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 program 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  measurements.  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.

       refsweep:    reference channel sweep file name
       mingain:     min gain for reference channel inversion
       dlstart:     dip limiting start for reference channel inversion
