I'm experimenting with equalizing my full-range speakers using the Inguz plugin for Slimserver (my source is a squeezebox 3). I'd been using the program drc to generate the correction filters, but I'm finding that the filters I make with REW give results that are at least as good, and it's much easier to adjust and check results with it.

Without knowing very well what I was doing I seem to have fallen into the good practices described in the thread linked to above - that is, I'm using pretty broad filters at high frequencies, since I quickly discovered the futility of trying to get rid of every peak. The improvement is greatest in the bass, but I've found the mid and treble are improved too (which I think is more a question of achieving the balance I like best than of equalizing to a flat response).

I'm curious to learn more about the differences between drc and REW. The algorithm drc uses to generate correction filters is much more complex than just adding some peak filters - it does fancy things with phase, for example. But in the end the results don't seem to be audibly better. Still, I wonder what a program combining the ease of use of REW and the horsepower of drc might be able to do.

At the moment things are stalled while I wait for a longer mic cable to arrive (as things are now the measurement process is a real pain, and the cable will make it much easier). I'll report back when I've made some more progress.
