Member Function Documentation

◆ configure_filters()

bool AudioManager::configure_filters ( FilterProperties config)
virtual

Configures the global DSP filter chain.

There is no guarantee that any given configuration will be supported by the implementation. The only way to find out what's supported is to call configure_filters. If it returns true, the configuration is supported.

Definition at line 194 of file audioManager.cxx.

References FilterProperties::get_config(), and update().

Referenced by shutdown().

◆ get_dls_pathname()

Filename AudioManager::get_dls_pathname ( )
static

Returns the full pathname to the DLS file, as specified by the Config.prc file, or the default for the current OS if appropriate.

Returns empty string if the DLS file is unavailable.

Definition at line 299 of file audioManager.cxx.

References Filename::from_os_specific(), VirtualFileSystem::get_global_ptr(), Filename::make_true_case(), VirtualFileSystem::resolve_filename(), and set_speaker_configuration().

Referenced by update().

◆ set_speaker_configuration()

void AudioManager::set_speaker_configuration ( LVecBase3 speaker1,
LVecBase3 speaker2 = NULL,
LVecBase3 speaker3 = NULL,
LVecBase3 speaker4 = NULL,
LVecBase3 speaker5 = NULL,
LVecBase3 speaker6 = NULL,
LVecBase3 speaker7 = NULL,
LVecBase3 speaker8 = NULL,
LVecBase3 speaker9 = NULL 
)
virtual

For use only with Miles.

Definition at line 359 of file audioManager.cxx.

Referenced by get_dls_pathname().

◆ shutdown()

void AudioManager::shutdown ( )
virtual

Call this at exit time to shut down the audio system.

This will invalidate all currently-active AudioManagers and AudioSounds in the system. If you change your mind and want to play sounds again, you will have to recreate all of these objects.

Reimplemented in OpenALAudioManager.

Definition at line 133 of file audioManager.cxx.

References AtomicAdjustDummyImpl::compare_and_exchange_ptr(), configure_filters(), and ReferenceCount::ref().

◆ update()

void AudioManager::update ( )
virtual

Must be called every frame.

Failure to call this every frame could cause problems for some audio managers.

Reimplemented in FmodAudioManager, and OpenALAudioManager.

Definition at line 211 of file audioManager.cxx.

References get_dls_pathname().
