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

Hello Carl, Can you send me libspeex compilated in eVC. And can you describe where and how set the FIXED_POINT flag in eVC. Thanks you. Regards.

Hi I'm trying to unzip the source code for the Speex Encoder, but I'm not having much success. I've tried using WinZip (unregistered version 8.0) and PowerArchive (version 6.1). Neither of them open the files "speex-1.0rc2.tar.gz" or "refman.tar.gz". What am I doing wrong? Many thanks Jim --- >8 ---- List archives: http://www.xiph.org/archives/ Ogg

Thanks for your reply Jean-Marc! this was what I had before. But I decided to restructure it since the thread that plays the sound is a callback from the sound hardware, more or less an interrupt handler. For me it seems more reasonable to waste some memory for to save the decompressed Packet. While I write this I begin to think that it is possible I decompress Packets that are never used

I noted Duncan's comment that an answer had been provided, and went to the archives to find his earlier comment, which I am fairly sure I saw a day or two ago. However, neither May nor June archives show Duncan in the thread except for the msg below (edited for space). Possibly tech failures are causing misunderstandings.

Well, I've been slamming my head against this all night, so it's time to ask for help... Having gotten together a reasonably decent port of what I thought was the whole API to the Ogg Way, complete with Ogg mem management and bitpacking, I started digging deeper in the code... only to find that it looks like I only have a middle stream handler. The encode and decode code both assume that

I am studying the speex 1.0.5 C source code ,but i feel it is hard to understand the code ,especially the ltp.c and filters.c file. may you tell me the detail algorithm or the more detail notation of the source code of this two file.including below functions void open_loop_nbest_pitch(float *sw, int start, int end, int len, int *pitch, float *gain, int N, char *stack); float

Hi John, I noticed the values after decode is very much different from the values of the original PCM samples. For cases when the PCM sample values are constant (because no one is speaking), the decoded values fluctuate too. These fluatuations are causing the background noise. Is my observation expected?

Hi, I am using the speex 1.0.4 library from Windows. I have posted my problem before but didn't get a solution. I am doing an VOIP project in which i am recording sound and streaming it to the peer. I wanted to encode and decode wav files that brought me to this site. I am recording sound in the following format:- m_WaveFormatEx.wFormatTag = WAVE_FORMAT_PCM;

I'm working in .NET and have found that there is, unfortunately, no simple way to access unmanaged, object-oriented APIs from C#/VB.NET. Ultimately I have decided to adapt speexenx and speexdec into a simple, functional API with two functions: one for encoding an array of bytes, and one for decoding it. Does anyone know if the source code for speexenc and speecdec is available, or are they

Hi, We would like to announce the first release of the Speex project. Speex (http://speex.sourceforge.net) is an open-source (LGPL), patent-free compression format allowing an alternative to expensive proprietary codecs. Unlike Ogg Vorbis which compresses general audio, Speex is designed especially for speech. For that reason, Speex is meant to be a complement to Vorbis. Since it is specialized

Hi, I am using the JitterBuffer. Since there is not so much documentation I think I dont use it in a correct way. All the packets are recieved (I control the sequence numbers) but the JitterBuffer often tells me he has no packet. I am using it in the following way: I am not sure if I use the ticks correctly but I think it can be set to 20(msec). It is set as a Member in my class and i

hello dear developers, i'm a student of computer science at the technical university of berlin. i'm on my exam and i have to implement an "perfect" hifi-internet-telephone :-) ... at this point i thought of vorbis and the ogg-vorbis codec to integrate this codec in my tool ... the questions i have are: is the source code lying on a free server to download it? is there a

Hi I apologise if the following message is inappropriate for this list. However, I feel this is the only place where I can get some help with my problem.

Hi Chris, Thanks a lot for your help. I've been able to resolve all the errors except one. I don't have ogg.h header file, so when I try to build Speexdec.exe, I get an error d:\speex\speex-1.1.5\src\speexdec.c(44) : fatal error C1083: Cannot open include file: 'ogg/ogg.h': No such file or directory I don't have this file, but as I wrote in my previous mail, an ogg_static

Thanks a lot for your replies. Where can I get Ogg static libraries header, and Ogg header files. Any place where I can download. Basically I need to create a Speex library for Pocket PC 2003, that can be used from within my .NET Compact Framework application. For this I need to create a DLL file, which essentially is my Speex decoder. For this I simply need to make use of Speexdec, since this

As you know, Winamp relies on the file extension to know what input plugin to utilize for the audio decoding. The input plugin for .ogg files (in_vorbis.dll) needs to understand the other ogg container formats but it doesn't as it is a vorbis only decoder. So the only solution is for Ogg Speex to have a different extension so this can be appended to the mountpoint, and an input plugin

Thanks a lot Zen. Basically I'm trying to create a Speex decoder for Pocket PC. Actually I've already implemented an application for (talking phrasebook) Pocket PC using .NET CF. Now in that app I'm using XAudio MP3 decoder to play MP3 files from within my application. My doesn't have a player GUI, I'm just using the MP3 decoder programmatically from within my app. Now since

Hi, I've downloaded the Speex-1.1.5 code and am trying to compile the Speexdec code using Microsoft VC++ 6.0 IDE. When I try to open the speexdec.dsw workspace, I get a dialog asking to locate the ogg_static file. I simply cancel that message, and then the project is opened in the VC++ 6.0 IDE. Now, when I simply try to compile the program, I receive this 5 error messages. error1.
