[PD] capture audio
Hello, I'd like to capture little chunks of audio (50 - 300 msec) from the adc~ input into a buffer and playing them back directly in a loop. The idea is to get the impression of freezing the incoming sound. Can anybody give me a hint in how to implement this properly? (Especially about how to avoid clicks when the buffer content is changed.) Many thanks in advance.

[PD] rotating coordinate system
Hello, I need to solve the following problem for different setups of room distributions. Given are x and y values between 0 and 100: 0/100100/100 | | x | | x | 0/0 100/0 I would like to transform the same values mathematically in a way that the result correspond to the coordinate system rotated 45 degrees clockwise: 0/0-0/100 | | x | | x | 100/0 100/100 Hopefully someone can help me with this. Many thanks in advance. Achim ___ Pd-list@iem.at mailing list UNSUBSCRIBE and account-management - http://lists.puredata.info/listinfo/pd-list

Anyway rotating a point is easier if you convert the coordinates to polar coordinates (radius and angle) first, then add the rotation angle to the current angle and convert back. You could do the math yourself, but in Zexy there are some handy abstractions that do it for you: [cart2pol], [pol2cart] convert between cartesian (x,y) and polar (r, phi) coordinates: x y | | [cart2pol] | | | [+ 0.785398] add rotation angle: 0.785398 is 45 degrees converted to rad | | [pol2cart] | | x' y' The phi-angles are specified in rad, not in degrees. If you want to use degree for the rotation angle, the [deg2rad] object is helpful and it's also part of zexy. Or make your own: rad=deg*pi/180 I tried this but without the results I expected. Probably it was not very clear how I explained it. See attached patch for a better description of what I am looking for.

Re: [PD] 8ch diffusion
Hello Frank, thank you very much for your patches. I'll have a look at it very soon. Because of [mtx_mul~] I would like to add iemmatrix to my path list. How can I set a new search path for a library when the folder is inside the PD package (because I can't open the PD Contents from the window that opens.) Thanks for help.

Or is there an even easier (better) way to do the same. I already tried [vbap] but the objects [define_loudspeaker] and [matrix~] are not recognized by my PD-Extended 40.3 on Max OS 10.5. (see other attachment). Attached is a cosine-panner that I built to pan sounds accross a 12x5 speaker matrix [1] (with help by Peter Plessas, thanks again!). If you want to pan to that many outputs, I highly recommend to use the iemmatrix objects, they make things much easier. Never use [matrix~] that object is nameclash-polluted, use [mtx_mul~] instead, an example is in the cospan help file. Anway you can pan with just [*~] as well using [cospan], it's just a lot more patching work, more error prone and slower. The basic idea is to create as many [cospan index channels] objects as you need. Say you want to pan over 4 channels left to right, you create these: [cospan 0 4] [cospan 1 4] [cospan 2 4] [cospan 3 4] and send each of them a position in degrees from 0-360. The left outlet of cospan will output the raw amplitudes of the respective channel, the right one will output messages for [mtx_mul~]. Now if you want two-dimennsional panning, you duplicate the setup for each the vertical or y-axis. See cospan16to9.pd for how I did it for the speaker wall (which is called 16:9 although it only has 12x5 speakers.)

Re: [PD] call for testing on the nightly builds!
I had to switch to a current nightly-build because the pd-extended 0.39.3 is not willing ot work without clicks with jack and my old mbox under os 10.4.8. Compared to the older release all movements and draggings of objects (especially GUI an GOP objects) are clearly slower. When the CPU load exceeds ca. 35-40% on my Powerbook G4 these visual delays are growing increasingly. Is this only the weakness of my computer?
