Re: [PD] 2 pole lpf with resonance?
Hallo, Vreahli the Audio Bandit hat gesagt: // Vreahli the Audio Bandit wrote: Hiya. Okay - so here's the skinny. I set out about a half hour ago to figure out how to set up a 2 pole low pass filter with resonance in Puredata. Looks like that's apparently set up with a biquad~ filter. I read through the rather handy looking information over here at http://www.musicdsp.org/files/Audio-EQ-Cookbook.txt. I came out of that a bit more confused than when I went in. I also bumped in to http://www.creativesynth.com/MAXMSP/001-SynthBuildingMSP/sbm_03.html - which left me drooling quite a bit more than when I went in. Is there any way to set up a LPF with a live-tweakable audio rate resonance and frequency setting while avoiding doing the biquad math by hand? I can't even figure out how to get my computer to crunch those numbers for me. Thanks in advance for helping me out with this seemingly simple yet convoluted question. The biquad~ math isn't extremely hard, but of course it's still hard if you have no experience/knowledge about filter theory yet. Actually there was a long discussion about biquad two or three weeks ago, you may want to check the archive. The quickest route to getting useful biquad~ coefficients without going through the math would be the filter objects in the ggee-library (CVS at /externals/ggee/filters). They implement the equations from the Audio-cookbook. However [biquad~] doesn't have audio inputs to set the coeffs. Alternatively you could use the elementary filters [rpole~], [rzero~] etc. They accept signals for their parameters. Maybe I should sit down and build a 2plp now ...

hi all i'd like to create a patch, that measures the distance between the speaker and the microphone. my first problem is, that i don't know which kind of signal would be suitable for that purpose. the simplest is to use a dirac impulse. but on the receiver-side it's hard to separate unwanted artefacts from the impulse itself. also it would be nice, if it would be possible to detect the signal reliably at different amplitudes, since the amplitude heavily changes when moving the mic closer to and farer from the speaker. i am looking for a method, that allows higher precision than the usual block-size (which introduces a grid of ~0.5m @ 44100Hz, which is not very accurate). also should it be possible to detect the signal correctly, when there was reverberation added from a room. i know, there are ultrasonic-bases devices to measure a distance to a wall, but i don't have clue how they work, but it makes me hope, that something similar is possible with pd. any hints are much appreciated. roman ___ Der frühe Vogel fängt den Wurm.

hi david pd doesn't distinguish between floats and ints, since all numbers are 32-bit-floats in pd (whereas max/msp DOES distinguish between floats and ints). so what actually happens in your example, is that all numbers are converted to floats (ints are converted to floats, not the other way around). afaict, this shouldn't be a problem as long as you stay in pd. a problem might occur, when you want to send numbers from pd to another app like max/msp. when you want to send '1.0', this is turned to '1' by pd, so the app on the other side might think, it is an int, though it is meant to be a float. i don't know of a nice way yet to overcome this. roman On Wed, 2007-02-14 at 08:35 -0500, David Brynjar Franzson wrote: Hey, I am working on a project that sends OSC messages from PD, and for some reason, when dealing with message lists of mixed objects, such as [send /OSC/blah 0.0 1.0 1.0], PD turns the floating point numbers into int, but only when they represent whole numbers.

Re: [PD] State Saving - Summary
hello some notes about the state saving system used by netpd: the state saving is more a side effect, since the main goal was to provide a system, that makes sure, that all patches have the same state, no matter when a user joins a running session. since that was implemented, it was very easy to use the same system to write states into files and store them again. the netpd-framework only provides functionality to save states of single patches. if you want to save the state of all opened patches, you would need to write your own preset-manager (which is not that difficult and there are already examples). anyway, the netpd-state saving system is made for netpd and does only work for netpd. also i think that other systems like ssad are a bit more straightforward (though i haven't had a deep look into it yet). supports: -floats -symbols -arbitrary lists -arrays (-and some specialized types more..) disadvantages: - is not universal, works only in netpd roman On Wed, 2007-02-14 at 14:16 +0100, Luigi Rensinghoff wrote: Since it is an ever returning subject maybe its good to have a summarized topic for this.

Re: [PD] g_save-0.1 Storage system with pool
Hallo, guillaume rabusseau hat gesagt: // guillaume rabusseau wrote: Yep, that sound good. I would be very glad to help... maybe integrating a nice gui interface on sssad? Okay, I added some of the GUI stuff for sssad I had already built to the CVS now. Though I'm convinced, that this stuff is better built by every user on his/her own. Why? sssad has the saving completely seperated from the state collecting. You can use sssad to save to textfiles, messages, pool-files, netsend or whatever you choose to use for the actualy saving. IMO it doesn't make sense to completely standardize this area, as saving needs are different. Anyway included the CVS now are examples how to use sssad in to save to pool, textfile and message boxes. The problem is that you'll always have to put specific symbol for send and receive pair on gui objects or to link your gui objects with some sssad object... Maybe it could be nice to have gui objects that automatically send their data with a determined symbol like patchname-$1-var_number (with the $1 only for abstractions) One of my priciples is, that state saving is not tied to GUI elements. One may want to save different things than just the state of a slider, and one may want to not save the state of some sliders. See http://footils.org/cms/show/1 for a longer take on my motivation for this. But in sssad/gui you can find some examples of GUI elements that are created like [sssad-hslider SAVEME]. They will look like normal sliders, but in fact they are slider-abstraction with graph on parent and hide object names enabled. Additionally inside they have a [sssad $1/slider] object already connected. Of course you cannot directly reach the sliders Properties dialog directly anymore, so I don't want to advocate using these directly, they are more intented as an illustration of the idiom. As I wrote above I prefer to let users make their own choices and have their own thoughts, because my way often is wrong and it is so more often for others. ;) Ciao -- Frank Barknecht _ __footils.org_ __goto10.org__ ___ PD-list@iem.at mailing list UNSUBSCRIBE and account-management - http://lists.puredata.info/listinfo/pd-list

The external is an OSX version but I know I have a linux version somewhere as well. If needed I can try to find it and send it as well, or maybe I'll send the source so people can compile it themselves if interested. It should be compilable WIN and Linux as well. As there's no documentation in the patch, here's a brief documentation for the patch and the external. The DIST_HP~ external sends high-passed ( 17 kHz) impulses from the loudspeaker and then measures the fly-time of these impulses to two microphones (here input channels 1 and 2). The slider on the upper right hand corner (Impuse interval) sets the time interval (in 64 sample blocks) of the impulses, that is, how often the distance is measured. The last two outlets of the DIST_HP gives out the distance of the microphones to the loudspeaker in meters. I put a mean and a median filter on there as well to smooth the data but you may use whatever is appropriate. The distance is computed in sample accuracy. The 'free_distance_in_meters' -outlet transforms the impulse time interval to a physical distance. This, in principal, should be greater than the longest microphone-loudspeaker distance you will use. The calibration is done by using the calibration_latency -number on the left. Place a microphone to a known distance from the loudspeaker and then tune the calibration_latency so that the measured distance is correct. Increasing the latency increases the measured distance. The measured distance cycles from 0 to the free_distance_in_meters. So, when increase the calibration_latency and the measured distance reaches the free_distance_in_meters it will go back to zero and continue from there. The volume slider sets the output volume of the impulses. Note, that the impulses are high passed above 17 kHz so actually not everybody will here them! Be cautious with the volume. The whole idea of using higher frequency range was to make the impulses inaudible, and to avoid interference from room reflection and from other sounds as well. I have a version which uses full band impulses as well, but then the reflections start to worsen things.. You must use 44,1 kHz sampling frequency. Hope, it works and is usable. Once I get little extra time, I'll try to get the rest of the stuff organized and documented so I can publish them here as well. Any feedback or criticism is always welcome. -miikka dist_hp~.pd_darwin Description: Binary data positio_demo_1ch.pd Description: Binary data ___ PD-list@iem.at mailing list UNSUBSCRIBE and account-management - http://lists.puredata.info/listinfo/pd-list

[PD] Sampler loop strategies
Hi folks I'm trying to build your classic sample player, with multiple key zones etc, but I'm getting kinda stuck with looping. Any thoughts on how I might gracefully implement a player which plays a sample from the beginning when triggered, but then only loops a section, like my hardware sampler does? The best solution I can think of is to use 2 tabread4~'s: one controlled by a line~ for the initial pass, and the other with phasor~ for the loop, then crossfade them. Anybody have a better idea? I know I could just use a softsynth for this, but in a beautiful reversal, in this case it's actually easier to use pd. Take that, propellerhead. cheers dafydd -- www.sideshowmedia.ca skype: chickeninthegrass ___ PD-list@iem.at mailing list UNSUBSCRIBE and account-management - http://lists.puredata.info/listinfo/pd-list

Re: [PD] Sampler loop strategies
Hi Frank The problem with the phasor~ is that I can't get a crossfade over the loop end (unless there's something I'm missing). Bummer - my loops aren't that clean. I will look at RTC-lib. Thanks for the tip. cheers dafydd On 2/14/07, Frank Barknecht [EMAIL PROTECTED] wrote: Hallo, Dafydd Hughes hat gesagt: // Dafydd Hughes wrote: The best solution I can think of is to use 2 tabread4~'s, crossfading for every pass of the loop. Anybody have a better idea? I'd do the looping a bit differently: Standard would be to use a [phasor~] scaled so that it plays a certain section of the sample with [tabread4~]. Example: Assuming you want to loopplay samples 1000 to 1050 at a loop-frequency of 100: [phasor~ 100] | [*~ 50] because: 50 = sample_end - sample_start | [+~ 1000] because: 1000 = sample_start | [tabread4~ yoursample] Playing the sample in full could be done with [vline~] as in one of the example patches in the docs (or use [play-samp~] from RTC-lib]. Now the tricky part is how to switch from the normal play to the looping phase without clicks. Maybe this can be realized most easily by just crossfading from the [vline~] player to the [phasor~] loop. Again RTC-lib might be useful: It has a little [crossfade~] abstraction that does constant-power crossfades.

Hi, I wonder, if I set loop points in SoundForge, which is my sound editor of choice (unless I'm doing very simple command line stuff in Sox), if PD has any way to get the .WAV metadata about the loop points??? Anyway, regardless of that, when I load samples into Native Instruments Intakt, I can set my own loop point on the fly. I often use this with glitchy samples, to choose a small portion and get an arbitrary pitch based on the loop length. The other thing that's cool is to take a longer sample - say of some kind of weird industrial machines - and arbitrarily set the loop to random points. I suppose looping a clarinet or cello sample would be a whole different story, I guess if I'm working for something so traditional, I'd rather find something pre-looped than be bothered with that kind of pedantic thing... which again makes me think how nice it would be to support some different sampler formats in PD! ~David ___ PD-list@iem.at mailing list UNSUBSCRIBE and account-management - http://lists.puredata.info/listinfo/pd-list
