[PD] Number box and CPU load
Hi all, I have a one quick question about number boxes and how they effect CPU load. I use number boxes quite a lot for debugging and sometimes I forget to remove them from the final patch or abstraction. So I was wondering do the number boxes cause significant CPU usage even when they are not visible? For example when the abstraction window with the number boxes is closed? -Mika ___ Pd-list@iem.at mailing list UNSUBSCRIBE and account-management - http://lists.puredata.info/listinfo/pd-list

I guess this is, because you need more cord connections to go from the random to the subpatch to the abstraction. but for me that was new. the overhead is not big, though, only around 10%. but, sending messages in general (s/r of cord connections) is quite a bottleneck in pd and I wonder if that could be improved.

[PD] earplug~ or FIR~ for HRTF?
Hi all, I'm considering whether to use the earplug~ HRTF external or some alternative implementation of binaural spatialization. On the plus side, earplug~ seems quite easy to use. On the down side, earplug~ seems not to handle any sample-rate stuff at all, so I'm wondering which samplerate the impulse responses in the earplug_data.txt are sampled at (because obviously it would be somewhat weird to use them at another rate...). I don't really need the interpolation provided by earplug~ either, so I guess I could save some CPU by using FIR~ directly, but then I need to obtain some HRIR's (ideally both at 44100Hz and 48000Hz sample rates). So: has someone already made a binaural processing patch using FIR~ and some set of impulse responses and would care to share it? Some context for the curious: I'm trying to auralize 4D space using 4D room simulation, with an ear made up of several co-solid listening points in the 4D space, each mapped to a 3D source point for binaural processing.

Re: [PD] earplug~ or FIR~ for HRTF?
IEM's bin_ambi is a sophisticated binaural rendering system via higher order Ambisonic spatialisation to virtual speaker arrays. http://iem.at/Members/noisternig/bin_ambi FIR~ is very CPU intensive for HRTF processing. It's much better to use frequency domain convolution with fft~ ifft~ which is the case with bin_ambi.

Re: [PD] Random - Different seed each time the patch is loaded
In a way~, it's not so straightforward. Let's say the random generators are identical and seeded by another identical random generator with no further modifications. Then, all the other random generators are correlated--using the same sequence, but with slightly different starting points within that sequence. so, you need to have a map of the range of random onto itself, which is different from the random sequence mapping. That way, you actually obtain seed values which are spaced far apart in the sequence.

Re: [PD] Random - Different seed each time the patch is loaded
Speaking of Lua and randoms, I had read somewhere (I think on the website) that on some platforms, their random generators will always produce the same FIRST number, but everything else after that is random. I tested this out on the Mac OS X, and yes, every FIRST number is the same, but everything else beyond that isn't. The workaround for this is to just drop the first random value you get. I don't know why this happens, but is it possible that the same things happens in PD? I have not tested this out.

The individual samples of the noise are correlated with each other (thermal noise is not white). But when you take a single sample at a given time without knowing the previous values, that correlation can be ignored, and you would generate a completely independent random number, drawn from the distribution of the noise. The only problem is if the noise is very narrowly distributed, so that you only recieve one of a few possible choices of the seed value. Compared to using time/date: the noise we can assume is distributed about 0 with a Gaussian (continuous) or approximately a Binomial (discrete) distribution. On the other hand, time/date are distributed uniformly. You would have a greater variance of seed values from using time/date than by using noise from adc~, and thus, a lesser degree of correlation between instances. I like your idea, because you really get a completely independent random variable--but I would try to convince you that, for a large number of instances, you would see some correlations in the sequences.

Re: [PD] Random - Different seed each time the patch is loaded
One trick that works in patches that have some human interaction: loadbang a timer, then as soon as some human-generated input happens, grab the interval from the timer and use that for a seed. Of course, this is no use for completely automated setups.

Inline GUI elements can slow down a patch, especially when visible. Also, do you really want the CC input to change the size of the font in the [text2d], because that's what it does now ;-) no it sends a 7bit value to be displayed, the font size is the second inlet Besides that, you may want to have a look at your system config. Linux, right? In that case, you should make sure that OpenGL is configured properly, and that you have 3d acceleration enabled, otherwise all the GEM stuff will be done by the CPU which could also slow things down a little or a lot. There's plenty of docs online for whatever distro you are using... ah! since i got dual head installed i had to say good bye to Compiz and friends, and that maybe means no OpenGL.This is due to xinerama not supporting it, probably i ll have to use xrandr with a virtual desktop size on xorg.conf cause life without dual head can be pretty miserable ;) Yet i don understand why this happens only with midi in and not in other situations.. btw i can t find proper infos about how to offset gemwin on a second screen or to have it not showing bars and window frame Tech specs: Dell D410 1,73Ghz 1,25 Mb Fedora Core 8 + CCRMA rt kernel microkontol KORG here we go, this issue with OpenGL has finally pushed me to trash my old Cinerama xorg.conf and go for the newest Xrandr which is just awesome and i have OpenGL on both screens and the patch loads on my external screen and it runs much more smoothly and nicely!! thumbs up !! yet: the response from the MIDI input is not as fast as as i imagined: what does it make it go so slow? Rotating images shouldn t be such a big deal and since i plan to embed this application on a small miniATX computer or similar i wonder what can be done to address this timing issue.. Simone Also, try not to run GEM stuff in the same PD patch as audio stuff (I mentioned this during the workshop). Running separate instances of PD, one for audio and one for GEM, connected with [netsend] objects or OSC, should do the trick. best! d. simone-www.io-lab.org wrote: hi I hope it s fine with top posting but the issue now is drifting off-topic: the patch works as a charm now, thanks again, but (there is always a but) somehow the incoming MIDI messages are slowed down. I tried to monitor the MIDI in and can see how when i turn the rendering on all the MIDI income gets slowed down terribly. Is there any known issue with GEM and MIDI or anything i have to check on my machine? GEM+sending messages from within PD worked flawlessly, CPU is not hogged, jack runs smoothly.

[PD] open / close patch
hi all i have a question i´m trying to open and close one patch with messages. opening it with pd open patch.pd and then the hole path works fine. basiclly the problem comes when i want to close the patch with the message menuclose. it does not close. any idea why it happens? also i´d like to know how to close the hole pd with a message. thanks a lot ___ Pd-list@iem.at mailing list UNSUBSCRIBE and account-management - http://lists.puredata.info/listinfo/pd-list
Re: [PD] open / close patch
Once you open the patch, it has a new name, so to speak. I attached a patch that will close itself.

Yes, it works! many thanks.
just a warning output in my application:
* Imlib2 Developer Warning * :
This program is calling the Imlib call:
imlib_get_text_size();
With the parameter:
font
being NULL. Please fix your program.
See you soon in bcn

Actually, it's not the whiteness of the noise which is important. Whiteness of noise simply means that the samples are not correlated with each other with respect to time. The key is the distribution of a random variable, namely the instantaneous value of the noise at a single point in time. Since the noise values tend to be close to 0, the values are un-evenly distributed. I'm really just pointing to the advantage of using a uniformly distributed random variable for choosing seeds. Of course, now that you have me thinking about it :) , we could transform our distribution for the noise into a uniform distribution, like using the Box-Muller method backwards. ___ Pd-list@iem.at mailing list UNSUBSCRIBE and account-management - http://lists.puredata.info/listinfo/pd-list
