Method and apparatus for active latency characterization
First Claim
1. A method for actively characterizing the latency of an audio channel of a computer, comprising:
- creating at least two signal streams for a waveform in said audio channel;
detecting the presence of the first signal sample stream for said waveform and the second signal sample stream for said waveform at a point in said audio channel; and
measuring the time between the detections of the signal sample streams.

Abstract
Briefly, in accordance with one embodiment of the invention, a method for actively characterizing the latency of an audio channel of a computer, such as a personal computer, is provided. At least two signal streams for a waveform are created in the audio channel. The presence of the first signal sample stream for the waveform and the second signal sample stream for the waveform is detected at a point in the audio channel. The time between the detections of the signal sample streams is measured.
Briefly, in accordance with another embodiment of the invention, a method of actively characterizing the latency of an audio channel of a computer, such as a personal computer, is provided. At least a first and a second waveform are created in the audio channel. The presence of the first and the second waveform are detected at a point in the audio channel. The time between the detections of the waveforms is measured.
