@PENG, I can retake measurements with Audyssey and not use the app if that's better. I assumed I would get the same results either way. Like I said, I didn't do a bunch of tweaking or anything. I just turned off midrange compensation and uploaded the otherwise virgin file.\n\nI know enough now to take repeated measurements in both stereo and 5.1. I know how to do a full range sweep and how to isolate frequencies for smaller sweeps.\n\nI don't have the app and my AV8801 is not compatible with the app so I have to rely on users like you to tell me how it well it works. So I guess you connect the Audyssey mic to the phone right?\n\nIt would be great if you can do a comparison of using the AVR to run Audyssey vs using the phone\/tablet. I suppose you will then need to run Audyssey without using the app, then use the Umik-1 and REW to do a couple of sweeps. Then run Audyssey again using the app this time and plot the same REW graphs again after, obviously in both cases put the Audyssey mic in the same location.\n\nI know this will take a lot of your time but doing for your main listening position will be sufficient. If you don't want to be bothered, I understand. You have done a lot already.\n\nBy the way, those REW graphs show Audyssey did do a pretty good job for you. If you want it to look as good as those published on AV magazines, try using 1\/12 smoothing. I think 1\/24 smoothing is reasonable enough.
