Hi David,

Is there a help file for freeverb~ under linux? It has 7 inlets, and I'm trying to figure out how to use it.

1. audio inlet
2. audio inlet
3. room size [0-1][values greater than 1 cause feedback!]
4. room damping [0-1]
5. stereo width [0-1]
6. wet gain [0-1]
7. dry gain [0-1]

Win, OSX, Irix binaries available from: http://www.akustische-kunst.org/puredata/freeverb/index.html

Now, can someone tell me where I can get a working copy of the source for freeverb~ so I can compile it for Linux? Olaf used to have a source tarball on the site, but now when I try to compile with the contents of the zip or the tarball that is there now, I get:

make: *** No rule to make target freeverb~.pd_linux', needed bypd_linux'. Stop.

Some things seem to be missing ;-)

best, d.

Hallo, Olaf Matthes hat gesagt: // Olaf Matthes wrote:

freeverb~ uses some C++ features and thus the makefile has to specify a c++ compiler instead of a c compiler. Since I don't have linux I'm not 100% sure how to do that. If someone could provide a working makefile I'd include it in the archive (together with a helpfile ;-)

I'm not sure, if what I have is the current version, but at least the attached archive one does compile on Linux using the modified makefile.

Ciao
