>Also, 'portaudio' doesn't appear to produce a static library at all, so it doesn't appear to be possible to get a working splayer executable on Linux unless there is a 'hidden' way to get the portaudio distribution to build one. ("ldd: -lportaudio not found"). I believe splayer is...

Just a few weeks ago, I was thinking of writing a streaming source using libshout and portaudio. I was also considering LADSPA support, to do some minor post-processing before encoding. However, I'm currently developing on Mac OS X, and LADSPA's shared library plugin model has some issues here to be resolved. Another nice feature I have given a thought on is incorporating AudioCo...

The current Asterisk 13 and master git branches have a new feature that will be included in 13.8.0: The ability to compile and run Asterisk with a bundled version of pjproject. ?? Why would you want to do this? Several reasons: - Predictability: When built with the ?bundled pjproject, you're always certain of the version you're running against, no matter where it's

I am making a lightweight opus audio player. This is my portaudio callback function. But i hear a stammering song when i try to play a .opus song file. Can anybody say what is wrong or provide me link to any code which can play opus file written in c/c++(light). I tried to see some open source(vlc opus play) but was unable to follow. int MyCallback(const void* i...

Hello, I try to compile player_example.c from http://downloads.xiph.org/releases/theora/libtheora-1.1.1.zip in Visual Studio 2008 on Windows XP. I built and added to the project libogg-1.3.0, libtheora-1.1.1, libvorbis-1.3.2 (http://www.xiph.org/downloads/) and SDL-1.2.15 (http://www.libsdl.org/release/SDL-devel-1.2.15-VC.zip). When I compile player_example.c Visual Studio shows: fatal error

-----BEGIN PGP SIGNED MESSAGE----- Hash: SHA1 Hi all, I was wondering if anyone had any advice on an audio library that is better suited to be paired with Celt in terms of latency. I'm working on an application that I would like to have running on both windows/Linux systems. I started by using the OpenAL library but I have run into an issue when feeding OpenAL small mono sample sizes that

I am using 'portaudio' and 'speex' to implement a speech audio capture/playback. Preprocess works fine but not the echo canceller (associated with preprocessor). I have read 'testecho.c' but it didn't help me. What I am doing bad? This is my implementation: One thread to capture and playback, b...

...o_state, input_frame, echo_frame, output_frame); (in) echo_state => speex internal state. (in) input_frame => audio captured by mic. (in) echo_frame => the signal that was played in the speaker. (out) output_frame => the signal with echo removed. I'm under linux and using portaudio as sound API. My questions are: 1) How can I grab the signal that was just played (echo_frame parameter) ? 2) PortAudio can be used to achive this ? If so, how ? If not what is the best API for grabing the output samples ? 3) Is there any sample code available on using this function ? Thank...

It's a question of getting the compiler environment setup to do the port. Much of libshout and ices2 are ready but, certain things like live input are different from whats in windows. karl.

...york. I'm pretty involved in Linux audio and have a good superficial understanding of what's available in the Linux world for audio. To keep this thread on topic, I've mentioned to Karl H before but I guess it would be worthwile to mention here that there is an audio I/O library called PortAudio. It is cross platform in the sense that it is a common API for audio I/O across Windows, Linux, MacOS X and other UNIXes. I'm part of a OSS project called Audacity, which uses PortAudio exclusively for all audio I/O. I have it running successfully on Linux, MacOS X and Windows, all compiled fr...

...original example around the OSS audio interface used on several free unix-like operating systems, which immediately excludes win32 and MacOS, even though it used SDL to display the frames. SDL also has audio support, and is quite widely ported. splayer replaces the OSS audio interface with the PortAudio(.com) library, which aims to be crossplatform, and somewhat uniquely offers latency reporting which greatly simplifies sync calculations. Unfortunately portaudio isn't widely installed, is big, and isn't being maintained very actively. So it's not may favorite dependency, and adds...

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 sta...

...how I play it after comparing the captured data with the original file there is always difference in the audio length (for 18 sec of audio there is more than 250 ms of difference). Which of course breaks echocancellation. I've tried playing the audio through mmsystem, directsound also using portaudio lib. The only way of playing audio correctly was using audacity binary version for windows. I've also tried compiling audacity from source and plying with it - and again the problem persists. I've also determined that with audacity binary version that if the sound is too load, I've p...

...aven't been through the archives yet, and perhaps my answer lies there, if indeed it does, perhaps I could be directed as to which month to review. I'm working with a video game engine, which makes use of openAL for playback. It does not support audio capture so I have been working with portaudio to handle this for me as its multiplatform like the engine I'm working with. What I am trying to accomplish, is to record, encode, send to server, relay to client(s), decode, playback. My interest is in what to use for playback. I could use portaudio, which supports playback, it also appears...

Hi, anyone knows how i can get the input from a mircophone as a byte-array stream in VC++ ?? So that i can encode it with speex an send it away. The second thing is, to decode the speex frame and play it on the speakers. It would be helpfull if you can give me a link to a site which explains this topic an include some littel code sampels. Thanks. Best regards Sören Krings mailto:spontexx@web.de
