Are there any PC sound cards I can buy which support "digital room correction", a feature found on high-end amplifiers, namely the ability to use a microphone to automatically calibrate your sound card to create "sweet spot" that has excellent frequency response?
Update
Searched for "Digital Room Correction", and found DRC: Digital Room Correction, software to help do just what I've described. The author of this program is using a TerraTec EWX 24/96 sound card. However, I'm looking for other sound cards with this ability built in as part of the sound card driver.
Update
Found DRC - Digital Room Correction - Wiki.
Update
Found AudioLense from http://www.juicehifi.com/. Plug a microphone into your sound card, and this software corrects for the acoustics of your room. Now to find some more competitors to this software, for comparison.
Update
AudioLense recommends "Professional sound cards or DACs from Lynx or RME." Its a pity these cards are the price of a Small African Nation.
