Hello! I should have asked this earlier, but... :) We're returning to voice processing in our app now, in which we're trying to achieve n-way full duplex voice in a 3d environment. Since Speex is a single voice stream CODEC, we've been looking at having each client upload its stream to the servers, which multiplex several spatially nearby active channels back down to the

Bonjour, D?apr?s votre question ? Jean_Marc : ? Je m'int?resse ? la source 1.0.5, et je ne vois pas une _spx_lpc (). Il ya une _spx_autocorr (), qui est en lpc.c et est appel? ? proximit? du d?part de la Codeur fonction dans nb_celp.c. L'encodeur semble appeler la autocorr () la fonction, puis appelle wld () pour faire quelque chose qui s'appelle Levinson-Durbin.

Dear Stefan, In the paper "Improved Forward-Adaptive Prediction for MPEG-4 Audio Lossless Coding", a non-linear compander is applied to the parcor coefficients prior to quantization. This compander is designed in order to minimize quantization error, especially for magnitudes close to unity. If you determine the typical distribution of magnitudes of the LPC coefficients, you could

Hi Jean-Marc I'm looking at the 1.0.5 source, and I'm not seeing an _spx_lpc(). There's an _spx_autocorr(), which is in lpc.c and is called near the start of the encoder function in nb_celp.c. The encoder seems to call the autocorr() function, then calls wld() to do something called Levinson-Durbin. Am I right in thinking that after the call to wld(), the st->lpc[] array

Hi, I plan to use AEC for a live performance, storytelling for very young children (and their parents!) in a mongolian yourte . Actually the storyteller can make vocal loops, there is an omnidirectional microphone in the center of the yourte, 5 loudspeakers in a circle along the yourte's wall and Pure Data in a linux box. And now she wants to make vocal loops over music and loops over

Hi, can someone help me understand and experiment with Speex in a better way than my knowledge. I want to change the LPC filter order of the Speex algorithm. I think I need to change the LPC order( or lpcSize) in modes.c file. but to make it work I need to modify the codebook also, can someone tell me how to go about changing the codebook entries to support the changed order of prediction.

Hi, We are pleased to announce the call for presentations for this years Confidential Computing MC at the Linux Plumbers Conference. In this microconference we want to discuss ongoing developments around Linux support for memory encryption and support for confidential computing in general. Topics of interest include: * Support for unaccepted memory * Attestation workflows * Confidential

I have noticed lpc slowdown both in encoding and decoding, not related to new config.h stuff. It seems there is wrong choosing of fastest possible version of lpc function.

I am using the code below to extract census tract information. save.tract$state, save.tract$county and save.tract$tract are returned as factors. In the last three statements, I need to save the actual value of the factor, but, instead, the code is yielding the position of the factor. How do I instead return the value of the factor? By way of example, for Lon=-82.49574 and Lat=29.71495, the code

Hi I am using R for logistic regression and finding it very useful. However, I wondered if anyone could point me to any course or notes on this subject using R. All help most welcome. Stephen -- Internal Virus Database is out-of-date. Checked by AVG Anti-Virus. [[alternative HTML version deleted]]

Hi I am trying to use this function. Can anyone show me how I would input the following example? Chi-Squared = (40-30)^2 + (20-30)^2 + (30-30)^2 30 30 30 = 3.333 + 3.333 + 0 = 6.666 (p value = 0.036) I want to be able to use different denominators so can you show me how I can do it to accommodate these rather than assuming they are all the

Hi everyone! It's my first time posting to this list, and I've got a fairly technical question. I'm interested in doing phoneme extraction, and one of the first steps in the algorithm I'm planning to use is to get the LPC coefficients for an input frame. Since Speex is CELP-based, the coefficients must be generated in there somewhere. I've tried digging around in the source

Hello! I just noticed how the LPC prediction is quantized by browsing the source code of the java port jFlac: : int sum = 0; for (int j = 0; j < order; j++) sum += qlpCoeff[j] * data[startAt+i-j-1]; data[startAt + i] = residual[i] + (sum >> lpQuantization); : I checked the C version (libFLAC) and it matches. However, it was a surprise because this way of quantizing the

Hi I can get all my features by doing this: > logistic.model = glm(similarity ~ ., family=binomial, data = cData[3001:3800,]) I can get the product of all my features by this: logistic.model = glm(similarity ~ . ^ 2, family=binomial, data = cData[3001:3800,]) I don't seem to be able to get polys by doing this: logistic.model = glm(similarity ~ poly(.,2), family=binomial, data

Hello, I just tried to compile libFLAC (using Borland C++ Builder 6 on Windows). The compilers yells at me on line 233 of libFLAC/lpc.c *(residual++) = *(data++) - (sum >> lp_quantization); --> data is const and cannot be modified Funny thing is, if data is declared: const FLAC__int32 *data instead of const FLAC__int32 data[] everything is ok. Is this a bug in my compiler, or
