...eed enough data in order to get a good S/N. I compute the cross-correlation between 1.5 second data of each signals. In this way the application detection of any anomalies is quite slow. I am looking for something faster, but I fear it will be something very application dependent.

...he application. I confirm that I am not re-initializing the echo state after the session starts. Is this normal? Is there any way I can keep the echo state to what it was when the participant not speaking. Also, any pointers on why I get a feeble echo back would be greatly appreciated. Thanks, Elston

...that I start in perfect sync. When I run echo canceller on the first stream there is perfect echo cancellation and on the second stream the echo is subdued. The echo is not very audible unless you listen at high volume. Although this is acceptable, I would like to know if you see similar issue. -Elston -----Original Message----- From: Marco Pierleoni [mailto:pierleoni.m at gmail.com] Sent: Tuesday, May 11, 2010 7:30 PM To: Elston Sa Cc: speex-dev at xiph.org Subject: Re: [Speex-dev] AEC - Echo is cancelled however..... 2010/5/11 Elston Sa <jose at rebaca.com>: > Is there an API in s...

Is there an API in speex or have you implemented your own? I am currently trying to find one.

...sure why it keeps repeating every time the user stops / pauses and starts speaking again in a single session. I am using a laptop with standalone speakers. For echo cancellation to work one has to make sure that the ref and echo buffers are synchronized. I guess this is the most common problem. -Elston -----Original Message----- From: Anton A.

Marco, Thank you for your response. Is there a way I can determine if the synchronization is perfect or not?

I''m trying to pull ou the ''name'' field for each of my associated rows and pass it as a string of names. I''m missing something obvious here but I thought @bag.packages.name.join(", ") would work. do I have to loop through @bag.packages? that seems like the long way. thanks -zac -- Posted via http://www.ruby-forum.com/.

after playing with the DB interaction I''m moving on to doing some file IO. but I''m completly lost as to where to put the code and how to call it. I''m trying to get a list of files in a directory and it''s not obvious to me how to do this in Rails via a controller method. so ruby code is Dir.entries("testdir").last and html code is <%=

Dear list members, I want to fit a nonlinear mixed model using the nlme command. My dependent variable takes the form of event counts for different countries over a number of years, and hence I was going to fit a mixed effects negative binomial model. The problem, as far as I can glean from Pinheiro & Bates 2000, is that I need a model that is not normal in the errors. All the models they

I''ve just started getting so odd symptoms working with webrick. I use TextMate editing my rails apps over a CIFS mount on the server. Usually when I "edit/save/reload" a page I see the new changes. However I''ve started getting the same old data and now have to frequently restart the webrick server to get my changes to render. What is available to debug on this to

I''ve demoed my rails app and now have to move it to a MSSQL DB. the big problem I''m running into is the table name conventions I have to use. I have to use names like tbl_Transfer & tbl_User.

So I got my rails app to connect to the SQLServer via ODBC, and I can model/scaffold, yada yada.. but when I need to exec a stored proc using sql_server.rb I get undefined local variable or method `connection'' how can that be, if I can connect for everthing else? thanks -- Posted via http://www.ruby-forum.com/.

I''ve rewritten my kickstart cgi in rails with DB acces to the host list and the testing is perfect. I can send the macaddress in the HTTPrequest Header, rails looks up the macaddr in the machine db and spits back out a kickstart file for the machine.. however in real world usage what I get is a request for http://server//kickstarts/kickme which rails fails with 192.168.20.176 - -
