[Audacity-devel] Progress Report

[Warren K. <pr...@gm...>]

Hello Folks,

As I mentioned earlier, I am interested in experimenting with the effects
programs in Audacity, reverb in particular. Here is what I have done so far:


   - Converted my old Toshiba Satellite A75 to a (Ubuntu) Linux machine,
   completely removing Windows XP. Runs like new except that it overheats and
   shuts down during CPU-intensive processing. I will have a local tech clean
   the fans and heat sink and hope that helps.
   - Downloaded source code for the current Audacity release and also
   downloaded all the libraries so that ./configure runs with no errors.
   - Tried to run make, but have not yet succeeded due to the overheating
   problem mentioned above. It leaves a bunch of partial .o files in its wake
   and I have to run 'make clean' and start over.
   - Found the current reverb code in reverb.cpp, reverb.h and
   reverb_libsox.h. The real "beef" seems to be in libsox.h - I recognize the
   freeverb algorithm with its comb and all-pass filters. I am surprised to
   find function definitions in a header file - I was raised to believe that
   only declarations. #DEFINEs and such belong in header files. Why are the
   function definitions here and not in a .c or .cpp file?

Anyway, I am beginning to see how a version using a different reverb
algorithm can be constructed. My weakest point is my almost complete lack
of knowledge about GUIs, widgets, etc. but once I know where the data is, I
am reasonably comfortable.

Regards,

Warren
