Hello, I recently measured the distances ndist[0][nb_subvect-1] which are used to make the decicion, which codebook entries are to be used in libspeex/cb_search.c (function split_cb_search_shape_sign). For that I took a couple of audio books (all german speech), downsampled the tracks to 8kHz and encoded them with "speexenc -n --bitrate 15000 ..." (I used svn revision 11825). Usually,

Hello, I do test runs of speex using speexenc -n [name].wav [name].spx The wav-files (6 different speech files) hereby are sampled at 44100Hz. Most interestingly, all Frames have SubModeID 5. I haven't tracked the Assignment of the SubModeID through the source code, so I just wanted to ask, if I can assume "speexenc -n" to use SubModeID 5 always? Ciao, Bj?rn -- You will

Hello, just to make sure I haven't gotten anything wrong: In cb_search.c (function split_cb_search_shape_sign) after all that searching nb_subvect CB entries are being written into the stream. These are all taken from the same codebook. If I wanted to, I could just change their order, couldn't I? Because important is only the linear combination of them all together, which I keep

Hi, Jean-Marc Valin wrote: > Not sure I understand your question. Change the order of what within what? In cb_search, we iterate nb_subvect times over a codebook, finding nb_subvect codebook entries to quantize the excitation signal. After finding these nb_subvect codebook entries, they're written into the stream: /*save indices*/ for (i=0;i<nb_subvect;i++) {

Bj?rn, I would be very interested in looking at your data and the R file. Actually, I think a lot of people would. You might want to post it on a website...

Hi, I noticed that, when working with R on a command line, I cannot enter anything into the command line which is longer than 1023 characters. If I input sth longer, it'l be just cut off at this lenght, and a "+" will be presented to me on the command line. It's not as bad since I can copy'n'paste commands longer than this with newline characters in between onto the

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

Hello, Is it possible to adjust the level of the denoiser ? In an old beta, before you change the aggressiveness of the denoiser, it works very well with the noise of a car, a road etc... but not now. The AEC too works very well in a old beta, but now, I think there is a problem... I have tested it with the same sound card (WB 16000). In any case, your project is the best VOIP library in this

So you're suggesting, I can either write into the stream: -

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

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. If I read

Hello, I just checked out the latest version of speex and I want to compile it. The INSTALL file says that's easy: bjoern@deimos:~/studium/beleg/resources/svn/speex$ cat INSTALL Installing Speex is as easy as: % ./configure [--prefix=<install-path>] % make % make install Note that if you are using the code from SVN, you will need to run "autogen.sh" instead of
