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
