similar to: Echo canceller problem

? hi all, i am using the Acoustic Echo Cancellation from "Speex 1.1.12 version" in my VOIP application. Is it that the frame length to be chosen should always be 20ms or can i have flexibility in chosing the frame lenght? on what parameters does the frame length choise depends? thank you all, Shri. -------------- next part -------------- An HTML attachment was scrubbed...

Hi All, I am working on my master project to port the Speex Acousic Canceller to FPGA. But I am not able to get a satisfied result in its performance whenI integrated it to a SIP softphone as my first step. The SIP softphone calls to a PSTN gateway and lands to my land line phone. I can hear the echo of my every word while I talks on the land line phone. I am using G.711 codec, frame_size 80

I have working copies of code in development on multiple places - work machine, home machine, laptop, etc. I can''t always force these machines to use the same credentials; I end up with each machine having slightly different database.yml configurations. With Subversion-Pre-Capistrano, I left the entire config directory out of Subversion (or some kind of template; see

Hi all, If you are using Pound / Pen or another load balancer, I believe you should read this: http://blog.teksol.info/articles/2006/08/25/subversion-metadata-exposure-on-mongrel My article refers to Dan Benjamin''s http://hivelogic.com/articles/2006/04/30/preventing_svn_exposure My point is that even though we are preventing Apache from serving anything except a select few file

I have experienced this with a svn 1.5 client but not with 1.4.6. Did anybody see this with a 1.4.6 (or older) client? Btw. what is the server version? Anyway this seems to be a bug in subversion.

Hi everyone, I've just released Speex 1.1.9. The main change in this release is the echo canceller work sponsored by Tipic Inc (http://www.tipic.com/). It is now possible to do acoustic echo cancellation and obtain good attenuation after a short adaptation time. This has been tested at 8 kHz, but it should also work at 16 khz and above, so give it a try. There were also some fixes to the

Jean-Marc, I have traced the second infinite loop further. When st->adapted becomes true (mdf.c line 623), the first Yf[i] value is 4, the leak_estimate is 0xd4e, the resulting r is 3. The first value in st->Rf is 0, so e is 1, and r is set to e>>1, or 0. A little later there is a divide by r, and there is the hang. It seems that the 0 in Rf[0] is the problem, but I am not

I''m using the Shovel recipe to deploy my lovely app to text drive. everyhting seems to be ok apart from the deploy action which fails saying that there is "No such file or directory" I''ve included the full error listing below. The SVN definately exists because we''re using for development. Does any one have any ideas what might be going wrong? Thanks Tom

I installed TortoiseSVN, created a local repository at c:/instantrails/SVNRepository. I have an app that I want to put into SVN and also do a freeze_edge for, but I''m not sure how. I ran command ''rake freeze_edge'' and got the error: ERROR: Must have subversion (svn) available in the PATH to lock this application to Edge Rails rake aborted! Any advice or links to a

So R is on subversion right? So why doesn't somebody authoritative get r-project.org on the subversion testimonials page? http://subversion.tigris.org/testimonials.html Just a suggestion. -- Charles Geyer Professor, School of Statistics University of Minnesota charlie@stat.umn.edu

It looks like the Subversion migration is working. The CVS repository is still there, but in read-only mode. However, the SVN repository preserves the version history of the CVS repository, albeit organized slightly differently. For an introduction to Subversion, this online book is essential: http://svnbook.red-bean.com/ It is written by some of the Subversion authors. The only drawback I

Hello, I'm trying to use speex for implementing a VoIP demo application using linphone on an embedded system. At the moment I'm not really able to do real time encoding, and thinking about making an assembler port for speex to the AVR32 architecture. The AVR32 is a new hybrid MCU/DSP fixed point processor running at 120Mhz in my application. Does anyone have experiences/info about the

I'm trying to use speex on OMAP's DSP using dsp gateway, and have some questions. The code almost works (within few next days I'll post a some kind tutorial and patches), but it seems to be a little bug in bits.c. The code looks like this void speex_bits_read_from(SpeexBits *bits, char *chars, int len) { ////////////////// bla-bla-bla /////////////////// for (i=0;i<len;i++)
