Hi, I think that the introduction of the lsp_look lookup array isn't ideal and found a better change that can be applied. in floor0_map_lazy_init() you can replace look->linearmap[W][j]=val; by look->linearmap[W][j]=vorbis_coslook(M_PI*val/look->ln); and in vorbis_lsp_to_curve you then replace float w=vorbis_coslook(wdel*k); ... }while(map[i]==k); by float w=map[i]; ...

I'm in the process of collecting performance data on my platform and I thought I'd test the difference between double and float performance. So, I replaced all occurances of double in vorbis with float (as was suggested should work). I ended up hanging at: #0 0x0002695c in cacm283 () #1 0x00026dd0 in vorbis_lpc_to_lsp () #2 0x0001b3cc in forward () #3 0x0001cac8 in forward () #4

Hi, I've downloaded the Speex-1.1.5 code and am trying to compile the Speexdec code using Microsoft VC++ 6.0 IDE. When I try to open the speexdec.dsw workspace, I get a dialog asking to locate the ogg_static file. I simply cancel that message, and then the project is opened in the VC++ 6.0 IDE. Now, when I simply try to compile the program, I receive this 5 error messages. error1.

(Disclaimer: this is not an LPC vs. LSP question) After looking at the Vorbis code I was wondering why you were using LSP to quantize the spectral envelope instead of simply quantizing the cepstrum (DCT(log(envelope))) or modified cepstrum (DCT(envelope.^alpha)). To me it seems like when the information is already in the frequency domain, there's no need to go back to LPC. Also, I think a DCT

All, Am running asterisk on an Opteron 165 with 4GB RAM and 1x80GB and 1x320GB SATA for a call center application (running VICIDIAL). Asterisk CLI (accessed by screen logging asterisk on startup and entering the allocated screen) gives me 'Warning LSP Low' and the voice quality goes down when this message pops up! That is, to start, we use: `/usr/bin/screen -L -d -m -S asterisk

Jean-Marc, Last week I tried the SVN code (build 11700) on the TI C55x DSP, and found that operation was broken again. I traced this to build 11522, committed on 5 June. The problem is in lsp.c, function lsp_to_lpc(). The line (lsp.c line 461 in build 11700): xin = 1<<(QIMP-1); /* 0.5 in QIMP format */ evaluates to zero. The following change corrects the problem: xin =

So, it turns out (and another implementation actually explicitly mentions it) that LSP->LPC computation using the FIR algorithm is very sensitive to noise (iterative algorithm) and really really requires doubles [we're not kidding]. This was complicating things for folks pursuing fixed point implementations, and also was a potential source for bugs if FP optimizations got out of hand. This

If you select an option that's not listed during ipv4/ipv6 setup it will accept it without verification. This corrects that behavior and forces a valid option to be picked. --- scripts/ovirt-config-networking | 106 +++++++++++++++++++++------------------ 1 files changed, 58 insertions(+), 48 deletions(-) diff --git a/scripts/ovirt-config-networking b/scripts/ovirt-config-networking index

Hello, You know, I always worry about the precision and the float constants... and there is a large lookup table in the floor1.c ... and I figure out a way to keep the code size and speed, but to improve the precision at this lookup table. (the difference is small, but audible) Here is the modifications in the floor1.c: tatic unsigned long FLOOR_fromdB_LOOKUP[256]={

Hi, Today I tried to run my player code with the CVS libvorbis (instead of RC3 as usual) and I found the infinite loop here (lines prefixed with >> are in the loop): tatic ogg_int64_t _get_prev_page(OggVorbis_File *vf,ogg_page *og){ ogg_int64_t begin=vf->offset; ogg_int64_t end=begin; ogg_int64_t ret; ogg_int64_t offset=-1; >> while(offset==-1){ >>

I'm trying to write a program that reads an ogg stream and check all the CRC values along the way. But I have big trouble with computing the checksum, or at least I never got checksums that match the one that is in the ogg file. I do set the CRC field in the header to 0 before calculating it. I start with 0 and have no xor at the end. I feed page header with all lacing values and the page

Just wondering if someone can help me out... I'm testing the core of my decoder filter (win32)... and when i get into this function: tatic void DecodeMVectors ( PB_INSTANCE *pbi,ogg_uint32_t SBRows,ogg_uint32_t SBCols ) The decoding mode is 0. When it attempts to do these lines.... pbi->FragMVect[FragIndex + 1].x = MVect[1].x;pbi->FragMVect[FragIndex + 1].y = MVect[1].y;

More information about the error below: I have downloaded the source and I got the same problem, but now I know in which exact line the error is. Inside the vorbisenc.c, we have the following function: tatic void codec_setup_partialcopy(codec_setup_info *ci, codec_setup_info *cs){ int i; memcpy(ci,cs,sizeof(codec_setup_info)); /* to get the flat numbers */ /* codebooks */

Hi all, Q1: The source defined this structure in the psy.h file: typedef struct{ int eighth_octave_lines; float preecho_thresh[4]; float postecho_thresh[4]; float preecho_minenergy; float ampmax_att_per_sec; int delaycache; } vorbis_info_psy_global; However, the file psytune.c makes this declaration: tatic vorbis_info_psy_global _psy_set0G={ 0, /*

It causes annoying artifacts in xmms

Could someone please try this version of bark_noise_median() on a x86 box? On my PPC box, this runs about 1.85x as fast as the current version, making the encoding speed about 6.5% faster (at least on my test case). The basic idea is to (a) avoid needless float/int conversions and (b) use multiplies instead of divides. I'm assuming (after having done some tests), that

-----BEGIN PGP SIGNED MESSAGE----- Hash: SHA1 Hi, I'm writing a simple application to decompress a set of Ogg files to raw PCM format, using vorbisfile, because that is the simplest way of doing it. These Ogg files are sounds for a game, and thus sometimes very short (about .25 s). However, vorbisfile has severe problems with Ogg files that are smaller than the CHUNKSIZE which is #defined
