We have those in BaltimoreRadio controlled blimp with a downward facing microphone attached and small recorder? Point the cab directly up?

High Cut and Low Cut.Is there a way to cut a set width slice (kinda a Q control) out of an ir? Maybe even a slider to choose the start and end point of the range? And hopefully monitor the results in real time?

High Cut and Low Cut.
Heh. I read “kinda a Q control,” and figured he wanted to pare away frequencies.Time domain.
Frequency domain.
The best way to proceed is to begin with the best possible data.
If you know that an IR of a speaker you've swept has reflections affecting its frequency response, take the steps acoustically necessary to insure that there are no reflections or diffractions within the measurement window.
Time domain.
the IR alignment knob used to do that back in january, FW 2.05, it would slide the IR inside the fixed window, you could hear it move even with just 1 IR active, you could slide it over until you could hear it line up, with most of the OH non MPT ones I was using the voodoo was putting the main bump on about 1ms, it lined up in phase and came into automatic focus like you would n o t b e l e i v e. Alignment knob doesn't do anything any more if you're only got one IR active. You can trim the length with the length preset selection but it's fixed to 256/512/1024/max...no front/back length trim knobs yet...front/back trim knobs would be super powerful, you could tune any IR to respond just the way you like...high/low cut knobs work great but the IR window changing the time domain is so much better way to EQ everything, when you get it lined up right, getting stuff in phase is like getting the mic in the right spot, everything balances out to where you've got all the lows, all the highs, low-mids are scooped in the right spot, clear as a bell and strong at the same time...no EQ necessary

If only one IR is active all the alignment was doing was adding delay. It didn't change the trim point, that moved in the same direction. As all it was doing was adding unnecessary latency so the "feature" was removed.the IR alignment knob used to do that back in january, FW 2.05, it would slide the IR inside the fixed window, you could hear it move even with just 1 IR active, you could slide it over until you could hear it line up, with most of the OH non MPT ones I was using the voodoo was putting the main bump on about 1ms, it lined up in phase and came into automatic focus like you would n o t b e l e i v e.

It didn't do anything but add latency. There is no such thing as "time space". You can achieve the same effect by moving further away from your monitors. Read what I wrote again, several times if necessary.that feature was magic! it worked so well to compensate for different IR lead times when you aren't using MPT, get the impulse to sit right where it should be in time space, while keeping all the clarity of non-MPT IRs...
To be sure it really makes a difference record a sample with each one of those settings and listen back.Well that was just phase shift effects against what amounts to the same thing as cab 'air', that doesn't count...
But how bout this...
Cab block channel A:
IR 1, Factory 2 800, pan center, 0.00 dB
IR 2, Factory 2 800, pan center, 0.00 dB
both mic distance 0.00 mm
Cab block channel B:
IR 1, Factory 2 800, pan center, 0.00 dB
IR 2, Factory 2 800, pan center, 0.00 dB
both mic distance 212.2 mm
Cab block channel C:
IR 1, Factory 2 800, pan center, 0.00 dB
IR 2, Factory 2 800, pan center, 0.00 dB
both mic distance 264.2 mm
That's two of the same IR lined up exactly, should be identical L/R...makes a huge difference in tonality depending on where you drop the start point...
To really hear the difference turn up super loud and palm mute chug switching from channel A to channel C...
My guess is that you are just "feeling" the tone
How did you get on with this Cliff?I'm going to work on an auto-correlation display over the coming days and see if that can help in identifying early reflections.

Why don't IR producers hire out a large enough hall (or aeroplane hangar...) to capture a long sample free of reflections or impurities?
I understand the cost involved is probably prohibitive, but surely you could even just do it on an oval or something. pointed towards the sky?
