The test signals (unless they say "with EQ") bypass EQ processing and impulse filters (room correction, invert, etc) altogether. So when playing a test signal it makes no difference which filter you've selected.
I figured out why the level is different for "Invert Polarity". It's a kinda-by-design bug. For any filter impulse, the DSP adjusts the overall level to correspond with a loudness calculation -- i.e. based on the "loudness" (perceptual weighting) of the filter, the overall level is adjusted. This means you don't need to normalize filters when creating them with different packages; switch from one filter to another and the volume level will remain roughly the same. This loudness calculation was meant to be normalized but I miscalculated a bit, so when you process using the "invert polarity" filter, the overall gain moves slightly from "no correction". -- inguz ------------------------------------------------------------------------ inguz's Profile: http://forums.slimdevices.com/member.php?userid=1139 View this thread: http://forums.slimdevices.com/showthread.php?t=35884 _______________________________________________ audiophiles mailing list [email protected] http://lists.slimdevices.com/lists/listinfo/audiophiles
