I am trying to compile speexclient.c. I downloaded all the files to ~/speex- 1.2beta1/include When I call ./compile.sh I get the following errors, speexclient.c: In function 'main': speexclient.c:164: error: 'SPEEX_PREPROCESS_SET_ECHO_STATE' undeclared (first use in this function) speexclient.c:164: error: (Each u...

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

Hi all: How to use jitter.c, I see this file is not include in the lib. Sorry for this newbie Q.

Hello? My name is Hyeonwoo Oh. I?m developing video conference software using speex library. Can you give me some sample codes for acoustic echo canceller and noise reduction? I tried noise reduction API, but failed. Normal encode/decode API is working well. Thank you very much for your good job. I?m very pleased with speex. Best regards, Hyeonwoo Oh

...ently on most compilers, so the real-time requirement is not a big deal, as long as you know how to do this with your operating system (if you have one). You do not need Ogg containers for something like this, just search the archives for RTP references and you will find much more. Look at the SpeexClient application provided in the source tree, and at the testenc examples in the libspeex directory. The Speex part of things is pretty easy (thanks to Jean-Marc). It is the audio interface for your specific platform and the call setup protocals (e.g. SIP) where the real work is. If you identify...

Hello, In a way similar to speexclient voip example, I want to have a voip application where 3 or more users can interact. This creates the following problems "1. How to playback 2 or more audio streams such that they appear overlayed (parallel)". The audio streams are speex encoded. I have few approaches in mind. 1. Create...

It's in svn at http://svn.xiph.org/trunk/speex/speexclient/

Hi all, as in subject, speex_preprocess inject noise in my data. Someone can help ? Here's the way that i'm using: #define NN 160 /* 20msec di audio */ #define AUDIO_SAMPLERATE 8000 spx_int16_t TEMP_Buffer[NN]; speex_pp_state = speex_preprocess_state_init(NN,AUDIO_SAMPLERATE); c = denoise; speex_preprocess_ctl(speex_pp_state, SPEEX_PREPROCESS_SET_DENOISE,&c); c = agc;

Hi all, i've been having problems for the past little while with finding a app library for my voip application. then looking at speexclient i noticed there are timestamps and sequence numbers included in the implementation. my question is: should i get a third party RTP lib for my application or simply emulate the speex client in its RTP like properties. wouldn't it be easier and require less overhead and produce less latency i...

Hello, is there any sample code that uses libspeex? I wrote an app that uses it according to the manual, but the encoding does not sound good enough. I haven't figured out if it's a bug or a configuration. Is there any simple code that encodes properly? yx -------------- next part -------------- An HTML attachment was scrubbed... URL:

Hi, I'd like to report a bug in speexclient/speex_jitter_buffer.c. In the function speex_jitter_get(), after the line: packet.data = data; add the line packet.len = 2048; If this variable is uninitialized, then in jitter_buffer_get() (in jitter.c), the predicate "jitter->packets[i].len > packet->len" is undet...

Thanks for your quick response. Do you know how many playback frames that would be considered "ok" to buffer up in this scenario? I've tested the speexclient application and got similar results. There isn't any option to the playback/capture-mechanism for adjusting the buffer size? It feels like doing my own buffering would simply be a copy paste of your buffering but with a larger buffer size. I am bit confused here :-) Regards, Peter Jean-Marc V...

Hi, Indeed I too have troubles implementing echo removal, I like ask kindly to Jean-Marc (or any other) if him can put a source code demo to show us how to use effectively echo removal API and parameters in real case scenario.

thanks for the reply Jim. I'm actually well aware of the packaging, setup and teardown of sessions,and have the audio interface part figured out and implemented (Port Audio). The speexclient.c encapsulate audiocapture,encoding,sending and decoding. for my purposes now i've implemented my code more modular. first so i could understand each piece of the software involved and so i could come up with the best way i want to put it all together later. unless i'm missing something-an...
