Abstract
A sound receiving processing method and a sound signal processing apparatus are provided. In the method, multiple input sound signals are received through a microphone array. The input sound signals are combined into a main sound signal based on beamforming. Multiple primary extraction signals belonging to the main sound signal are respectively extracted from the input sound signals. Multiple estimated sound source signals corresponding to the sound sources are separated from the primary extraction signals through blind signal separation. Multiple re-extraction signals belonging to the estimated sound source signals are respectively extracted from the primary extraction signals. A distance of the first source relative to the microphone array is determined according to a power ratio. One of the estimated sound source signals corresponding to the first source is determined according to a distance limit. Therefore, the sound signal from the desired sound source could be obtained.
