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

-----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

Hello, Need some help using the speex_echo_cancel. I've read the documentation about the speex_echo_cancellation function: speex_echo_cancellation(echo_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

>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 only intended to be a Win32 executable. Note that it is in a directory

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, both are different functions called in different times directly from

Hi Guys, I'd reflect Vieri's question actually, because there must be a way of doing it? Maybe not with ICES, but maybe combines with JackIT? The reason for my interest is I work in a radio station in Spain, and because of the geographics where I am we have to relay around a lot. If there is a way of sending an incoming feed into ICES, and sending it out in various directions, would

Hi, I had downlaoded iaxclient-2.0.2 and complie project *\iaxclient-2.0.2\contrib\win\vs2005* ** It gives many83 fatal and file missing error of file missing Error 1 fatal error C1083: Cannot open include file: 'portaudio.h': No such file or directory d:\mohit\asterisk\iaxclient-2.0.2\iaxclient-2.0.2\lib\portmixer\px_win_wmme\px_win_wmme.c 40 Error 2 fatal error C1083: Cannot open

Hi. I'm new to icecast. I can see that IceS can source an input MIC, for example, from a sound card. Can it also output a playlist to a sound card (to the speakers)? If so, how?

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, does anybody has ran echocancellation successfully on windows ? I have a problem playing audio there. If you play a wav file no mater 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

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* input, void* output, unsigned

Hello, I am writing a program that decodes Ogg Vorbis and output to the hardware. I followed the decoding examples and got the bytes ready for output. I am looking for an audio output library on Windows. So far, I tried at DirectSound but it is quite complicated and requires lots of set up. I have several questions: 1. Does Libao work on Windows? 2. And Is there a simpler audio output library?

Alsa audio started working a couple of days ago with wine and then stopped working yesterday. Here is my experience. Pulseaudio cannot be removed any more. So I reinstalled the system and left it there. I compiled wine git and installed, and then installed DNS 10. Then I re-booted, ran killall pulseaudio in terminal, and started the program with winecfg's sound set to alsa. Everything
