DSP Devices for Room/Speaker Correction

PS: Can you imagine listening to your "speakers" on a quality set of headphones?

Most DSP based room acoustic correction equipment assumed the listener sit at a fix location and throught a closed loop monitor and apply compensation techniques (microphone to digitizer to DSP to amplifier to speaker) nulling out the anomaly cause by interaction between the speakers and the room. The problem arise when the listening position is changing (listener move about in the room) then the system must be retrained to compensate for a new listening location. Currently there is not existed a powerful DSP device that is capable of doing that kind of realtime correction so there are still room for improvement. Cheers,

Well, Dekay, if what you say is true, a real audiophile would just absent himself from the room, if not the house altogether, and be satisfied that by doing so that he had enabled his system to play at its best. Not being able to hear his system would be just another sacrifice a real audiophile would be willing to make. Wouldn't you agree, or does this belong on another thread...

Jayboard: It was just one of those thoughts not unlike the ones that we all have when we are about to fall asleep, which is when it came to me. We probably don't need to carry it any further. The DSC devices do sound very interesting if they are an improvement on and easier to use than the old "slide" equalizers. I have set up a few systems using these and always felt that they had mixed results. They seemed to work better on large multiple driver speakers in larger rooms. There tendancy to add distortion and compress sound was more noticable on smaller systems in smaller rooms, this is just my experience. The setup task was also very demanding in that just achieveing the the first step of a flat response with test signals could take many many hours. I did enjoy the second phase of adjusting by ear, especially if the system owners were involved in process. The longest I ever spent at one system was 14 hours straight, it ended up turning into a party.

Dekay: you crack me up. Heisenberg's uncertainty principle, as applied to audiophilia.
