This is neat! Matt here down in little old NZ.

Got it. Surprisingly the LFE and sub from L are identical (almost) in timing today.

I can't even replicate your curves....

Have you used the results from today (post 7 and not post 1) as the timing between each day seems to be changing!

Well this is weird. Today everything seems to be well lined up to each other (using the original audysee sub distance). The alignment tool is almost identical to the real scenario.

Also why is the sweep length frequency completely altering the LFE response impulse calculation? (from about .6m to 0.38m)

THanks I will do this today. Yes the L R are always set to Large, as they are 804 D3's and have a sizeable power amp attached. (plus they are usually hi level to the REL but for the purposes of this excercise I have left that unconnected for now). Any thoughts on why most of the channels apart...

yes, so adding a little bit of distance would seem to be correct? (delaying all other channels)

Hi All. I'm checking the after-cal distances with REW and find that most channels, except the surround rear L and R and the surround L, are off with the impulse response. The SUB is well off when checked with REW. Denon Avr 4520 with audysee XT32 1) asio output 7.1 hdmi with surround Back...

THis needs to be re linked - the new version is at least 5.50. This link/download is 5.43

great John - dB problem is resolved with beta 18.

Hi JOhn - yes it's one of the newer 18 gain ones and using the 90 deg cal - nothing has changed with how I'm using it between beta 15 and 16/17. All the input and ASIO settings as as usual. The cal file is input in the new fashion in 16/17 in the new cal tab. Sens Factor =-0.010989dB, SERNO...

sweep volume levels are still audibly equivalent and still at -12dBFS. Umik-1 90deg cal used as usual and checked that mic input on the computer still at 81. HDMI output still at 100. win 10 64 bit

Using Beta 17 - my DBa values all seem to be half the amplitude after going from beta 15 --> 16 (and 17). Some changed parameter? sweep values are now in the 30 ish db range and background about 26Db!!! real quiet.... not!!!
