New "mp3PRO" From Fraunhofer, But What About LAME?

xenoweeno writes: "This Week In Consumer Electronic reports that Thomson and the Fraunhofer Institute are working on a new mp3 format they've dubbed "mp3PRO."

    I think you are making a wild assumption. What I think you dont realize is you are using your 'capitalist-centric' rationale to relate these things unnecessarily. Its a chicken-egg problem. I believe that because the modern social organization is essentially the corporation it plays a dominant role in everything. While I'll agree that new tech usually appears under a Corporate moniker - it does not happen as a natural result of something this corporation provides.

    Research is done by people -- these people have motivations (fame, food, sex, whatever) -- if they were _allowed_ to produce work for the public domain: they would. The technology would still be there -- there would still be innovation. We have allowed corporations (or those who can use them as tools to satisfy their own needs) to gain _alot_ of 'power'. That power is all around you - your City Hall is a corporate entity and acts like one, your employer is a corporate entity and acts like one, your civil groups, your soccer league, your grocer -- EVERYTHING is a corporate entity and acts like one.

    What I would advocate is a legislative restructuring and balancing of (Capitalist) Corporate vs Civic vs Private 'power'. We have (unfortunately) allowed (Capitalist) Corporate entities to 're-organize' culture to their advantage -- I use the analogy of a virus being capable of altering conditions within its host -- this effectively precludes any action outside of this dominant social structure.

    So, back to your original point: Don't believe that innovation, freedom, basic needs and all else that you require for sustenance would vanish if Corporations did - that somehow they have 'given' us these things: It is very untrue. Technology would be born and evolve quite well outside of the present (Capitalist) Corporate world - maybe more so, because alot of the unfortunate after effects would be lost -- we could spend a greater amount of our efforts on worthwhile things (technology, art, and other self-satisfying pursuits) if we could abandon the 'necessary evils' of the corporate world: Advertising, Marketing, BizHeadTalk, Consumerism, Needless Pollution, Self Rewarding Greed, Corporate Enslavement, Exploitation of the Underprivileged and other various crap - people should be able to live their lives without being _forced_ to participate in (in what I believe) to be a selfish, ill-conceived system to fuck other people. I believe it is better to share with your neighbour than to steal from him - but what option do I have outside of being a modern-life-martyr and starving?

    Compression is not the same as filtering. True, CD audio has its own artifacts because of the brick-wall filter necessary for the 22KHz cutoff and the 16-bit sample rate. 24-bit sampling takes care of the artifacts for most carbon-based life forms, and with a 96KHz sample rate, the Nyquist theorem tells us that our nasty ass brick wall filter works in ranges exceeding 40KHz, well out of the range of humans. Still, according to your definition 24/96 is still "compressed" because we're still discarding some data. Well, then every single bit of data in the world is compressed, because we would need infinite sample rates and infinite resolution to get "everything". We'd also need pure omnidirectional microphones with infinite frequency response and infinite sensitivity.

    Let's not be silly and just say that a compressed format uses a compression algorithm, okay? And there is a difference between lossy and lossless compression.

      It's getting into semantics now but in the contexct of his argument, his description of lossy compression is correct.

      The art of lossy compression is to remove parts of the data that won't be noticed. In the case of TV for example, advantage is taken of persistance of vision and the angular resolution of the eye to say "We can usually get away with 50-60fps and a screen that contains *about* 640x480 pixels). With mp3s, advantage is taken of certain harmonics of tones being inaudible to remove the need to encode them.

      You say that a compressed format needs a compression algorithm but the TV algorithm is "sample the picture every 1/60th of a second and average light values over x degrees horizonatally and vertically, arrange the samples horizontally and vertically and add sync pulses as appropriate". That *is* an algorithm

      Now, you may want to argue that for compression, the algorithm has to be complex and change dynamically with the data but then we *are* getting into semantics and I think you're choosing to define your terms to support your argument.

      So I agree with the original poster, all data fed to us us compressed in some way. Usually, effort is made to ensure that the losses are not noticed by us (with mp3 as much as with TV). Some audiophiles claim with mp3 that this is not done successfully (though I can't tell. I have "fill in" with music where I'm listening to the *music*, not the waveform that's coming into my ears). But equally, with TV, there's room for improvement (digital TV, HDTV et al).

    Sorry you got such stupid responses from others on this question. Here's a better one: Yes, it does mean you get better quality.

    To use Microsoft's Windows Media Audio format as an example (because they make the same claim as MP3PRO): One of Microsoft's claims on WMA is that you get better quality at half the size. This is actually more true than most people (especially around here) are willing to believe. I thought it was marketing BS until last week, when I decided to run an informal experiment.

    Using MusicMatch Jukebox I ripped one song ("Finding Me" by Vertical Horizon, because it starts off immediately with sufficiently dynamic sound) into raw WAV, 128 and 64 kbps MP3 and 128 and 64 kbps WMA. Then I listened to sections of the song, comparing the same section in the five formats. I'm a vocal musician, and have a sensitive ear to sound quality, particularly in music (I know it's not as rigorous as that waveform analysis of MP3 encoders that was published here recently, but in the end it's how the music sounds to the human ear that really counts).

    I was impressed with the fidelity of the 128 kbps WMA. In fact (and I was quite surprised at this one) the WMA was truer to the original than the same bitrate MP3. The MP3 was actually slightly dampened in the high ranges compared to the original. What was really surprising were the 64 kbps files. The MP3 at that bitrate basically sucked, because the sample rate was only 22 kHz (resulting in weak low ranges and muted upper tones), while the 64 kbps file sounded quite good, because it was still at a 44 kHz sample rate. Of course, there was a slight degradation (to my hearing) in the sound quality between the 128 and 64 kbps files (mainly a slightly "metallic" sound in some spots), but I suspect that most people wouldn't really notice it.

    So, MS's claim of 1/2 the size, better quality is not strictly true in combination; it's more like same size == better quality, half the size == considerably-more-acceptable-than-MP3 quality at that size.

    If MP3PRO uses an even better compression/interpolation algorithm than MS Research came up with for WMA, then not only will 128 kbps MP3s sound better, but 64 kbps MP3s will probably start becoming the norm for use in pocket MP3 players.

  7. mp3pro doesn't have mastering controls by Chris+Johnson · · Score: 3
    mp3pro doesn't have mastering controls to match LAME. LAME has a control based on ATH level that I call 'ambience suppression level', and if you know what you're doing and can handle the HF and LF rolloffs artistically you can get _much_ more of the essence of the sound encoded than with Frauhofer encoders, including a far superior 'take' on the reverberant field that is not totally collapsed and obliterated, while still keeping it in balance with foreground sounds.

    Why do I say this when it's not in the LAME docs? Because LAME is open source, I needed it, and I hacked it in.

    It's that simple. (I've tried to interest the coders in this but they don't 'get it': I think mastering engineers will be a lot more interested.) Let me put it this way- as long as there are mastering engineers and studio types willing to struggle with the code enough to look after _their_ interests, LAME will beat whatever Fraunhofer comes up with, because Fraunhofer is all computer geek researchers- I see them going for a 'one size fits all' consumer encoder, and this is totally unacceptable and wrong for professional use.

    And encoding music into mp3 or similar lossy formats _is_ a professional task: in the field of music it is so competitive that anything a band or artist can do to give themselves an edge _will_ be done. If LAME operated by a real mastering engineer using serious reference speakers and adjusted to let the soul of the song through beats the quality level of mp3pro operated by the artist... then the guy using LAME will score more downloads, get more attention and money, sell more CDs when his music _sounds_ _better_ at the same bitrate, and the guy using mp3pro and coloring his sound with a preset compressor that isn't tailored for the individual song will _lose_.

    This is such an obvious development, and it is totally favoring the 'open source' side of things, because there are not enough 'mastering engineers', even wannabes, to tailor a commercial product to them- yet the work they do can outperform what you'll get from preset compressors. It's not the easiest skill to acquire but if you can do serious mastering on CDs you have the skillset to know what to do when you have your dirty little hands deep in the internals of LAME.

    I'll demonstrate using my music as an example: the top album, "Marginal Theorems", and the second most recent, "Wounded Skies", are all made into mp3s using LAME with this ATH level control and extensive mastering work on the low and high frequency cutoffs. Psy model is turned off and replaced with ATH masking only, and ATH is custom set to the needs of the track to render the reverberant field with the proper weight, where necessary. The high cutoff is a great deal more gentle than you'll usually see, so that the tendency of the encoder to grab at all the HF data it can get is mollified without seriously altering the tonal balance of the HF sounds- basically the highs are eased back in volume until they take a place in the soundstage that isn't over-forward, but retain their character. The lows are set with a combination of low cutoff and slope that allows a sort of resonant area to be moved up and down according to the needs of the track- sometimes extending well below hearing, sometimes moved up to add muscle to the midbass.

    Go ahead and hear for yourself. You should hear how good the _256K_ mp3s from the same settings sounded! (I'm probably going to find a site that lets me upload those for high quality buffs or those who want a CD made- probably Ampcast.com.) Any mastering engineer could do this, but at the moment it is LAME-only because I'm not aware of any other encoder that lets you meddle with the guts of the encoding parameters that way. I asked about this for almost a year now and nobody had an answer, so I finally did it myself.

    Anyone wishing to roll this into the main LAME distribution will get full cooperation from me... so far I haven't seen an interest. Which, cynically, I don't mind so much: _I_ believe in the principle of free software, but if people don't _want_ the hack by which I'm able to encode ambient information properly, fine: I'll just use it myself. I happen to think it is one hell of a secret weapon. I posted on rec.audio.pro about my modified Lexicon reverb and used 'Marginal Theorems' (128K mp3) as a demo of what I do with my Lexi and people were _floored_. They didn't neccesarily figure out how much of that I owed to free software and LAME, though ;)

    So MP3 comes out, and open source can faithfully reproduce it by violating these (non-obvious) patents. It matches implementation but certainly doesn't improve on the efforts of Fraunhofer institute, their real work being in developing the acoustic model. If Fraunhofer can improve on that it just shows that potential for improvement was always there, but open source efforts weren't good enough to find it.

    The only reason people would switch to this new encoding would be if it was substantially better. If that means that open source software falls behind - tough shit, this can be fixed eventually, it just means ignoring a different set of patents. This just shows where the real innovation comes from. I know that innovation is a dirty word now that MS have got their fangs in it, but there is such a thing as the genuine article.

To create/use an encoder, the law says one must pay royalties to Fraunhofer and other MPEG Consortium members.
