[PD] Gem and audio, multiprocessors, Mac
Hi list, Is there a strategy to optimize GEM video processing and real time audio on a single Mac using pd~ : Audio in subprocess or in main process ? Any startup flags ? chmod +s stuff ? shm settings ? Run two instances of PD with messages between them ? Subprocess fifo size ? The idea would be to give a priority to sound versus video, if absolutely necessary. Situation : On a single Mac (pro or mini), Gem (pix_video tracking, ordinary resolution and fps) and real time audio (10 channels, mainly reading from disk), dispatched on four processor cores via pd~. The sound is generated in the subprocess (big latency 512), the video in the main patch. pd-extended 42.5 osX 10.7 10.6, gem 93, 92. Problem : Sound is distorted when Gem is rendering, and becomes immediatly perfect when stopping rendering (destroying the gem window). Processors seem ok (each core at 75%). Sticking with this problem for a couple of months, Looked around in archives but didn't find any clear element.

Re: [PD] Gem and audio, multiprocessors, Mac
Hi Jean, there was actually a discussion few days ago here, about the [pd~] and optimization topic. However, for audiovisual processes, apparently it's still more reliable to use two different instances of Pd. One proceses the sound and the other the video. The video Pd instance might gain some more cpu resources when launched with the flag -noaudio. Then you want to exchange data between patches on a local network on your machine using [netsend] and [netreceive]. AFAIK, the main feature of [pd~] is to keep synced processes happening in different threads. Thus, when one of the processes slows down, the others slow down too. Which, can be good for audio projects, but audio and video patches won't work really well due to this feature. cheers, Marco Is there a strategy to optimize GEM video processing and real time audio on a single Mac using pd~ : Audio in subprocess or in main process ?

Re: [PD] Gem and audio, multiprocessors, Mac
i tried both, audio definetly must be in the main process, not the pd~ process. see those patches where various techniques are described: http://www.uni-weimar.de/medien/wiki/Audiovideo m.

[PD] [spectrogram~] won't show anything
Hello, I noticed that the object [spectrogram~] won't show anything in the array in my pd-extended. I'm using ubuntu 11.10 with pd-extended installed from the apt repository http://apt.puredata.info/auto-build/2011-12-07/ which seems the only place where I can find a compiled package. In the system's official package puredata the object works fine. I opened [spectrogram~] and using the [print~] object I noticed that [sqrt~] outputs only zeros, and the multiplications above shows some non-zero results. ___ Pd-list@iem.at mailing list UNSUBSCRIBE and account-management - http://lists.puredata.info/listinfo/pd-list
