Statistically Optimal Music 296

Posted by michael from the pop-rock dept.
ShinyPlasticBag writes "'Eigenradio makes its optimal music by analyzing in real time dozens of radio stations at once. When our bank of computers has heard enough music, it will go to work on making more just like it. Since we listen to so much music all the time, Eigenradio is always on and always live. What you hear on Eigenradio is the best of the New Music, distilled and de-correlated. One song on Eigenradio is worth at least twenty songs on old radio.' Listen up here or here (SHOUTcast)."

    I quickly checked out the site and hit the #1 "Listen" link. At first, it was an interesting mix... in fact, it sounded very much like tuning an AM radio between stations, except that the overlapping songs were in clearly-defined hi-fi.

    It was jarring at first, but then I got into a groove. They're right, the beat and the ambient voices have a strange but familiar variance.

    Unfortunately, I don't think I'll be able to keep up the experience. After about a minute, the rhythms stopped, replaced by a metallic, toneless hum.

    Cool... I've seen the Slashdot effect before, but now I'm getting to hear it!

    Footnote: the rhythm has returned, but there's a lot more buzz than before. Will be interesting to hear what happens when the non-subscriber flood hits.

      What makes you think that the slashdot effect changes the content of the music?

      I heard the same thing that you did, but as I understand it, the only input that goes into the music is the content of the radio stations to which the server is listening. I don't see how the number of listeners to eigenradio would have cause the effect you're describing.

        What makes you think that the slashdot effect changes the content of the music?

        I guess it would depend on how they've configured their systems. If they have one box processing the incoming signals, and another box uploading the result to their Windows Media Server, then we might overload the second box but the sound would be unchanged.

        But if the box that does the processing is the same as the one that's attempting to service all the requests from Slashdotters, it seems like it would eat up CPU cycles. That would make it more difficult to do the real-time synthesis of 20 incoming signals. I suspect that's the cause of the toneless drone I was hearing.

        Add to that the bandwidth -- do they have one pipe that's receiving 20 signals, outputting (however many) Eigenradio streams, *and* serving up the strangely-formatted web page?
        • I don't know, but recieving the signals isn't the problem, they're being pulled out of the FM spectrum. 20 radio stations. You're probably onto something with the CPU usage tho. Interesting...
        • So you're assuming that there's only a few seconds between when eigenradio "hears" something and when that sound gets used in eigenradio's own composition. My guess would be that there is actually a longer lag in between these two events.

      IMHO this is yet another example of how academic projects are judged by the amount of attention they attract, rather than on whether they advance the state of the art.

      Every Spring semester at Michigan State University's Computer Science department, the capstone class (taken by seniors to graduate) did a project and had a "poster competition" to see who did the best project.

      The team that won the year I saw them was the team that wrote a program that graphed a song's FFT over time. That's it. They went on to babble about how you can recognize a song based on how it looks, visual recognition, and it did some ill-conceived 3D stuff that, by making the song data fit into even less space on the screen, was even more impossible to see. (I think you were supposed to eventually pick the song you wanted to hear by looking at this tiny, tiny representations.... at the risk of potentially offending one of the authors, who may conceivably read this, that's stupid! If they just seriously tried it once, they'd have seen how poorly this worked.) (See here [tp.spt.fi] for an example of a guy playing around with that kind of graph; note most songs look NOTHING like that in an FFT graph. ;-) )

      The fact is, it's a neat idea but it doesn't work. All songs in a particular pretty much look alike in an FFT graph. The differences are pretty minimal. Making it smaller doesn't help at all. The program looked really cool on a poster, using one song, but use it on six or seven real songs and ask even yourself to distinguish them and you can't; you don't "see" and "hear" that way.

      IIRC a dot-com was founded based on this idea, AFAIK indepedently derived.

      What does this have to do with your post? I thought about half of the other posters deserved the prize over this project, in that they were useful, interesting, or potentially even groundbreaking, in the small way that a semester project can be. But they didn't have a Beatles song graphed out on their poster. They lose.

      Even college professors aren't immune to judging on surface appearences and glitz, rather then real value.

      Eigen is a fairly well-established prefix in quantum mechanics (eigenvalues, eigenvectors, eigenstates etc.) An eigenstate is one of an infinite set of orthogonal solutions to a set of equations, an eigenvalue is a unique value (often energy) corresponding to a particular eigenstate. Thus I suspect in this case the term is supposed to mean something like "unique radio", which seems at least reasonably appropriate, if rather skewed. I suspect you're wrong about it being a comment on the state of the music industry, at least primarily. It seems like they're just using radio stations as a source of material 'cos it happens to be readily available.

        "Eigen" in german means "essence of", "characteristic", "similar" etc. The term comes from linear algebra, not quantum mechanics. If x is a vector and A is an operator, and A x (A applied to x) has the same direction as x, then x is an eigenvector of A. For example, if the operation is "reflect in the xy plane", then any vector parallel to the z-axis is an eigenvector of the operator. The scalar that x gets scaled by is called its eigenvalue. For the reflection operator, -1 is the eigenvalue for any eigenvector. QM extended this concept to other objects like states.

        So the term eigenmusic could be used to describe the underlying defining characteristic of a music. You could say that all Britney Spears' music has the same eigenmusic.

    ... that this site is a wonderfully clever troll? Once you get past the notion that anyone could possibly be serious about Eigenmusic, satire is all that makes sense. A tip of the hat to the creators!
  • It would be interesting to hear the differences in "statistically optimal" music produced as a result of correlating different genres of music.

    E.g., would people who only listened to Rock be more inclined to like the output of this program if its input was limited to Rock music? Could it create an "optimal" song?

    What you hear on Eigenradio is the best of the New Music, distilled and de-correlated.
    One important thing I learned in my statistics classes was "Garbage In, Garbage Out", essentially that any system which is fed garbage will produce garbage as its result... Given that most new music is garbage, won't this merely produce garbage as its output?
  • Taking all this, mixing it together in a big bowl, does not make something resembling the components, or even anything very appealing.

    Well, neither does this.

    I think from the dead webserver they are now playing a very literal version of Simon and Garfunkel's The Sounds of Silence - because I can't hear a damn thing!
  • I find this drive for computer generated artificial music unnecessary. Why bother, when we have airwaves full of _equally_ uninspired, artifical music such as Justin Timberlake and Christina Aguilera.

    Besides, it seems like this process of Musical distillation, of which the story speaks, has brought us these "talents" in the first place!

    I'm slightly scared. This is a technological curiosity of its own might, granted, but this prompts me to envision a rather gloom future. Originally I've thought that the rise of networking would eliminate the entire corporate structure involved in music-making and be replaced with system where everyone can give a go at composing, publish their work online and where the best artists could probably managed to make quite a fortune with voluntary donations.

    However, could record companies do the ultimate thing, a la Nineteen Eighty-Four, and create a computer program that produces the music most of us want to hear? Would that mean the end of human creativity on that level of play, or would this algorithm be doomed to failure? It might only take a few years to adjust, and you'd end up liking it.

    Of course, a prudent question is, if music can be replicated so easily, what's the point in appreaciating it any longer, as it's clearly something even machines can do well...

    Next up: television series writing machines. But, oh wait, we already have reality tv...

    • Computers writing music will never happen. At some level, it will always be people using computers as tools to write music. But we have that already (ie Mixing of music).

    So if you listen to modern Turkish in 7/4 and a 4 beat rock. Though in a little Jamaica and you will get Garth Brooks? Whenever you try to quantify music to find the ultimate groove you will get the ultimate in mediocre shlock. I once really tried to listen to an ultra post modern new music concert. The host stated that the music was written in a post modern a-tonal non serial fashion and was a-rythmic generated chance. The composer had then orchestrated some of the results. After really giving the music full attention and every chance to do something for me, I came to the conclusion that the result was decidedly A MUSICAL. I also came to the conclusion that the school of music that this composer was associated with was filled with air heads behind desks that most likely gave up actually playing real musical instruments after graduating from where ever. The musicians in the Orchestra gave it their best shot, which was rather sad. The applause was perfunctory so the lack of an encore was very much appreciated. If the composer/conductor had prepared one it will just have to wait.

    Statistical analysis is just not the way to write music, except perhaps for tone deaf nerds, and record execs. You have every right to play whatever form of music you choose. I have every right to listen to something else! If it got groove I do not care. I have never heard any computer generated music that can even come close to a great composer or musician, the differences are obvious. What appeals to the audiance is never the way to write music. It is how to please record companies, but is artless garbage that is as quickly forgotten as fast as it is created.

    Anyone who takes an intermediate signal processing class learns about Princ. Component Analysis (PCA). Loosely, it attempts to represent a set of signals as weighted, linear combinations of sub-signals..... The technique allows you to find the pieces of signal that are common to the overall set. In this case I'm sure they are lining up some radio feeds, performing PCA, doing a little trivial stuff to it, and synthesizing their own "music" based on some transformation of the PCA weights and computed vectors. Not a big deal -- more like a one afternoon project for a grad student, or maybe a class project for a few undergrads...

    Does anyone else find that sort of metallic noise familiar? It sounds uncannily like the effect of an audio processor called a ring modulator - also known as a multiplier. What's the betting they're just multiplying together all the inputs?
