The Eternal Return of Resynching Audio
by Elliot Anderson 03 Sep '99

03 Sep '99

I took Mark Danks' advice and put a return in the routine nt_resyncaudio(void) in s_nt.c. This seems to have solved the problem. Pd seems to be working fine on both my notebook and desktop. Some questions. I'm somewhat of a "newbie" to computer music and was wondering if anyone could suggest a "primer" on signal processing. I listen to a lot of electronic music, Xenakis, Sabotnik, et. al. and know people in the Bay Area that are part of The Hub (Tim Perkis, Paul Demarinas.) I am interested in doing real-time composition and to trigger video (thus PD & GEM.) PD questions. What format should the aiff files be to open in PD? How can I save a sample? What are the ";" objects, like the one that starts the DSP and opening files? What is the syntax for those objects? Can I send a signal through and process it in real-time using a mic? I've done this with MSP and haven't tried it with PD. Best, Elliot Elliot Anderson Lecturer, Electronic Media, Art Department University of California, Santa Cruz http://www.sirius.com/~ewanders

pd sounds great-while mouse is moving
by Klien V 03 Sep '99

03 Sep '99

hi, we're trying to make pd run on a pc/redhat6.0, ISA-soundblaster64, Alsa-driver. it's not duplex, which would be fine, but the audio-output of pd stutters. everything sounds fine while moving the mouse.->? already changed the mouse-driver - no effect. anybody experienced something similar? volkmar ****************************************** Volkmar Klien City University London e-mail: v.klien(a)city.ac.uk ******************************************

Re: re-compiling & resynching audio error

>It seems that the "resynching audio" problem is not confined to the SB Live driver. I installed PD under W98 on my notebook that has an ESS sound card and had the same problem. Yuck. OK, I'd better make some kind of flag thing. I can probably get it out this weekend... >Finally, is there a way in PD to read the parallel and serial ports? There isn't yet. There's a hack to write to the serial ports that uses TK's serial command; I don't know if it would be easy or not to do input the same way; timing wouldn't be too great though. It would be great to have "externs" to handle serial and parallel ports... I don't have any serial or parallel devices to test them on. cheers Miller PS Oh yes, to compile in Microsoft C version 5.0, remove all the ".obj" files, change the include and library paths in the makefile, and it should go.

I'm There is a serial object, but I think that it is pretty hackish...Miller can probably give better info.

re-compiling & resynching audio error
by Elliot Anderson 02 Sep '99

02 Sep '99

It seems that the "resynching audio" problem is not confined to the SB Live driver. I installed PD under W98 on my notebook that has an ESS sound card and had the same problem. I tried recompiling PD using the included makefile and nmake from Microsoft Visual Studio 5. I got errors when it tried to compile. How should I re-compile? Finally, is there a way in PD to read the parallel and serial ports? I'm trying to find an easier and quicker development tool to do interactive installations. Right now I develop my work in C/C++. I mostly use the parallel port for interactive devices, i.e. sonar sensors. I then play wav files in synch with a laser disc in response to input. The laser disc player is attached to the serial port and I've talked to it using PD. I need to read-back from the serial port to see if the laser disc has completed its code.

RE: resynching audio error

As mentioned in a following reply, it seems to have something to do with the SBLive. I have the exact same problem under WinNT. However, there is an easy solution...if you have a compiler. Just go to s_nt.c and look for the function nt_resyncaudio(void). Immediately return and don't do anything. This solved the problem for me. I just did a performance a couple of weeks ago with an SBLive and had Pd w/ audio and Pd w/ GEM on the same box (dual processor). It ran great with around 250 ~ objects (using some switches as well).

gem-0.81 for linux
by Guenter Geiger 01 Sep '99

01 Sep '99

I've put together pd-0.81 for Linux ftp://iem.mhsg.ac.at/gige/gem (Always trying to change locations :) The build process is a little bit reworked, you have to put m_pd.h (from pd-0.26/src into the gem-0.81/src/Base directory). Actually what I'm doing is installing m_pd.h in /usr/include or /usr/local/include, so I can develop my externals. Good luck Guenter

Sv: resynching audio error
by Søren Bovbjerg 01 Sep '99

HI >I just re-installed PD 0.25 under W98 and keep getting a "resynching audio" >error. Running a P333 with SB Live sound card. What should I be doing? First, keep in mind, that PD is designed to run under Windows NT. However it will also work under win95/98. I have a similar soundcard and get the same error under 98. However it helps a lot to disable either DAC or ADC (pd -nodac / - noadc), but I do not consider that a satisfying solution. I don't think that PD is the problem, but rather the Live drivers. It is too bad, because it is a great soundcard for other purposes. By the way, running PD in linux with the Live drivers crashes the soundmodule and keeps PD hanging as a zombie. Running as root crashes the OS (!). Beware! I have reported the problem to Creative. Cheers Soeren
