[QUOTE="Mark Wilkinson, post: 202179, member: 8989"] Most Excellent Michael, The "Design + File" in the Target tab makes putting shelving filters that span multiple band-passes very easy..THX ! The addition of IIR filters, that are not part of the FIR generation, is really going to help with not having to use some additional processing for sub and mid high-pass filters, when either taps aren't available, or if they are, using them takes latency too high. I mentioned in email, that I found out the increased transient definition I was hearing FIRd vs rePhase, ended up being (embarrassingly) nothing more than level differences between the MF section, and the HF/VHF drivers. Could you quickly explain how the Normalize buttons work in the Import and Target tabs? I'm pretty sure my inconsistency in their use across driver sections caused the level differences..... And of course i have another humble request..... sorry :) After generating a FIR file and then measuring the speaker's response with Smaart, I try to clean up any measured deviations. So it means I need to either use another source of IIR eq that introduces phase shift, or to put that same eq that cleans response up, into the FIR generation stream. What might be a neat way of doing this, could be the ability to overlay filter adjustments post measurement, like in Direct Design, that become part of Target curve. This would then include the adjustments in the FIR generation. I know I can start the whole process over by beginning with a target curve generation that includes needed adjustments, but that's a pretty lengthy process......when all I really want to do is add a few band-pass eqs inside the FIR...then regenerate, and go quickly measure again... Hope I made sense here... As always, many thanks ! [/QUOTE]
