Digital room correction

All music played on my system runs through a filter which corrects the overall impulse response, frequency response and phase response of my playback chain. This filter is computed with Denis Sbragion's DRC program. Its input is the recording of a sweep signal played through the system, the recording is done with a calibrated ECM8000 measurement microphone.

The effect of this filter is quite dramatic, it gets the sound "right". This is an essential part of my stereo setup.

FIR filters can be efficiently applied with Anders Torger's convolver program brutefir.
