similar to: ARM7 Speex decoder

Dear All I ported the speex decoder in LPC2000 ARM7 family. Because I fetched the .ogg file from and external MMC card, I can only red a limited memory block 1) Can I decode only a block of a speex file at time ? /*Create a new decoder state in narrowband mode*/ state = speex_decoder_init(&speex_nb_mode); /*Set the perceptual enhancement on*/ tmp=1;

Dear Ralph Thank you for your info. My file_read() function only get a specified number (nbBytes) of bytes from the .ogg file and store it in cbits, nothing else lb = file_read(&file, nbBytes, (void *)cbits); Unfortunately I have only 32K (first section) + 8 (second section) = 40 Kbyte of RAM to do all, including the file system management (I get the FS from the EFSL project). Speex

Hi , may I ask some question about the decode files? here is my decode.c but when the program run to speex_encoder_destroy(state); It shows that segmentation fault ,I feel comfused, could you tell thanks! #define MAX_FRAME_SIZE 320 int main() { FILE *fout; char *inFile; FILE *fin; short out[MAX_FRAME_SIZE]; char cbits[200]; int nbBytes; void *state; SpeexBits bits; //int tmp; int

Hi everyone, Our team is working on a realtime voice communication application. We are using openAL 1.1 to capture the samples and then encode them using speex. On the remote machine we decode the samples and play them using openAL again. Capture and play formats for the samples is AL_FORMAT_MONO16 and frequency is 22050. we are using wide band encoding/decoding. The encoding sample

Hi, Speex Fans, I collected the speex raw file from flash server and tried to decode it with samepldec.c ( I modified the code the file input) as below. speex rate=8khz, one framesize=10 bytes in the client, When I ran the decoding program, it kept displaying the error below and the file genertaed is corrupt too. Please help point out what is wrong. I also attach the raw speex file. Thanks,

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) {

I write a sample code like speex provide , as follows: SpeeXCodec::SpeeXCodec() { rate = 8000; speex_bits_init(&enbits); speex_bits_init(&debits); enc_state = speex_encoder_init(&speex_nb_mode); dec_state = speex_decoder_init(&speex_nb_mode); // set option for encoder speex_encoder_ctl(enc_state, SPEEX_GET_FRAME_SIZE, &frame_size); speex_encoder_ctl(enc_state,

You should really do a check to make sure nbBytes isn't larger than 200, otherwise you're going to read past the end of your char array. fread (&nbBytes, sizeof(int), 1, fo); _____ From: speex-dev-bounces@xiph.org [mailto:speex-dev-bounces@xiph.org] On Behalf Of Mo Win Sent: Monday, October 17, 2005 7:31 PM To: speex-dev@xiph.org Subject: Re: [Speex-dev] Error

The way I do this is to compute the number of frames (by dividing the size of my input by the number of bytes per frame and then calling speex_encode_int() that many times. Something like speex_bits_reset( &bits ); for( n = 0; n < num_frames; ++n ) { speex_encode_int( enc_state, (int16_t*)input_tail,

Hello, When I decode a recoded sound encoded by speex, it has too much noise. The noise is "slightly" reduced if I set the quality to 10. How do I get rid of this noise? The code is as follows. For encoding . state = speex_encoder_init ( &speex_nb_mode ); tmp = 7; speex_encoder_ctl ( state, SPEEX_SET_MODE, &tmp); // set quality tmp = 10; speex_encoder_ctl ( state,

I successfully encoded and decoded a wav file of PCM 16 , MONO and with sample rate 8000 in Android OS. The size of the original wav file and decoded file is near. But i am not able to play the decoded audio file, the mediaplayer says that the file has been corrupted.

Hi, My problem is at the second fread function, fread(&nbBytes, sizeof(int), 1, fin); //the first fread fread(cbits,1, nbBytes, fin);// the second fread. When I'm debugging always nbytes is greater than cbits. This give me a execution error. Thanks.

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;

Why my decoder doesn't want to return the data back to its original wav audio file that i can playback it correctly , is there something wrong in my code . Encoder : ======= #include "speex.h" #include <stdio.h> #include <iostream> #include <conio.h> using namespace std; /*The frame size in hardcoded for this sample code but it doesn't have to be*/

Hi all, Please a moment to look my source code, this is very similar to example of the documentation. I added FIXED_POINT flag. My source code compile and build but not decode correctly (the error may be in the while). I work with eVC 4.0 and pocket pc 2003. Someone know what is the error? Thanks. Rodrigo. #include "speex.h" #define FRAME_SIZE 160 void CPlayerDlg::OnButton3() {

hello everybody in this great mailing list , i have some difficulties to follow my code . i solved some problems thanks to Carine Liang , but i still have one problem and i think it is fatal one. when i encode the voice data in a wav file it is decoded without any errors it gives me 84 bytes wav file size for 139 kbytes wav audio data .Naturally i wanted to return my file back to its normal

You are writing to a test.wav file, but I don't see a RIFF header being written to this file. -----Original Message----- From: owner-speex-dev@xiph.org [mailto:owner-speex-dev@xiph.org]On Behalf Of Rodrigo Parra M Sent: Monday, 19 January 2004 11:20 p.m. To: speex-dev@xiph.org Subject: [speex-dev] decode in ppc 2003 <p>Hi all, Please a moment to look my source code, this is very similar

Note that FIXED_POINT is only related to compiling speex, not your application. Also, in 1.1.x, the output and output format for audio changed to 'short' (instead of float).

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
