Default Speaker Design Software

Okay I know this question gets asked a lot but I'm looking for one with a specific feature:

I'm looking for one that will let you give an input to (say, a square wave) to a virtual speaker and then give you an estimate of what a microphone outside the speaker would measure.

Are there any that can do this?

Sounds like a SPICE model to me.

Go on?

I've used PSPICE but I thought that was just for electronics?

Come to think of it MATLAB would likely be even better - if you are up to it. My brain aches at the inital thought though

I guess there's nothing that does anything like this?

OP wants to simulate time response, not measure... "virtual"

Any simulation program that will give you an impulse response would work. Then convolve the impulse response with your desired waveform. Or you could take a simulated frequency response and do an inverse FFT to get the impulse response, then convolve it. I'd use Matlab to do that processing, but you could do it in Excel if you really wanted to.
