Abstract
An apparatus, system and method for a portable microphone array system comprising a computing device and a case having an array of microphones embedded or integrated into the case. A user may position the laptop and case facing the general direction of a target audio source to capture a target acoustic audio input at the microphone array. The microphone array may deliver a first stage of beamformed audio from the acoustic audio input to the computing device via a communications interface or bus. The computing device may comprise an audio processor configured to perform one or more successive audio processing steps to process the audio input and render a digital audio output. The digital audio output may be outputted from the computing device to an audio output device, such as headphones or an earpiece.
