Re: [music-dsp] DSP/Plug-in Developers in the Big Apple
Hi, I’m a graduate student at NYU studying music tech. Am very interested in DSP but haven’t found much in terms of companies or developers in the area. The music engineering technology program at Umiami seems to be more focused on developing DSP effects. One of their professors, Will Pirkle, recently released a book on the subject.

[music-dsp] Frequency bounded DSP
Hi all, A little theoretical experiment, with practical applicability. Everybody has heard of the idea of Aliasing Distortion, right ? So what can we do to prevent it? We want to prevent it because there's a beautiful Sampling+Reconstruction theory, that says we can sample *any* signal that is frequency limited, such that it has no frequency components above half the sampling frequency, and from those samples we can *perfectly* reconstruct the original, actual signal. So the next question is, that I referred to a little while back, how can we construct such signals, and can we construct those signals at all, even. Well, evidently we can, a sine wave starting at t=-inf can be Fourier analyzed to have a very simple spectrum (a single peak corresponding to the sine frequency and with the size of it's amplitude, depending on your mathematical analysis type). So if we take a sine wave signal, lower than the Nyquist Frequency, we're good: we sample the sine wave at equal distance, and we have complied with sampling theory, so in principle we can entrust the signal to be properly put into a zero-distortion sine wave coming out of our (ideal) speakers, provided we have a perfectly reconstructing Digital to Analog Converter (which we don't yet, but we can high quality upsample, pre-analyze and somewhat even outthe errors and make something of it anyway, practically for the moment). Advantages: the signal is completely sample-independent, meaning the theory guarantees the samples are unnoticeable, no matter what the exact phase of the sine is, where the zeros and peaks fall between the samples, and the whole theory is theoretically perfectly linear, so we can use the waveform decomposition theory to built *any* waveform by adding the proper number of sinewaves and their proper amplitude. A few problems remain, one being that we'd like to be able to enforce some sort of modulation, at least some form of amplitude modulation. That poses us with the problem of the choice of t=0, the shifting of the s-transform, transient behavior that possibly isn't frequency limited, etc, but for the moment, for this experiment, we can make an example of a simple amplitude modulation of one sine wave with another, which, computable with the proper LaPlace/Fourier theory, leads to a signal which looks like a repeating wave-envelope (AM modulation), and a spectrum containing the sum and difference frequency of the sine components of being multiplied. AS long as sum and difference are lower than Nyquist and 0, we're cool: we have a perfectly frequency limited signal, so the perfect reconstruction part of the Sampling Theory states we can make a perfect analog equivalent signal out of this. Of course, the waves in principle will have to start at t=-inf, but that leads to deeper theoretical considerations. Now, can we do better, can we make, say, some form of other envelope that is still frequency limited ?

Re: [music-dsp] DSP/Plug-in Developers in the Big Apple
Well, the music-dsp list lives in New York City! And all of the universities in the city have active computer music programs. Plus there are lots of freelance developers and several audio-oriented startups. I'd recommend checking out the various music hack days, hacker spaces, dorkbot, experimental music venues, etc. All sorts of interesting audio fun happening in NYC! best, douglas On Thu, Jan 2, 2014 at 2:01 PM, Price Smith pritchardsm...@gmail.comwrote: Hey guys.

Re: [music-dsp] DSP/Plug-in Developers in the Big Apple
There are all sorts of smaller venues that have strange/experimental music every night. Roulette and Issue Project Room, for example. best, douglas On Thu, Jan 2, 2014 at 10:20 PM, robert bristow-johnson r...@audioimagination.com wrote: On 1/2/14 8:40 PM, Douglas Repetto wrote: Well, the music-dsp list lives in New York City!
