filter transfer function
by Rich E 06 Feb '06

06 Feb '06

Hello all, My instructor at school is trying to make a patch that will graph a transfer function in real time, but it doesn't seem to be working out with Pd's built in arrays. I was thinking that he might be able to do it with Gem, but on second look I don't see any easy way to do this either. Does anyone know of a good way to graph an out audio signal against an in audio signal (one would be x, one y)? Thanks if anyone can help, Richie

compile on ubuntu (again)

Yes, XMMS is working fine. Actually, I'm not getting any sound from Alsaplayer, though XMMS is supposedly using the XMMS-JACK driver. The output I pasted is from qjackctl with verbose turned on, though when I run jackd I get the same output. I've tried messing around with various Jack settings, but nothing seems to make any difference. What's puzzling is that it appears to be working until it says "Could not connect to JACK server as client". Could it have something to do with Alsa not being configured properly? I'm sure this is typical of the Linux world, but there seems to be a lot of obsolete information that comes up on Google searches. It would be nice if things came down after a few years... for instance, the mini Alsa HOWTO posted on the alsa wiki site alsa.opensrc.org is from 1999... I think probably a lot has changed in the last 7 years! I would like to contribute some time to keeping these things up to date, but I don't feel that I have the expertise just yet. Certainly once I can reimage a low-latency machine with jack & alsa working right away I'm going to be paying back for all the help I've received over the years!

Hello everyone! Sorry to be a drag here, but I've been scratching my head on this for several days now. I'm trying to coordinate pd, alsa, and jack on ubuntu (actually demudi multimedia kernel 2.6.12 in ubuntu) and I've got a number of symptoms here, but I've not been able to diagnose what's going on: - not getting any sound from pd; pd doesn't recognize any devices - pd's Media menu lists 'OSS', 'ALSA', and 'Jack' - compiled pd 0.39-2 with --enable-alsa --enable-jack - alsa seems to be installed fine, alsamixer works, cds play in alsaplayer - qjackctl will not connect to jack server as client - but jack appears to start fine (?): 13:44:26.950 JACK was started with PID=6255 (0x186f). jackd 0.100.9 Copyright 2001-2005 Paul Davis and others. jackd comes with ABSOLUTELY NO WARRANTY This is free software, and you are welcome to redistribute it under certain conditions; see the file COPYING for details JACK compiled with System V SHM support. loading driver .. apparent rate = 48000 creating alsa driver ... hw:0|hw:0|1024|2|48000|2|2|nomon|swmeter|-|32bit control device hw:0 configuring for 48000Hz, period = 1024 frames, buffer = 2 periods Note: audio device hw:0 doesn't support a 32bit sample format so JACK will try a 24bit format instead Note: audio device hw:0 doesn't support a 24bit sample format so JACK will try a 16bit format instead nperiods = 2 for capture nperiods = 2 for playback 13:44:29.002 Could not connect to JACK server as client. 13:44:31.629 JACK is stopping...

freeverb~
by Davide Morelli 06 Feb '06

06 Feb '06

Hi! trying to compile freeverb~ with msvc (VCToollKit) i got errors because of the use of "inline" adding this to the beginning of the file solved the problem: #ifndef INLINE #if defined(_MSC_VER) #define inline __inline #elif defined(__GNUC__) #define inline __inline__ #elif defined(__MWERKS__) #define inline inline #endif /* defined(<Compiler>) */ #endif /* INLINE */ should I commit it? it is also missing a simple makefile, i've just wrote one, should i commit it too? ciao, davide.

dealing with arguments and inlets
by Hans-Christoph Steiner 05 Feb '06

05 Feb '06

I have written some classes for handling arguments when writing classes in Pd. They are [float_argument], [symbol_argument], and [any_argument]. Currently, I am thinking in general, inlets should be matched to arguments and vice versa, so these objects all have a "convenience" right inlet, to attach the [inlet] to so that the data all comes from the [*_argument] object. To use them, you add the argument you want it to handle like this: [float_argument $1] If you want a default value for when none is specified, you would do it like this: [float_argument $2 234] [symbol_argument $3 default] [any_argument $9 asdf] [any_argument $5 444] My goal is to make these a standard way of handling arguments when writing classes in Pd. What do y'all think? Also, I am trying to think of a library name in which these would belong. foundation? support? core? patching? language? .hc ________________________________________________________________________ ____ "If nature has made any one thing less susceptible than all others of exclusive property, it is the action of the thinking power called an idea, which an individual may exclusively possess as long as he keeps it to himself; but the moment it is divulged, it forces itself into the possession of everyone, and the receiver cannot dispossess himself of it." - Thomas Jefferson

Hi, Does anyone know of a good place to download some PDP patches? I've been messing around with PDP and PiDiP for a little while and I'd like to see what other people have done. Thanks -- Steve

What do y'all think? This is a very cool idea. Virtually all my abstractions have an inlet and ii (from iem) for each argument: would definitely be better to have both in one. Might it be better to go all the way and have these as externals which function as [inlet], but also support defaults as you've said? Obviously then it would be cool to keep the naming argument of [inlet], which appears when you hover. Or alternatively to extend the built-in inlet to give the functionality you've said, while just behaving as currently if the extra arguments aren't given, e.g.: [inlet] - as current [inlet name] - as current, with a name [inlet name $1] - as current, but at loadbang-time output $1 [inlet name $1 123] - as current, but at loadbang-time output $1, or 123 if $1 not specified Don't know how you'd handle the separation of floats, symbols and anys then though...maybe add finlet and sinlet...??

limited size of pd-arrays
by Christoph Sladeczek 04 Feb '06

hallo, i have a problem with the size of the pd-array. i use it to preload wave-files, which will be played by tabplay~. i need to preload the files because of the latency of readsf~. the array is limited to 4000000 samples. is there a possibility to extend this size? thank you,best regards christoph
