发明名称 METHOD AND APPARATUS FOR AUDIO PATH FILTER TUNING
摘要 Methods and apparatus for tuning the audio path response of an audio device are described herein. The audio output of an audio device is captured and monitored over a predetermined frequency band. The frequency response of the captured audio output can be compared to one or more predetermined limits defining an acceptable frequency response. One or more dynamically configurable bands can be defined, and one or more parameters affecting the response within each configurable band can be adjusted. A simulated frequency response is produced and filter coefficients for a corresponding filter within the audio path are determined. The filter coefficients can be loaded to a digital filter within the audio path to modify the actual frequency response produced by the audio device.
