I'm not sure whether REQW has a feature to display phase response. Some other packages do (e.g. Acourate, which will also chart group-delay).
The graphs you posted were created with the Octave scripts which ship with DRC. These scripts make a series of reallyinteresting charts. But right now, charting the impulse response from ImpulsePrep with these tools is pretty difficult; you need to export the original and test-convolution impulse responses in 32f raw format and pad it with silence at the start (and then get to grips with Octave, and TeX/hevea to produce HTML). In the next version of ImpulsePrep there will be a commandline flag to export the measurements in the right format for these Octave scripts, which will make the process a bit easier. -- 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
