Abstract: The present disclosure discloses a sound signal processing method and apparatus, and a computer-readable storage medium, and belongs to the field of audio processing technologies. A device first obtains first spatial location information of sound pickup space and second spatial location information of a plurality of microphones deployed non-linearly, and then determines, based on first sound signals respectively received by the plurality of microphones and the second spatial location information, a spatial location of a first sound source that emits the first sound signals. If the first sound source is located in the sound pickup space, the device performs enhancement processing on the sound signals emitted by the first sound source. In the present disclosure, sound sources in different space are distinguished, so that only a sound signal emitted by a sound source located in the sound pickup space is enhanced.

Abstract: Embodiments of this application disclose a tracking control method. When a sound source object makes a sound, a control device determines an azimuth θ1 of the sound source object relative to a first microphone array based on detection data of the first microphone array, and determines an azimuth θ2 of the sound source object relative to a second microphone array based on detection data of the second microphone array. The control device determines a location of the sound source object based on the azimuth θ1, the azimuth θ2, a location of the first microphone array, and a location of the second microphone array. The control device controls, based on the location of the sound source object, a camera to shoot the sound source object to obtain a tracking video image. According to this application, a speaker can be accurately recognized, to improve accuracy of automatic tracking.

Abstract: A data transmission method, where a host acquires parameter information of a wireless communication channel between a wireless microphone array and the host, that is, a signal-to-noise ratio or bandwidth. The host reduces sampling frequency of the wireless microphone array or decreases a quantity of data transmission paths between the wireless microphone array and the host when the acquired parameter information satisfies a first preset condition such that bandwidth occupied when the wireless microphone array transmits data is reduced.
