# drc(1)

a program for acoustic compensation of audio systems

## NAME

**drc** - a program for acoustic compensation of audio systems

## SYNOPSIS

**drc** \[*options*\] DRCFile\
 **DRCFile** is name of DRC configuration file\

## DESCRIPTION

This manual page documents briefly the **drc** program. This manual page was written for the Debian distribution because the original program does not have a manual page.

**drc** is program used to generate correction filters for acoustic compensation of HiFi and audio systems in general, including listening room compensation.\
  Program generates just the FIR correction filters, which can be used with a real time or offline convolver to provide real time or offline correction.

**drc** doesn't provide convolution features, and provides only some simplified, although really accurate, measuring tools.
