Added the ability for the user to provide a DataSourceFactory, which cAudio will use to get audio data. This interface can be overridden to provide cAudio the ability to read from zip archives, TCP streams, potentially any location. DataSourceFactories can also be prioritized.
Made the existing FileSource a factory and registered it by default with the manager. If the user wishes to prevent cAudio from reading from disk, unRegister the "FileSystem" data source.
Made tutorials conform with the changes to the API.
Added conversion functions from our audio format enum to OpenAL's in preparation for supporting more formats.
Reorganized cAudio defines, made it easier to access some compile time parameters.
Fixed a bug where a source could not be played again after it reached the end of its audio stream.
Added better checking for sources. IsValid() should provide a more useful indication of whether a source is usable.
Added error checking and logging to cAudioCapture.
Prevented initializing of cAudioManager until shutdown() has been called.
Added a tutorial for Audio Effects.
Added a footsteps sound for showing off Audio Effects.
Moved the default compile location for the main library to lib/. The msvc project will copy the cAudio.dll to bin/win32-visual/
Changed the 3d tutorial to use the move convenience function in order to have proper doppler effects.
Added relative seek ability to cAudio source.
Updated decoders to have a flag if the data they are working with is valid for their decoder (isValid).
Added reference counting to IAudio, IAudioDecoder, and IDataSource
Added better error checking in cAudio sources and they will do a better job of detecting if they are invalid.
Fixed the spelling on cWavAudioDecoderFactory.h
Ogg decoder support for the isValid check.
Time seek ability added to cRawDecoder
Rewrote cWavDecoder. It will now read slightly malformed wav files (and conforms to the wav spec), no longer has a bug where 8 bit mono audio samples will play twice as fast as 16 bit mono samples, proper bounds checking to make sure only the audio data is sent to the audio source, and time seeking abilities. The decoder does not support channels over 2, compressed wavs, wavs with more than 1 data or fmt block, or any other blocks that may be present in a wav file. All unsupported blocks will be ignored.
Added a convenience function (move()) to the cAudio source, making it easier to move a source and do velocity for doppler effects with a single call.
Internally, audio sources are now stored in an std::vector for better performance. This change also makes it so that it is no longer required for the user to name a source. The user can pass NULL to name to avoid naming it.
Some documentation fixes.
Added a stress test app, allowing users and developers test how well cAudio performs under pressure.
Removed an unnecessary include in cAudioManager.h
Added a define to set the number of buffers used by an audio source
Added the last of the previously unsupported OpenAL source parameters (Cones, attenuation tweaking, max/min volume, and rolloff factor)
Cleaned up the implementation of cAudio source. It no longer keeps a redundant copy of the state information and functions are now in order that they are defined. Some functions have been renamed to be clearer.
Other changes throughout the code to support the changes to the cAudio source.
Changed song used by Tutorial1_2DSound.
Added some comments.
Changed cVector3 to use a custom Episilon instead of including float.h (less bloat)
Added debug log entries to cAudio
Allowed cOggDecoder to return error values from decoding. cAudio now handles those errors a little better.
Updated logger to allow a user to create callbacks to receive log messages
Logger also gives more information, time the message was sent, the source, the importance, and the message itself.
User can now query playback devices and specify the device for the audio manager to use. The audio manager is no longer a singleton, although creating multiple managers is not advised.
Clean up and optimization of manager initialization code.
IAudioCapture can now be told which device to capture audio from. The user can also create multiple IAudioCaptures to capture audio from multiple sources at the same time.
Added additional error checking.
A seperate thread is used to capture audio now.
Defines added to allow a user to remove support for default codecs.
Made cAudio, cAudioCapture, cAudioManager and other classes thread safe.
Made cAudioManager use a seperate update thread by default.
Added cAudioSleep, a cross-platform sleep() function
Moved global defines to cAudioDefines
Added defines to disable thread safety or the internal update thread if the user wishes it
Updated tutorials to reflect the changes made
Added a raw audio decoder, allowing raw audio to be played if the format and frequency is known. Will also load from .raw files on disk, but will assume the format is 16 bit mono and the frequency is 22050 hz
Added a tutorial to show how recording and playback can be done.
Added the ability for the user to unregister audio codecs that they will not be using. Also added methods to test for the existance of a decoder and get the decoder factory back.
Moved cVector3.h to include instead of Headers to make using it in user projects easier (one less include path)
Moved the audio format enum to its own header file.
Small fix in the wav decoder to prevent the file header from being played as audio data.
Updated tutorials to fix minor bugs and pathing issues. Also fixed crash bug on failure to create the audio object.
Added msvc projects for all tutorials.
Updated the listener class to be self contained and only handle stuff related to the OpenAL listener. It does NOT init OpenAL anymore, that has been moved to cAudioManager.
Extended the listener class to support all settings that native OpenAL supports.
Cleaned up cFileSource and fixed a crash bug on NULL file handle
Fixed returning bad audio buffer chunk sizes from the cOggDecoder on errors in the ogg stream
Seeking can now be down in fractions of a second now, changed the seconds field from int to float
Fixed various odd formatting.
Fixed potential crash bug in cMemorySource if memory could not be allocated.
cMemorySource will no longer clear the buffer you give to it before filling it with data. This prevents an overwrite from happening in case of error but the user should provide a zeroed buffer to cMemorySource anyway for safety.
Relative seeking is now supported by cOggDecoder.
