1. Any one is having an software to simulate
Loudspeaker-enclousure-microphone(LEM) or room accoustic ?
2. what are the algorithms we use to simulate LEM?
3. anyone is having matalb/SCILAB code to simulate LEM ?
LEM simulation

Hi Jedi,
thanks for reply,
do u have sample of code(mat/scilab or c code) to
implement fir filter?
I want to know which fir filters are optimum to
implemet this room accoustic?
in case of long impulse response With a modest
sampling rate of 8kHz, a FIR filter of order 32,000
will be required. This is quite unpractical with fir
filter
Then IIR filter would be better one which would be
implemneted with comb and all pass filters.
what is ur opinion with this ? --- Li Maoquan <LiMaoquan2000@LiMa...> wrote:
