Directional awareness audio communications system
Various embodiments include a directional awareness audio communication system and method. The system may include remote speaker/transmitting device(s) and listener/receiving device(s). The speaker/transmitting device(s) may send real-time location information with audio or separate from the audio to the listener/receiving device(s). The listener/receiving device(s) use the speaker/transmitting device(s) location information relative to the listener/receiving device location and orientation to perform audio processing on the transmitted audio signal. The listener/receiving device(s) provide the processed audio signal in stereo (i.e., at least two speakers such as left and right headphones, vehicle speakers, control center speakers, surround sound speakers, etc.) to a user of the listener/receiving device. The listener/receiving device(s) provides a warning and outputs standard audio if the real-time location information of the speaker/transmitting device(s) is unavailable or unreliable. In various embodiments, the listener device provides haptic and/or visual feedback of the speaker device location with respect to the listener device location.
