucks.
What's the equivalent of people that buy ultra high-end stuff to trick themselves into getting high and orgasming from "binaural beats"?
Christopher Nolan certainly does not mix his movies for the cheap stuff...
I think people get a little silly about it when you get above maybe 192kbps, but there 1000% is a huge difference between a 128kbps mp3 and a 192kbps mp3, and I would take a blind test every day of the week to prove it.
128kbps mp3s sound like aural garbage. It's like when you go to a wedding, and you can tell that the DJ just downloaded "Pachelbel's Canon" from KaZaa because when played over the PA, it sounds like someone farting into a microphone.
Are we talking about movies or music? Movies are mixed to sound good in theatres and then they are later remixed to sound good on at least cheap surround systems, but, again, they aren't generally doing it thinking about the people who spent $4000 on their system. And, again, the chief concern outside of the theater these days is audio for streaming.
I am not denying that a $4000 home audio system will sound better than a $100 one just by virtue of at least some of the components not being cheap Chinese crap, but I doubt even Christopher Nolan is ensuring his Blu-ray releases (or whatever) sound best on expensive audiophile systems. There's a point of diminishing returns here.
Aside from the Christopher Nolan thing, I was referring to music.
What I am saying is there's a point of diminishing returns. That point might be a 192kbps mp3, but there is still a point where 99% of people or more will not know the difference and there's no money in marketing to that 1% who will.
converts mp3 to flac

::: print vinyl from flac :::
Every time I see audiophile stuff it makes my expetactions of them dig a deeper and deeper hole.
Why is it always some snublord jerking themselves off over they 25k setup, like their ears are blessed by Zeus themselves.
If your pre amplifier isn't laid on cones carved from the purest quartz inlaid with gold, are you even really an audiophile ?
I find sapphire to be quite superior to quartz, actually.

I once realized there are audiophile speaker cables that cost hundreds of euros per meter because they are "burnt in" with some kind of awesome machine that pushes a specific amperage through it for a specific amount of time. I'm sure they improve the sound quality tremendously.
Zeus can hear a duck ovulating 100km away
He needs that ability, ok?
He obviously is right! I have a mechanical keyboard because it transmits better key presses. Aviator connector helps reduce the noise as well.
Technically, an issue with lossy formats is if they get saved, moved, and/or re-encoded then there is a risk of media degrading over time, over iterations. So you could potentially hear the difference.
But FLAC is lossless.
If the user likes the MP3 sound better then clearly they actually enjoy the lossy hum and buzz of compressed audio. I'm sure they would enjoy Vinyl.
Yes, transcoding. At least re-encoding, I'm not sure if simply moving the file degrades it...
All of this talk is making me miss what.cd. You'd get the boot if you uploaded a transcode
What.cd was the greatest collection of obscure music the planet has probably ever seen. I dont even particularly care about lossless codecs, I was fine with 320kb/s mp3 as it was more convenient but even their mp3 rips were way better than other places, and you knew everything would be tagged and sorted correctly. And they had EVERYTHING you could think of, it was wild.
In the context that automated systems will compress files for transfer to save bandwidth then it could potentially result in loss.
I like to witness this grey area in between misconceptions that comes up with a hybridation of absurd takes and obvious truth.
It's a file, if you get it fucked by copying it will just break, not "degrade" in sound quality.
If you reencode a lossy encoded file you will turbofuck it, obviously.

lol. They can’t hear the difference even with the most expensive equipment. The resultant signal from decompressing a FLAC phase cancels with the original signal if you invert it. Meaning they are indeed 100% identical. Lossless, dare I say.
Literally all it does as a file format is merge data that is identical in the left and right channel, so as not to store that information twice. You can see this for yourself by trying to compress tracks that have totally different/identical L and R channels, and seeing how much they compress if at all
Interesting. It must do more than that though -- for example, FLAC offers different compression "levels", which you choose when encoding. To my knowledge all of them are lossless, but what do the levels do if it is only merging identical channel data?
You’re absolutely right about that. My use of “literally all it does” was employed poorly, and is a pretty extreme oversimplification
There’s a whole mathematical thing happening with FLAC generally, regardless of L/R channels, where it replaces your original waveform with a polynomial approximation of it + the differences between that approximation and the actual. When played back together, those two things always result in a perfect recreation of the original.
The various compression levels you can choose from essentially control presets relating to how sophisticated those approximations can be, thus cutting down on the amount of differences that need to be stored.
The reason you may want to play with these settings is somewhat outdated now. But a higher level takes more time to encode, results in a slightly smaller file size, and also takes slightly more processing power to decode. Any modern piece of equipment can handle the maximum setting with no issues.
But yeah, as a result of these processes (rather than as the prime goal explicitly, if that makes sense), it does joint-encoding and merges anything from the L and R channels that can be merged. This enables it to pull “identical” sounds from L and R even when the data itself is totally different, which is actually more common than not in music due to the use of multi-channel effects such as reverb.
In the end, a massive amount of the space saved as a result of the compression in typical music comes from removing duplicate information from the stereo field. But all sorts of funky stuff would happen if you opened up a DAW and started contriving different situations for it to compress
polynomial approximation seems like a weird choice for audio, is it really more efficient than a frequency based encoding?
also, it seems like audio compression formats have seen a lot less development in recent years than images have. I want to try encoding audio as a lossless jpeg xl now just to see how it does, I think it should be possible as jpeg xl supports extremely large image dimensions
It’s fairly well optimized for audio. Waveforms are usually continuous and relatively repetitive. The other really important aspect is how easily it can be decoded, so that it remains a usable audio file on potentially underpowered equipment.
Although I wonder if there exist some cases where other formats might do a better job
Thanks for the detailed explanation!
