Abstract:
1. An apparatus for emulation of electronic non-linear audio equipment, the apparatus configured to modify a received input audio signal into an output audio signal, comprising: an input interface for receiving an input audio signal and producing a first signal; a dynamic non-linearity (DNL) including at least three static non-linear (SNL) functions, said DNL being arranged such that a mode parameter decides which one of the at least three static non-linear (SNL) functions will be active, said DNL being further arranged to operate on said first signal and produce a second signal; a mode estimator configured to receive said first signal as an input, said mode estimator being further configured to determine a mode as a function of at least one previous value of the first signal, and configured to transmit the determined mode to the emulator, an interface for outputting said second signal as an output audio signal.
