Digital audio signal processors

摘要

A digital audio signal processor processes digital audio signals having a first sampling rate S1. The processor has a multiplicity of manually adjustable controls (403) for setting desired parameters of signals to be processed. Sampling means (404) sample each control (403) setting at a second sampling rate S2 less than the first rate S1 to determine the settings thereof. Applying means (401) responsive to the sampling means apply the sampled settings to the signals. For each control the applying means determines the difference of successive samples of setting and applies to the signal, subject to control by that control, increments of setting each increment being a predetermined fraction 1/n of the said difference at a rate nS2 which is n times the said second sampling rate S2.
