Digital audio communication and control in a live performance venue
In embodiments of the present invention improved capabilities are described for digitally transmitting audio that is converted from analog audio received from analog media pickup devices in a live performance venue by a stage box to a base unit over off-the-shelf twisted pair cable while sending pre-amplification control signals and power over the cable to the stage box. Audio for the performance venue is remotely managed from a virtual audio engineering mixing board that wirelessly communicates audio control commands to the stage box from a handheld computing device.
1. A stage box configured to improve audio signal quality comprising:
a circuit receiving a multiplexed digital media signal that comprises a first media signal multiplexed with a second media signal, the circuit further processing the multiplexed digital media signal, the processing causing the circuit to improve audio quality for a portion of the multiplexed digital media signal; and
wherein both the first and the second media signals are generated in part by one or more media pickup devices.
2. The stage box of claim 1 , wherein the processing causing the circuit to improve audio quality for at least one of the first media signal and the second media signal is responsive to a pre-amplifier action performed by a pre-amplifier circuit of the stage box on at least one of the first media signal and the second media signal.
3. The stage box of claim 1 , wherein each of the first media signal and the second media signal corresponds to a distinct analog signal.
4. The stage box of claim 1 , wherein the stage box further comprises an interface.
5. The stage box of claim 4 , wherein the interface is configured to provide remote control of at least one stage box function.
6. The stage box of claim 5 , wherein the at least one stage box function is a pre-amplification function and wherein a control setting for controlling the at least one stage box function is received through the interface.
7. The stage box of claim 6 , wherein the control setting is a gain value of the pre-amplification function.
8. The stage box of claim 1 , wherein the stage box further comprises an interface through which an analog signal is received.
9. The stage box of claim 8 , wherein the interface comprises an analog media pickup device interface and the stage box is further adapted to digitize the analog signal and multiplex the digitized analog signal with at least one of the first media signal and the second media signal.
10. The stage box of claim 1 , wherein the first media signal comprises an input multiplexed digital media signal that is received by the stage box and the second media signal is rendered from an analog signal by the stage box.
11. The stage box of claim 10 , wherein the analog signal is received by the stage box through a media pickup device interface thereof.
12. A method comprising:
generating a first digital representation of a first media signal;
multiplexing the first digital representation with a second digital representation of a second media signal thereby producing a multiplexed digital signal comprising a plurality of digital representations; and
processing a portion of the multiplexed digital signal to improve quality of the portion of the multiplexed digital signal.
13. The method of claim 12 , wherein each of the first digital representation and the second digital representation represents distinct analog media signals.
14. The method of claim 12 , wherein processing a portion of the multiplexed digital signal improves an audio quality of the first media signal.
15. The method of claim 12 , wherein processing a portion of the multiplexed digital signal improves an audio quality of the second media signal.
16. The method of claim 12 , wherein processing a portion of the multiplexed digital signal is responsive to a pre-amplification of at least one of the first media signal and the second media signal.
17. The method of claim 16 , further comprising receiving a remotely provided pre-amplification control setting and performing the pre-amplification responsive to thereto.
18. The method of claim 17 , wherein the control setting is a gain value for performing the pre-amplification.
19. The method of claim 12 , further comprising receiving the first media signal through an analog media pickup device interface.
20. The method of claim 12 , wherein the second digital representation comprises a multiplexed digital media signal of digital representations of a least two source media signals and wherein the multiplexing comprises multiplexing the first digital representation with the multiplexed digital media signal.
