...al talk > SPEEX_PREPROCESS_SET_ECHO_SUPPRESS_ACTIVE: echo suppression in double-talk Yes, I am aware of these parameters and are familiar with how they affect the gain. However they do not affect the timing of speech switching very much. The important parameter for the speech switching is the Pframe. Pframe is as you know based on the SNR estimation. However when the near-end signal is low compared to the far-end signal (coming from the close speaker element) the SNR is not distinctly increased when near-end talks. > Can you explain what ... problem you've encountered?

Hello, I have some data covering contaminant concentrations in fish over a time period of ~35 years. Each year, multiple samples of fish were taken (with varying sample sizes each year). Ultimately, I want an estimation of the variance between years, and the variance within years + random effects. I used a linear mixed model to estimate these variances, but after reading a number of different

How can you tell that the residual echo estimation is reliable? in any case, I suspect that the whole Pframe idea might have to be revised (i.e. computing it completely differently or even not having a Pframe at all)....

Hi, I'm wondering if the Dirac granulepos parsing in liboggz and display in the oggz tools is currently correct, as I'd like to do a release of these soon. A couple of days ago David Schleef mentioned there were some problems. David, is that currently true (ie. since David Flynn's recent updates to support Dirac), and if so could you please explain what the problems are, or point me

Dear Masters, first I'd like to wish u all a great 2011 and happy holydays by now, second (here it come the boring stuff) I have a question to which I hope u would answer: I run a logistic regression by glm(), on the following data type (y1=1,x1=x1); (y2=0,x2=x2);......(yn=0,xn=xn), where the response (y) is abinary outcome on 0,1 amd x is any explanatory variable (continuous or not)
