ANTI-FEEDBACK DEVICE

摘要

A feedback-prevention method for a system with a signal processor comprising the steps of inputting at least one reference signal (9); calculating a spectral model (11) of the system according to the or each reference signal; generating a preventative gain compensation factor (12) according to the spectral model of the system; applying the preventative gain compensation factor (16) to the input or output of the signal processor (2); and outputting a gain-compensated audio output (3).
