3D Sound Support Classes(3)					       Coin					       3D Sound Support Classes(3)

NAME
3D Sound Support Classes - Classes class SoAudioDevice The SoAudioDevice class is used to control an audio device. The SoAudioDevice class is responsible for initialization of an audio device, as well as enabling and disabling sound. It is a singleton class. " class SoListener The SoListener class defines listener attributes used when rendering sound. When rendering geometry, one needs to have a camera defining certain attributes related to vieweing. The SoListener plays a similar role when it comes to rendering audio. " class SoVRMLAudioClip The SoVRMLAudioClip class is used to load and store audio data. Audio data is loaded using the simage library, so make sure you have built the simage library with support for the audio file formats you intend to use (libogg, libvorbis and libvorbisfile for OggVorbis, libsndfile for WAV and several other formats). " class SoVRMLSound The SoVRMLSound class is used to represent a sound source. The detailed class documentation is taken verbatim from the VRML97 standard (ISO/IEC 14772-1:1997). It is copyright The Web3D Consortium, and is used by permission of the Consortium: " Detailed Description Author Generated automatically by Doxygen for Coin from the source code.

NAME
SoAudioDevice - The SoAudioDevice class is used to control an audio device. The SoAudioDevice class is responsible for initialization of an audio device, as well as enabling and disabling sound. It is a singleton class. SYNOPSIS
#include <Inventor/misc/SoAudioDevice.h> Public Member Functions SbBool init (const SbString &devicetype, const SbString &devicename) SbBool enable () void disable () SbBool isEnabled () SbBool haveSound () void setGain (float gain) void mute (SbBool mute=TRUE) Static Public Member Functions static SoAudioDevice * instance () Detailed Description The SoAudioDevice class is used to control an audio device. The SoAudioDevice class is responsible for initialization of an audio device, as well as enabling and disabling sound. It is a singleton class. The application programmer does not need to use this class directly, as audio support is enabled by default, and the default settings are reasonable. Coin uses OpenAL (http://www.openal.org/, http://developer.soundblaster.com [Games section]) to render audio. OpenAL should work with any soundcard, and on most modern operating systems (including Unix, Linux, IRIX, *BSD, Mac OS X and Microsoft Windows). 2 speaker output is always available, and on some OS and soundcard combinations, more advanced speaker configurations are supported. On Microsoft Windows, OpenAL can use DirectSound3D to render audio, thus supporting any speaker configuration the current DirectSound3D driver supports. Configuring speakers are done through the soundcard driver, and is transparent to both Coin and OpenAL. Member Function Documentation SoAudioDevice * SoAudioDevice::instance () [static] Returns a pointer to the SoAudioDevice class, which is a singleton. SbBool SoAudioDevice::init (const SbString &devicetype, const SbString &devicename) Initializes the audio device. Currently, the only supported devicetype is 'OpenAL'. The supported devicename depends on the OS and on installed soundcards and drivers. On Microsoft Windows, supported device names are 'DirectSound3D', 'DirectSound', and 'MMSYSTEM'. See OpenAL documentation (available from http://www.openal.org/) for further information. The application programmer may override the default setting by calling this method with the wanted device type and name. The user can also control which devicename OpenAL uses by setting the COIN_SOUND_DRIVER_NAME environment variable. On Microsoft Windows, the default driver name is 'DirectSound3D', which should normally be what the user wants. SbBool SoAudioDevice::enable () Enables sound void SoAudioDevice::disable () Disables sound. Effectively silencing all audio output. SbBool SoAudioDevice::isEnabled (void) Returns TRUE if audio is enabled. SbBool SoAudioDevice::haveSound () returns true if the audio device has been initialized successfully.
