[Stk] Re: frequency analyzer for stk library

[Gary Scavone]

Hi Jean Marc,

As far as I know, no one has developed an fft-based class in STK yet 
... it would be a great contribution!

If you're going to do this, you might look at the fftw package, which
has very efficient fft routines.  I would envision fft and ifft
wrapper classes on the fftw routines and then perhaps your frequency
analyzer as a separate class?

The next release of STK will happen shortly, but I don't see how any 
of the additions would impact on your work.  Here's a list of the 
changes in the next release:

- osx and windows asio support added
- several RtAudio fixes and improvements
- added nextOut() method to Delay classes
- documentation fixes for Reverb classes
- RAWWAVE_PATH changed to include the "rawwave" directory
- "configure" support added for unix systems
- sample rate flag added as command line option to example programs
- socket port number added as command line option to example programs
- added Voicer, SingWave, and VoicForm classes
- new whistle class
- improvements to the banded waveguide instruments
