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 characteristics imposed upon it. The convolution process is performed in the digital domain and involves multiplying each individual sample of the source signal with the impulse response of the convolving signal. The same technique can be employed to impose the characteristics of any other audio signal processing or signal-shaping device onto a source signal, such as the characteristics of legacy equalisers, compressors, tape recorders and so forth.
