packet loss concealment algorithm in speex speech codec
Hi, I am an engineering student in IIT Guwahati, India. Currently, as a summer project I am working on 'packet loss concealment in voip scenario'. I am eager to know what PLC methods are used at receiver end of speex decoder. And if I could develop some more efficient method I could able to contribute to the speex. Actually, I searched the whole speex manual but failed to find what

Attempting to shrink speex: Are these functions necessary?
for the bits init I am using speex_bits_set_bit_buffer and I don't use the write to or read from because the data is already in the buffer I am reading from and I am writing to the final buffer so I don't need to move arrays around. what part is the vocoder part of the decode? Thanks for your help! -Mike >>> Jean-Marc Valin <jean-marc.valin@usherbrooke.ca> 08/06/07

concealment
Hi, I'm a developer currently using the speex codec in a VOIP application of ours.. It sounds amazing, especially at wideband.. my question is how do I force it to do a concealment? We have a low latency application, and based on the current API, I'm guessing concealment only kicks in when a packet is lost.. However, our jitter buffer knows when a packet is missing, and I'd like to

PLC in Speex-
I've been working on improving packet loss concealment in my VoIP client -- I hadn't actually realized speex performed some PLC until I was looking at nb_decode(). There are two things I'd like to do, and I think both will require some modification to nb_decode() and nb_decode_lost(). - I'd like to have my frames overlap by some number of samples. This is intended to reduce the

Speex - frame size & packet loss concealment
Hi all, I am developing a VoIP application and have used SPEEX for that purpose; I successfully managed to port the codec in fixed-point to an ADSP-21364 processor, and the codec works fine in narrowband, wideband and ultra-wideband mode. Currently, I have chosen, in accordance with the speex manual, a 20 ms frame size in each of these modes: in other words, the input buffer for speex was set to

Packet loss concealment and G729
Hi Does anyone know where one can get hold of a G729 codec for asterisk which effectively can do packet loss concealment using Steve Kann's wonderful new Jitter buffer. The 2 versions that I know of, (digium's and the IPP one) do not perform great at PLC, especially with 4 or 5% loss. Thanks in advance. Clive

Why Rprofile.site is not built with manual installation of R devel in linux?
Hi all, I downloaded R-devel as explicited in https://developer.r-project.org/SVNtips.html Then, I tried to install it through instructions in https://cran.r-project.org/doc/manuals/r-devel/R-admin.html#Installation (taking into account also https://stat.ethz.ch/pipermail/r-devel/2016-May/072777.html) So: export REPOS=https://svn.r-project.org/R export RTOP=~ #adjust as necessary cd $RTOP svn co

operators as S4 methods
Dear all, I need to re-define some mathematical operators (+, *, /, etc) for an S4 class based on array. All references I have found (S Programming, Green Book) show how to define S3 methods for this (like in page 89 of S Programming for "-.polynomial"). What is the preferred S4 way for doing this? I hope I haven't missed some obvious piece of documentation. Many thanks, Iago

\link{} to help pages in Debian
Hello, In my Debian 3.0 systems, packages are installed in two different places, namely /usr/lib/R/library and /usr/local/lib/R/site-library, depending on whether they come from debian packages or CRAN ones. Help pages for my own packages, installed in the second location, cannot find help pages from, for example, the base package via \link{}. I also tried specifying the package with

I don't use term, but I've just tested it and this is reproducable. Is it a bug? Not sure. If you hit c after getting the message it will cancel the q() request.
