NAME

       brp-pacu - dual fft live audio analysis program

SYNOPSIS

       brp-pacu

DESCRIPTION

       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.

NAME

       lsconv - a program does Log Sweep convolution.

SYNOPSIS

       lsconv [parameters] sweepfile inversefile

       Usage: lsconv sweepfile inversefile outfile [refsweep mingain [dlstart]]

       Example: lsconv sweep.pcm inverse.pcm impulse.pcm refchannel.pcm 0.1 0.8

DESCRIPTION

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

       lsconv is program to perform accurate time aligned impulse response measurements.

       lsconv is based on the log sweep method for impulse response measurement, which is one of the most accurate, especially for  acoustic  mea-
       surements. This method is based on a special signal, which is a logarithmic sinusoidal sweep, that need to be reproduced through the system
       under test, and an inverse filter, which, when convolved with the measured log sweep, gives back the impulse response of the system.

       Files used by lsconv must be in the raw 32 bit floating point format. Use for e.g. sox program for converting if needed.

PARAMETERS

       sweepfile:   sweep file name
       inversefile: inverse sweep file name
       outfile:     output impulse response file
       refsweep:    reference channel sweep file name
       mingain:     min gain for reference channel inversion
       dlstart:     dip limiting start for reference channel inversion
