3d sound analysis system

A sound analysis system comprising:

• a cluster of microphone modules configured in a 3D arrangement, wherein each microphone module is configured to obtain a set of bidirectional information;
• and a signal processor:
• wherein the signal processor is programmed to retrieve, from each of the microphone modules, their 3D bidirectional vector information sets;
• convert the 3D vector information sets into digital information sets;
• calculate from the digital information sets, all of the 3D bidirectional vectors for every microphone module;
• calculate the 3D intersection points of the bidirectional vectors that are common to all microphone modules, noting that only such common intersection points represent the true 3D positions of the sound sources;
• calculate the different distances from each microphone module to each sound source to thereby further calculate the arrival time difference to each microphone module from each sound source, to thereby further calculate time arrival synchronisation of the collective received signals from each sound source, to thereby via such signal correlation maximise the signal to noise ratio of received sounds;
• calculate and correct for high frequency sound roll off from each sound source;
• and
• provide as output the digital representation of the sound waves emanating in the direction of the microphone cluster from each sound source.
