    Hi-resolution audio, especially for streaming. The general idea is that listening to digital audio files that have a greater bit depth and sample rate than CD (24-bit/192Khz vs 16-bit/44.1 KHz) translates to better-sounding audio, but in practice that isn’t the case.

    For a detailed breakdown as to why, there’s a great explanation here. But in summary, the format for CDs was so chosen because it covers enough depth and range to cover the full spectrum of human hearing.

    So while “hi-res” audio does contain a lot more information (which, incidentally, means it uses up significantly more data/storage space and costs more money), our ears aren’t capable of hearing it in the first place. Certain people may try to argue otherwise based on their own subjective experience, but to that I say “the placebo effect is a helluva drug.”

        Up to a certain point, yes. >192k AAC / OGG / Opus sounds just as good as FLAC in a blind test, though. Even with good equipment.

            Back when a 4 minute song was like 1.5MB so you could fit more music on your 256MB mp3 player because you could not afford an iPod.

            Oh yeah. 128k rips from back then were rough. MP3 has gotten somewhat better since then, to be fair. V0/V1 VBR is still perfectly fine to listen to; it’s just not as efficient as the newer codecs.

            Yeah they do, although CBR performs noticeably worse than VBR with Lame MP3. As I mentioned elsewhere, MP3 @ V0 or V1 VBR sounds just as good as the above. I just personally haven’t used MP3 for years because the newer codecs are more efficient.

      I’ve always kinda wondered about this. I’m not an audio guy and really can’t tell the difference between most of the standards. That said, I definitely remember tons and tons ‘experts’ telling me that no one can tell the difference between 720p and 1080p TV at typical distance to your couch. And I absolutely could and many of the people I know could. I can also tell the difference between 1080 and 4k, at the same distances.

      So I’m curious if there’s just a natural variance in an individual’s ability to hear and audiophiles just have a better than average range that does exceed CD quality?

      Similar to this, I can tell the difference between 30fps and 60fps, but not 60 to 120, yet some people swear they can. Which I believe, I just know that I can’t. Seems like these guidelines are probably more averages, rather than hard biological limits.

        It’s a fair question. Human hearing ability is a spectrum like anything else, however when it comes to discerning the difference in audio quality, the vast, vast majority of people cannot reliably tell the difference between high-bitrate lossy and lossless when they do a double blinded test. And that includes audiophiles with equipment worth thousands of dollars.

        Of that tiny minority who can consistently distinguish between the two, they generally can only tell by listening very closely for the very particular characteristics of the encoder format, which takes a highly trained ear and a lot of practice.

        The blind aspect is important because side-by-side comparisons (be they different audio formats, or 60fps vs 120fps video) are highly unreliable because people will generally subconsciously prefer the one they know is supposed to be better.

        i think hi res is for professional work. If you’re going to process, modify, mix, distort the audio in a studio, you probably want the higher bit depth or rate to start with, in case you amplify or distort something and end up with an unintended artefact that is human audible. But the output sound can be down rated back to human levels before final broadcast.

        O couse if a marketing person finds out there is a such a thing as “professional quality”. . . See also “military spec”, “aerospace grade”

          Yeah to expand on this, in professional settings you’ll want a higher sampling frequency so you don’t end up with eg. aliasing, but for consumer use ≥44–48kHz sampling rate is pretty much pointless

        I think this is the case where certain people simply can’t see it here the difference.

        I collect video game and movie soundtracks and the main difference I can hear between a 320kbps VS a FLAC that’s in the 1000kbps range is not straight up “clarity” in the sense that something like an instrument is “clearer” but rather the spacing and the ability to discern the difference where instruments come from is much better in a Hi-Res file with some decent wired headphones (my pair is $200). All this likey doesn’t matter much though when most users stream via Spotify which sounds worse than my 320kbps locally and people are using Bluetooth headphones at lower bitrates since they don’t have better codec compatibility like aptX and LDAC.

      It’s for all the pets at homes hearing the same audio, now with original insects and birds outside and mice in the walls.

      A lot of it will depend on your output device; cheap headphones will wreck audio quality.

      I remember the bad old days when .mp3 files for streaming were often 128kbps (or less!); I could absolutely hear audio artifacts on those, and it got significantly worse with lower bitrates. 320kbps though seems to be both fairly small, and I can’t personally tell the difference between that and any lossless formats.

      Right you are, but don’t start telling everyone so I can’t silently download my lossless albums from Tidal, Deezer and Qobuz anymore.

      All you really need is the Nyquist frequency of human hearing to know. That’s a good breakdown for audiophiles I’m sure but it is broadly as simple as the Nyquist frequency.
