Abstract

A system for detecting, classifying and tracking unmanned aerial vehicles (UAVs) comprising: at least one microphone array arranged to provide audio data; at least one camera arranged to provide video data; and at least one processor arranged to generate a spatial detection probability map comprising a set of spatial cells. The processor assigns a probability score to each cell as a function of: an audio analysis score generated by comparing audio data to a library of audio signatures; an audio intensity score generated by evaluating a power of at least a portion of a spectrum of the audio data; and a video analysis score generated by using an image processing algorithm to analyse the video data. The system is arranged to indicate that a UAV has been detected in one or more spatial cells if the associated probability score exceeds a predetermined detection threshold.

Abstract

A method for enhancing audio performance of sound recorded at different positions in a room 100 or area. Audio enhancement algorithms are applied to recorded sound based on analysis of recorded sound from several microphones 110 in the room 100 or area, together with position information of each microphone 110.

Abstract

Method and system for performing position dependent feedback cancellation, when capturing sound in a restricted area. The area is scanned by capturing sound emitted from loudspeakers, and where this is done at different positions. The captured sound is assessed with regards to feedback problems at the different positions, and this feedback information is stored in a memory. Feedback audio effect measures are the applied on captured sound from specific input positions, and where this is done by looking up in said memory relevant feedback information corresponding to said input positions.
