HDSP: OSS emulation depends on sync mode
by plessas＠sbox.tugraz.at 11 Nov '04

11 Nov '04

Dear Members of pd-list, here is sth that looks strange to me: i have a debian testing system with an hdsp pci card. when i have the card in auto_sync mode (i.e. it accepts any digital clock at any input as master clock) and it receives 44.1kHz clock from my mixer via Adat-IN, pd refuses to open audio: error: OSS: SNDCTL_DSP_CHANNELS failed /dev/dsp but when i put the card into 44.1kHz master mode, so that it ignores any incoming clock, pd runs fine with oss emulation and 18 channels! i would prefer to have the card in slave sync mode. has anyone had the same? prost, Peter

Re: [PD] perception of sound

search the web for the fletcher-munson-curve. it shows the perceived sound level for different frequencies at the same level. a sine tone at around 4khz is perceived loudest. sven. >This is the first time I get involved in the Pure Data mailing list, a >kind of newbie then and I'm currently facing to a problem for which I have >no competences : I've got a buzzer which aims at producing a sound >sequence when a certain default occurs.

Gem crash [alpha]
by plessas＠sbox.tugraz.at 11 Nov '04

Dear List Members, have a strange crash when opening the (new, beatiful) help file for [alpha], just as i start rendering, pd crashes: pd: ../../../../src/tnl/t_imm_api.c:335: _tnl_end: Assertion `ctx->Driver.NeedFlush & 0x1' failed. Pd: signal 6 this also happens when i create the same patch in a new window, this is on debian testing running pd-0.37-1 and Gem-0.90 any sggst. apprctd. :) Peter

Linux migration
by beau25＠access4less.net 10 Nov '04

10 Nov '04

Hello PD list, A week ago I wrote about pd not finding libtcl.so.0 or libtk.so.0 Well pd still can not find these libraries, but I have managed to find them in my usr/lib folder. This makes me think that the pd rpm needs to be in a specific location inorder to find these libs. Does any one know what directory the pd.rpm file should be placed in for a linux installation of the program? Also the libtcl.so file is missing the last 0 do you think that should make a difference? I am on redhat 9 incase you need to know this inorder to answer my question. Is there anything else that I need to do to the rpm besides double clicking on it to get it to install correctly? Would trying the tar.gz be any easier?

pdp mac os X
by Gonzague DDR 10 Nov '04

10 Nov '04

Hi list , I ve just installed pd 0.37.0 on a mac osX , and i never touch a mac before . I have little trouble with gem : all seams to work very well ( loading gem , creating gem objects , video_pix is working ), but the [gemmouse] do not return any value ...? An other thing is that , when i run pd -lib pdp ,it find pdp.pd-darwin , but crash saying : dyld: /usr/local/bin/pd can't open library: /sw/lib/libgsl.0.dylib (No such file or directory, errno = 2) Do someone have an idea ? thanks 3o3 ===== http://cypres.dyndns.org:40020/ Vous manquez dÂespace pour stocker vos mails ?

readsf~ / soundfiler crash with lots of big files
by Stefan Turner 10 Nov '04

10 Nov '04

Hi list I'm trying to make a piano sample player using a CD I just got. I have a 'voice' abstraction per pitch and therefore per sample file, which has a table of the first 4096 samples preloaded with a loadbanged readsf~. The readsf~ and tabwrite~ are stopped and the patch switch~ed off when the table is loaded. This table is played immediately when the note is hit to cover the gap between 'open' and '1' to the main readsf~, which then plays the rest of the original file from 4096 on. It works fine with a few voices, but when I try to have about 12 voices (covering one whole octave!) pd crashes as soon as it opens and won't behave until I restart the computer. I guess this is because the sound files being loaded are quite large (up to 5MB)? With the table-preloading removed, it doesn't crash. So basically is there any way around this? I've tried soundfiler as well, and the same thing happens. Do both these objects try to load the whole file into memory even if you tell it to stop after 4096 samples? Sorry about the length of this, it's fairly tricky to describe. If anyone has any ideas I'd be grateful! Stefan Turner ___________________________________________________________ Moving house?

Re: [PD] Re: [PD-dev] Re: prepend w/ set message - ignore
by Stefan Turner 10 Nov '04

Yes, what about a completely new 'prepend' (called something else), with an additional inlet for 'setting'. This would be the best of both worlds AND avoid name collisions.

Thanks for your support ! Your explanations are clear (I did not think in term of energy carried by the signal but eventually it seems so obvious... let's go for a first start with a square wave) ("ça tombe sous le sens !") and I'll have a look at the links you gave me (PD beginner, I have to get involved in audio processing as well). As for the word "buzzer", we use it to design, yes CK, a big flashy button that you squeeze the more violently you can or... a little loudspeaker. I was talking about the little loudspeaker. At least, it seems that using a "foreigner word" in your native tongue is as hazardous than exporting a .pat to a .pd...
