I'm about to embark on a project to capture impulses of the many guitar cabs I seem to have accumulated over time and at this point just looking at the cabs rather than the amps (i.e. not looking at anything groovy like dynamic convolution for capturing tube amp characteristics) - My ultimate goal here is to have captured sufficiently the cabs I use most infrequently to free up house space, so I'm planning on only doing this once as they'll no longer be around.
Question for those who have done speaker cab impulses: What length sweep did you use? I'm presuming a sweep is better than a click to allow for the physical response of the speaker, and was thinking of using something like a 0.5 sec sweep to keep convolution processing effort low...
Any thoughts or tales of experience from those who have already tried...?
