similar to: FLOAT_LOOKUP version of lsp_to_curve

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]; ...

Hello, all. 1) ACE does not work for me I am in a voip project using Speex, failed to have hte Speex ACE work. here is how I initialize it: /** * Configurations : * #define BITS_PER_SAMPLE (16) * #define SAMPLE_RATE (8000) * #define CHANNEL_NB (1) * #define DURATION (20) * SPEEX_MODEID_NB */ _eco_state = speex_echo_state_init(_encframe_size, 10*_encframe_size); speex_echo_ctl(_eco_state,

Jack, I got the asm we were working last night committed ont he beta 3 branch. It's in use in both vorbisfile:ov_read() and the lsp lookup (when using float lookups) I'd like to have a patch of the other things you did in the past day or so, even if you don't want to commit yet.

Hello I'm working on a fix-point decoder for AOS/Bluebottle - the proprietary OS of ETH Zurich. I've some problems with Floor0-curve-computation: I don't know what the little omega [cos(w)] stands for, line 3 of the official Vorbis documentation. Does anybody knows what this value means? I've tried to get the answer from the jOrbis and Tremor, but both seem to do - among

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

All, We are using a SIP provider that is expecting 0-15 response for fmtp. Our CVS Head asterisk server is sending 0-16, I looked up an rfc and it stated: RTP Payloads for Telephone Signal Events RFC 2833 Henning Schulzrinne, Scott Petrack. May 2000 Implementation notes: * Implementations can support events 0 through 15 (DTMF) by simply ignoring the packets, but MUST

I just finished the merge of branch_jackoggsvorbis into branch_postbeta2 Vorbis is now split into two libs, libogg, and libvorbis in this branch. the follow modules are a result: ogg - basic framing library, all ogg code and docs, etc vorbis - the vorbis codec, depends on ogg vorbis-plugins - all the audio plugins for ogg vorbis, depends on ogg and vorbis ao - libao a cross platform audio

Hello everyone, Since my question is quite theorical, I am not sure whether it is the right place to ask, but anyway... I am working on time series and I looked at some way to fit my data through arima models. Since these data are updated frequently, I was looking at a way to update the model "on line" (to get a kind of recursive estimation) So the next step was to express the arima

Hello, I've had no luck finding an R package that has the ability to estimate a Tobit model allowing for heteroskedasticity (multiplicative, for example). Am I missing something in survReg? Is there another package that I'm unaware of? Is there an add-on package that will test for heteroskedasticity? Thanks for your help. Cheers, Alan Spearot -- Alan Spearot Department of Economics
