FYI, have any of you ever used the "Taper" function?
Lorr mentioned the Taper function and the reverb/window function too, but I never really played with it much.
Anyway, you can check page 89 of the manual.
Lorr had also mentioned that my own speaker system, the Cello system, in my super bright room was a perfect candidate for playing with the Taper function.
Basically you can "taper" the impulse responses in the PRIR which effectively "tapers" the room reverberations. The net result is that the "brightness" of my room can be reduced significantly making the Realiser output sound better than my actual room! By tapering the impulse response, the timbre and localization of the speakers is unaffected.
I have to say, it's not perfect, but it is interesting to take my really bright room and taper it all the way down from slightly reduced to virtually anechoic. (When tapering down, I still think there are some artifacts since the original PRIR has a lot of reverb and simply cutting or tapering off that info doesn't make it exactly the same as if I had the speakers in a much more damped room.)
Previously, my Cello PRIR was of limited use. It worked well on music, but was way to reverberant to work well with movies or any surround sources. Now with it tapered, it sounds really good. I love the way the speakers sound, it was just the room that was causing problems.
Anyway, if you are interested, download/load my Cello PRIR, and you the Taper function when loading the PRIR. I tried the following values: "S:100ms E:150ms" with pretty good results.
Here's the excerpt from the manual:
For PRIRs made in reverberant rooms, the user may wish to alter the reverberation decay. Upon
loading a PRIR into a preset, the Realiser allows the user to set the start and end points of a taper for
When a PRIR is to be loaded into a preset, the user presses MENU and then the target preset key. As
an example, for preset 2 the user would press MENU-P2, and then choose PRIR PRESET 2. The
screen will say:
Move the cursor to the second line. The < key will increment the start point of the taper by 50 ms, and
the > key will increment the end point by 50 ms. The default of 800 and 850 represents a 50 ms taper
on the full 850 ms capacity of the Realiser. The start and end points can be adjusted separately to
create tapers longer than 50 ms; the minimum taper is 50 ms. The controls are independent except that
the 50 ms minimum may cause the two values to move together, and the start point limits the end point
When a taper has been set, the preset window will show an indication as follows.

The taper control is somewhat similar to the REVERB control on the MENU-ALL screen and the
WINDOW control in the virtual speaker setup menu 2. The differences are: (1) the taper is just that, a
linear taper providing a fade to zero, whereas the REVERB/WINDOW control truncates the reverberation
tail; and (2) the taper must be set upon loading the PRIR into the preset, whereas the
REVERB/WINDOW control can be varied while listening to a preset. One can initially adjust
REVERB/WINDOW to see if reverb reduction is desired; then use either control for the desired result.
Let me know what you think.
(BTW, Kiritz, you might find this especially useful since you have your PRIR done at my house.)
