Re: [PD] How to increase audio latency on linux?
So the current state of affairs is that it is not easily possible on linux? Is this in the responsibility of the application or the audio back-end? I ask in order to find out whether this is the right list to discuss the issue. It remains in the dark what the author of the ubuntugeek article meant by good, respectively bad sound quality. Is there any strong indication that this will help in increasing the latency? If my intent to have an as huge as possible latency in order to decrease likeliness of drop-outs, it is still advised to use a low latency kernel and run Pd/Jackd with realtime priorities? Or would I be better off then with standard settings?

Re: [PD] How to increase audio latency on linux?
grasping at straws but... maybe try Alsa using callbacks - so that Pd maintains the FIFO instead of having ALSA do it. I think you can do this by opening ALSA through portaudio, requesting blocking in Pd but replace #if defined(__APPLE__) #define FAKEBLOCKING #endif with just #define FAKEBLOCKING in s_audio_pa.c I haven't tried this - don't have time right now - but if you're willing I'd be eager to hear how it turns out :) Miller On Sun, Dec 09, 2012 at 11:12:01AM +0100, Roman Haefeli wrote: So the current state of affairs is that it is not easily possible on linux?

[PD] Sound localization
Hello people, I'm trying to build a patch with which I can locate a sound source with microphones (right now using the Playstation Move Camera with the build in 4 channel microphone array). So far I found out that there are 3 ways to locate sound sources (correct me if I'm wrong): 1. Energybased method: Basically you check the loudness of the sound with at least two different microphones in a microphone array. By doing this the microphone which is further away to the sound source gives a signal which is more quiet, so you can roughly determine the location. Problems: - You need a completely quiet room for best results - Walls reject the sound wave, which gives irregularities 2. Beamforming: You get the direction of the sound by delaying the array signals and summing them up, thus creating a direction response of the array. How the exact process works and why is a mystery to me so far. 3. Time Delay Estimation-based Localization: You calculate the delayed time of the amplitudes peaks and get the result in milliseconds. By this you can determine which microphone is closer to the sound source Attached is a small patch where I tried out the energy based method with the bonk utility, the results I get with that are quite sloppy Pegeldifferenz.pd Description: Binary data Anybody there who already tried something with locating sound in pd? Or got any good advice? Thanks in advance, Matthias___ Pd-list@iem.at mailing list UNSUBSCRIBE and account-management - http://lists.puredata.info/listinfo/pd-list
Re: [PD] graph on parent problem?
Hi, I looked at your patch and it actually has nothing to do with the array being displayed via gop but rather the VU meter. Namely, your patch reads from the input and uses [env~] object to capture input values. What you didn't do, however, is given env~ object's buffer size, and I think it may default to some awfully small buffer size, so you are asking VU meter to update gui possibly thousands of times per second. To fix this, simply do env~ 16384 or some other power of 2 number and you will be fine. Checked here, after doing this it works fine. You can also try to enable gop but remove vu meter from it and I suspect it will run heck of a lot faster... If ever in doubt, you can always run pd-l2ork (or pd) with -d 3 flag which will output to console all the gui communication. I did this and found bunch of calls with RCOVER in one of the tags and traced that to vumeter external.

You can delete the registry settings for Pd-extended in:

The portable version might still write to the registry if you change the
preferences.

Re: [PD] data structures in abstractions
Hi, I noticed the gop doesn't work on pd-ext 0.42-5, but it works on 0.43-4 (w7). Another bug that was already there: if you drag one control point to outside the gop window, the struct doesn't respond to the mouse control anymore - although it still works properly. In my abstraction [jmmmp/bezier] I use messages to put the struct back into the gop boundaries. About the name and arguments always showing, it's a bit annoying. I think I made an extra [donecanvasdialog 1 -1 2 -20 120 120 -20 $1 $2 0 0, dirty 0( in [bezier] to enforce this choice. Maybe there's something broken in the code, that it doesn't let the option be taken? João Thanks Jonathan You are a magician. You said it works, so now it does no bugs. The only thing I can't get rid of is the datawindow name appearing in the graph on parent. No matter how many times I turn it off, once I save it and load it again, it comes back on. The name of the main graph on parent does not show, only of the subpatch I attached the abstraction here Cheers Eldad ___ Pd-list@iem.at mailing list UNSUBSCRIBE and account-management - http://lists.puredata.info/listinfo/pd-list

Re: [PD] graph on parent problem?
My latest fixes should help with the problem you describe. Basically, the GUIs will only request a redraw when there is an actual change. Oded, can you try it with a Pd-extended 0.43.4 beta build? Or post the patch so I can try it. Another optimization I've been thinking of is sending GUI updates on a clock, so the updates will be sent at around 60Hz, since that's the rate the vast majority of screens update at these days. .hc On Dec 9, 2012, at 5:53 PM, Ivica Ico Bukvic wrote: Hi, I looked at your patch and it actually has nothing to do with the array being displayed via gop but rather the VU meter.
