Room Correction Digital Room Correction is using a processor to correct the interaction between the speakers and the room.
Proper DRC requires measuring the response using a calibrated microphone at the listening position. This measurement is used to generate a target curve, one that compensate for the amoralities caused by the interaction between room and speakers.
Digital Room Correction DRC is a program used to generate correction filters for acoustic compensation of HiFi and audio systems in general, including listening room compensation.
DRC 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. If you are currently using a computer to serve up your music, you may be interested in trying digital room correction.
I've been using correction for many years. I've tried a number of digital room correction software and hardware solutions, ranging in price from free to many thousands of dollars.
While I am currently using a hardware solution, a very effective solution is the free and open source DRC package. Unfortunately, DRC is quite difficult to learn to configure and use effectively. A few months ago I started spending some free time writing software to make the process of creating impulse responses and digital correction filters easier with DRC.
Basically the program is a graphical interface to the impulse recording and filter creation process. You can record impulses at different sample rates and easily create the standard filters that some with DRC, but also create filters suited to your tastes with the customized filter feature.
The program will automatically create the configuration files to load filters in convolver VST, which is also included in the release as well as DRC. The program currently only works under Microsoft Windows but I am planning on releasing a Linux version when I am happy with the Windows version.
Digital Room Correction Designer was created to ease the process of creating and loading room correction filters for use with two channel stereo systems.Product life cycle 1.
