audio fingerprints
by David Sabine 29 Nov '02

29 Nov '02

Hello all, I'm wondering if anybody has explored the process of creating and retrieving audio "fingerprints". My experience with such a process is very limited, so please forgive me if my jargon is un-informed. What I'm interested in is simple: 1. record a sound. 2. generate a "fingerprint" - perhaps based on peak frequencies, wave shapes, etc.? 3. test that fingerprint against a database/collection of other fingerprints 4. return a value dependent on whether or not a match was found and perhaps a value (percentage?) representing how reliable the 'match' would be. I've taken a look at [choice] in the "extra" folder but it doesn't seem immediately applicable to this project. ? Perhaps I'm misunderstanding this object and its usage.? The eventual goal would be to record a performance or excerpt of a performance and be able to determine which song is being played. Many thanks, Dave S

Convert float to string and appending two strings
by Jordan J 28 Nov '02

28 Nov '02

Hello, After searching through helpfiles and the pd-list archive I couldn't find a solution to my problem, which is this: Say I have a float "5" and a string "cat". How would I append these two to make a new string "cat5"? I could have missed something gravely important in the documentation or maybe I just used the wrong search terms for the pd-list archive. Any help would be appreciated. Thanks. -Jordan

Re: [PD] laptop + linux + pd + help the radeon is well supported for hw accelleration under the DRI [dri.sf.net]. i get unusually high frame rates in quake3arena... oh, and GEM also runs beautifully ;) the only disappointing thing about the dell insprions /latitudes are the maestro3i cards; they masquerade as a full duplex card [according to the bios] have too much line noise and have a frigid mic [at least on mine]. aside from the prehistoric problem of the ACPI vs change of power state hairiness [common to many brands of laptop] the dell's are *solid and reliable powerstations with oodles of features.

Audio I/O stuck, win2kpro
by Martin Dupras 28 Nov '02

28 Nov '02

Hi, I'm having the dreaded "audio I/O stuck" problem for the first time. I've searched the archives to try to find a quick fix, but it seems to be a recurring problem with no obvious solution. Is that the case? I've got the problem running on two machines: my production machine (which has a hammerfall9652, no problem until today) and a brand new Compaq laptop. The problem happens in both cases. On the production machine, I've added some -path and -lib flags to my the .bat file that launches pd. I'm not quite sure yet which external or library is actually causing the problem (it may take a while to troubleshoot, having to restart each time.) After the audio gets stuck, even if I restart, just launching pd.exe on its own gets "audio I/O stuck", which I don't understand. What does I/O stuck mean? Does that mean the drivers are hogged by some other application? Or do I have a bogus 'lock' file somewhere that makes windows think the driver is in use? Which raises the question: is there a way to explicitly free the driver right before launching pd? Thanks! - martin

pd + dsp2000 c-port + asio
by j. misra 28 Nov '02

28 Nov '02

I'm having nothing but trouble trying to get this to work, with any number of channels. Using the normal MME driver works alright (obviously only if the channels i selected are set to MME) but if I try to use ASIO I get no audio and depending on which device i pick with -sounddev my computer either locks up or PD lags. Does anyone have any experience setting this up? I'm running Windows XP.

laptop + linux + pd + help
by Rama 27 Nov '02

27 Nov '02

Hi buddies ! Maybe I should not post this into this list, but I'm getting crazy tryng to decide which laptop to buy in order to get (debian) linux and pd working perfectly. If someone could give any kind of help about it I would appreciate it very much. Of course one of my main needs is to have linux working with all of the system devices (net, usb, X + accel/OpenGL(to use GEM)) and definetely PD. One possible target is a Dell Latitude (Dell says they support linux for this line of laptops and it is supposed that everything should work under linux with those, but I'd like to confirm some way (if possible), that it's true and that I won't be fighting against it (and them) in order to have everything up and running. The video card might be an Ati Mobility Radeon 7500 or 9000 (i beleive) but I understand acceleration is not yet supported under linux for this cards, so the alternative is an nVidia w/64mb which seems to work (also would like to confirm). I'm sorry if this message bothers someone out there but I really need some help about it and I guess it might be of help for other users (probably). If someone could recommend me any kind of solution (even posting this at any other list or whatever) I will be very happy. If direct help could be provided it would be great ! Any feedback welcome ! Thank you, guys. cya Rama.

bitmap sequencer and flext png library wrapper
by Robert Figura 27 Nov '02

27 Nov '02

Hi some, I watched the thread about trackers and pd and since i still had not found a sequencer software to fit my needs (shaketracker won't compile, jazz is not quite what i want) i decided to use bitmaps for sequenceing. My favorite mapping is like this: (using hsv conversion) x->freq y->bar h->waveshape-index s->intensity v->velocity A=aux-param As i somehow missed gridflow until now, i wrote a little png library wrapper using flext. Now gridflow is just too nice but if anyone is still interested in these 400 lines of code, just email me a note and i will put it online somewhere. It can read 8 or 16-bit CLUT-mapped, RGB, RGBA, Grayscale, Grayscale+A png files. Until now it can not write files or modify a loaded bitmap. It was implemented on a linux box so porting is untested but IMO should be trivial. I just started using gridflow so i may decide to continue developing pngread later. BTW: I would like to implement flext-threads, but how? Am i yet again missing the flext docs or aren't there any beyond the source? Why do the flext tutorial makefiles have references to thread examples but i cannot find them? Happy patching - Robert Figura -- /* mandlsig.c v0.23 (c) by Robert Figura <rfigura(a)metabit.com> */ I=1702;float O,o,i;main(l){for(;I--;putchar("oO .,\nm>cot.bitamea\ @urigrf <raguFit erobR"[I%74?I>837&874>I?I^833:l%5:5]))for(O=o=l= 0;O*O+o*o<(16^l++);o=2*O*o+I/74/11.-1,O=i)i=O*O-o*o+I%74*.04-2.2;}

open textfiles
by marius schebella 27 Nov '02

27 Nov '02

hi list, i would like to add some comments to my patches, which I would like to save in seperate textfiles. it seems to be possible to open textfiles in tcl-tk/Pd. if i use the menu-item "help" - "Pure documentation" i have the chance to open pd-files and also text-files, which appear in an extra-window. so i think there should be a message-command to open any textfile in a pop-up window... any ideas? marius.
