okay that questioned is answered, thank you. I am interested in using speex in a VOIP application. do i need to put it in into the ogg contianer format in order to encode/decode and send it? or will it work "as is"? if the latter then: "the packet is larger than the allocated buffer" message: whats your recomendaton for fixing that? i was thinking simply getting the size of

For a streaming application like VOIP, you collect 20 ms of samples, feed this through the encoder, stick it in an RTP packet, and send if over the network. On the receive side you feed packets through a jitter buffer to the decoder, and then copy the output audio to your output device. Speex runs efficiently on most compilers, so the real-time requirement is not a big deal, as long as you

Hi, For the openSpeak project we use PortAudio V19 & speex. So if you want some code examples, you can look an pick in our SVN (its GPL). ATM we are having some problems with PortAudio v19 (it might still be buggy somehow, it seems not to support the 32-kHz sampling rate used by speex ultra-wide-band mode) so if you want something stable you'd better use v18. And of course, if you

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

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, 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

Re: [speex-dev] Error in compiling Speexdec code (Speex-1.1.5 code)onWindows usingVC++6.0Actually one thing i should point out if you do decide to go this route.... currently my demuxer builds a seek table, which could potentially be a bit of a memory hog on a small device... though when i get around to adding the networking code, i will have to use my bisection seek code, so the use of the seek

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

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

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

Hi All, I am quite new to voice encoding and to Speex library. I have some programming questions that I am not able to answer even after having read the documentation (from the start to the end an from the end to the start) and by reading the sample code (provided in the documentation) and the speexdec.c and speexenc.c programs. I am currently working on an interface between Java code and

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

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

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

The following patch (based off of the current CVS tree) is necessary to compile Speex on IRIX (or any other system that doesn't include getopt_long in the system libraries). I would suggest further that src/getopt_win.h be renamed to getopt_long.h since it's not just Windows that lacks getopt_long. Michael Index: configure.in

HI, I am also working on VOIP application. Now the speexenc.exe is used to encode a wav/raw file. However, in real time voice communication, the voice keep recording from the microphone and how can we employ speex to compress the voice and send over the 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...

Hi I'm implementing (for the open source) a little voip app. (intended to be used by another remote-assistance tool, but usable 'per se'). I'm currently using GSM encoder, but would like to use Speex, too. I must make some mistake using the lib, because when using Speex I have some problems with speech quality (no matter how I tune Speex params.). I'm asking if it's
