Convolution Reverb - A computationally demanding, but very accurate method, of creating artificial reverberation derived from real acoustic spaces with all their natural complexity. In essence, a reverberant space is measured to obtain its unique impulse response. That impulse response is then convolved with a \'dry\' (reverberant-free) source signal to create an output signal which contains the original (dry) source signal with the desired room\'s reverberation char
