Sorry for the delay. I got REQW and converted the one file using Goldwave as suggested. I would love to post the files to get some input, but still have no clue how to get from the .wav impulses to a viewable image as all of you have done. I'm sure I could figure it out with some time playing around with REQW, but it looks as if there is lot to learn. Is there a quick procedure that will allow a novice like me to get my impulses into a postable visual format? I really don't want anyone to waste their time tutoring me on the ins and outs of REQW, but at the same time I'm curious to get some feedback from you all. If the only practical way for me to post is just buckle down and learn REQW myself say so, and I'll try to find some time. -- esbrewer ------------------------------------------------------------------------ esbrewer's Profile: http://forums.slimdevices.com/member.php?userid=12409 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
