some of the .HTM files in the excellent html documentation is not found by my browser as I am on a case-sensitive unix filesystem. I had to convert the uppercase .HTM filenames to lowercase to make it work.
This should be done to the docs in one of the next releases perhaps. Let me know if/how I can help.

You are right: The following computer music software projects use a mailing list (+archive) as their primary means of communication:
CSound: http://csound.1045644.n5.nabble.com/mailing_list/MailingListOptions.jtp?forum=1093014
Pure Data: https://lists.puredata.info/listinfo/pd-list
SoX: https://lists.sourceforge.net/lists/listinfo/sox-users
IRCAM runs multiples: http://listes.ircam.fr/sympa
GNU Octave: https://lists.gnu.org/mailman/listinfo/help-octave

Please do not start a facebook group. Vote on this thread. It has an option for voting for Facebook. If you want to help, let us know here and you could for example become a mailing list admin (low volume).

Dear Mr. Rutz,

does the output file exist already perhaps? CDP does not overwrite output files.

Hi uuuuv,

That's pretty much what I do. I take the comprehensive list of the programs and their modi from SpiralDeskRefContentsR7.pdf and SpiralDeskRefR7.pdf. Usage is explained on the shell itself as mentioned before. Fun starts once you put them into shell scripts of course, which is my number one motivation to use CDP on the shell only.
It makes sense to try to relate some program+modi to the illustrations in the Audible Design appendix, eg. the waveset/wavecycle transformations and to take notes of programs that you already used successfully to better remember in a month from now.

Oh, and I do prefix all CDP binaries on my system with cdp_ to better differentiate them from other unix binaries. I put them all inside a folder called ~/bin/cdpl and then in ~/bin I run
       for a in cdpl/*; do ln -s "$a" cdp_"`basename $a`"; done
to get symlinks to the actual binaries which are all prefixed with cdp_ eg. cdp_distort

I had your error regarding Audacity before, and in my case it helped to start Audacity setting an environment variable before starting it:
LD_LIBRARY_PATH=/usr/lib/x86_64-linux-gnu/ audacity
which I have in a shell alias as
       alias audacity='LD_LIBRARY_PATH=/usr/lib/x86_64-linux-gnu/ audacity'
For all questions regarding general Linux audio question I recommend you ask on the Linux Audio mailing list http://lists.linuxaudio.org/listinfo/

Hi uuuuv,

instead of an IRC I would like to have a proper mailing list over a web forum for communication. I would have replied much earlier if I could have had done it by simple email.

On which operating system are you on?

I find that executing the individual commands from the shell without arguments gives you already a quite clear idea of their useage, different modes and parameters. So in my case I would do something like

analysis of wave file into spectral file
$ pvoc anal 1 infile.wav infile.ana

spectral blurring operation in its 'blur' mode over 16 windows
$ blur blur infile.ana outfile.ana 16

listen to the result (optionally)
$ pvplay outfile.ana

convert to time domain
$ pvoc synth outfile.ana outfile.wav

This syntax can be derived from the useage information the individual programs give you on the shell.

Hi Simon,

Trying to unzip the file I am getting the below error message. Is anyone capable of unzipping it?
I am on Debian. Thank you! Peter
