Abstract
Embodiments of the present disclosure provide systems and methods for source localization using a microphone array. Such an embodiment, among others, utilizes circuitry to process audio signals and microphone signals to remove an echo (produced by a nearby loudspeaker) from the microphone signals using a plurality of adaptive echo cancellation filters. Location information is then determined for the loudspeaker based on the plurality of adaptive echo cancellation filters used to remove the echo.
