I specifically use it +for resynthesizing sinusoidal tracks in pd... look for Trax on my +webpage to get all the components for that. + +INSTALL: +You first need to download and install Ircam's SDIF library. There are +many different versions to be found on the net, I am using the latest +Sourceforge version found at http://sourceforge.net/projects/sdif. Last +time I tried, I could not get it to compile on windows, so if you want this +on that platform you have to get it to compile and adjust the makefile. + +in this directory do + (for linux) + make pd_linux +or (for mac) + make pd_darwin + +HOW TO USE: +[sdiflists] will only handle one stream per sdif file; if you do not declare +which stream you want you will get the first in the file by default. All +matrices within that frame will be available for output. The number of +outlets is declared as an argument to the externals, e.g. [sdiflists 6] +would make 6 outlets that output analysis data, one for each column. +So if you have 2 matrices of 4 columns each, you will get all of the first +matrix and the first 2 columns of the second. There is also an outlet +for time and for info such as 1NVT tables and other useful things. +For syntax detais, see sdiflists-help.pd. + +BUGS or SUGGESTIONS: +There are a couple known bugs (you may notice warnings of the +wrong frametype in the terminal, haven't figured out why yet) and +a couple work-arounds in the code. But please let me know what +you find when using this external, if you can fix it then great. As I +mentioned above, so far I only use this external for sinusoidal +synthesis so I do not know if frametypes other than 1TRC or +1STF will cause problems. I have tried to check, but.. you know. + +TODO: +- make an external for writing sdif files.. hopefully people have +suggestions for doing this because it is a little trickier than +outputting lists like [sdiflists] + +THANKYOUS: +Thanks to Tom Erbe for all the programming tips throughout my +stay at UCSD. Thanks to Miller Puckette for helping me figure +out the odds and ends of Pd. Thanks to Shlomo Dubnov for +introducing me to and sharing knowledge about Sound Descr- +tors. Finally thanks to those on the SDIF and Pd mailing lists +for helping cure me of ignorance. Sorry though, still a long way +to go!
