[PD] sending audio panning with 4 speaker setup
Hey all, So I'm still scratching my head with controlling audio panning in an x,y grid using 4 speakers. What, at first, seemed like a somewhat trivial problem, upon closer inspection ain't necessarily so. Does anyone have examples of panning with 4 speakers? About the only things I have found so far are: Building upon Hans' [pan_core~] [pan_quad~] from 'nSLAM', which seems to be unavailable for d/l The 'pd-tutorial' patch 3-9-3-1-spatial-quadro.pdhttp://pd-tutorial.com/english/patches/3-9-3-1-spatial-quadro.pd Anyone know about any others? My stereo panning is built upon the square root example in Andy Farnell's book, which I'm really happy with. Ideally I would like to expand upon that. Then of course there is the whole vbap/ambisonics/cubemixer (possible overkill) route too. My concerns before diving into this are threefold. 1. If it's only going to work for the 2 people in the 'sweet-spot' then what's the point? If it makes any difference I'm using some Bose 180 degrees radiating speakers. 2. The piece is for a performer with electronics, with only the electronics coming out of the speakers. So I'm also wondering whether a 5.1 type setup with the performer as the front centre speaker (as such), may be preferable? 3. The piece requires 96 separate pan positions - how cpu intensive is that going to be? It currently works fine in stereo, which is why 2 lots of stereo in an x,y fashion seems initially preferable. I'm aware that it's pretty much impossible with this speaker setup to make everyone in the room have a similar audio experience, and also to map my visual masses from an msd swarm in the GEM window as audible points, but surely it is possible to do this as an x,y grid. I also admit that I don't understand the dsp theory necessary to make the x,y, grid idea happen so if anyone has some pointers regarding that I would be delighted.

Re: [PD] sending audio panning with 4 speaker setup
Ambisonics isn't necessarily overkill, but it only gets you direction, not distance -- it's only a 1-dimensional solution, in the sense that you'd be panning around the outside of a circle but not to locations within that circle. It's not terribly CPU expensive. If you do want distance as well you can use some combination of delay, low-pass filtering, and wet-dry mix of any reverb you happen to be using (and if you want to get really ambitious, you can also simulate individual room reflections). This starts to get CPU intensive especially if you're going to be moving sounds around. If they just stay in place, it's not as bad (and the [delwrite~] [vd~] model doesn't actually model moving sources a certain distance from the virtual microphone -- it models a moving microphone, so a simple Pd solution isn't quite available).

Re: [PD] Patch for Akai EWI (was Reading and writing binary files)
Hi David, P.S. Did you mean midi channel or midi port? The inlet to EWI-send is for the midi port. The midi port depends on your hardware. That cannot be known. The midi channel is 1 (like in Pd) however the EWI needs numbers between 0 and 15 while the common use of midi channels goes from 1-16 (like in Pd). So the patch needs to show 1 while it is transmitting 0 to the EWI. As far as the default values in general: Only a few of them are important to be set to a specific value. Two of them are the pitchbend settings which need to be set to 127. They do nothing at 124 or 125. I thought you tested this? (Although I have to admit that I have not updated the firmware or software within the last 6 months.) Ingo -Ursprüngliche Nachricht- Von: David [mailto:dfket...@gmail.com] Gesendet: Montag, 14.

The only error you mentioned specifically was the need to send the NRPN message (and thanks for that). However, I looked at the files produced by the Garritan software, and they seemed to agree with the defaults on that web site, as far as I can remember. Maybe it depends on which version of the firmware and which version of the Garritan software you're using, I don't really know. In any case, they can be overridden, that's the whole purpose of writing this patch in the first place. As for the Midi channel, I'm not sure whether the first midi channel is supposed to be 0 or 1. It's just the default anyway, it's going to have to be changed, depending on how many midi devices you have attached, and in what order. Although I told that some of the stuff is incorrect and provided you the correct information you simply copy this wrong information and want to publish it somewhere else with your own copyright??? The copyright isn't on the information from his web site (which I'm not reproducing anyway), it's on my PureData code, so I don't really understand what you're complaining about. Come on!

Re: [PD] sending audio panning with 4 speaker setup
Hey Matt, Thanks for pushing my understanding along...

Re: [PD] sending audio panning with 4 speaker setup
Can you describe your 2d space a little? Is there a reason for wanting 48 discrete spots rather than one continuous space? I actually think the 48 spots could work, but I'm curious how it is supposed to sound when something moves through the space (or do sounds just pop up periodically at those discrete spots)? There is another ambisonic trick I have heard of but haven't yet tried, which is to add a 3rd dimension in the encoding but still decode to a 2d space. The space then becomes a kind of projection of the 3d space onto a 2d space, so you can move closer to the center by increasing the elevation of the direction. Directly upwards in the encoding sends the same signal to all 4 speakers on decode, so that it sounds in the middle of the space.

Re: [PD] Problems going fullscreen on external projector
On Thu, 10 Mar 2011, Antonio Roberts wrote: I've made a simple video mixer in Gridflow (9.13) and I want to send the output to an external projector. I've set up my computer so that I can drag windows to the second screen, but when I attempt to go full screen using [#out sdl] and then pressing Esc it goes fullscreen on both screens. Sounds like the kind of problem that can't be solved in GridFlow. It's a SDL issue. If I use an [#out window] object, which I believe is an x11 window, there's no way (that I can find) to go full screen, so I'm stuck at with an 800x600 window on a 1366x768 screen. I did attempt to use a [#scale_to (768 1366)] object to emulate being full screen but the scaling causes a massive drop in framerate. Changing the screen resolution is a sure way to avoid even having to scale. [#scale_to] is a simple abstraction not meant to be fast or fancy. It would be a good thing to make a much better software scaler for GridFlow (interpolating and faster), but it wouldn't be as fast as a hardware-accelerated scaler, or simply changing the screen resolution. Changing screen resolution also gives you the best image quality when using a CRT, whereas on a LCD it just means you're getting the LCD monitor to do the scaling for you. Can anyone suggest how to go fullscreen on only one screen, how to go fullscreen using an x11 window or some other way to do this? There is the border method for removing the border, the move method to put a window wherever you want (compute window coordinates to match the way the mouse travels from one screen to the other).

Re: [PD] sending audio panning with 4 speaker setup
I probably haven't described the space particularly well, I attach a picture to hopefully explain a little clearer. It's a 'swarm' of [msd] masses and links, with only the masses visible. The swarm is in a zero gravity space so they just float around. The space receives bangs/force at various points on the x-y grid triggered by an accelerometer attached to the performers instrument. So the swarm is in constant motion, sorry if that wasn't clear. At the moment I'm just using the coordinates on the x plane of each mass, which msd handily spits out. I have patched in the option of using the y coordinates but I haven't used them as of yet. Each mass controls the pan position of a partial (of which there are 48) from the instrumentalist and fed into [sigmund~].So the pan position of each mass/partial is slightly different in the (currently) stereo field across 0-1.

Re: [PD] sending audio panning with 4 speaker setup
Swarms are in! A pal of mine is doing something very similar: http://www.youtube.com/watch?v=Ao258ciSMSg I misunderstood your space before -- you have 48 things that you want to pan around a 2d space, but I thought you meant you wanted to pan stuff around a 2d grid which itself had 48 points. If it were me I'd almost certainly use ambisonics with the projection I mentioned before, but you'd have to do some trigonometry to map x-y to the surface of a half-sphere above the space, and I think you'd have to figure out a way to scale to keep the power the same. The reason I'd use ambisonics is that I would not want to have to redo the engine for a different speaker setup -- I could just throw the encoded stream to another decoder. On the other hand, there are other, simpler ways of doing 4-channel panning if you're committed to a 4-channel setup. There are probably externals I don't know about, or you could model it after something like the Pan4 UGEn in SuperCollider, which uses a simple product of two equal-power curves (using trig functions), one for left-right and one for front-back, such that the front-left speaker gets left*front*input, the back right gets right*back*input, and so forth. The thing about moving stuff around in space like this is that there are some situations (probably not this one) in which you'd want to also simulate doppler shifts. Panning doesn't do this, but you can simulate all that stuff with delay lines (and again, if you really wanted to do it, you'd need a variable delwrite~ rather than a variable delread~ == vd~).

Hey Matt, Well, good to hear the zeitgeist hasn't completely deserted me then:) Yes I'm sorry, I wasn't very clear on what it is I'm working with. That thing of, I've been working for ages on this and can't quite understand why it's not bleedin' obvious to everyone else... So, ambisonics then - eek! Well I have to say my trigonometry is dreadful, not something I'm proud of, just wish I had paid a little more attention in maths classes as a teenager - too busy dreaming of pop stardom and how I would never need any of this stuff. Many is the time when I have heard the ghost of my maths teacher snickering over my shoulder since I got into Pd. I'm gonna do some experimenting and reading up before I dive into anything. There seems to be the Holzmann tutorial, plus all the iem stuff to wade through. The Cubemixer looks interesting but also hefty (back to the possible overkill) and also as msd doesn't work on my usual Puredyne OS I'm moonlighting in W7, so super unsure about compiling stuff in W7 plus the performer runs on a mac, so then setting it up for his machine as well. Aaargh. Plus the 1st performance is now only 2 weeks away! I think the simpler the better basically. Cheers for weighing in though Matt, hopefully speak soon.

Each mass controls the pan position of a partial (of which there are 48) from the instrumentalist and fed into [sigmund~].So the pan position of each mass/partial is slightly different in the (currently) stereo field across 0-1.

Is there a reason for wanting 48 discrete spots rather than one continuous space? I actually think the 48 spots could work, but I'm curious how it is supposed to sound when something moves through the space (or do sounds just pop up periodically at those discrete spots)? There is another ambisonic trick I have heard of but haven't yet tried, which is to add a 3rd dimension in the encoding but still decode to a 2d space. The space then becomes a kind of projection of the 3d space onto a 2d space, so you can move closer to the center by increasing the elevation of the direction. Directly upwards in the encoding sends the same signal to all 4 speakers on decode, so that it sounds in the middle of the space.

Re: [PD] sending audio panning with 4 speaker setup
Probably the best bet would be to make an abstraction for spatializing an individual partial that has the panner built in at the tail which would throw~ the 4 channels to catch~es elsewhere in the patch. Then it wouldn't take much work at all to swap it out with an ambisonic panner later that took the same input sound, X, and Y inputs at a later date. With that deadline maybe I would then make some kind of equal-power quad panner (e.g. the product of a front-back and left-right panner like supercollider's Pan4) or use an external. There's still the CPU question, which might be rather severe with 48 of these going on at once, plus whatever else is going on. I have once in a while needed to sync up two computers via lightpipe and netsend, doing all the control and initial processing on one end and then final processing on the other end... and it's good if timing doesn't have to be sample-perfect. Of course you can't send 48 channels across lightpipe, so maybe you could have one computer calculate all the swarm stuff, do anything with the accelerometer, and run Gem, and just send info via netsend/netreceive to the other which would be running your sigmund~ setup and the spatialization. Note that you're going to have to use line~ for the X and Y panning coordinates so that you don't get discrete jumps in the panning location. Too many options!

A pal of mine is doing something very similar: http://www.youtube.com/watch?v=Ao258ciSMSg I misunderstood your space before -- you have 48 things that you want to pan around a 2d space, but I thought you meant you wanted to pan stuff around a 2d grid which itself had 48 points. If it were me I'd almost certainly use ambisonics with the projection I mentioned before, but you'd have to do some trigonometry to map x-y to the surface of a half-sphere above the space, and I think you'd have to figure out a way to scale to keep the power the same. The reason I'd use ambisonics is that I would not want to have to redo the engine for a different speaker setup -- I could just throw the encoded stream to another decoder. On the other hand, there are other, simpler ways of doing 4-channel panning if you're committed to a 4-channel setup. There are probably externals I don't know about, or you could model it after something like the Pan4 UGEn in SuperCollider, which uses a simple product of two equal-power curves (using trig functions), one for left-right and one for front-back, such that the front-left speaker gets left*front*input, the back right gets right*back*input, and so forth. The thing about moving stuff around in space like this is that there are some situations (probably not this one) in which you'd want to also simulate doppler shifts. Panning doesn't do this, but you can simulate all that stuff with delay lines (and again, if you really wanted to do it, you'd need a variable delwrite~ rather than a variable delread~ == vd~).

[PD] pix_image can't open some tiffs
Hi, I have a tiff image which was saved with Photoshop with the settings listed below (I would attach it, but my internet connection now is so bad that it fails to send the mail if I do it!!). Pix_image silently fails to read it (or maybe it reads it as an all-white image, but i think it's the former, since pix_info returns -1 as width and height); however I can see it correctly in Image Viewer (the default image viewer in Ubuntu) and in GIMP. If I open it in GIMP and save it again into tiff, pix_image reads it correctly. However GIMP doesn't offer as many settings as Photoshop. Does anybody know which of these settings is not supported by pix_image (if any)? (do you know any kind of tiff inspector for Ubuntu?) Here are the settings: Image compression: LZW Pixel Order: Interleaved (RGBRGB) Byte order: IBM PC Save Image Pyramid (checkbox): no Save Transparency (checkbox): no Layer Compression: RLE I guess these are the default values in Photoshop (I don't have it, I was sent a screenshot of the settings they saved the image with).

Re: [PD] sending audio panning with 4 speaker setup
Sorry, didn't reply to the list before. I'm going to leave it as is but I have stuff to add... Pd and its community is bloody marvellous. A few hours ago I knew nothing about vbap or ambisonics apart from going to some concerts/installations where they have been used and occasional list-chatter. I now have a basic working knowledge, with some additional questions that I think I can locate answers to fairly soon (well not today, I've pretty much had enough now). Hopefully I can do some coding and get myself in a studio and hear what's going on and code some more. No doubt there will be more questions to come but I at least feel I can get started. Many thanks for holding my hand (so to speak) with this Matt and big props to all the IEM bods, especially Georg Holzmann for his spatialisation tutorials. (Big aside here) Speaking of IEM, I have an ongoing discussion/argument with a MaxMSP/IRCAM advocate who is most disparaging about the whole FLOSS thing. I think IEM set an excellent example for what I like to think of as the right side to be on, a real 'rebel alliance' if you will. Like IRCAM are going to make their no doubt millions of Euros worth of yearly funding back by selling a few Max externals. Rant over. Calm is restored. Cheers, Julian Right then Matt, I'm going to pester you (chisel as we say in Northern England). I have attached my current stereo square root panner (I can make it equal power if that's the best way to go) - am I right in thinking I need to add and subtract 90 degrees to this signal to get the basic quad working. If so, how and where? I'm sorry, I have looked at the supercollider code, and although it seems quite straightforward, I have no idea how to implement that in Pd? I am in the process of ripping my patch apart and using 2 instances of Pd to help with the cpu load but I must admit to being wary of doing too much on that front until I know what's happening with everything in the patch then splitting the load when things are a little clearer. Going through the Holzmann tutorials as we speak. very good too.

[PD] Dynamic patching with audio - review
Hi dynamic community, I'm working on an open source multiuser game with a sound experimentation focus. The choosen sound engine is our favorite one Pure Data. Let's imagine populate a 3D world with pd sound patchs ! The issue is to create/destroy audio abstractions (made by users/artists) and connect/disconnect them. The audio path system must be compliant with paths in a 3D world. A sound pass through rooms and apertures : http://abel.jerome.free.fr/newatlantis/AudioDynamicPatching/images/pathfinding.png It must be dynamic like a game. I was enjoying doing this with pd, but ... my hair become more and more white. It's quite difficult. I propose here to write a little review of this issue. To be completed, to be rectified. Don't forget that the best is the easiest way (less compilation, less dependancies, less bad tricks, etc.) and cross-platform (Linux/MacOSX/Win). ** *** DYNAMIC PATCHING TESTS *** ** All my tests and comments here (patchs, screenshots) : http://abel.jerome.free.fr/newatlantis/AudioDynamicPatching.tar.gz 1 - PURE DATA -- First, considering audio in Pd, we can read do not use dynamic patching !! http://puredata.info/docs/tutorials/TipsAndTricks#how-to-avoid-audio-drop-outs It's not very encouraging. So what ? Which tool use then ? A comparison of audio tools : http://en.wikipedia.org/wiki/Comparison_of_audio_synthesis_environments 2 - SUPERCOLLIDER - Supercollider seems to work well with dynamic audio connections. We can read Adding an Effect Dynamically and so on. http://danielnouri.org/docs/SuperColliderHelp/Tutorials/Tutorial.html It is an efficient and expressive dynamic programming language http://en.wikipedia.org/wiki/SuperCollider So, how interface it with a pd patch ? I know that it's ok with OSC messages, but could we imagine, Supercollider as a the connection manager and Pd as the sounds loader ? An audio communication between Supecollider and Pd. 3 - PYTHON -- Some projects use Python to make dynamic patching. I don't know if those projects are really working with full functionnalities like a complete audio path system. I think the most advanced is Purity but may be not enough, see the roadmap. Any feedbacks in use ? Purity is a Python library for Pure Data dynamic patching. http://wiki.dataflow.ws/Purity Pyata - a Library that allows you to use Pure Data inside Python svn checkout http://pyata.googlecode.com/svn/trunk/ pyata-read-only Automata-topd is a small collection of Python classes to communicate with Pure Data sending FUDI messages by socket. https://github.com/automata/topd PuréeData is a browser-based PureData interface for a remote, central server that allows live, collaborative patching for anyone, anywhere. https://github.com/virgildisgr4ce/PureeData 4 - PURE DATA - LIBPD - Let's come back with Pd. We know that Pd was used in a game Spore : http://lists.puredata.info/pipermail/pd-list/2007-11/056212.html It could be a solution to handle dynamic audio patching. Any feedbacks ? Libpd turns Pd into an embeddable library, so you can use Pd as a sound engine in mobile phone apps, games, web pages, and art projects http://puredata.info/community/projects/software/libpd/ How to use Pure Data as an API http://jeraman.wordpress.com/2009/03/22/how-to-use-pure-data-as-a-api/ 5 - PURE DATA - DYN~ This external allows the dynamic creation and deletion, connection and disconnection of standard Pd objects and abstractions.

Hope you like this version a little better. David. ___ Pd-list@iem.at mailing list UNSUBSCRIBE and account-management - http://lists.puredata.info/listinfo/pd-list
Re: [PD] Dynamic patching with audio - review
Have you looked at the [switch~] object? It doesn't allow you to create/destroy the abstractions, but it does allow you to turn off dsp in each of them as necessary. -Jonathan --- On Tue, 3/15/11, Jérôme Abel abel.jer...@free.fr wrote: From: Jérôme Abel abel.jer...@free.fr Subject: [PD] Dynamic patching with audio - review To: pd-list@iem.at Date: Tuesday, March 15, 2011, 12:07 AM Hi dynamic community, I'm working on an open source multiuser game with a sound experimentation focus. The choosen sound engine is our favorite one Pure Data. Let's imagine populate a 3D world with pd sound patchs ! The issue is to create/destroy audio abstractions (made by users/artists) and connect/disconnect them. The audio path system must be compliant with paths in a 3D world. A sound pass through rooms and apertures : http://abel.jerome.free.fr/newatlantis/AudioDynamicPatching/images/pathfinding.png It must be dynamic like a game. I was enjoying doing this with pd, but ... my hair become more and more white. It's quite difficult. I propose here to write a little review of this issue. To be completed, to be rectified. Don't forget that the best is the easiest way (less compilation, less dependancies, less bad tricks, etc.) and cross-platform (Linux/MacOSX/Win). ** *** DYNAMIC PATCHING TESTS *** ** All my tests and comments here (patchs, screenshots) : http://abel.jerome.free.fr/newatlantis/AudioDynamicPatching.tar.gz 1 - PURE DATA -- First, considering audio in Pd, we can read do not use dynamic patching !! http://puredata.info/docs/tutorials/TipsAndTricks#how-to-avoid-audio-drop-outs It's not very encouraging. So what ? Which tool use then ? A comparison of audio tools : http://en.wikipedia.org/wiki/Comparison_of_audio_synthesis_environments 2 - SUPERCOLLIDER - Supercollider seems to work well with dynamic audio connections. We can read Adding an Effect Dynamically and so on. http://danielnouri.org/docs/SuperColliderHelp/Tutorials/Tutorial.html It is an efficient and expressive dynamic programming language http://en.wikipedia.org/wiki/SuperCollider So, how interface it with a pd patch ? I know that it's ok with OSC messages, but could we imagine, Supercollider as a the connection manager and Pd as the sounds loader ? An audio communication between Supecollider and Pd. 3 - PYTHON -- Some projects use Python to make dynamic patching. I don't know if those projects are really working with full functionnalities like a complete audio path system. I think the most advanced is Purity but may be not enough, see the roadmap. Any feedbacks in use ? Purity is a Python library for Pure Data dynamic patching. http://wiki.dataflow.ws/Purity Pyata - a Library that allows you to use Pure Data inside Python svn checkout http://pyata.googlecode.com/svn/trunk/ pyata-read-only Automata-topd is a small collection of Python classes to communicate with Pure Data sending FUDI messages by socket. https://github.com/automata/topd PuréeData is a browser-based PureData interface for a remote, central server that allows live, collaborative patching for anyone, anywhere. https://github.com/virgildisgr4ce/PureeData 4 - PURE DATA - LIBPD - Let's come back with Pd. We know that Pd was used in a game Spore : http://lists.puredata.info/pipermail/pd-list/2007-11/056212.html It could be a solution to handle dynamic audio patching. Any feedbacks ? Libpd turns Pd into an embeddable library, so you can use Pd as a sound engine in mobile phone apps, games, web pages, and art projects http://puredata.info/community/projects/software/libpd/ How to use Pure Data as an API http://jeraman.wordpress.com/2009/03/22/how-to-use-pure-data-as-a-api/ 5 - PURE DATA - DYN~ This external allows the dynamic creation and deletion, connection and disconnection of standard Pd objects and abstractions. But : dyn~ is bound to the PD version it is compiled for. http://puredata.info/Members/thomas/dynext I success compile it. It seems a good system. If we compile a binary for 3 or more plateforms, will it work just with the binaries ? We must see advantages with my system (pd-messages + index + abstractions) http://abel.jerome.free.fr/newatlantis/AudioDynamicPatching/images/dyn-audio-paths-dyn~.png 6 - PURE DATA - IEMGUTS --- We know reflection in Pd with iemguts. I'm not comfortable with it. Any feedbacks about the issue ? https://pure-data.svn.sourceforge.net/svnroot/pure-data/trunk/externals/iem/iemguts/ http://lac.linuxaudio.org/2009/cdm/Saturday/18_Zmoelnig/zmoelnig_pdreflection.pdf 7 - PURE DATA - PD MESSAGES --- A review with pd internal messsages. http://puredata.info/Members/eni/techniques In Pd : /usr/lib/pd-extended/doc/Pure
Re: [PD] pix_image can't open some tiffs
Hi, Does anybody know which of these settings is not supported by pix_image (if any)? (do you know any kind of tiff inspector for Ubuntu?) Pix_image uses imagemagick if installed. Try opening the file with display to see if magick can read it. Charles ___ Pd-list@iem.at mailing list UNSUBSCRIBE and account-management - http://lists.puredata.info/listinfo/pd-list
