Abstract

Claims (30)

1. A digital audio mixing system for real time mixing and adjustment of audio signals during a live performance on a live performance stage, the system comprising:

a. a host computer having a processor configured to perform digital audio mixing functions which controls selected audio parameters including the relative volume levels of audio signals for a plurality of inputs and a plurality of outputs in response to mixing control signals for controlling the selected audio parameters;

b. an audio patch bay unit coupled to the processor, the patch bay unit having a plurality of inputs, the inputs adapted to receive audio signals from a plurality of different live audio source components and a plurality of outputs adapted to transmit audio signals to a plurality of audio destination components wherein the patch bay unit configures the connections between the inputs and the outputs;

c. a system console configured to generate and transmit the mixing control signals to the processor, the system console comprising at least one touch sensitive display and at least one tactile control surface having audio faders;

d. a system user interface, the user interface comprising software which directs the host computer to generate multiple functional views on the display; the multiple functional views including a stage view; and

e. the stage view comprising a plurality of different pre-defined and user selectable icons on the display, each of the icons visually representing different types of the audio source and destination components connected to the system, the icons movable by the user on the display to positions representing actual stage locations on the live performance stage of the stage elements corresponding to the icons, and a plurality of user selectable stage element configuration presets, the presets including a predefined selection and arrangement of audio source and destination components,

f. wherein the software configures the system user interface to control the audio patch bay unit so that the user can select multiple ones of the inputs and reconfigure the connections between the selected inputs and one or more of the outputs to define one or more user selected mixes of audio signals from said live audio source components; and

g. wherein the software configures the system user interface to receive user input commands in real time during a the live performance to select an audio signal from one or more of said live audio source components by touching or pointing to one or more icons on the stage view representing said one or more live audio source components, and to receive user input commands real time during the live performance to adjust multiple audio parameters, including the relative volume levels, related to the one or more live audio source components by selecting multiple audio parameters of the selected signal and then adjusting the multiple selected parameters.

2. The system of claim 1 , the user interface further comprising a setup view, the setup view comprising a virtual patch by table of system inputs and input audio properties associated with each input, each of the inputs having user-assignable user-friendly names, the user-friendly names representing different stage elements assignable by the user to the input.

3. The system of claim 2 wherein the virtual console view includes an array of touch screen faders.

4. The system of claim 3 wherein the touch screen faders are arranged in channel strips having multiple audio channels to visually simulate a non-virtual mixing console.

5. The system of claim 4 wherein the each of the channels in the channel strips includes an EQ control icon, a pan control icon for bringing up a pan control window, a sole mode toggle configured to mute all other system audio sources, a mute toggle configured to mute the audio source corresponding to that channel, a text display of all insert effects for the corresponding audio source, a VU and margin display, a trim fader, and a text display of the name of the corresponding audio source component.

6. The system of claim 4 , the user interface further comprising a mixer functions view, the mixer functions view comprising a pan control window and an EQ control window.

7. The system of claim 6 wherein the virtual console view and mixer function view each include a cute view window, the cute view window displaying the icons selected and arranged by the user to represent the types and locations of the audio source and destination components on stage.

8. The system of claim 7 , the cute view window further comprising a visual display of audio parameters associated with an audio source represented on the display.

9. The system of claim 3 , the user interface further comprising a drum editor view.

10. The system of claim 3 , the setup view further comprising user selectable, pre-defined show setup configurations.

11. The system of claim 10 , the setup configurations including venue-type configurations and performance-type configurations.

12. The system of claim 1 , the user interface comprising selectable between an advanced user interface mode and a simplified user interface mode which reduces the complexity of the advanced user interface mode for an unsophisticated user.

13. The system of claim 1 , the stage view further comprising at least one user definable adjustment icon, the adjustment icon programmed to automatically implement pre-defined audio parameter adjustments associated with a pre-defined stage element.

14. The system of claim 1 , further comprising at least one stage box linked to the host PC wherein the stage box can configure the connections between a plurality of stage box inputs and a plurality of stage box outputs.

15. The system of claim 14 wherein the host PC, stage box, and stage elements are linked by a universal digital audio link wherein the universal digital audio link interconnects the host PC, the stage box, and the stage elements, on a universal network.

16. A method of digital audio mixing comprising:

a. providing a host computer having a processor that performs digital audio mixing functions which controls selected audio parameters, including the relative volume levels, of audio signals for a plurality of inputs and a plurality of outputs in response to mixing control signals for controlling the selected audio parameters;

b. providing an audio patch bay unit coupled to the processor, the patch bay unit having the plurality of inputs, the inputs adapted to receive audio signals from a plurality of different live audio source components and the plurality of outputs adapted to transmit audio signals to a plurality of audio destination components wherein the patch bay unit configures the connections between the inputs and the outputs in response to mixing control signals for controlling the connections;

c. providing a system console that enerates and transmits the mixing control signals to the processor, the system console, comprising at least one touch sensitive display and at least one tactile control surface having audio faders;

d. providing a system user interface, the user interface comprising software that directs the host computer to generate multiple functional views on the display; the multiple functional views including a stage view and a virtual console view;

e. wherein the stage view comprises a plurality of different pre-defined and user selectable icons on the display, each of the icons visually representing different types of the audio source and destination components connected to the system, the icons movable by the user on the display to positions representing actual stage locations on the live performance stage of the stage elements corresponding to the icons, and a plurality of user selectable stage element configuration presets, the presets including a predefined selection and arrangement of audio source and destination components;

f. controlling the audio patch bay unit and selecting multiple ones of the inputs and reconfiguring the connection between the selected inputs and one or more of the output to define one or more user selected mixes of audio signals from said live audio source components; and
