That's why I wrote Aliki ! It uses logarithmic sweeps - the method
pioneerd by Farina. See my LAC2006 paper for the background.

If youd don't need a 'real' room for a reverb but just some nice
effect, then any decaying burst of noise will work. Generate it
using your favourite softsynth. This way you can also make 'gated'
or 'reverse' reverb etc.
