Re: Sending speex over a network
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...

Sending speex over a network
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

Encode and decode using speex
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

Error Executing sampledec in VC++
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

Error Executing sampledec in VC++
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

file couldn't play after Speex encode and decode
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!

Noise problem while encoding and decoding
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

Decode win32 encoded files on TI C5x???
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

Decode win32 encoded files on TI C5x???

There is no such a thing as a "raw Speex format". Also, sampleenc.c and sampledec.c are good for learning how to use the API, but the compressed format shouldn't be used in

HELP?
Platform Intel Linux/Fedora Core 2 ALSA Soundblaster 128 PCI I am capturing U8 (unsigned 8 bit mono) audio from the sound blaster and attempting to compress it with speex. I have built and installed speex on the computer and can compile and link with no problems. I have the sample programs (sampleenc.c and sampledec.c) which I am following. The only difference is my raw data is in a char array

How to use speex?
Hi, I am a newcomer to speex. When I use the sampleenc/sampledec programme to have a try of speex, the encoded and decoded file can not be played in foobar. But if I use the speexenc.exe/speexdec.exe in the Windows binary tools, the encoded file can be played well. Did I misuse something and can anyone provide a simple example for how to use speex to build my own programme? Any

Raw files or Wav Files
Hello All, I have recently started working on SPEEX and thanks to the nice tutorial and examples, i was able to encode/decode files as per the command line programs speexenc.c and speexdec.c I tried the sampleenc/sampledec but, i know its only for the raw data. My question is what kind of raw data should be used to test them? Also, is it possible for me to use speex without any of the headers but

decoded sample is completely differen from original one
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

Speex Windows from 1.1.6 source
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

Raw Speex?
Hi, I want to take a .wav and generate a bytestream that I can feed direct to speex_decode(). The speexenc program appears to produce it wrapped up in an ogg stream, and it doesn't have any sort of "raw" mode. I've tried hacking on it to remove the ogg parts, but I must have got it wrong, as my decode dies after decoding 160 bytes (which I believe is one frame) with an

Integrating speex with VideoNet application: Constantbackground noise
Hi Jean-Marc, Thanks. I've got the code for sampleenc and sampledec. But I didn't know how to verify whether the decoded file is correct. So I tried to analyse the decoded output and compile with my input. Test case: PCM samples, 8 bit, 8000 samples per sec. When I pulled all my input to 0s, after encode and decode, the output fluctuates around -0.12 to 0.2 (in float), so when finally

Speex encoding/decoding producing garbled audio
I'm getting garbled playback with decoded fragments and I'm hoping someone here can point me in the right direction to correcting the problem. Essentially I'm capturing audio from the microphone. I stream it over the net, but for testing purposes with this API I'm just grabbing the whole chunk and encoding / decoding it right away and then updating the sound buffer for
