Abstract (en)
The present invention relates to an electronic device (10) for receiving and transmitting audio signals. In order to provide an electronic device which sufficiently allows filtering out background noise from audio signals and which further allows creating and/or using context information with regard to such background noise, said electronic device (10) comprises a first microphone (11) for detecting audio signals, at least one second microphone (12) for detecting audio signals, a processing unit (13) for receiving said audio signals from the at least two microphones (11, 12), for processing said audio signals and for filtering out background noise from said audio signals and a communication processing unit (14) for transmitting (15) the remaining audio signals to an electronic receiver device (16). Advantageously, said electronic device (10) further comprises an application interface (21) to an application processing unit (20), upon which specific inquiries to the processing unit (13) can be generated.
