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,

Increasing the speed of speex playback
You're asking the wrong question. The question is not "why does it would bad with Speex?", but "why does it sound good with LPC10 and MELP?". And the answer is that both are vocoders. Try dropping frames/subframes with anything else (Vorbis, MP3, G.729, u-law, ...) and it'll sound terrible as well. The only reason it sounds good with vocoders is because the

Exc CB Search very little Question
Hi, Jean-Marc Valin wrote: > Well, you could change the order in the encoder as long as you reverse > it in the decoder as well. Ok, I see that in the split_cb_shape_sign_unquant function, that each coefficient is tied to it's position in the nb_subvect exc coefficients. Honestly, I have problems understanding what exactly the codebook search works like. If you have the time to to

Determining length of speex file speech
Hello, I would like to run a script over a speex file which determines, how long the speech contained in the speex file is. So I run through the ogg file, skip the first two ogg _pages_ (speex header and comment header, both contain IMHO only 1 ogg _packet_), and then count in any ogg page the number of the ogg _frames_ (which, unless I used -nframes while encoding, which I did not), and multiply

I've already tested my decoder with the options -0 to -8 and it works, but the streams doesn't contain any verbatim or constant subframes. I guess this depends heavily on the input

Increasing the speed of speex playback
Hi, Jean-Marc, and thanks for the quick reply. Let me just say I'm a huge fan of speex, and the work you've done. I actually barely understand what I'm reading so far in the source code and documentation, just enough to understand just how cool the algorithms are. LPC10 and MELP allow me to speed up speech with a simple hack on the decoder frame size. Playing fewer samples per

Coalesce function in BBmisc, emoa, and microbenchmark packages
Hello All, Need to coalesce some columns using R. Looked online to see how this is done. One approach appears to be to use ifelse. Also uncovered a coalesce function in the BBmisc, emoa, and microbenchmark packages. Trouble is I can't seem to get it to work in any of these packages. Or perhaps I misunderstand what it's intended to do. The documentation is generally pretty scant. Working

Firefox fails to authenticate .mil sites with New DoD CAC
Can anyone help with getting the new DoD CACs (Smart Card) to work in CentOS 6.6? I don't use it for console logins, only for email and .mil web sites. I recently had to get a new DoD CAC (Smart Card) when one of the buildings I work in upgraded their security system. My old CAC was working fine prior to this for signing and encrypting email and for authenticating to various DoD (.mil) sites

SIP invite timeouts : how is someone sending invites from our server ??
I've been getting a lot of timeouts on non-critical invite transactions. I turned on sip debug. They were the result of SIP invites like this: Retransmitting #10 (NAT) to 185.107.94.10:13057: SIP/2.0 401 Unauthorized Via: SIP/2.0/UDP 215.45.145.211:5060;branch=z9hG4bK-524287-1---zg4cfkl50hpwpv4p;received=185.107.94.10;rport=13057 From:

uwb bitrates
Hello I just wrote a little application using speex. I am compressing and packing singel frames to transmit them. Now I read in the manual, that it's possible to achieve higher bit rates by packing more than one frames at once. Unfortunately there is no table included at the manual, that shows the "real" bitrates of ultra wide band mode. So my question is: Can someone provide that

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
