Re: [PD] harddisk recording confusion

You can save the table to hard disk afterwards with soundfiler. Tom On 4/25/05, Niklas Saers <niklas(a)registrar.no> wrote: > > xrecord~ only records to an array, right, not to a file?

Installation with GEM
by Florian Grond 25 Apr '05

25 Apr '05

Dear List, I would like to realize an installation in GEM but I don't know if there are appropriate objects or If I have to teach myself how to program them. If you could give me advise which direction to go I would be very pleased. Two cameras would send their frames to two image stacks which contain say 30 frames (the more the better). The actual frame is subtracted from the last one and the resulting frame of this simple kind of movement-dedection would serve as a parameter to compose from the two stacks the actual video output reading each single pixel in a random manner from the two stacks mixing both by using an appropriate function. Does anyone have an idea how to realize that with existing objects, and if not, where do I find good documentation to learn how to program GEM. Thanks a lot, Florian

audio newbie question LFO
by wolfgang schwarzenbrunner 25 Apr '05

25 Apr '05

hi list... maybe a very stupid question. i want to use an osc (as LFO resp. values under 1hz) giving me controlvalues for a curve object. the thing is, that i want this LFO displayed in a table constantly. well if i use a tabel with little samples (for ex. 100) which works in view of performance the drawn curve is logically very flat (as 1hz spans over 44100 samples). if i make the table holding 44100 samples the whole curve is drawn but i can only update it each second. is there any way to scale the visualization of the curve into an small table... i know -- quiet stupid question... -- but anyway -- help needed regards wolfgang

harddisk recording confusion
by Niklas Saers 25 Apr '05

25 Apr '05

Hi all, writesf~ sfwrite~ sfwrite13~ and possible ogg/mp3 variations thereof... :-) There are quite a few to pick from, and none of these have any outlets. What I need to do is record to harddisk, take a pause and continue. For these pauses I need to make an overview of where the pauses in the recording are. I plan on storing these in an array (other suggestions most welcome :-) ). Also, will I need to worry about conversion to long integers or does PD handle that so that I won't need to worry about the regular floats wrapping? What I'm wondering about is: are there any harddisk recording objects (with or without compression) that will tell me how far they've reached so that I can position myself within the clip for playback of only one recording period? Cheers Nik

Strange problem with vline~
by Carlos Pita 25 Apr '05

25 Apr '05

[ bang ( ------[ 0 0 0, 1 15 0 ( | | | [ vline~ ] | | ------------[ tabwrite~ t ] I have this simple patch above with a [bang( which triggers a couple of messages describing a line segment ranging from 0 to 1 in 15 ms, and at the same time the writing of this segment into table t. Suppose a typical setting with sample rate=44100, table size=1024. If block size is small enough (~64 or less) the patch works ok. But with bigger block sizes the segment appears displaced to the right of the table left border as if its starting time was out of sync. Stranger yet, cause it starts in different positions of the table every time I press the [bang(. As I increment block size the average offset increases too. Is this a expected behaviour of [vline~]? Am I making some mistake? I understand that [vline] schedules its segments at "audio time", in other words that it has sample-precision instead of block-precision. Thank you in advance. Regards, Carlos

Grid: cross-platfrom binaries?
by derek holzer 24 Apr '05

24 Apr '05

I'm trying to get Grid working enough to use in my end-user, cross-platform abstractions such as Particle Chamber, and I've been waiting on Grid for a while now. So, can anyone tell me: Is Grid GoP compliant in all platforms yet? Or, to be more specific, has anyone compiled the latest GoP-compliant Grid for OSX and windoze? Can anyone point me to the binaries of these? I wiould like include these binaries in all future distributions of Particle Chamber and others to make the n00bs lives' easier. thanks, derek -- derek holzer ::: http://www.umatic.nl ---Oblique Strategy # 70: "Feedback recordings into an acoustic situation"

escape character in messages
by Marius Schebella 24 Apr '05

24 Apr '05

Hi, I think this was discussed before (2001, 2002, 2003, 2004, 2005) The handling of some characters in messages is really a pain. for some externals I need to create messages, which should output $0, $1 and so on. of course there are work arounds. but easier would be to have an escape character like $ or whatever. today I needed to produce the character combination \, (backslash followed by a comma). which I needed for dynamical creation of a special object in dyn~. well... shame on me I could not produce it. I donÅ½t want to say I found a solution after all, because, then you might think this problem is not urgent. It would be really a big advantage to have an escape character! ($# or $@ or $* is alsoa neverending story...). thank you. marius.
