similar to: speex_encode segfault

Hi, i'm following encoder example in the manual.pdf of speex documentation. Here's my portion of code: int SPEEX_EncodePCM(struct _IDA_ClientSocket *IDA,char *buffer,unsigned char *PCM,int num_samples) { int ret,c,d=0,nbBytes,ttBytes=0; float PCM_F[160]; char cBits[200]; #ifndef DISABLESPEEX speex_bits_reset(&IDA->speex_bits); for(c=0;c<num_samples;c++) {

Hi all, i've to encode voice from a voicemodem. I choose speex 1.0.5 for its quality in voice encoding. I've tried to implement an encoder but unsuccesfully. Here's my code: /* ============ SPEEX stream ENCODER ============================================ */ int SPEEX_EncodePCM(struct _IDA_ClientSocket *IDA,char *buffer,unsigned char *PCM,int num_samples) { /* buffer point to the

Hi, what is the good way to encode / decode multiple frames in packet ? I read that I must do multiple call to encode and thats it. But when I'm trying to decode,, it doesn't work. Maybe, the problem is my decode function. Here is my encode function void ms_speex_enc_process(MSSpeexEnc *obj) { .... Do I need to increase gran value to 640 or read / encode (2 times)

Hi, Guys I am starting looking the source code of Speex. Maybe a little silly, but I can not find the implementation of the function speex_encode(). Only something like below void speex_encode(void *state, float *in, SpeexBits *bits) { (*((SpeexMode**)state))->enc(state, in, bits); } Does that mean some of the detail implementation is embedded in lib without source code? I am new in

Speex 1.0.3 uses floats, but the unstable version 1.1.x uses short.

I always think short is better over float, because most of the time we don't get float form data, from, e.g microphone / wav files <p>-----Original Message----- From: owner-speex-dev@xiph.org [mailto:owner-speex-dev@xiph.org] On Behalf Of Conrad Parker Sent: Monday, April 26, 2004 12:58 AM To: speex-dev@xiph.org Subject: Re: [speex-dev] speex_encode / speex_encode_int ... already sorry

Hardware generally uses integer samples, but a number of newer software systems use float. On modern host cpus it's just as fast and you don't

openh323 speexcodec.cxx has: BOOL SpeexCodec::EncodeFrame(BYTE * buffer, unsigned & length) { // convert PCM to float float floatData[SAMPLES_PER_FRAME]; PINDEX i; for (i = 0; i < SAMPLES_PER_FRAME; i++) floatData[i] = sampleBuffer[i]; // encode PCM data in sampleBuffer to buffer speex_bits_reset(bits); speex_encode(coder_state, floatData, bits);

I'm confused about the format of the PCM/WAV data for speex_encode & speex_decode speex_encode(enc_state, input_frame, &bits); In the manual, it says "input_frame is a (float *) pointing to the beginning of a speech frame" (for encode) But I've found that in speexenc.c and testenc.c, short* is used instead of float* So, isn't it signed 16 bit samples(if

Hi, i know this question has already been asked, i've checked mailing list logs but ... I didn't figure out the solution for my question. I want to use basic functionnality of speex, only VAD, no pre/post filter, even no VBR. But i *really* want to use less mem/cpu i can. So in which format should i pass data to speex_encode(_int) , float or short ? I quickly looked at the source code

I just remembered an anomalous result that I stumbled upon whilst tweaking the command-line options to llvm-gcc. Specifically, the -msse3 flag does a great job improving the performance of floating point intensive code on the SciMark2 benchmark but it also degrades the performance of the int-intensive Monte Carlo part of the test: $ llvm-gcc -Wall -lm -O3 *.c -o scimark2 $ ./scimark2 Using

Dear R Users, Any insights into why the following occurs would be helpful.... Firstly: #Evaluating proportions p<-as.list(rep(0,times=length(n))) #creating object of appropriate size. for(j in 1:length(n)){ for(k in 1:length(n[[j]])){ p[[j]][[k]]<- (s[[j]][[k]]/n[[j]][k])}} # 31 x k x num_samples(dim) where k varies The list object s[[j]][[k]] has 3 levels, j, k, and i. j represents the

I'm using resample.c from speex in my project, and was testing it by processing the same waveform twice, with a reset() call in the middle, as follows: short *input_data = read_waveform_as_linear(infileName, &rate, &num_samples, &num_channels); SpeexResamplerState *state = speex_resampler_init_frac(num_channels, in_rate, out_rate, in_rate, out_rate, quality, &error);

The replay gain code has dos line endings in CVS, which causes problems for the Sun compiler, among others. Attached is a patch for the lazy, but it's probably easier to fix locally and commit. -r

Estimados usurios-R: Tengo una lista de alumnos. Hay alguna forma de sacar una tabla de frecuencias por la asistencia a clases mensual. Es decir cuantos días concurrió cada alumno en el mes. Supongamos que la lista está conformada por ocho alumnos, el curso duró 4 días y quiero saber cuantos días concurrió cada uno al curso poniendolo en la columna mes. Quisiera obtener un cuadro así: Alumnos
