audio channel, the time between the detections of the sample
streams is measured, and one of the signal sample streams is
delayed based on the time measured between the detections.
Representative independent claim 1 is reproduced as follows:
1. A method for actively characterizing the latency of an
audio channel of a computer, comprising:
creating at least two signal sample streams for a waveform
in the 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;
measuring the time between the detections of the signal
sample streams; and
delaying at least one of the signal sample streams based, at
least in part, on the time measured between the detections.
The examiner relies on the following references:

Claims 1-10, 12-14, 16, 17 and 19-24 stand rejected under
35 U.S.C. § 103. As evidence of obviousness, the examiner offers
Vahatalo with regard to independent claims 1, 12, 19 and 22,
adding Park with regard to claims 2-4, 7-10, 16 and 17. With
