speex_nb_mode declaration problem
Hello all, I am using the speex APIs in a gnuradio block. I used the similar code as in the sampleenc.c/sampledec.c which works perfectly fine. My compilation does not give any error, but when I run the python test, it complains that speex_nb_mode is undefined. I tried to declare it explicitly then it as const SpeexMode *mode = NULL , then i get an error that i cannot initialize the const

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

Packet Loss question
Hello all, I know that SPEEX has a mechanism to handle packet loss. I see there is some handling for packet loss implemented in speexdec. I want to know, if in my own application should i also implement such packet loss handling or is it taken care of within the decoder? I want to test my SPEEX application for GNU Radio for some packet loss,if i just simulate a packet loss mechanism, will it work

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!

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

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

Windows Mobile 5.0 SDK - SPEEX
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

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

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...

Using speex (newbie)
Thank you for the answer but i've already read manual and examples and i'm doing same thing of your code, so, maybe you can give me a hint about the problem i have, that it is for sure in my code. A question: is it possible that i hear a "tick" because between two frame i call speex_bits_reset? (for this reason if i encode more than one frame together there is no

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

Problems with stereo data
Hi all, I have a problem when I am encoding (or decoding) stereo audio. With mono data, things are fine and everything works without any problems. When I try to decode stereo data, all I get is a static sound - similar to that of a radio not tuned to any specific station. I wonder what might be wrong? Below is the code, first, of the encoder and next that of the decoder. Any information or

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

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

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

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

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

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
