| titleOfInvention | Method and apparatus for audio processing |
| abstract | An audio apparatus comprises a circuit (201) for applying a dynamic range adjustment processing to an input signal to generate an output signal for rendering by a loudspeaker (101). The dynamic range adjustment processing is dependent on a set of dynamic range adjustment parameters. A first linear echo-cancellation filter (203) generates a first compensated signal from the audio input signal and a first adapter (205) determines a set of filter parameters for the first linear echo-cancellation filter (203) in response to the first compensated signal and a microphone signal. An audio circuit (207, 209) generates a second compensated signal by applying the dynamic range adjustment processing and a second echo- cancellation filter (209) to the input signal where the second echo-cancellation filter (209) corresponding to the first echo-cancellation filter (203). A second adapter (211) determines the set of dynamic range adjustment parameters in response to the second compensated signal and the microphone signal. The approach can increase linearity and echo-cancellation for many systems. |
