Audiophiles be like : memes

The meme is literally correct. when you make an audio file into an mp3, it takes some of the sonic information that our brains are bad at noticing and just...completely removes it(to save storage space). if it's a high quallity mp3 its essentially completely unnoticable. That's why it's psychoacoustic, it uses psychology to fool your brain into thinking it sounds better than it does, litterally.

Psycoachoustic is basically just a big word for taking into account how our brains deal with what we hear.

Also I'm not saying mp3 is bad, in fact I think the opposite is true. I think it's good to think of it like being the .JPG of audio, you're not getting the original quallity and that's the point and unless you need to do manipulate that audio file and its a reasonable quallity then you likely won't notice the difference.

Ogg vorbis (.ogg) is a better codec though IMO.

You successfully managed to ignore the joke entirely.

actually I found the joke to be funnier because it was litterally technically correct.

You do good, internet is so analphabetic these days, we need more correctors like you. Look I don't even know how many typos i did in this comment so correct me. I like when people tell me what's wrong, but literally no one does that.

I think people generally have been taught to accept lower quality for convenience and even I, the guy who cared a lot about quality and spent for it, have acquiesced. I want full quality, uncompressed everything. But I stream my movies and stopped buying Blu-rays. I still buy CDs, but I’m an old man who likes album art.

[–] leisesprecher@feddit.org 9 points 3 months ago (1 children)

Humans actually ignore certain bad attributes of music if that's what they're used to.

There has been a study a whole back and essentially, if you're old, you are much more tolerant to the typical tape noise and hissing than young people, simply because that's what you grew up with. MP3s and digital compression in general sounds really bad, though. For young people, the opposite is true, they can ignore compression artifacts, but not tape hiss.

MP3s and digital compression in general sounds really bad, though.

I often wonder if this is because it’s MISSING the tape noise and record scratches. I’ve heard lots of people say that vinyl is better audio quality than CD, which is simply not true. I suspect that feeling of it being better audio quality comes from it being what you’re used to.

[–] AmbientChaos@sh.itjust.works 4 points 3 months ago (1 children)

I think in general the reason people think vinyl sounds better actually isn't a quality judgement and is down to the different mastering vinyl typically receives. Streaming music sources are typically mastered very loud with the dynamic range reduced as a result, this is to compete with all the other tracks mastered for loudness. Loud typically subjectively sounds better when A/B comparisons are done, like when a streaming service serves up a bunch of random songs. Because vinyl has the privilege of not being shuffled with other productions and due to the physical nature of the medium it typically receives a bespoke mastering of the content. This bespoke master typically has a better dynamic range because it doesn't have to max out loudness. In my experience I prefer the vinyl mastering of an album versus the streaming mastering 90% of the time. There are some stinkers though :P

[–] TheRealKuni@lemmy.world 3 points 3 months ago* (last edited 3 months ago) (1 children)

I meant (in MY comparison) specifically compared to CDs, and I would hope an album bought on CD is still mastered for that album. CDs are lossless, vinyl is only that high of quality the first time it’s played (and even then introduces noise).

Yeah, streamed versions aren’t going to be as good.

[–] AmbientChaos@sh.itjust.works 4 points 3 months ago (1 children)

Ah, I see! Like I said though, not necessarily a quality difference but a mastering difference. It's not that the mastering isn't made for the album/songs, it's just the target medium of the masters that are different and the nature of the mediums the masters are destined for.

This obviously comes down to the specific album, but from what I understand it is common to have just two masters, one for digital (streaming/CD) and one for analog (vinyl). A huge driver of this is that you CAN take a streaming master and put it on CD but you CANNOT do the same for Vinyl, because of it's physical limitations. A streaming master on CD functions perfectly while a streaming master on vinyl has a good chance to cause the needle to jump tracks and have distortions because of the loudness the vinyl can't handle. That's why maybe only vinyl gets a special master, because the medium demands it.

Of course there is nothing stopping an audio engineer from creating that vinyl master and sending it for the CD and Vinyl!

Not trying to argue merits of either format though, I love and use both. I even stream music (gasp). I'm just an audio nerd info dumping haha

I was like that too until I realized that all media is compressed in some way. A digital recording is only ever as precise as the analog to digital converter that was used in the studio. Analog is only as precise as it's smallest distinguishable change. Eventually enough is enough and I was only wasting money.

In general I don't believe you can tell any difference between MP3 and FLAC if you listen to the audio at the intended sample rate.

Meaning that @44100hz with 8 bit samples; you can't tell.

Listening at higher sample rates with higher bits per sample; sure...there's lots of room for unwanted and even audible error. Audio interpolation algorithms are not miracles, not smart, and not even close to being finely psychoacoustically tuned to your ears in most cases.

If you say you can hear a difference...you are lying or you are cheating by playing back the MP3 over an audio pipeline with a higher sample rate and bits per sample. Anyone could hear the difference when cheating like that. Human hearing can span all the way up to 128Khz; but oftentimes most people can't notice a credible difference even at 96Khz.

But if you listen to a 44.1Khz signal via a 96Khz set of equipment; you'll pick out exactly when the audio output shifts between being 96Khz and 44.1Khz.

This is how you can tell when audio is a recording at a lower sample rate. Most hardware is capable of outputting 96Khz so long as you don't put older things in your audio chain (The pipeline from file to your ears, and yes this includes software and your operating system as well).

The problem usually arises when something is upsampled. Going from 44.1Khz to 96Khz is noticeable when you "Compress" the audio signal to boost apparent loudness. Most low-end equipment and unaware software will do this sort of operation automatically when upsampling your audio to make sure the process does not render your audio too quiet to hear. Your ears can hear frequencies being clipped or limited to a certain volume as well; which can also happen a lot to prevent certain issues. Because most people are unable to regulate this hidden software aspect of their playback chain; you can sometimes hear it.

Luckily if you spend some time with proper DSP software and/or hardware, you'll be able to unmuddle/unmix these mistakes in your chain. It does take time and patience; and you'll need a large blend of HQ audio (like FLACs or MQTTs) as well as your standard "downsampled" audio (like MP3s and other lossy tracks), and you'll be able to tweak things so that everything sounds good.

Software packages like Viper4Windows or Viper4Android are good starting points and are often easy to figure out how to use and offer a very wide and diverse range of controls you can use to adjust the audio to your needs and liking.

Because everyone's ears are different; there's also plenty of tools that claim to adjust for your individual ears...and those can be helpful as well in chasing your perfect flat audio response curve and equalizing things to your preferences.

[–] Kushan@lemmy.world 10 points 3 months ago

There's literally an entire industry of bullshit cables and devices designed to "improve" sound quality that demonstrably does fuck all. That's enough to tell me that most people saying they can tell the difference are probably full of shit.

[–] WereCat@lemmy.world 7 points 3 months ago (1 children)

Most of the time I can't tell a difference but with orchestra / classical music I can.

Also most of the time I listen to music when I'm in a factory with 75db-80db noise floor so it hardly matters how good headphones and source I'm listening to.

It's just at home where I can fully enjoy my flacs with HD 650... Not that I bother listening to them too often anyways.

I'll take good mp3 256kbps master over bad flac master any day though.

[–] Melody@lemmy.one 1 points 3 months ago

As someone who owns a similar set; I can estimate you're probably dealing with the upsampling issue due to an OS configuration issue. You should try listening to MP3s and FLACs at 44100hz sample rate for your comparison. Not 48000, not 96000.

[–] yardy_sardley@lemmy.ca 12 points 3 months ago* (last edited 3 months ago)

Not just mp3, all lossy audio formats use psychoacoustic analysis. That's how they figure out which data to throw out.

[–] arin@lemmy.world 8 points 3 months ago (1 children)

i feel insulted

[–] disguy_ovahea@lemmy.world 23 points 3 months ago

They shouldn’t be giving you so much flac.

[–] andrew_bidlaw@sh.itjust.works 7 points 3 months ago

I stopped bothering with loseless to save space. Guess what? The drive is as full as it was before.

[–] muad_dibber@lemmygrad.ml 5 points 3 months ago (2 children)

Does anyone know of any massive double blind study where they see what actual mp3 bitrate where people stop being able to tell the difference in quality?

I've tried and can't tell the difference between any 320kbps and lossless.

[–] mbirth@lemmy.ml 3 points 3 months ago* (last edited 3 months ago)

There was one where the guy behind it went to massive lengths so people couldn't easily distinguish the example files by other means than audio quality. Verdict was that people with more expensive equipment even preferred the sound of the MP3s (320kbps CBR). I think it was this one (Links to Parts 2 and 3 at the bottom.).

Somewhere else I've read that - for most humans - 256 kbps MP3s encoded with VBR-ABR using a high-end encoder are basically indistinguishable from the lossless original. Even at 192 kbps it's still more hit&miss than it should be. But I don't remember where I've read that.

[–] customley@lemm.ee 2 points 3 months ago

Did you try on Bluetooth headphones? If so you won't notice any difference because Bluetooth has very limited bandwidth and can't really handle anything more than a standard MP3 (unless you have Sony headphones which use LDAC).

[–] bitfucker@programming.dev 3 points 3 months ago (1 children)

Maybe slightly related, but does anyone know any good codec (beside FLAC) for ultrasonic recording?

[–] vfreire85@lemmy.ml 1 points 3 months ago (1 children)

ogg vorbis, already mentioned above.

[–] bitfucker@programming.dev 1 points 3 months ago

Alright, will check it out

They all ended up corrupted over time.

Sounds like a storage medium issue. Bit rot.
