Abstract
Various embodiments provide a multi-audio input, stereo audio output, push-to-talk (PTT) switch device. The device may include an audio processing unit configured to perform spatial separation/positioning for one or a plurality of audio sources. The audio processing unit of the device may apply unique head-related transfer functions (HRTFs) to produce left and right audio outputs that correspond to predetermined or dynamically positioned spatial locations for each of the incoming audio streams.
