Historical question
Hello Jean-Marc and all,
I recently had a talk with somebody about CELP. He said, there is this
federal standard 1016 (4.8kbps) with a reference implementation of the
Department of Defense (only on Sun, unfortunately, if I got this right).
This one is noticed in the manual already.
He also said, since there is this implementation of the DoD, nobody
would voluntarily re-implement CELP.

Steganographic extension to Speex
Hello kind developers,
I am planning on creating a steganographic extension for speex/CELP.
Since speex/CELP is lossy, there should be quite many bits that one
can use for hiding data.
I'm familiar with the principles of CELP (two filter loops, one for
pitch, the other for formants, let the raw speech frame run through
those filter loops, take residue signal, map it on a codebook entry,

To CELP or not to CELP ... at higher bitrates
Jean-Marc,
I am building a tool for producing the highest possible quality Internet
interviews for "podcasting" applications. The goal is to produce a perfect
recording of an interview or conference -- and giving the participants a
glitch-free experience is secondary.
My approach, therefore, is to build a Windows "wave" file asynchronously by
using a streaming

Psycho Acoustic models i Speech Coding
(This is almost out of topic but anyway...)
It is surprising how little research effort have been put into psy-acou
models for CELP. The basic problem lies in that it is not easy to alter
the LP model without distroying the minimum-phase property (ie. the
stability of the predictor). That leaves us with psy-acou modelling of
the noise-part only. However, my own research is in constrained

To: speex-dev@xiph.org
Hello I'm working about audio and video codecs. I'm making a research about the state-of-the-art in coding technologies.
My question is about the speex codec 1.0. I would like to know the name of the algorithms that it uses.(LPC,CELP..). It uses more or less the same algorithm for narrowband and wideband?
Finally i would like to ask about future codec developement projects.
Thanks

reommended settings for low bitrate voicecom codec ?
Hello,
the voice-communication TeamSpeak (www.teamspeak.org) is currently testing a
version that supports speex codecs. The quality for high bitrates is quite
good.
BUT, the low-bandwidth speex codecs that are currently used arent very good.
What I did to find this out:
I comprared a speex AVB with 6.3 KBit/sec (total, overhead for packets and
stuff included) and the 6.3 Kbit/sec Celp Codec

Psycho Acoustic models i Speech Coding
Hi,
Does anyone have an idea about the possibility to apply psychoacoustic
models as the ones in mp3 or AAC to a CELP coder? Thanks!

persp graphs
Hi,
I am doing my way on R, with much experimenting. So, I am trying to plot a 3d
graphic ussing "persp" and entering a data set (attached) of UTM coordinates
as x,y and a pH values as z. However when I try an error message comes out
telling that increasing x and y values are expected. Jus ordering the first
vector does not help, and, of course, order the first two independently
