Is there anyone in these forums who has experimented with or is using digital room correction DRC for short. I'm surprised that there seems to be little or no mention of it here.
For those of you who are wondering what I'm on about, take an amplifier that comes with built in auto-calibration and calibration mic and you have the basis for what I am referring to here. DRC takes this concept to an entirely different level. with a professional calibrated measurement mic and the right software it's possible to have a computer based profile that compensates for room time delay and phase for each speaker with crossover points and room frequency response correction. You can create a listening room calibrated to near perfection.
I'll admit that I don't have a digital room correction setup myself and at first I was somewhat sceptical of the idea but further reading indicates that anyone who aspires for perfect audio reproduction should be take DRC very seriously, even if you're someone such as myself who tries to avoid changing the natural tone of a speaker. Remember that unless your room has had extensive acoustic treatment, that that pair of speakers you have which the manufacture rates from 20hz to 20khz at +/-2db are not made to compensate for the acoustic properties of your typical listening room. In fact the average listening room has a variation of up to about 12db across the frequency range.
I highly recommend reading the following links that were posted in the jriver forums, there's a HUGE amount of detail here.

Conclusion (http://www.computeraudiophile.com/blogs/Hear-music-way-it-was-intended-be-reproduced-conclusion)
Audiolense is a software package recommended for effectiveness and ease of use, they also sell "entry level" calibrated microphones and mic pre-amps

Some packages such as ultimate equalizer which appears to be quite in depth Here (http://www.bodziosoftware.com.au/) go so far as to recommend that each point of a three way speaker for example has the crossover removed and driven by independent amplifier channels for each speaker of a home theatre system by using say a 12 channel amplifier. That way the individual crossover points for each speaker can measured and calibrated. With the use of professional multichannel sound cards you can create a calibrated computer based multichannel audio pass through for the rest of your audio system.
