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.
