Doesn't the 'direct' filter also use the 'flat' target, rather than say bk3 - that would account for the 20db drop off at higher frequencies. ImpulsePrep seems to be over-riding what is in the DRC config file. How can we generate a 'direct' filter using a non flat target?
Does DRC definitely apply 're-echos' to cancel reflections? I don't see any reference to that in the DRC documentation, and looking at the waterfall plots in REW I don't see any reduction apart from that due to the lower peaks. I think there is enough of a concensus that however good the DRC filters may sound, it would be worth comparing to a sub 200Hz only filter, and a notch only type filter. The question remains - how does one do that? Looking at the DRC config, there are are host of variables, one of which 'PLMaxGain = 0.0 # 6.02 dB Max' would suggest that setting it to zero would enforce a zero gain filter. I tried it, but it doesn't have the desired effect. Plus, why if the max gain is 6db do we have to use a -18db setting to avoid clipping. Also, Inguz seems to tbe suggesting that the gentle filters already hace a reduced impact at higher frequencies - how do you tune those filters further to completely elliminate any correction above, say, 200Hz. Is another alternative to use another product (perhaps REW itself) to generate a filter to import back into Inguz? -- mortod ------------------------------------------------------------------------ mortod's Profile: http://forums.slimdevices.com/member.php?userid=4651 View this thread: http://forums.slimdevices.com/showthread.php?t=35615 _______________________________________________ audiophiles mailing list [email protected] http://lists.slimdevices.com/lists/listinfo/audiophiles
