Can someone check my logic on this? It sounds simple but I'd appreciate
someone confirming what I'm trying to do.

I have CD-quality streaming audio digitized at 44.1 ksamples per second,
16-bit samples.

I also have an approx 10 msec duration recorded segment of the same audio,
in the same digital format as above.

I'm shifting the digitized streaming audio in real time into a comparator
and looking for a data match between my sample and the streaming audio.

Question: What is the maximum theoretical time lag before a match can be
detected, ignoring quantization noise and processing time? Is it one-half
the sample period or some other value?

Thanks for your help.
