There are two camps with regards to audio quality:
A) The original is perfect, and all processing is bad processing
B) Good sound is the goal, and sometimes processing can help
[edit -- after thinking more, there's also a C) Processing can be good, but I want to do it in my external hardware because, well, it was expensive]
Great audio discussion threads today, very interesting reading with tons of new information.
In regards to the audio quality camps, I think a lot of people start "Camp A" and move to "Camp B" (spending a lot of money in Camp C in the process.
I'd love to use the current feature set of Media Center to reach a "better campsite" for Camp B. If there was a way to use active software room correction with the parametric EQ, I think a lot more audiophiles and audio nuts would use the DSP features of MC. I'm a two channel user, so I don't have Audessy Room Correction or other hardware equalizers in my integrated amp. But still, there is a lot of room for improvement in getting flat response out of my speakers.
Jmone wrote about his big subwoofer blowout competition that utilized a third-party microphone software that could measure room response with an SPL meter. Could this work for 2-channel as well?
In any case, I'd love to learn how to use the parametric EQ better and what has worked for others in terms of room acoustic correction. Right now I just stab in the dark, running from couch to MC and back playing with settings!
