Method and system for dynamic audio stream redirection
There is provided a method of redirecting an audio stream from a first audio endpoint to a second audio endpoint in a computer operating system. The method includes directing the audio stream from a client application through a first audio resource stack to the first audio endpoint; creating an audio endpoint bridge to provide a path for the audio stream from the first audio resource stack through a second audio resource stack connected to the second audio endpoint; and redirecting the audio stream to the second audio endpoint using the audio endpoint bridge. The audio endpoint bridge can be created by forming a bridging application so as to activate the second audio stack. The bridging application can be hooked into a Windows audio engine in the second audio resource stack.
1 . A method for redirecting an audio stream from a first audio endpoint to a second audio endpoint in a computer operating system, the method comprising:
directing said audio stream from a client application through a first audio resource stack to said first audio endpoint;
creating an audio endpoint bridge to provide a path for said audio stream from said first audio resource stack through a second audio resource stack connected to said second audio endpoint; and
redirecting said audio stream to said second audio endpoint using said audio endpoint bridge.
2 . The method of claim 1 further comprising muting said first audio endpoint.
3 . The method of claim 1 further comprising enabling said audio stream to be outputted by said first audio endpoint and said second audio endpoint.
4 . The method of claim 1 , wherein said audio endpoint bridge is created by forming a bridging application so as to activate said second audio stack.
5 . The method of claim 4 , wherein said bridging application is formed by an audio processing object in said first audio resource stack.
6 . The method of claim 4 , wherein said bridging application is hooked into a Windows audio engine in said second audio resource stack.
7 . The method of claim 1 , wherein said computer operating system is Windows Vista.
8 . A system for redirecting an audio stream from a first audio endpoint to a second audio endpoint, the system comprising:
a controller configured to direct said audio stream from a client application through a first audio resource stack to said first audio endpoint;
said controller further configured to create an audio endpoint bridge to provide a path for said audio stream from said first audio resource stack through a second audio resource stack connected to said second audio endpoint; and
said controller further configured to redirect said audio stream to said second audio endpoint using said audio endpoint bridge
9 . The system of claim 8 , wherein said controller is further configured to mute said first audio endpoint.
10 . The system of claim 8 , wherein said controller is further configured to enable said audio stream to be outputted by said first audio endpoint and said second audio endpoint.
11 . The system of claim 8 , wherein said controller is further configured to create said audio endpoint bridge by forming a bridging application so as to activate said second audio stack.
12 . The system of claim 1 , wherein said controller is further configured to utilize an audio processing object in said first audio resource stack to form said bridging application.
13 . The system of claim 11 , wherein said bridging application is hooked into a Windows audio engine in said second audio resource stack.
14 . The system of claim 8 , wherein said computer operating system is Windows Vista.
15 . A system for redirecting an audio stream from a first audio endpoint to a second audio endpoint in an operating system, the system comprising:
a first audio resource stack for directing said audio stream from a client application to said first audio endpoint, said first audio resource stack comprising an audio processing object;
a second audio resource stack connected to said second audio endpoint bridge;
an audio endpoint bridge for redirecting said audio stream from said audio processing object through said second audio resource stack to said second audio endpoint.
16 . The system of claim 15 , wherein said audio processing object is configured to mute said first audio endpoint.
17 . The system of claim 15 , wherein said audio processing object is configured to enable said audio stream to be outputted by said first audio endpoint and said second audio endpoint.
18 . The system of claim 15 , wherein said audio processing object is configured to form a bridging application so as to activate said second audio stack, thereby creating said audio endpoint bridge.
19 . The system of claim 18 , wherein said bridging application is hooked into a Windows audio engine in said second audio resource stack.
20 . The system of claim 15 , wherein said computer operating system is Windows Vista.
