similar to: (small) bug in nb_decode?

Hi Jean-Marc, Hi Jim, I have also seen some problems with the 1.1.8 release on the C55x. So far I have boiled down the issues to the following: 1) We need our own "fixed_xx.h" header file. I don't know why, and haven't had time to investigate, but there is a definite improvement when I use the attached fixed_c55x.h file which has turned all the maths into inline functions.

Totally possible- this is the first time this has happened that I know of in many many hours of usage- On the other hand, this null check isn't in my code base and it was in nb_decode_lost, and nb_encode- so I figured it was just an oversight- Tom

hi, thanks for answers to my previous qns. have some more of them. hope it's ok to ask questions on the basics of CELP here. let me know if it's not. 1) synthesized filter stability after interpolation of LSFs I read from some resources that if LSF representation of LPCs is used for interpolation, stability of the synthesis filter is guaranteed. from another source, i read that the

Somewhere in the new packet-loss concealment code, there is a bug. I tried encoding a 44100-hz stereo file and it decodes just fine, but if I try it with packet loss, I get a segmentation fault. If you want to see the file, I can put it up somewhere publicly accessible. If someone here can't work on it, I'll be back on my home computer in a few days, so I'll work on it then.

I need to shrink speex so it will fit on an embedded processor along with some other code. The chip has only 20k of ram. I have done some work with libspeex.dsp by removing references to all modes but narrow band 8000 hz (submode 3). I used the defines: FIXED_POINT, DISABLE_FLOATING_POINT_API, DISABLE_VBR. I also removed the structures for the other submodes and the functions that they called.

Hi Jean-Marc, will you include these optimizations for minimal ram usage in the main version? Maybe if Peter sends a Patch...

I am studying the speex 1.0.5 C source code ,but i feel it is hard to understand the code ,especially the ltp.c and filters.c file. may you tell me the detail algorithm or the more detail notation of the source code of this two file.including below functions void open_loop_nbest_pitch(float *sw, int start, int end, int len, int *pitch, float *gain, int N, char *stack); float

Hi, After Bob fixed the two-address format of the ARM ldm/stm instructions, a problem remains. The load multiple instruction looks like: // A list of registers separated by comma. Used by load/store multiple. def reglist : Operand<i32> { let PrintMethod = "printRegisterList"; } def LDM : AXI4ld<(outs), (ins addrmode4:$addr, pred:$p, reglist:$dsts,

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, I currently have speex "working" in my project but the encode and the decode don't seem to be working like I would hope. I am using speex 1.2beta2 and I am trying to 16bit 8kbs narrowband. on the decode side I encoded a voice on a windows machine. I took the encoded information and transferred it over to the C54x project and decoded it and it didn't sound that great.

Hi list! There seem to be some oddities in using ABR. The first thing I notice is that because "abr_count" increases without bound, after a while the weight of the bitrate history will completely swamp any change in the current bitrate and the ABR adjustment will essentially stop happening. This seems to be true in any mode (not just UWB) and perhaps a solution is to cap

I would like to hear from some one who has ecb, multiple modes with ruby mode + html mode, rails mode all working together and playing well. I had ecb working with Ruby syntax highlighting. That was a no-brainer since I just had to apt-get them on my Debian Sarge box.

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
