LSCONV(1) General Commands Manual LSCONV(1)NAMElsconv - a program does Log Sweep convolution.SYNOPSISlsconv [parameters] sweepfile inversefile Usage: lsconv sweepfile inversefile outfile [refsweep mingain [dlstart]] Example: lsconv sweep.pcm inverse.pcm impulse.pcm refchannel.pcm 0.1 0.8DESCRIPTIONThis 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.PARAMETERSsweepfile: 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 Refer to html documentation for more details.SEE ALSOsox(1).AUTHORThis manual page was written by Jaromir Mike <mira.mikes@seznam.cz>, for the Debian project (but may be used by others).
