       brp-pacu - dual fft live audio analysis program




       This  manual  page documents briefly the brp-pacu program.  This manual
       page was written for  the  Debian  distribution  because  the  original
       program does not have a manual page.

       brp-pacu  is  an audio analysis tool to configure any sound system with
       an equalizer.  It compares the output of the system to the input of the
       system and allows you to use this data to perform final equalization by
       matching the results with actual DSP/EQ.

       Channel 1 is the output of the  system  we  are  observing  (measured),
       channel  2 is the input (reference).  You also need a decent calibrated
       omnidrectional microphone (reasonably flat  20Hz-20kHz)  and  either  a
       USB-Preamp like the 2-channel M-Audio, or a mixer with a 30dB pad or so
       going into the laptop mic input.  No Pad is necessary if you are  lucky
       enough  to  have  a  laptop or PC with a line input.  The headphone out
       will have the pink noise.

       brp-pacu works through Jack Audio Connection Kit.


       This program takes no arguments
