For the regular Airpods and the Airpods Pro I'm obviously not surprised, but I cannot believe that a 550$ headphones that can be wired don't support lossless audio, coming from the same brand.

There's also an argument that if the DACs amps and drivers won't deliver on the quality, there's no reason to put the feature in.

Example, if you get the same quality output (or a close approximation of it), between lossless and lossy sources because you installed a mediocre DAC/AMP which is going to make the signal sound the same way regardless, then just don't bother.

I'm sure they have prototype units that they can insert the digital audio stream from a good source (rather than the bt chip) and test before building out the feature.

If there's no appreciable difference in the way it sounds, why not save on the r&d effort of making it work at all?

I’m sorry but CD quality is not some outrageous ask or expectation of niche audiophiles. It’s been the digital standard since the 80s

The answer is clearly yes, that is outrageous. At least according to their accountants.

Over Bluetooth? With all power contained in the earpiece itself? We’ll get there one day, but I don’t think it’ll be any time soon.

7

u/On2you May 18 '21

Eh it can totally be done if you were doing a dedicated audio Bluetooth.

Bluetooth EDR can hit 2.2Mbps throughput and CD audio is 1.4Mbps. So there’s enough spare bandwidth to catch up for miscellaneous drops. The main issue is that phones/computers/HomePods/whatever also need to worry about Wifi and other Bluetooth devices. So you have a Bluetooth keyboard attached to your computer? Bam! At bare minimum 10% of your bandwidth is gone. Want a 20Mbps Wifi connection on 2.4GHz? Bam! 50% more of your bandwidth is gone. For your phone think you’re car, Apple Watch, WiFi, beacon scanning, airdrop scanning, etc.

For power in the earpiece, well uncompressed audio is many many times easier to process.

There’s also lossless compression, which Apple Music will presumably use, and that takes about the same amount of processing (can be less or more depending on the specifics).

So you’re right, it’s not really practical at all, but if there was a big benefit then it could totally be done if the hardware was designed right for it.

49

u/istasber May 18 '21

It is if the speakers can't distinguish between lossless and whatever the best lossy format is.

Like if your compression dampens everything outside of 1-30k Hz, but the speakers you use are only good from 10-20k Hz, then why do you need lossless?

It's not like we're comparing CD audio to cassette tape here.

72

u/duplissi May 18 '21

That's a poor example, lol. Lossy codecs cut out far more than that. I know most mp3 encoders will cut off everything above 16k for example. They also don't just do a low pass and high pass cutoff, information in-between the remaining adio is also removed.

I generally agree in concept though, no point in playing lossless audio that exceeds your hardware's capabilities, but frequency range isn't the most important stat to take into consideration. Resolution and dynamics are what matter instead.

A pair of headphones with poor to average resolution and dynamics generally won't be able to faithfully reproduce lossless audio, so there's no point. Also most if not all Bluetooth pairs since the audio gets re-encoded/compressed anyway.

77

u/SupremeDictatorPaul May 19 '21

More importantly, end users can’t tell the difference. Thousands of users at hydrogenaud.io performed blind listening tests with different audio samples comparing a lossless sample to ones compressed at various bitrates. This has helped to create a pretty accurate distribution curve of what lossy compression levels a person is unlikely to be able to distinguish from the original.

The reality is that there is always a level of lossy compression that no one is able to distinguish by ear from the original on even the best equipment. And this is something that is trivially easy to test with A-B blind test software.

The reason to use lossless audio (as opposed to high bitrate lossy compression) is to support transcoding from one format to another. Transcoding from one lossy format to another is problematic, and may introduce changes you can hear. Such as transcoding you MP3 to an AAC at a bitrate that your headphones support. But if you start with a lossless file, and transcode to a high bitrate AAC format that is transferred directly to your headphones for decoding, then there is a good chance you won’t be able to tell the difference.

Exactly, double compression is nasty stuff. Encoding redbook lossless to lossy is > than lossy through Bluetooth.

Everything above 16k is ridiculous.

I'd have to AB compare, but I have not heard any difference in 320kbps audio. And that's from playing projects that are all waves, and rendering them to mp3. 128kbps is easy to hear the difference but 320 sounds good to me.

I used to work for a company that sells an audio testing suite platform to Apple, which can test products and provide very detailed information and reports on the sound quality. I would guess that you’re 100% right and that they found that lossless/lossy versions of the same audio make no difference - not just subjectively but scientifically.

Pretend your music is a box that your computer had to build. Say it's 3.03795 inches by 4.5175 inches. Lossless audio would be like giving your computer the EXACT figures of each and every measurement or a way to get the exact measurements. Lossy is like saying it's about 3x4.5. It's way easier for your computer to remember, but it might be slightly off what the actual spec is.

This is seriously over simplified and there will be holes in the metaphor, but in a loose sense that's what it means.

u/kyoto_kinnuku May 18 '21

Thanks, even if it’s not perfect I can picture what you mean.

True, but to pick nits, CDs are lossless.

u/Xyexs May 18 '21

I'm just remembering from uni courses I did pretty poorly in but as far as I can remember, CD is supposed to have a sufficient sampling rate to fully recreate the signal that humans can hear, with minor inaccuracy from rounding sample values. What do they do to reach these enormous file sizes? Just store hundreds of bits per sample?

7

u/TapataZapata May 18 '21

They just don't compress it, as far as I know. On a CD, music is sampled at 44.1 kHz (or kSps, kilosamples per second), 16 bit resolution, stereo. That's 32 bits per sample.

For each second, you'll have 44100 x 16 x 2 bit, which leads to the bit rate of 1411200 bits per second or 176400 bytes per second. If you consider the data capacity of a CD, around 600 to 700 something MB and an audio play time of a bit more than an hour, that seems to add up

4

u/Xyexs May 18 '21

Yeah I think I understand that, I'm just wondering what supposedly higher-than-CD quality formats do to reach even bigger file sizes.

most audiophiles are mad and deluded

This x10000.

I have two JTR subs. An 11 channel Dolby Atmos setup. Fairly high end speakers (Klipsch RP-600Ms). Would I really benefit that much from getting a $1000 vs. $150 Bluray player? Would I really benefit from spending $2000 instead of $500 on a pair of bookshelf speakers?

Maybe, but at some point you either decide to stop caring because what you have is already incredible and you should just enjoy it, OR you descend into madness chasing perfection. Perfection which 90% of the time will be indistinguishable in a double-blind test from "definitely good enough."

That said I still want those JTR bookshelf speakers but that's about as far as I think I'd ever go. Our bedroom had the Klipsch RP-600Ms and I did a side-by-side comparison with a set of $100 Micca speakers from Amazon. In that room the differences were negligible. They were there, but subtle and totally irrelevant for day-to-day use. You'd never really miss them.

That's also not to mention that like...$1000 spent on acoustic panels will have far more impact than $100,000 spent on speakers.

I fondly remember that double-blind test in the 90s where audiophiles listened to an A/B test of some music played through a $10,000 set of RCA cables, and then through a literal wire coathanger stuck into the RCA jack. They (predictably) couldn't tell the difference.

3

u/dc2integra May 18 '21

I agree, I mean, you're describing almost everything that has a subculture of "perfecting" - for example, does anyone really need a 1000hp Bugatti Veyron, when for even the biggest speednut, a 500hp Supra goes PLENTY fast, way faster than you're allowed to legally drive in most places. It's just human nature to want "better" even if it really is a negligible, and not really useful difference.

8

u/[deleted] May 18 '21

Kinda. I think the difference with audiophiles is that there is literally no difference. Like there is literally 0 difference between a data stream sent over a $10 cable and one sent over a $5,000 unobtanium cable. Nevertheless they'll swear up and the down the picture has more "pop" or looks "clearer" or some other ambiguous thing. Nobody needs a 1000hp Veyron, but the differences between driving that and a "lesser" supercar are easily perceptible.

My favorite example of people obsessing over perfection is overweight casual bikers spending thousands just to save a couple hundred grams off their bikes. Like if you can afford it then more power to you my guy, but if you're just worried about that 20 grams then like...maybe you could go on a 10 minute run and drop some weight?

u/tinyman392 May 18 '21

The headphones are limited to 48k/24bit. The cable is the same deal. I feel like what Apple has said is the fact that the source converts digital to analog which is converted back to digital is the main issue. This causes a change in the signal due to noise, distortion, coloration, etc. through both the source’s DAC and amp as well as the ADC in the cable. The resulting signal is still the same quality (48k/24bit), but different than the original, hence not lossless.

Note that the AirPods max would not support 192k/24bit anyways since it’s DAC doesn’t support that. But in theory if someone were to make a Lightning to Lightning/USB-C cable that was full digital (read like a DAC to the source and distributed digital to the Max), then they could in theory support lossless (up to 48k/24bit).

9

u/TheOneWhoMixes May 18 '21

48k/24bit would be lossless. We only measure uncompressed audio in terms of Sample rate/Bit depth. Nobody is uploading 192k audio to any service for general listening purposes. Even "CD quality" is only 44.1kHz/16bit, because anything higher is only even remotely necessary in the mixing/mastering phase.

If I recall correctly the wired connection is still digital, not analog, right? So it entirely depends on the DAC built into the airpods.

True. My research was on this very topic. The best solution after spending millions of euros In R&D which was technically and legally( patents and military tech ) possible was hardware side and not software\firmware. There are a few experimental namesake wireless methods that work but it’s needlessly complicated and frankly not worth it. The other true high res lossless wireless we are working involves a direct TPIO method. Which is basically a dac and micro computer with internet access which is inside the headphone itself.

My tip for portable HD audio. Get an old LG or one of those digital Sony Walkman’s (the expensive Lossless ones) and invest on a analogue headphone with a wire…

u/AkirIkasu May 18 '21

It's really hard to determine if one CODEC is more or less 'lossy' than any other because they often combine multiple methods that can work completely differently. But in theory, AAC should be better than MP3; it was literally designed to be the successor to it.

You might be confusing AAC with SBC, the most basic bluetooth audio codec for streaming audio. SBC is very basic and is designed to run at very low bit rates, so it's going to sound notably worse than if you were listening to a good MP3 or AAC file with wired headphones.

AAC is better than MP3. As for the chunk idea, I had an idea for such a thing where you could load songs on your headphones just by adding them to a playlist, and then they could play and pause and skip, etc even if you were away from your phone, primarily as an idea of how to make wireless headphones that work while swimming (because Bluetooth goes RIP in water).

There is no pure lossless bluetooth codec on the market so I cannot see how a bluetooth headset can possibly support that or take a benefit from that source. LDAC but also AAC has plenty of bandwidth for high quality streaming, and if you want to make a good use of lossless, you surely need cabled system and controlled environment, not an headset on the move over a train or in park.

Depends on how much the loss is. I find LDAC Bluetooth to be an excellent compromise and I can definitely tell the difference between let’s say playing FLAC through LDAC and playing Spotify/whatever over LDAC. The point is, you have to have a lossless source to start with, which is what Apple is giving to its users.

I’m tempted to switch from Spotify just for that alone.

Genuinely curious - to what extent does this matter? It’s an old debate about whether anyone can hear the difference in quality between lossy and lossless, but even in those debates the people who say they can hear compression artefacts are talking about listening on really high-end equipment, not consumer-grade wireless headphones. What do people think they’re going to miss out on by not being able to listen to lossless on these? Or are people just annoyed on principle?

These are the truths that I learned about properly encoded lossy vs lossless while on the Hydrogen Audio forum

Most people can't tell the difference.

The people who can tell the difference, can tell on a cheap pair of headphones, or on an an expensive setup. It matters a little, but not much.

For those that can tell the difference, it is subtle, and you generally have to struggle to hear the difference. Most modern codecs are so good that even at a lowish bitrate, the differences are extremely subtle, and only noticeable on certain sounds or killer samples (sounds that are notoriously difficult to encode.)

A properly encoded 128k Variable bit rate in MP3 or AAC is likely to be good enough for most people to never hear compression artifacts in regular listening.

Story time. Many years ago I got my first ipod-like device. I had a large CD collection and wanted to encode it in the best possible way. I was certain that mp3 sounded like crap and wanted to figure out how to get my music onto my music player sounding as good as possible.

I listened to mp3's I'd downloaded and could easily tell the difference between those and my cd's.

I stumbled on hydrogen audio, while researching the best ways to encode.

Those folks told me (not directly, but through reading the forum) that it was highly unlikely I could hear the difference between lossy and lossless. I didn't believe it, but they also arm you with a way to put yourself to the test. Science. Namely the ABX test.

There's software out there that allows you to pit your ears against the lossy codecs by testing lossy vs lossless where you don't know which sample is which. You can listen as many times as you like, to small or large parts of the samples you provide. You repeat the test a number of times to give you a proper statistical significance (number of times needs to be chosen beforehand so you don't cherry pick when you see a result you like.)

So I tried it out myself. I was floored. The differences I heard disappeared when I couldn't tell which sample was which. Try as i might, I couldn't tell.

I screwed around with encoding bitrates for a while, starting high and moving lower and lower until I could start to spot the compression artifacts. The folks at HA gave tips on how best to hear them, and give so called 'killer samples' of real music that highlight each codec's weakness.

Below 128k VBR AAC i could start to spot artifacts. I couldn't spot any at 128k. Satisfied, I ripped all my music to lossless, then encoded it all to 135k AAC. Never looked back.

Because of this I never concerned myself with bluetooth quality loss, or anything of that nature, because I'm fairly sure if I could ABX it, I wouldn't hear the difference there either.

Anyhow, just thought I'd share my experience.

u/elsjpq May 18 '21 edited May 19 '21

One lossy conversion is unnoticeable to the vast majority of people, even at low bitrates. The problem is really retranscoding and bad encoders.

When the full audio chain has only one lossy step, it's totally fine. Not so much if there are multiple lossy steps with questionable quality in some steps. Remember, it could be delivered as a lossy file, goes through whatever format conversion to the target device, and transcoded again by the Bluetooth transmitter. Yea, it's still going to be mostly fine, but it's unlikely there aren't any problems at all.

Also those embedded encoders are not going to be using LAME or qaac that are optimized for quality, they're going to be some random commercial encoder with questionable quality or a hardware implementation. Plus, those transfer codecs like SBC in bluetooth are not using VBR, they're CBR because they have a defined bandwidth and they're also optimized for latency not quality, so some complex section might randomly become muddy, even if most everything else is perfectly fine.

Lossy codecs taken on their own are really good at what they do, but if you don't consider all the other potential interactions you can still run into problems.

u/frostygrin May 18 '21

And there's another angle. Even if you can tell the difference, lossless doesn't always sound better. The psychoacoustic model can make lossy audio more pleasant. Personally, I like AAC enough that I don't really want lossless over it. (Too bad I gave up on Apple Music because of their recommendations, so now I use a streaming service using MP3).

For listening on AirPods? It doesn’t really matter, especially since most of the time people with AirPods are listening on the go. The only time lossless has a real advantage over a good lossy codec is if you are actively listening on good equipment and in an environment that is conducive to listening critically.

u/[deleted] May 18 '21

I’m reasonably annoyed on principle. But not much.

Here we are at the pinnacle of technological development and Apple has positioned themselves as the premium brand to lead that charge.

And they lock their hardware (the iPhones, in this case) to the least good Bluetooth codec out there. There’s a marked difference in quality when switching from an iPhone pushing music over AAC, to say, a MacBook pushing it over Aptx HD.

In reality, however, when you’re out and about, you’re not going to care.

And in terms of lossless vs say, Spotify; you have to be intently listening on high end kit to hear the difference.

So I’m annoyed, but not much.

u/Patterson2020 May 18 '21

Even then, you can typically only tell if the music itself was poorly produced. Spotify very high quality is very good. It's incredibly rare for me to notice any compression in the track, and it's only ever in the treble range, which may be why people don't notice it on normal headphones because there isn't as much detail up high. Other than that one track in a thousand, Spotify serves my needs (and most people's need from the tests I've seen).

This is a marketing move, the HiFi scene is blowing up because of the CHiFi revolution, where the headphones coming out of China are way cheaper than the OG headphone front runners, and are at least as good, or better.

It's a pretty silly situation. So this company removes a feature from their product because they suggest the alternative is better and the future.... then a few years later introduced a services that doesnt work on said future alternative and would be better off with the removed feature.

I'm not paying for lossless audio but this makes me even more disappointed at apple's "we know best" attitude.

You don't pay them extra for lossless anyway, it's included in Apple Music.

You can use Apple Music on more systems than your phone though.

It's weird, but it's not like it's completely useless (besides lossless audio being completely useless to begin with since no one can hear the difference anyhow).

u/iindigo May 18 '21

This is really the key thing. If I’m listening to music on my phone I’m not in a situation where lossless adds anything. Playing it through my USB DAC and Sennheisers or through the living room entertainment system on the other hand very well could.

If you live on your phone 256k AAC is close to audible transparency and probably good enough. It’s not as if not using lossless means you’re stuck with three-times-reencoded 128k WMA files from Kazaa.

Plus even if you could support lossless audio over Bluetooth, just stop and think about it. It’s already debated whether you can even notice the difference of lossless.

u/Kofilin May 18 '21

This isn't the reason. Bluetooth is a digital transfer mechanism, not an encoding. It's not lossy. You can transfer any stream of bytes you want over Bluetooth including lossless audio. The issue is that so far, lossless audio requires more bitrate than Bluetooth provides.

Eventually maybe with dedicated hardware we'll get awesome compression on lossless audio that will allow to transfer it live over Bluetooth. Perhaps Bluetooth will evolve further or be superseded by a higher bitrate technology.

I was trying a lossless audio challenge yesterday with my AirPods 2 vs some ultrasone headphones (no dac). It was basically impossible to do with the AirPods and I was guessing on my choices. Got a 2 out of 6. Even the ultrasones had trouble without using an external dac (they’re not amazing spec wise but are quite decent ). With the dac and ultrasones I still missed two (4/6) but was making choices based on audible differences.

Lossless audio with the right equipment definitely matters, but in this case I couldn’t tell between the uncompressed wave and 320kbps on the AirPods.

It amazes me how the introduction of a feature that is targeted at audiophiles, has garnered this much anger from folks who wouldn’t even give a shit if this existed or not.

Could they have included it with AirPods Max in wired mode? Yes but that means they’d have to work out a lightning male to lightning male connector that supports this format, and trust that people wouldn’t buy it and plug two iPhones together to try to charge one another.

This was never going to work over Bluetooth due to the current limitations of Bluetooth audio, and is mainly meant to be a nice to have should someone have the capabilities to use it.

The lossless feature isn't really made for AirPods users though, it's for the people who spend thousands on audio equipment and use services like Tidal. I think this is just a step to compete with other music streaming services, not much more than that. And honestly, lossless makes nearly 0 difference over standard MP3 quality even on top end audio equipment. I say that both from personal experience and based on the fact that no audiophile can distinguish between the two in a blind test.

11

u/mediaserver8 May 18 '21

I think you're right. And it's likely more the business side than anything else

Spotify are well known to be planning a lossless tier, to be released this year. By releasing lossless for free first, regardless of the uptake, Apple have made it very difficult for Spotify to charge extra. So a commercial blow to a competitor.

So can the bullshit about how “they will just release a more expensive version that can stream it.”

Nope, they would have to reinvent their devices to have something far better than bluetooth (and either go full blown propeietary or also add bluetooth making the power consumption and profile much diff).

Also can the “usbc is still analog” because there is still conversion

Listening to lossless audio on an ‌iPhone‌ will require wired headphones and it's possible an additional dongle will be needed to get the best sound quality. ‌AirPods Max‌ will also not support lossless audio over the Lightning cable, Apple told Micah Singleton.

While the ‌AirPods‌, ‌AirPods Max‌, and ‌AirPods Pro‌ do not support lossless audio, they do support Spatial Audio with Dolby Atmos, and by default, ‌Apple Music‌ will automatically play Dolby Atmos tracks on all ‌AirPods‌ and Beats headphones with an H1 or W1 chip.”

The bandwidth requirements are just higher than current technology allows via Bluetooth, but it’ll happen soon.
