Abstract (en)
A method for sound source separation using a linear microphone array, the method comprising the steps of: calculating distance of each microphone of the microphone array to a known location of a target that is to be sampled; for each microphone calculating a delay with which sound reaches the given microphone from a given location in space; identifying a microphone having the lowest value of the delay and subtracting this value from values of delays of all other microphones; calculating a sound sample for a given location in space by adding sound samples from all microphones while taking into account the respective delays.
