Impulse response table for FFT?

Hi:

Playing with FFT--IFFT here...

I want to multiply an impulse response with a music signal.

The challenge is- there seems to be no way to 'load' an impulse response file into an FFT?

In other words, much like creating an FIR: need a way to load the coefficients and perform an FFT...

Also- anyway to use external memory with the block processing?

Using the 1466 chip ( great part, BTW).

Help...

Thanks,

Gary
