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

Hello I've looked into SPEEX SDK and source codes provided on site www.speex.org , and I'm trying to include in my Visual Studio 2005 - Visual C++ SmartDevice WM 5.0 the facilities provided by SPEEX (both encoding/decoding).I've downloaded the header files (i.e. Speex.h Speex_bits.h etc) and also the libspeex.lib.After creating my encoding/decoding functions following the

Hi, I am new to speex and I am trying to use the sample program given in the speex document. I have made some modification to that sample, so that input can be read from a file and the output can be re-directed to the file. I tried to encode an audio file using the sampleenc and decode the same by sampledec.c I am able to do it successfully, but when i try to play the output file from the

Hi All, I am using Speex for encoding/decoding the audio stream for my streaming application. I have used almost the same code In the sampleenc.c and sampledec.c, except that I have used The buffers from the mic as input for encoder and encoded audio As input for decoder, instead of files input. My Problem is the audio played on the receiving side after decoding Is only a "hush" or it

I have problem with coding and decoding. I record voice from mic coding and write to file. And when I read from file and put it on sound card it's terrible sound. Have sameone can help me? #include <speex.h> #include <stdio.h> #include <fcntl.h> #include <sys/ioctl.h> #include <sys/soundcard.h> /*The frame size in hardcoded for this sample code but it

Hi all. I am a student writing a voip program on ppc for a project for school. Before I explain my issue, let me apoligize for being extremely newbie :( Here's the situation: I am using the ARMV4 release build from the speex website. Right now I am simply trying to make an encode function using speex that will take an unsigned char* of raw wav data (8000 samples, 8 bits / sample, mono)

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

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.

hey guys, I just compiled an application similar to sampledec.c (for speex 1.1.10) and it was fine but when I executed it, the app exited without doing anything. I'm using MS VC 6.0 and this was all I got - First-chance exception in sampledec.exe : 0xC0000005: Access Violation. Has anyone encountered this / does anyone know how to deal with it? by the way, sampleenc executed perfectly... When

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 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

Dear sir, I've a problem that the .wav file couldn't play after calling "sampleenc male.wav|sampledec male_speex_15.wav".I found that the new file male_speex_15.wav is smaller than the original file in size.I implemented the test on Linux system.The original file male.wav is 96044 bytes,while the new file male_speex_15.wav is 96000 bytes.I'm eager to know the reason.Thankyou!

Hi All, I am a Speex novice but trying to use Speex in my Doctoral thesis. I installed Speex, was able to encode and decode files. Right now, I want to write my own cpp program that handle Speex-files. I tried to compile and run the two sample programs that come with the documentation (after having insalled the speex-devel-1.0.5-1.i386.rpm). However, when I compile. gcc sampleenc.cc Here is

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, In sampleenc.c and sampledec.c, if I change the FRAME_SIZE to any other value, I get very garbled speech. Can anyone tell me if I need to set something else if I would like to change the frame size ? Thanks -------------- next part -------------- An HTML attachment was scrubbed...

Hi, everyone! I'm a newbie of speex develog. I tried to encode and decode with the sample program in the speex manual. I compile those program with gcc sampleenc.c -o enc -lspeex gcc sampledec.c -o dec -lspeex I run these two program in this way and then speak loudly: ./enc /dev/dsp ? ./dec /dev/dsp I thought I would hear my voice. However, what i heard was a lot of noise. I

Hi All, I would like to communicate speech over a network compressed using speex. However, I do not want to communicate a whole Ogg-formatted file. I am interested in only the speech frames. I invoked: speexenc input-file-name - > raw-speech This, I am thinking gives the speech frames only. To play this back at the receiving end, do I need to format it into Ogg formatted file before I can

I have successfully DECODED speex on TI C5509: #define TESTENC_BYTES_PER_FRAME 20 /* 8kbps */ #define TESTENC_QUALITY 4 /* 8kbps */ I am trying to generate the files I need with speexenc.exe: speexenc -n --quality 4 -V male.wav male.spx But I can't decode the files on C5x. Yes, I have seen that speexenc.exe adds Ogg header and
