Maybe I should start a separate thread for this question but I'll try it here in regard to adjusting the EQ. Now that I have the experimental equalizer in place I've been attempting to achieve the R/L balance not just for volume balance but for frequency balance as well. This activity is not as straightforward as I, without much thought, anticipated because changes especially in the mid to upper frequencies affect the directionality and, therefore, perception of where the sound source is strongest.
So, this is the approach I've been trying. Starting with right and left channels set at neutral volume and flat frequency settings I used an audio test CD and stepped through frequencies listening to how closely centered the signal seems. As I come to a frequency that appears weighted to the right side I adjust the dB on the left side of that approximate frequency upward until the tone centers. I do this through to 8 KHz where my ability to hear pretty much ends.
Here's where it stops being simple. It seems that increasing the dB of those frequencies resulted in my overall perception of balance change when listening to music, migrating now to the left side. Using music to adjust balance, though, has other issues, mostly I think, based on how the music was recorded in the first place. For example, I listen to some small jazz groups which seem to record in a way that represents poisoning of various instruments accentuating, for example, that drums are located at stage right. This seems especially to be the case with the older recordings when there seems to have been more effort given to demonstrating stereo effect.
I don't claim to know what I'm doing here but, regardless of that, I'm very much satisfied, so far, with the listening improvement resulting from the addition of this equalizer.
