Use of voice-to-remaining audio (VRA) in consumer applications
View Patent ↗Systems provide an audio/visual output to each of a plurality of listeners in a manner that permits individualized audio adjustment, wherein audio comprises a first signal that is substantially voice and a second signal that is substantially other than voice. The systems may include a video device, a storage medium, and a transmitter that transmits the first and second signals to a plurality of personal listening devices. Each of the plurality of personal listening devices may include first and second receivers, first and second adjustment devices, an audio signal combining device, and one or more transducers, wherein the systems permit each of the plurality of listeners to adjust the first and second signals independently of other ones of the plurality of listeners in an audience.
1. A personal listening device useful in a listening environment having a plurality of listeners, the personal listening device comprising:
a receiver configured to receive a first audio signal and a second audio signal, the first audio signal including substantially a voice signal and the second audio signal including a remaining audio, the first audio signal being different than the second audio signal;
an adjustment device configured to allow a listener to adjust the first audio signal and the second audio signal independent of each other; and
a transducer configured to receive the adjusted first and/or second audio signals, combine the received first and second audio signals, and output an audible sound based on the combined first and second audio signals to the listener without interfering with other listeners in the listening environment.
2. The personal listening device of claim 1 wherein the personal listening device is chosen from a group consisting of a headphone, a hearing aid, an assisted listening device, a cochlear implant, an eyewear, a wearable computer, or a combination thereof.
3. The personal listening device of claim 1 wherein the receiver is chosen from a group consisting of Digital Theater Sound (DTS) receiver, Sony Dynamic Digital Sound (SDDS) receiver, Dolby Digital receiver, and other multi-channel format decoder.
4. The personal listening device of claim 1 wherein the second audio signal comprises a combination of left, right, left surround, right surround, center, and subwoofer analog outputs.
5. The personal listening device of claim 1 wherein the first audio signal and the second audio signal comprise digital signals that require decoding.
6. The personal listening device of claim 1 wherein the adjustment device is configured to adjust the second audio signal and a sum of the first audio signal and the adjusted second audio signal.
7. The personal listening device of claim 1 wherein the adjustment device is configured to adjust:
a balance between the first and second audio signals, and
a balanced combination of the first and second audio signals.
8. The personal listening device of claim 7 wherein the balance adjustment is based on a sum of:
a ratio of actual and stored values of a first audio signal standard deviation, and
a ratio of actual and stored values of a second audio signal standard deviation.
9. A broadcasting apparatus, comprising:
a storage medium holding a first audio signal and a second audio signal corresponding to the first audio signal, the first audio signal including substantially a voice signal and the second audio signal including a remaining audio; and
a transmitter configured to transmit the first and second audio signals to a plurality of receivers, wherein the first and/or second audio signals are configured to be independently adjusted at each of the plurality of receivers and subsequently combined to produce an audible sound.
10. The broadcasting apparatus of claim 9 , further comprising a personal listening device chosen from a group consisting of a headphone, a hearing aid, an assisted listening device, a cochlear implant, an eyewear, a wearable computer, or a combination thereof.
11. The broadcasting apparatus of claim 9 wherein the receivers are chosen from a group consisting of Digital Theater Sound (DTS) receiver, Sony Dynamic Digital Sound (SDDS) receiver, Dolby Digital receiver, and other multi-channel format decoder.
12. The broadcasting apparatus of claim 9 wherein the second audio signal is a combination of left, right, left surround, right surround, center, and subwoofer analog outputs.
13. The broadcasting apparatus of claim 9 wherein the first audio signal and the second audio signal are digital signals that require decoding.
14. The broadcasting apparatus of claim 9 wherein the adjustment comprises adjusting the second audio signal and adjusting a sum of the first audio signal and the adjusted second audio signals.
15. The broadcasting apparatus of claim 9 wherein the independent adjustment comprises:
adjusting a balance between the first and second audio signals, and
adjusting a balanced combination of the first and second audio signal.
16. The broadcasting apparatus of claim 15 wherein the balance adjustment is based on a sum of:
a ratio of actual and stored values of a first audio signal standard deviation, and
a ratio of actual and stored values of a second audio signal standard deviation.
17. A personal listening device useful in a listening environment having a plurality of listeners, the personal listening device comprising:
means for receiving a first audio signal and a second audio signal, the first audio signal including a voice signal and the second audio signal including a remaining audio, wherein the first audio signal is different than the second audio signal;
means for adjusting the first audio signal and the second audio signal independent of each other by a listener; and
means for receiving the adjusted first and/or second audio signals, combining the received first and second audio signals, and outputting an audible sound based on the combined first and second audio signals to the listener without interfering with other listeners in the listening environment.
