Are iTMS's 128kbps Songs Worth Collecting?

pinchhazard writes "Randall Stross of the New York Times offers his opinion on iTunes Music Store's decision to offer downloads at only 128 kbps, and that decision's potential to affect collectibility of the songs. The article says that Apple makes the claim on its web site that "you'll get the full quality of uncompressed CD audio using about half the storage space." Rhapsody, which offers encoding at 192 kbps, is compared."

    (although I'm unsure what Rhapsody uses, maybe it uses MP3Pro which is pretty good).

    I think that 128kbps is a little shortsighted from Apple, there will be losses in the audio at that rate. 192 kbps AAC would be preferable of course.

    Then again, most people listen to music on cheap headphones, speakers, etc, or just want music in the background. In that respect 128 kbps AAC is way more than necessary, and beats a cheap FM radio totally (if only in that you don't have a retard DJ wittering on between tracks).

    Music is just part of life these days.

      It's also important to note that Apple's AAC files are encoded at 48khz (from the original DAT tapes, in many cases) instead of the normal 44.1khz cd-mix, which potentially significantly improves the quality. In some rare cases it might even produce something that's "better" than cd-quality.

      Yes, it's still a tradeoff, but going from the original DATs means no frequency aliasing, which is a Good Thing.

      A few points:

      1. The Nyquist Theorem states the maximum possible encoded frequency in a digitized waveform. It says nothing about how the waveform may or may not suffer aliasing as the frequency approaches half the sample rate. I.e. a rate of 44.1khz is necessary (but may not be sufficient) to encode a 22.05khz tone. I'm not sure this was clear in your reply.

      2. "Human ears listen up to about 16kHz." Leaving aside the variance between ears (which is huge- some can hear above 20khz), nigh-subconscious overtones depend on these frequencies. Even if you can't hear these high frequencies alone very well, they do (measurably, and meaningfully) add something to music. Just crop everything above 16khz on a song and listen critically.

      3. "A CD delivers audio at 1411.2kbps. The CD audio format was created to conform to what is the best that human ears need." Yes, based on 1980s research. We've come a long way in audio theory, though. Also, all bits are not created equal- I guarantee you that a DVD-A stream compressed into 1411.2kbps would sound better than a CD.

      I think my points still stand.

  2. For many people, they cannot tell the difference. by karmatic · · Score: 5, Interesting

    I've ran a number of informal listening tests, and many of the people I tested cannot tell the difference between a 128kbps MP3 (LAME) and a 256kbps MP3 (LAME) consistently, even on good equipment. (Too much loud music as a teenager, perhaps)?

    This article is full of so many distortions, it's mind-bending. First, they are revealing the secret -- which they assume none of us gullible rubes ever realized before -- that most digital music we get from the internet is stored with lossy compression. The article goes on to explain that all music with lossy compression sounds crummy (comparing it with 8-track tapes), and the only measure of digital sound quality that matters is the bit-rate.

    Music from the iTunes Store, they say, sounds extra-crummy since it's compressed to only 128 kbps. (The distinction between AAC and MP3 is never even mentioned.) The implication is that consumers will rebel someday when they discover they've bought a bunch of music that isn't "true CD quality". Clutching torches and pitchforks, they'll storm the ramparts at Cupertino.

    Maybe I'm just a tin-eared old goat, but the difference between a CD and a 128 kbps MP3 track doesn't leap out at me in casual listening. When it comes to 128 kbps AAC or 192 kbps MP3 tracks, they sound like CDs to me -- even when I listen closely, with headphones. Maybe if I had audiophile speakers or better headphones (or younger ears) it would make more difference, but honestly. . . This is not a distinction that keeps me up laying awake at night, wondering if my music collection is subtly flawed.

    At the other extreme, the true golden-eared stereophiles of our world have complained since CDs first appeared about *their* low sampling rate. What, only 44,000 samples per second? You can't capture sonic detail at the high frequencies that way! But given the difference in sales between iPods on the one hand, and SACD or DVD-Audio players on the other hand, I think anyone can see which way the wind is blowing.

If the bit-rate were the only difference to him, the article would have been much shorter.

    He refers to comments from Sterophile twice to bash Apple - but never Rhapsody - and refers to 128kbps as "the low end of the bit rate range", clearly unaware that smaller MP3 players compress music down to 96 or 64kbps. He refers to an "apples to Apple" comparison of 192 to 128kbps, saying, "the companies use the same software standard for compression" when, in fact, they don't.

  11. Frequency Myths! by Venner · · Score: 5, Interesting
    Human ears listen up to about 16kHz.

    Maybe for older folks whose hearing has degraded somewhat. People usually cite an upper limit of around 20kHz. I can certainly hear a tone at 20kHz, from a good tone generator (not a cheap one with harmonic interference.) That alone puts the Nyquist rate at 40kHz.

    What's more, although people may not consciously perceive higher frequencies, work has shown that people do subconsciously perceive them.

    To quote (from the article I'm linking):
    Oohashi and his colleagues recorded gamelan to a bandwidth of 60 kHz, and played back the recording to listeners through a speaker system with an extra tweeter for the range above 26 kHz. This tweeter was driven by its own amplifier, and the 26 kHz electronic crossover before the amplifier used steep filters. The experimenters found that the listeners' EEGs and their subjective ratings of the sound quality were affected by whether this "ultra-tweeter" was on or off, even though the listeners explicitly denied that the reproduced sound was affected by the ultra-tweeter, and also denied, when presented with the ultrasonics alone, that any sound at all was being played.

    The author also notes such facts as that 40% of a set of cymbal's audio energy is above 20kHz. So a 96kHz audio recording (range=48kHz) is not unreasonable. But good luck finding equipment to really play it back on correctly :-)

    Well, let's see. I used to listen to albums, that were apparently far superior in sound quality than anything else in the world. They would get scratches that would cause them to make popping sounds and would add fuzz to the music. What the hell, it still sounds fine.

    Next, I bought cassettes. Cassettes had an always present hiss in the background and after several plays, the music on the cheaply made cassettes would start to fade. What's worse, the tapes would eventually stretch and snap after overuse. That was fine too. I could listen to my music.

    Then I bought CDs. These were okay too. They were bulkier than cassettes--sort of. They were also prone to scratches, but far less so than records. The problem was that they were digital and not analog, which meant that I wasn't getting to hear all the sound that was being played by the artists (as we obviously were with LPs and cassettes since they had infinite information storage capabilities). Oh dear. Where's my tape hiss? Where's the fullness of my phonograph? Well, whatever. I can still hear the music.

    Now I have lossless MP3s and AACs. The horror. They don't scratch. They don't add tape hiss. They don't wear out at all and are incredibly portable. However, they don't store all the information that our CDs do. They even distort some of that sound. Oh no! Oh, wait, I can still hear the music. That's okay.

    So, my point is, what the hell does it matter? There's no perfect recording medium. If there were no choices we'd be happy with whatever we had. Now that the common consumer has a choice, she frets day and night over how many bits she's losing. Talk about a waste of time. Freedom of choice isn't always a blessing. It can distract you from those other freedoms that are slipping away.

    This IS the case. What the article and few people on /. have failed to mention is that the problem is more a matter of the output quality of the iPod than the bit rate of the compression.

    When I got my iPod, I was hoping to replace my CD player by hooking it up to my receiver. This was trivial to do technically, but the sound quality was always poor. I experimented with many, many different sampling schemes (i.e., AAC and mp3 at various bit rates). I finally settled on AAC at 224 kbps, but the output from my iPod was still inferior to what I got from CDs. Then, one day I plugged in my Powerbook to my receiver via the exact same cables that I use to connect my iPod to my receiver. Low and behold, the sounds coming out were PERFECT. (FWIW, I have a Harmon/Kardan receiver with JBL speakers. Good shit.) That's when I realized that the iPod was not designed to be connected to high fidelity equipment. It's output was designed for earphones.

    So, I complained and complained to Apple, and sure enough, one of the improvements in the last iPod update was "improved playback." And, I heard the difference as soon as I installed the update. It's still not quite hi-fi, but it makes my trips in my car much more pleasant. At home, I still use either CDs or my Powerbook, but I think complaining some more will get more results from Apple.

    I have complained to Apple about the bitrate, also, but for $0.99, one does get a good bargain.

Then you demonstrate your extreme ignorance of the very process you try to sound knowledgeable about by implying that all 256 kbps compression does is filter frequencies above 20Khz. This is wrong. Completely wrong. Not even close to how it works.

    Your assertions about what people can hear or not hear are just that: assertions. It's totally meaningless. Just because audiophiles have not bothered to produce some kind of test to your satisfaction that proves beyond any doubt whatsoever that they can hear the difference does not mean that they cannot hear the difference.

    I have done so called abx testing of my own using the software from hydrogenaudio, and I was not only able to correctly distinguish which tracks were compressed, but also which tracks were encoded with which codec (although not as accurately).

    I am confident that I could personally pass any legitimate test you could come up with comparing 256 kbps material with the CDs. I will admit that 320 kbps would be more difficult, but given a sufficient amount of time and high enough quality source material, I could blindly identify those as well. So much for your 320 kbps is lossless theory.

    There is one codec that I am not completely confident I can identify though: MPC. At a high vbr this codec tends to sound really good, even to me. The author of that proggy really did his homework when it came to psycho-acoustic compression. I haven't done a lot of testing with it. Maybe it really is transparent. I don't know.

    I am poor and I can assure you that I do not buy CDs out of the goodness of my heart or because I feel sorry for the rich record company executives and "artists". I buy CDs because I can hear a very significant (varies based on source quality and bitrate) difference.
