Binaural recording for processing audio signals to enable alerts
A wearable device for binaural audio is described. The wearable device includes a feedback mechanism, a microphone, an always on binaural recorder (AOBR), and a processor. The AOBR is to capture ambient noise via the microphone and interpret the ambient noise. An alert is issued by the processor to the feedback mechanism based on a notification detected via the microphone in the ambient noise.
1. A method for an always on binaural recording, comprising:
monitoring a background noise;
storing the background noise in memory;
filtering the background noise; interpreting the background noise by comparing the background noise to a catalogue of classified sounds stored locally to detect a notification; and
issuing an alert via a feedback mechanism based on the notification detected in the background noise, the alert to preserve directional information of the notification and to include a replay of the background noise stored in the memory.
2. The method of claim 1 , wherein the background noise is monitored via an Always On Binaural Recoding.
3. The method of claim 1 , wherein the filtering of the background noise improves a quality of the monitored background noise.
4. The method of claim 1 , wherein the feedback mechanism is a speaker, a vibration source, a heads-up display, or any combination thereof.
5. The method of claim 1 , wherein the catalogue of classified sounds is tailored for a particular context of use of a wearable device.
6. The method of claim 1 , wherein geo-tagging is used to determine the catalogue of classified sounds.
7. The method of claim 1 , wherein the alert is issued to a user based on a match between the notification and the catalogue of classified sounds.
8. The method of claim 1 , wherein the alert further includes a sound, a vibration, a displayed alert, or any combination thereof.
9. The method of claim 1 , wherein the directional information of the notification is determined using sound localization techniques at a processor.
10. The method of claim 1 , wherein the alert further includes a direction of a source of the notification.
11. A system for binaural audio, comprising:
a display;
a speaker;
a microphone;
memory to store an ambient noise captured by the microphone, the memory in circuit with the display and the speaker; and
a processor in circuit with the memory, the processor to execute instructions to:
capture the ambient noise;
interpret the ambient noise captured by the microphone by comparing the ambient noise to a catalogue of classified sounds stored locally to detect a notification; and
issue an alert via the speaker based on the notification detected in the ambient noise, the alert to preserve directional information of the notification and to include a replay of the ambient noise stored in the memory.
12. The system of claim 11 , further including stationary noise reduction circuitry to suppress sources of sustained noise.
13. The system of claim 11 , further including stationary noise reduction circuitry to suppress sources of sustained noise, emergency notifications to be excluded from suppression by the stationary noise reduction circuitry.
14. The system of claim 11 , wherein the alert is prioritized and delivered to a user based on priority.
15. The system of claim 11 , wherein the alert is prioritized and delivered to a user based on a user configuration.
16. The system of claim 11 , wherein the processor is to interpret a convolution that enables matching between the ambient noise and the catalogue of classified sounds.
17. The system of claim 11 , wherein the processor is to interpret the alert using a convolutional neural network.
18. The system of claim 11 , wherein the processor is to filter the ambient noise to produce an audio sample.
19. The system of claim 11 , wherein the processor is to determine the directional information of the notification using sound localization techniques.
20. The system of claim 11 , wherein the alert further includes a direction of a source of the notification.
