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.
Claims23
A system comprising:
- a bi-directional audio communication device communicatively coupled with a plurality additional bi-directional audio communication devices, wherein the bi-directional audio communication device comprises:
- a plurality of incoming audio connectors, each of the plurality of incoming audio connectors configured to receive an incoming audio stream from at least one of the plurality of additional bi-directional audio communication devices;
- and
- an audio processing unit configured to apply unique head-related transfer functions (HRTFs) to the incoming audio stream received from each of the plurality of incoming audio connectors to produce a left audio output and a right audio output that positions each of the incoming audio stream received from each of the plurality of incoming audio connectors at different spatial locations;
- and
- a left speaker and a right speaker communicatively coupled to the bi-directional communication device, the left speaker and the right speaker operable to convert and output the respective left audio output and right audio output as binaural sound.
