摘要： A microphone system for a boomless headset is disclosed, comprising a microphone array and a processing unit. The microphone array comprises Q microphones and generates Q audio signals. A first microphone and a second microphone are disposed on different earcups, and a third microphone is disposed on one of two earcups and displaced laterally and vertically from one of the first and the second microphones. The processing unit performs operations comprising: performing spatial filtering over the Q audio signals using a trained model based on an arc line with a vertical distance and a horizontal distance from a midpoint between the first and the second microphones, a time delay range for the first and the second microphones and coordinates of the Q microphones to generate a beamformed output signal originated from zero or more target sound sources inside a target beam area, where Q>=3.

摘要： The invention discloses a stereo enhancement system and a stereo enhancement method. The stereo enhancement system includes a beamforming unit and a signal processing unit. The beamforming unit is used for receiving a plurality of input sound signals and generating a plurality of beamforming sound signals corresponding to a plurality of direction intervals respectively. The signal processing unit is coupled to the beamforming unit and used for receiving the plurality of beamforming sound signals corresponding to the plurality of direction intervals respectively and generating a first synthesized output sound signal and a second synthesized sound signal accordingly.
