Abstract

An audio signal processing apparatus comprises at least one controllable element 90, 91, 92 for performing an analogue audio processing function. The controllable element is operable with a digital controller 58 that controls the analogue audio processing function performed by the controllable element 90, 91, 92. At least one audio processing module 52, 54 comprises a partial audio processing circuit for an audio processing operation. The module 52, 54 is operable with the controllable element 90, 91, 92 to complete the audio processing circuit and thus to enable the audio processing operation. In this way the audio processing operation is controllable by the digital controller. A switching array 96 selectively couples audio processing modules 52, 54 and the controllable elements 90, 91, 92. A power supply 66 is operable to supply power selectively for audio processing circuit of the or each module 52, 54.
