-
-
-To run oggread~ place the file oggread~.dll for win or oggread~.pd_linux
-in the directory of our patch or start pd with '-lib oggread~' flag.
-
-To compile oggread~ on Linux get the ogg/vorbice library from
-http://www.vorbis.com/.
-You have to modify the makefile to make it point to the place where the
-ogg/vorbis library is.
