The file in question is the _target_ curve, which could be flat, or one of the others (the one I use gradually rolls off in the treble-- if you open up one of the files, you'll see frequencies, followed by tab characters, then by numbers representing how far up or down you want the target to be). The "flatness" control in the inguz plugin will make the curve closer to the original response or the target, depending on how you set it. If you choose the flat target, it will indeed make it closer to flat. I haven't created new filters in a long time, so I don't know if there are new problems, but I never saw error messages like the ones you had. Could you tell us what the exact command line you typed was? It could be something as simple as not having gotten the command line right. -- totoro squeezebox 3 -> mccormack dna .5 -> audio physic tempo 4 ------------------------------------------------------------------------ totoro's Profile: http://forums.slimdevices.com/member.php?userid=5935 View this thread: http://forums.slimdevices.com/showthread.php?t=29489 _______________________________________________ audiophiles mailing list audiophiles@lists.slimdevices.com http://lists.slimdevices.com/lists/listinfo/audiophiles
