摘要：In a method and system for frequency compensation in an audio CODEC, a filterin a hardware audio CODEC may be configured based on power consumption and basedon a frequency response of an active output device to which the filter is communicativelycoupled. The filter may comprise a plurality of filter stages, which may be, for example,biquads, and the filter may be configured by enabling or disabling one or more of thestages. In this manner, power consumption of the filter may be managed by enablingand/or disabling one or more stages. Configuration of the filter may be performeddynamically depending on whether one or more audio output devices may be active. Inthis regard, which output device is active and its frequency response may be determinedand filter coefficients may be reconfigured upon a change in which output device may beactive.
