A method of analysing non-linear audio effects is described in which a sequence of differing level impulses is fed to a device under test. The resulting impulse responses are recorded and applied by modified convolution to input signals to simulate the sampled effect. In this way effective simulation of effects such as valve amplification and analogue recording may be achieved.
