Hi Ethan,
This looks interesting. Suppose I have a single tone sound getting mixed with
audio,
can we find that tone frequency and have an adaptive notch filter ?
Does your above equation works in identifying a fixed frequency tone ?
For example by doing (x(t) + x(t-2)) / (2*x(t-1)) can we
Any idea on finding mismatch in an audio signal ( music) given a reference
audio and a delayed
audio signal as inputs to the system. Correlation is the way to find, can we
rely on this method
for a music signal .Any other methods ?

From:
Not really, that will only work to find the frequency if the signal is a
pure sine wave, maybe with some very quiet noise. If you know roughly the
frequency where the sine wave is, it might still work if you put the signal
through a very narrow bandpass filter first. Or it might not if the sine is
