Portable microphone array apparatus and system and processing method

A portable microphone array system comprising:

• a portable housing comprising a plurality of transducers coupled to a surface of the portable housing, the plurality of transducers comprising an array being configured to receive an arriving audio signal;
• and
• a computing device selectively coupled to a surface of the portable housing, the computing device comprising an audio processing module communicably engaged with the microphone array via at least one data transfer interface to receive the arriving audio signal,
• wherein the audio processing module is configured to process the arriving audio signal according to one or more audio processing steps to spatially filter at least one target audio signal from one or more non-target audio signals present within the arriving audio signal to generate a processed audio output.

A portable microphone array system comprising:

• a portable housing comprising a plurality of acoustic sensors comprising a microphone array configured to receive an audio input;
• and
• a computing device selectively coupled to at least one surface of the portable housing, the computing device comprising an audio processing module communicably engaged with the microphone array via at least one data transfer interface to receive the audio input, the audio processing module comprising at least one processor and a non-transitory computer readable medium having instructions stored thereon that, when executed, cause the processor to perform one or more audio processing operations, comprising:
• processing the audio input to determine at least one acoustic propagation model for at least one source location within an acoustic environment;
• and
• processing the audio input according to the at least one acoustic propagation model to spatially filter at least one target audio signal from one or more non-target audio signals within the audio input to derive a processed audio output, wherein the at least one target audio signal corresponds to the at least one source location;
• and
• rendering a processed audio output comprising the at least one target audio signal.
