first i want to apologize to cross-post like that but i haven't found a way to change the name of the thread.
so ive made some reports on structures , i hope it will be usefull....
as said in the title i apologize cause it's in french . But if people found it revelant , someone will translate it huh?

an accident doing some tests on fft.
it's quite totally hazardous
could you tell which os ,card, platforme , distro you use ?
i use pd ,37 test10 under win2000 sp4 (but it perform perfectly on xp sp1 too on my computer)
i use zexylib,maxlib,iemlib.
i use mmio mode for best latency (i know it's sound really strange but it perform Much better than asio on my gig.)
my card is a rme hdsp9632 with a buffersize of 1,5 (1,415...) ms. (64 block)
whatever value i set on audiobuf or block it stay at 1,5...
i ve made a patch using pd as an effect (decoding live a LtRt movie mix to LCRS (surround))
it was performing quite good in sync with the screen. (indeed one video image is 40ms lenth so with a 1,5ms latency that's ok)
but i heard about the jack low latency driver . id like to know opinion from linux users....
anyway , i should already been on linux but since ive bought that new card , i don't manage to have sound with it , before it was ok with my motherboard chipset AC97 (working huh ) and as far as i remember , it had never crashed under linux against 2 or three times the day with windows, and the cpu consumption was really lower than under zindaube. something like 25 to 40 % less (using windows performance and top on linux .) i understand that this difference come from the graphical management of tck .
what about tabread4- and tabread4-?
i ve troubles when i fill an array with long samples (more than 1 minute)
when i play it i get a decent sound for 10second. after the sound sounds more & more like a bad clocked digital device (that specific bell sound ...) . it is not dependant of the time but of the table : if i put an offset , and start to play say at 10second in the file , the sound get bad immedatly (i mean it's not a vector or vector size problems, sfplay works perfectly...)
i v'ent found anything revelant about that on the pdmailing list
anyone have an idea ?
but found all necessary files for understanding of structures in the folder stuff/structures.
i said that cause regular help for append , get , set , scalar.... are useless : in all that examples objects are already created and it's difficult to see the relationships. Waste weeks triyng to find theses relationships...
after reading stuff you can easily define structures , soething really badly documented but really amzing (powerfuuuullllllll) and in fact ... really simple
of course you can use many ins and outs in pd , depending on your hardware.
but are you sure you wanna go to a usb card? you should prefer a firewire card or even a pci card. for stability, latency ...
for puredata you can't have a defined 5.1 card. you can have 6outs but you have to manage everything about the audio routing.
sometimes it doesn't work cause you haven't made any change in the patch,hence hte file isn't updated.
what i do in such case : control A to select everything, i press the up arrow . everything move from 1 pixel . and i can save it .
stupid tricks but it seems to work.... a least on my version . (pd 0.37.10 on winxp.)
