Thanks, it makes more sense to me now. Does speex_bit_read_from also append in that manner? Jean-Marc Valin wrote: > speex_bits_reset is before encoding, not decoding.

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

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);

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

/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

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?

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;

Hi, I'm trying to use Speex for real time encoding in an iPhone project but I'm having latency problems. I appreciate any tips you may provide for speeding things up. The recording callback is providing 1024 samples (mono, frequency: 44100 Hz, of type short) every 23 ms (1024.0 / 44100.0). I'm saving the samples in a buffer and use them in the encoding thread (set for mode: wide

I'm completely new to speex and I'm having issues adding it to my application. I can pass raw PCM and that works fine so I know my transmission code is fine however when I try to encode/decode using speex I get noise almost like a whining/buzzing sound. I'm sure it's and issue in my code but I'm not sure where to start looking other then my gut tells me I'm not sizing or

Hi all, I have just started playing with speex, and come up with the following code, which just encode a frame of 160 shorts, and the decode it. For some reason the decoded sample is completely different than the original one. is my code wrong? If so what? Or is it a reasonable which depends of values that weren't correctly set? Thanks, Andre #include <stdio.h> #include

I'm only doing one frame using speex_encode_int greatly simplifies my code I'm not sure why the sample I was working off of was converting the shorts to floats then calling the other encode/decode methods. Based off of your suggestions I tried the following but I get the same result. virtual Enigma::u8* Encode(Enigma::u8* inputBuffer,size_t inputSize, size_t& outputSize) {

Hi i'm developing a sort of VoIP application for my ipaq using speex... I'm still at beginning and i have many problems encoding and decoding my wav files....output is only noise! Why? I'm using Libspeex 1.1.3, Embedded VisualC++ 3.0, Ipaq 3850(206 MHz Intel® Strong ARM 32-bit RISC Processor) PocketPC 2002 (Windows CE 3.0). Libspeex is complied with the definition of

Hi, Sorry! Marc Gimpel. I wrote it in a false thread before. It was my first time. :-) I have to write a small programm which should be able to record speeches and in addition synchronize the recorded speeches with measuring data. My idea is to record the speech in the normal way with speex and without ogg. If a sync message was received, i write a custom in-band messages using mode 13

Hi Steve, thanks for the advice. I placed the appropriate functions outside the while statement but I still get this error at the while loop: First-chance exception at 0x004010fa in SPXDEC.exe: 0xC0000005: Access violation reading location 0x0000000c. Unhandled exception at 0x004010fa in SPXDEC.exe: 0xC0000005: Access violation reading location 0x0000000c. It looks like the same error. I've

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

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.
