this is probably a dumb question, but I ned some help. I'm trying to get the Cortex Command ubuntu build to run on my computer. One of the (thankfully shared) libs it relies on is cAudio. I cloned myself the source and built the lib with no difficulties, but when I run the game, it says 'undefined symbol: getLogger', which is part of cAudio (defined at cAudio.cpp).

After building and installing the lib from source, if I run "strings /usr/local/lib/libcAudio.so | grep getLogger" I get nothing, but if I do the same on the compiled library the game shipped with, it is present.

Is there some configuration flag that disables the logging functionality? Thank you

Hi, im using the latest version of cAudio.
I modified the tutorial 1 for a test case, so it plays a mp3 file.
But my application crashes when loading the mp3 plugin, if I disable the plugin and play a .wav file eveything works fine.

cAudio 2.3.0 Tutorial 1: Basic 2D Audio.

Problem

When building on Linux the variable for threading gets set to 1 all through the CMake config, CMake headers and generated headers. No warnings or errors during compile but the audioManager does not get updated automatically as expected on a threaded version of the library.

Symptoms

All the examples, where the threaded library should make music play through to the end, requires an additional line of audioMgr->update() in the while(mysound->isPlaying()) block to work as expected.

Investigation

I followed the code to the point that I'm sure it's configured correctly and that pthreads gets included in the build. However I think the assistance of a main developer on this issue might get us to a resolution faster.

Solution

I'm prepared to spend time and effort on fixing this issue, seams logical since I'm building on Linux anyways, but would request the help of a developer to get into the code faster (no point in floundering around for a week ;o). Contact me if you can help. I'll get stuck in in the meanwhile...

Yep. It can be useful. Mainly because there is not an available forum. :-/

all includes and libs should be installed in CMAKE_INSTALL_PREFIX/[lib|include]

Problem:

    void cAudioManager::releaseAllSources()
    {
        cAudioMutexBasicLock lock(Mutex);
        size_t count = audioSources.size();
        for(size_t i=0; i<count; i++)
        {
            IAudioSource* source = audioSources[i];
            if(source)
                source->drop();
        }

As sources are dropped, they are erased from audioSources while count and i remain the same. This causes an index out of bounds exception sooner or later.

Solution:

void cAudioManager::releaseAllSources()
    {
        cAudioMutexBasicLock lock(Mutex);
        cAudioVector<IAudioSource*>::Type tempList(audioSources.begin(), audioSources.end());
        size_t count = audioSources.size();
        for(size_t i=0; i<count; i++)
        {
            IAudioSource* source = tempList[i];
            if(source)
                source->drop();
        }

Hello,

I found several problems compiling the cAudio statically
The main problems concern the use of STL and thread

Here are some examples of output (in Mac using the debugger)...

1. This example creates the file cymal2.wav, it plays back, the program terminates when the error appears:

thanks your lib..
I use stable 2.2 cAudio Verson then setDopplerVelocity will log invlalid enum

i google it .. and find
http://opensource.creative.com/pipermail/openal-devel/2005-October/003659.html

call setDopplerStrength, setDopplerVelocity functions
it will log OpenAL Error: Invalid Enum.

i find the answer.. QQ
alSourcef just support enums below lists in openal guide
AL_PITCH
AL_GAIN
AL_MIN_GAIN
AL_MAX_GAIN
AL_MAX_DISTANCE
AL_ROLLOFF_FACTOR
AL_CONE_OUTER_GAIN
AL_CONE_INNER_ANGLE
AL_CONE_OUTER_ANGLE
AL_REFERENCE_DISTANCE

In Effect Filter has the same problem..
alSourcei(Source, AL_DIRECT_FILTER, theFilter->getOpenALFilter());

MP3 seeking to specified time doesn't work correctly. It compares specified position (computed from bitrate) with position in compressed stream - IMHO it's not correct. After my own some changes it still not works :(

Not sure if this was submitted or if this is even a cAudio bug but I'm having trouble creating a large number of audio sources.
I essentially have a loop that calls cAudioManager::create repeatedly and it always crashes on sound #256

I'm passing the same filename and a different name at each iteration. I'm passing in false for stream. Code:

IAudioSource* sources[512];
const char fn = "myFile.ogg";
for (int i = 0; i < 512; i++)
{
    std::stringstream n;
    n << "Sound " << i;
    sources[i] = mgr->create(n.str().c_str(), fn, false);
}

I traced the execution and it seems to to be an openal error. Error code 40963. The error string is "Invalid Value". Seems like alGenSources in cAudioSource.cpp (line 51) is what is setting the error state as the state variable was true prior to the checkError() call that comes after the alGenSources call. Any ideas what's up?

I'm running on a develop build of cAudio from commit 86548b9

As a way to avoid the logging issues I have recieved I tried to use both CMake variables
CAUDIO_ENABLE_DEFAULT_FILE_LOGGER
CAUDIO_ENABLE_DEFAULT_CONSOLE_LOGGER
as a way to try to remove logging all together. However both binary files and cAudioEngineLog.html are output as they were before.

I believe this was caused by my pull request, anyways in a cAudio application there will occasionally be files created that have strange names (in binary?) that contain the normal contents of cAudioEngine.html however in different files. There must of been file I/O happening involving logging in a place that I did not find. This should be fixed at some point as it makes it difficult to create something professional with cAudio if it places files in the current directory, this was why I tried changing the logging system in the first place.
For bonus points the logging could of been redone with easyloggingpp if you ever get the time to move it over, this is a helpful logger because it outputs to the screen and to a file and is very configurable (plus it is MIT licensed). It would be great to include it as the logging system for the next version of cAudio.
https://github.com/easylogging/easyloggingpp/
It even supports colored output now :) If in the event you do not get time towards the end of the release of my game I will fix it myself, however it would be nice if upstream did this on it's own.

CMake/InstallDependencies.cmake returns immediately if not APPLE or WIN32
so the function 'install_all_targets' is never defined,
making it fail on 'install_all_targets(cAudio)' in cAudio/CMakeLists.txt

Hey FYI there is no way to configure the logging system for cAudio to put its log files in any place other than the current directory. I am working on a fork that will have the logging refractored in a way that the audio manager can configure which file the log files will be in, but it will be a default parameter so it should not break any interfaces at all.

When applying a min and maxDistance to an sound, the sound volume is not increasing or decreasing

in cAudio/src/cOpenALAudioDeviceList.cpp alext.h should be included as well. Otherwise ALC_ALL_DEVICES_SPECIFIER is not defined.

In order to keep CAudio alive, awake and alert. For technical support too.:-)

Thanks, Robert.

Shutdown cAudioManager will be crash in 2.2 version
if you have created audio source inside..
the audio source iterator will be erased in dropping
so releasing all resource will be crash..

I see the fixed at newest version but it's 2.3
could you create one stable branch to update the fix?
bcz I use the newest version in window .
it will compile error...below

Is this expected to work currently?

Hi all,
I've wrapped cAudio with a singleton manager that uses the audiomanager with the threaded update feature.

The interface that I inherit from IManagerEventHandler.h includes the virtual functions that can be overridden like "onUpdate()" but cAudioManager.cpp never actually fires the events although it does handle them all.

The fix is very simple, just one line, and I'll be happy to create a pull request from what I've modified to make it work in my case. However, I'm curious to hear if there's something obvious that I've missed with how this is supposed to work or whether it's always been left unimplemented for some reason.

In case you're interested, my wrapper has a music playlist which needs to be advanced at the end of a song and does things like fade outs when notified by the game engine thread. That's why I need to get the update event firing.

Cheers and thanks for cAudio!

Unicode support in cAudioString.h was broken on this commit:

Here is a patch to fix it (jeez, is it impossible to attach files??)

I'm looking into possibly packaging cAudio for Fedora.

It appears that you don't version libcAudio.so; would it be possible for you to start doing so upstream? Most downstream distributions want any shared libraries installed by packages to be versioned in order to better guarantee ABI compatibility; you can read Fedora's guidelines on the subject here.

cmake should make it very easy to version a library.

https://github.com/immortaly007/GSoundUnityPlugin/tree/master/GSoundUnity/GSoundUnity/gsound gsound support should be incorporated

https://github.com/netpipe/AgAudio if you want to provide a link to original cAudio in the readme. it works well for placing directly into games without linking just got native wav support working. hopefully a new midi player next month too.

I created a multithreading solution to play audio and render in my game engine. When I call cAudio::destroyAudioManager, I get the _Mycont was nullptr error, caused by cAudioManager::releaseAllSources

cmake needs updating to find openal properly. also we need a logo for cAudio

Wav decoder doesn't find "fmt " tag in a wav file because it searches for it every 4 bytes. But the junk chunk only have to be even, not necessarily a multiple of 4.
And it seems to be the same problem for the "data" tag.

A side effect is the crash of cAudio at line 288 in cAudioManager.cpp.

The source is first dropped at line 281, then it's dropped in IAudioDecoder's destructor (called at the end of cAudioManager::createAudioSource) and destroyed.
The "source" variable is not null at line 287 but point on an invalid memory segment, so the third called to drop() at line 288 crashed cAudio.

Example of not handled wav :

This is more of a request.

Tried compiling via msys2 but got:

cmake ../ -DCAUDIO_DEPENDENCIES_DIR=../Dependencies64/
System is unknown to cmake, create:
Platform/MINGW64_NT-6.1 to use this system

Can you please support compiling with msys2?

I've managed to get the Debug version of CAudio to build properly in Visual Studio, but every other mode fails to build, resulting in the same linkage issues I'm encountering in the 2.3.0 version.

Please fix.

Hello!

I keep getting "unresolved externals" errors while trying to compile CAudio in VS Express 2013.

Here's my log:
