more room impulse responses

Now I have popped a couple of balloons.  And I also recorded the millenium
fireworks.  Should give good samples for convolution.

Some of these rooms were empty, lots of resonances.
If you would hear this in a digital reverb unit, you would call
this effect "not realistic". Sometimes reality is more real
then we think it is.


Unfortunately I was not able to record the big room I was after,
20x20x20 m. First I had a real bad flu, then the draggon was always
in the office (church secretary), so I could not enter to make
a big noise. Anyway, I need to experiment with the responses I have,
in order to improve further recording.


I also tryed a free air balloon pop, I thought it would be the best to
pop it as close to ground as possible, and the mics also close to ground,
5 m away, in order to avoid ground reflection runtime delays.

What do the gurus say to this approach?

Later more.

Did you notice the new Sony effects processor for 6000 EURO?  It's a
real time convolver! You get CDs with impulse responses recorded by Sony.

There are only a few parameters to adjust, predelay and such.  It all
depends on the chosen CD file.

AFAIK this is the first real time machine.

And: Quantech is back! They made a new reverb machine.
