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 togeth...

I am using speex on a Philips LPC2138 Arm 7 processor and have hit two compiler warnings when using FIXED_POINT and the Arm 4 asm code. In cb_search.c get a warning on the call to compute_weighted_codebook of: "passing arg 2 of 'compute_weighted_codebook' from incompatible pointer type' In cp_search_arm4.h it is defined as: static void compute_weighted_codebook(const signed char *shape_cb, const spx_sig_t *r, ..... but in cb...

And the main point of interest is the following: how much difference in SPEEX terms would it be if it were developed with ACELP in mind?

Hi, I have some questions regarding Speex. please reply as soon as possible. where are the two filter loops applied to the raw signal? where is the residue (innovation) signal calculated? where is the innovation mapped on a codebook entry (key)? which bits of a transmitted frame are the two filters, which are codebook keys? Is the codebook from the beginning on static (so already known by

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, the distances are in average 7.544420 and the deviation of t...

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++) { ind[i]=nind[0][i]; speex_...
