You could try using a multiband filter and some envelope followers, but I don't think you will be able to measure the voting very accurately using this technique. To get slightly better results, you might want to take into account the effect of frequency on perceptual loudness (cf. Zwicker et al). You should also take into account whether or not the various votes are synchronised in time by taking measurements over some time frame, and averaging the results. There are also other issues to consider such as the fact that not all of the voters will strike the xylophone equally hard, the resonance/absorption qualities of the room, and establishing the correct relative contribution from each microphone. Basically, this is a difficult problem to solve, but if all you need is a 'rough idea' of how many votes have been cast, you might be OK.

Re: [PD] Cymatics/Chladni figures simulation
The patterns probably depend on the stiffness of the plate/membrane as well as its shape, and the grain size and density of the sand. It should depend on stiffness, density and shape. The speed of sound in a material is sqrt(stiffness/density). The partial differential equation for waves depends on these two constants, and the amplitude of forcing. The units are a little tricky (and they are different depending on the number of dimensions) I have been engrossed by this idea, since I read it on the list :) I'm sure you'll have a lot to research to make this work, and I really hope you make something cool! By analogy with the Karplus-Strong vibrating string, which is a one-dimensional CA, usually the stiffness of the string is ignored.

Apart from the difficulty of doing a 2D KS, there is the further complication of an external frequency forcing (maybe introduced at the edges of the plate?). Martin I see the edges as being different kinds of boundary conditions, Dirichlet, Neumann, and Robin. Dirichlet - amplitude is zero at the boundary (reflected waves are 180 deg out of phase) Neuman - 1st deriviative is zero at the boundary (reflected waves are in phase with incoming waves) Robin - 1st order differential equation (specifies a constant phase difference between incoming/reflected waves) ___ PD-list@iem.at mailing list UNSUBSCRIBE and account-management - http://lists.puredata.info/listinfo/pd-list
Re: [PD] Real-time frequency filtering and analysis
filtering in general may not be the best approach because some of your partials from one xylophone note will overlap with other note's partials. They are inharmonic complex tones, which are not so easy to predict you'll probably have to measure the frequencies of each note of your xylophone to know exactly what the spectrum is like. In terms of averaging like Jamie suggested... suppose you want to compute the expectation of the power spectral density. You would take the fft of the auto-covariance of your recieved signal, divided by the number of blocks in your time frame. (dividing by a number of blocks will not in general be necessary, when all you need to do is find a peak, with pique~ as before) This will give you a very clear/accurate peak, without much jitter/noise to clean up.

Re: [PD] Real-time frequency filtering and analysis
you could also check sigmund~ it will give you a list of frequencies and amplitudes in order of amplitude. J I think this just reinforces what everyone is saying about the errors. Either you make it into a crazy competition to vote by banging your note the loudest and the mostest, or you accept a margin of error. As Jamie says the intensity and frequencies are all going to vary and interact. attached patch intented to investigate that, it makes little clusters of 10 votes (idealised sinewave xylophone) separated in time by a value between 0 and 100ms at one of 3 frequencies chosen at random. What you wont get in reality is the notes being exactly the same frequency, there should be a fair degree of variance. When I used a focused noise source to approximate the xylophones inharmonic spectrum I couldn't see any correlation above chance. YMMV, especially if you tweak the windows/blocks . I got better initial results with the filter bank approach I think.

Re: [PD] attack/release for spectral gate [was: is this a spectral gate?]
Hi Chuck! Actually I was working on it tonight. The problem with it is that it is too harsh and leaves too many artifacts on the signal right now because the binary [~] from zexy needs to be smoothed out with attack/release that persists across different blocks in time. What I tried tonight was successive delay lines where the block starts out at 0.25 of its original amplitude, then passes to another delay and is amplified to 0.5, then to 1, held at 1, down to 0.5, and then to 0.25 and back off. Successive delay lines that increase and then decrease were the only way I could think to do this job of smoothing it out over time and preserve information from past blocks of audio. I've attached the patch as I was working on it tonight. However, this has some problems of its own and I was getting a lot of high frequencies that I didn't want there, so I think this approach will need to be windowed as well - the delay lines may need to be smoothed too, something along the lines of the pitch shifting example in the documentation, except in the frequency domain?? I dunno and I'm in a little bit over my head at this point. It's hard to measure and assess what you do right and wrong in the frequency domain! Sometimes a brother just needs a scope. I am also open to fact that I am completely wrong about this :) What you're describing, if I read you correctly, is I think implemented in the noisegate example in Pd's doc... if they are different, could you clarify? but all of these just sound bad to me and of poor quality, they really need attack and release to sound convincing/interesting and less artifact-y when you really push them. I'm all for destruction/mangling of audio, and FFT seems truly powerful in that regard, but I just don't like these results yet. Of course, Tom Erbe's soundhack filters already do this, but he hasn't responded to this on how he got attack/release to work for him - it may need to be handled differently in Pd as opposed to whatever he used to code those VSTs. That said, I would *love* to hear/try what you come up with. Let's be in touch about this! Kevin On 3/28/07, Charles Henry [EMAIL PROTECTED] wrote: Hi, Kevin, I liked your idea for a spectral gate. I can see two possible applications for it: 1. removing broadband noise from signals 2. masking out one sound from a collection of sounds And the first option is especially cool. It would be like a noise gate on steroids, because it would remove the noise, even when there's a signal present. If it's alright... I'd like to give it a try, and send it to you. I'll re-format it so that one signal (noise or whatever) can be recorded and then used to mask the same signals out of a continuous signal input. In fact this can be reformatted as a kind of weiner filter, which will optimally reconstruct signals in the presence of noise. Have you gotten this working the way you want yet? Chuck On 3/23/07, Kevin McCoy [EMAIL PROTECTED] wrote: Hello all, A while ago I was working on a spectral gate patch and now I've come back to it. Here's a quote from Tom Erbe's earlier email: For a spectral gate, just calculate the amplitude from real and imag, make your gate decision based on the amplitude and threshold, and then apply the same gain reduction to both real and imag. Add attack and release to the gate-gain for smoother results. I want to add the attack and release so it sounds smoother and less bubbly/harsh (know what I mean?) I am racking my brain trying to figure out how to do this to each of the frequencies. The soundhack vst does this really nicely and even has a visual representation of the gate where you can see it rise and fall with attack/release for the whole spectrum. The problem for me is persistence across different blocks. I suspect [line~] doesn't work for this as it does for amplitude attack/release implementations. For example, if there is a spike around 3000 Hz, how can I carry that attack and release across several blocks of audio? I used delay objects with what I thought was some success, but I don't think I had it right. I have attached the patch which is basically what Frank posted earlier - it does not have any of this yet and is just a hard on/off. Much confusion, I would be grateful for any help!
