hello I need to use Max/MSP for a concert (Pd won't be installed on the computer there), so if I want to play anything I have to port some of my Pd patches to Max/MSP is the Max/MSP object [%~ 1.] an equivalent to the Pd object [wrap~] ? thanks a lot j PS : for Pd users who want to use some Max objects, there are some libraries like Cyclone or MaxLib Is there a library of missing Pd-objects for Max/MSP too ? --

RE: [PD] Waveform Analysis?
by Ian Smith-Heisters 15 Apr '04

15 Apr '04

I read a story a while back (may have been a year or two) on arstechnica that some guys developed a new system of organizing music using compression. When you compress a file (in this case a song) the compression algorithm looks for similarities within it. It turns out that in exploiting the similarites in the file to get smaller filesize, songs with similar genres share characteristics in their compressed form. eg. if you compress a whole bunch of Wagner, the compression algorithm will be looking for repetitions in the data, which traslates to compositional style, in this case trumpets blaring, extreme dynamics etc. So all compressed Wagner will have some similarity in the resulting file. I forget what the similarities were. In fact (as you can see) I forget most of the article. I tried to find it again with no luck. But that may not be what you're looking for. For general analysis I'd try looking for beats with the usual methods, maybe try a discrete cosine transform to look for patterns of harmonics... I'm not really sure. Then you need to deal with how to analyze all that, which depends on what you're trying to do. There are certainly genetic algorithms written that recognize stylistic similarities in music, and probably some implementation of neural nets that do similar things. As far as being able to get those, I think they're all pretty specific implementations and probably unavailable anyway, so you'd have to write it from scratch. I'd guess if you're trying to do a whole lot of this that it's not a problem for Pure Data, as you won't be doing it in realtime. You could start by looking for C libraries that do functions on audio files. -Ian > -------- Original Message -------- > Subject: [PD] Waveform Analysis? > From: "Ju'k J'unk" <jukjunk(a)hotmail.com> > Date: Wed, April 14, 2004 11:37 am > To: PD-list(a)iem.kug.ac.at > > Hey Everyone, > > Would anyone know the approach to take to do an in-depth analysis of > waveforms or waveforms of an entire audio track?

adding IEM lib to the CVS
by Hans-Christoph Steiner 15 Apr '04

15 Apr '04

So it seems that Thomas Musil does not want to add IEMlib to the CVS, or perhaps does not have time. So I was thinking of importing the code into CVS and maintaining a devel branch there. Any objections? .hc ________________________________________________________________________ ____ "Information wants to be free." -Stewart Brand

Hi, Just realised I put the wrong library in the title of my query! I was wondering if there is a function that enables tallying of values within a matrix. Thanks Alyte

Re: pd newbee [MS Notepad]
by Michael Berkowski 15 Apr '04

Hello, when you save the file in notepad, choose "All files" from the Save as Type drop down menu at the bottom. Then you can save as filename.pd. To make things a little easier to see, you may want to uncheck the box labeled "Hide file extensions for known file types" in the Folder Options control panel. This way, you can easily see which files are *.txt and simply rename them to *.pd good luck Michael http://www.berkowski.net/ michael(a)berkowski.net/ > well, i use winxps notepad... it saves it only as a .txt file and PD cant > see it. what should i do? > > thanx in advance >
