Graphs for low frequency response depend very heavily on the length of the impulse response measurement, or the length of the FFT window used to analyze it. The difference in your red and green chart lines is probably just that REQW used a shorter measurement window.
I charted your impulse response with RMAA and a 32k FFT window gives this: RMAA unfortunately doesn't have a "third-octave smoothing" option, so the higher freqs look very noisy on the chart. But it does clearly show the 300-400Hz peak and the lift above 4k. +-------------------------------------------------------------------+ |Filename: Spectrum_rmaa_32k.png | |Download: http://forums.slimdevices.com/attachment.php?attachmentid=2877| +-------------------------------------------------------------------+ -- inguz ------------------------------------------------------------------------ inguz's Profile: http://forums.slimdevices.com/member.php?userid=1139 View this thread: http://forums.slimdevices.com/showthread.php?t=35615 _______________________________________________ audiophiles mailing list audiophiles@lists.slimdevices.com http://lists.slimdevices.com/lists/listinfo/audiophiles
