[QUOTE="Mark DeArman, post: 57227, member: 950"] Re: How to build a flat-phase DSP preset? I would just set the delay appropriate for the temperature and start creating filters from that point. If your DSP changes the overall delay based on the the number of EQ positions "ON", then I would just turn on all the ones you think you need, set the delay, then start modifying them. Unwrapping the phase curve or viewing on a non log scale might help with visualization. Also the group delay, (negative derivative of phase curve) might help make viewing easier. It seems to me that visualization and systematic application of method is the major stumbling block for phase equalization for many people. I'm sure Mr. Beckman has a lot more to say on the method aspect of things. [/QUOTE]
