Abstract

A method and system for daisy chaining tournament audio controllers, where the method comprises, in a headset coupled to a first audio controller, the first audio controller being in a daisy chain of audio controllers: receiving a chat signal from a second audio controller in the daisy chain of audio controllers, receiving a microphone signal from a microphone in the headset, summing the chat signal with the microphone signal, communicating the summed signal to a third audio controllers in the daisy chain, and communicating the chat signal to the headset. The microphone signal may be removed from the summed chat signal and microphone signal by adding a second microphone signal 180 degrees out of phase with the microphone signal. The chat signal may be summed with the microphone signal at an amplitude set by a user of the headset after the removal of the microphone signal.

First claim

What is claimed is:

1. A system, the system comprising:
a first audio device comprising a microphone and a first audio processor, wherein the first audio processor is configured to:
generate a first chat signal by summing a second chat signal with a microphone signal from the microphone;
receive the second chat signal from a second audio processor of a second audio device;
transmit the first chat signal to the second audio processor, when the first audio device is at an end of the daisy chain; and
transfer a third chat signal from a third audio processor, of the third audio device, to the second audio processor, when the first audio device is not at the end of the daisy chain.

2. The system of claim 1 , wherein the first audio processor is operable to remove the microphone signal from the first chat signal by subtracting the microphone signal.

3. The system of claim 2 , wherein after the removal of the microphone signal from the first chat signal, the first audio processor is operable to sum the chat signal with the microphone signal at an amplitude set by the headset to generate a scaled chat signal.

4. The system of claim 3 , wherein the first audio processor is operable to communicate the scaled chat signal.

5. The system of claim 1 , wherein a chat loop switch is coupled to two summers, each of which is coupled to a separate terminal of the microphone.

6. The system of claim 1 , wherein the first audio processor is operable to sum a signal from a gaming console with the first chat signal.

7. The system of claim 1 , wherein each audio device in the daisy chain is operably coupled to the first audio device.

8. The system of claim 7 , wherein the first chat signal comprises audio from each audio device in the daisy chain.

9. The system of claim 1 , wherein the microphone signal is a balanced signal.

10. The system of claim 1 , wherein the first audio processor is operable to convert the second chat signal from a differential signal to a single-ended signal while being summed with the microphone signal.

11. A method for processing audio signals, the method comprising:
in a first audio device comprising a first audio processor in a daisy chain of audio processors:
generating a first chat signal by summing a second chat signal with a microphone signal;
receiving the second chat signal from a second audio processor in the daisy chain of audio processors;
receiving the microphone signal in the first audio device;
communicating a third chat signal from a third audio processor to the second audio processor in the daisy chain, if the first audio processor is not at an end of the daisy chain of audio processors; and
communicating the first chat signal to the second audio processor, if the first audio processor is at an end of the daisy chain.

12. The method of claim 11 , comprising removing the microphone signal from the first chat signal by adding a second microphone signal 180 degrees out of phase with the microphone signal.

13. The method of claim 12 , comprising after the removal of the microphone signal from the first chat signal, summing the first chat signal with the microphone signal at an amplitude set by the first audio device to generate a scaled chat signal.

14. The method of claim 13 , comprising communicating the scaled chat signal.

15. The method of claim 11 , wherein a chat loop switch is coupled to two summers, each of which is coupled to a separate terminal of a microphone.

16. The method of claim 11 , comprising summing a signal from a gaming console with the first chat signal.

17. The method of claim 11 , wherein each audio processor in the daisy chain of audio processors is coupled to the first audio device.

18. The method of claim 17 , wherein the first chat signal comprises audio from each of the audio processors in the daisy chain.

19. The method of claim 11 , comprising converting the second chat signal from a differential signal to a single-ended signal while being summed with the microphone signal.

20. A system for processing audio signals, the system comprising:
a first audio device coupled to a first audio processor, the first audio processor being in a daisy chain of audio processors, the system being operable to:
receive a chat signal from a second audio processor in the daisy chain of audio processors;
receive a microphone signal in the first audio device;
sum the chat signal with the microphone signal;
communicate a different chat signal from a third audio processor to the second audio processor in the daisy chain, if the first audio processor is not at an end of the daisy chain of audio processors;
communicate the summed chat signal and microphone signal to the second audio processor, if the first audio processor is at an end of the daisy chain; and
sum the chat signal with a signal from a gaming console and a second microphone signal 180 degrees out of phase with the microphone signal.
