Uh , but , you know , it 's  that  that  that 's tricky to do. It has mistakes. Uh , and if you 've got enough time , uh , this other method appears to be somewhat more reliable. Uh , a variant on that for just determining signal - to - noise ratio is to just , uh  you can do a w a uh  an iterative thing , EM - like thing , to determine means only. I guess it is EM still , but just  just determine the means only. Don't worry about the variances.
Mm - hmm.
And then you just use those mean values as being the  the , uh uh signal - to - noise ratio in that band.
But what is the  it seems like this kind of thing could add to the latency. I mean , depending on where the window was that you used to calculate  the signal - to - noise ratio.
