The example in the documentation demonstrates using speex_bits_reset before encoding and decoding each frame. " speex_bits_reset(&bits); speex_encode(enc_state, input_frame, &bits); nbBytes = speex_bits_write(&bits, byte_ptr, MAX_NB_BYTES); " What happens if this is not done? I think I'm missing the point of having a SpeexBits object.

Hi All, i need your help in determining the problem in the following sample code (taken from speex manual) for fixed point encoding. i tested encoding a 160 sample frame and then decoding it back But The problem is that the decoded frame is totally different from the original frame(see output below).What is the possible reason for this?.thanks for any help #include<stdio.h>

Hi, Speex-dev I've been able to get Speex to compile on SM400M(MIPSII) with problems. ------ Rebuild All started: Project: speexenc, Configuration: Debug SM400M (MIPSII) ------ Deleting intermediate and output files for project 'speexenc', configuration 'Debug|SM400M (MIPSII)' Compiling... getopt.c getopt1.c skeleton.c speexenc.c .\speexenc.c(501) : warning

The API reference says it is "+-2^16 range." Which is right? I've yet to successfully encode or decode anything.

Hello, I'm trying to use the speexlib but I just can't do it. I've made just like the example (on the site) says. Some times I get SIGFAULT. Also, I'm reading the input_frames from /dev/dsp (directly). What is missing here? speex_bits_init(&bits); enc_state = speex_encoder_init(&speex_nb_mode); speex_encoder_ctl(enc_state, SPEEX_GET_FRAME_SIZE, &frame_size);

Thanks for the reply, Conrad. What is not clear for me (and I didn't found it on the

Hello, i want to use speex out of visual basic. So i have written a few wrapper functions in VC++ (v6) wich i can call from VB (v6). But i have problems with the encode and decode functions. Encode wrapper Function: I want to copy the value of an single array in VB to a float array in C which can be encoded. And the output of the encoder have to be unsigned char because in VB its an byte

>From the sample encoder/ decoder demo in the documentation it seems that I only have to call speex_bits_reset before encoding a new frame. Is this still the case if I reuse the SpeexBits to both encode and decode different streams?

Hi Randy, thanks for the reply. So, suppose I encode an audio buffer (8000 kHz, MONO, float) of 640 PCM frames. In output I have 4 speex frame of 20 byte

/input_frame/ is a /(float *)/ pointing to the beginning of a speech frame What is the range on the floats in the input_frame that speex_encode() needs? The library that I'm using to get the sound gives me floats that are between -1.0 and +1.0. I was assuming that this is also the case for speex, but I don't see it documented. I'm thinking now that maybe this is not the case for

Hi SAITAMA Taro, I have been using speex-1.2beta1 dll in our voice application written with C#. In order to use Speex correctly firstly I advice to you examination speexenc and speexdec projects. I have used unsafe code and fixed statements in C#. I have added following method to library and I used that instead of speex_encoder_init simply. void *speex_encoder_init_new(int modeID) { const

-------Original Message------- From: Eid Date: 10/09/05 14:07:44 To: speex-dev@xiph.org Subject: problem in encoder/decoder hi all, I'm developing an app to broadcast voice over web. i tried to use speex and download ver 1.04 documentation and use it to develop encoding and decoding but after decoding voice is damaged i attach my encode/decode function. BOOL

Alright noted, I changed me code so that the state is created in the constructor and destroyed in the destructor of the object. However I'm still getting the same issue although I'm sure that would have bit me sooner or later. The new code is as follows. virtual Enigma::u8* Encode(Enigma::u8* inputBuffer,size_t inputSize, size_t& outputSize) { short *in=(short*)inputBuffer;

It would be nice to have the following function added to the speex bits... void speex_bits_read_from_buffer( SpeexBits * const bits, void * const buff, const int buf_size) { bits->bytes = (char*)buff; bits->buf_size = buf_size; bits->nbBits = buf_size << 3; bits->bytePtr = 0; bits->bitPtr = 0; bits->owner = 0;

Hello, im using speex library on my vo ip project, but some times, after it works ok, it begins to play noises (like voice hits) decoding the packets of one source (the others sound ok). I finally found that reseting SpeexBits and decoder state it solves. If i cant avoid this problem, i wish to solve when it occours, but ?how to detect this? Please, if anyone has experiment this issue i

You're doing something wrong. Read the documentation and check speechenc/dec just one more time. If that wouldn't help I'd suggest posting samples of your source code and describe what platform/compiler/os you're using. //JT -----Ursprungligt meddelande----- Fr?n: speex-dev-bounces@xiph.org [mailto:speex-dev-bounces@xiph.org] F?r jesus Skickat: den 22 januari 2007 19:43 Till:

Hi Marian, I took a brief look at RFC 5574 and as far as I understand, you can simply do it like this: SpeexBits b; speex_encode(state, some320bytePCM1, &b); speex_encode(state, some320bytePCM2, &b); After that, get the encoded data with speex_bits_write and put it in your packet.
