 Title: audio signal acquisition from radio control transmitter
 Authors:
  Joel Lienard
  Lionel Cailler
 
 Purpose:  Audio signal acquisition from radio control transmitter.
  This code is based on origianl  Joel Lienard source code modified to support a
  portable library to a wide list of operating systems : http://www.portaudio.com

 It's free, it works, enjoy.  This  is an open source project, so if you  don't
 like the way something works, help us fix it!

 It needs to be enabled (at compile time) by editing crrc_config.h.

 audio_rc.h  audio_rc.c are the required files.
 http://www.portaudio.com library shall be used.
 rc_test.c is a test file to display acquired channel values.
 
 *****************************************************************************

 This is how I tried it (using linux):
  I downloaded version 18.1 of portaudio. In the main directory I called
    make -f Makefile.linux sharedlib
  As root:
    cp pa_unix_oss/libportaudio.so /usr/lib/
    ldconfig
  
  In the makefile for crrcsim, add:
    -lportaudio
  to CRRC_LINKER_FLAGS. It is already there, but must be uncommented.
  
  Set 
    #define COMPILE_AUDIO_INTERFACE 1
  in crrc_config.h
  
  Compile crrcsim, it should work.
