Member Function Documentation

int audiere::MixerStream::getLength (    )  [virtual]

Returns : number of frames in the stream, or 0 if the stream is not seekable Implements audiere::OutputStream. Definition at line 223 of file device_mixer.cpp.

float audiere::MixerStream::getPan (    )  [virtual]

Get current pan. Implements audiere::OutputStream. Definition at line 196 of file device_mixer.cpp. References audiere::RefPtr< MixerDevice >::get(), and SYNCHRONIZED.

float audiere::MixerStream::getPitchShift (    )  [virtual]

Get current pitch shift. Defaults to 1.0. Implements audiere::OutputStream. Definition at line 210 of file device_mixer.cpp. References audiere::RefPtr< MixerDevice >::get(), and SYNCHRONIZED.

int audiere::MixerStream::getPosition (    )  [virtual]

Returns the current position within the sample source. Returns : current position in frames Implements audiere::OutputStream. Definition at line 236 of file device_mixer.cpp. References audiere::RefPtr< MixerDevice >::get(), and SYNCHRONIZED.

bool audiere::MixerStream::getRepeat (    )  [virtual]

Returns : true if the stream is repeating Implements audiere::OutputStream. Definition at line 168 of file device_mixer.cpp. References audiere::RefPtr< MixerDevice >::get(), and SYNCHRONIZED.

float audiere::MixerStream::getVolume (    )  [virtual]

Gets the current volume. Returns : current volume of the output stream Implements audiere::OutputStream. Definition at line 182 of file device_mixer.cpp. References audiere::RefPtr< MixerDevice >::get(), and SYNCHRONIZED.

bool audiere::MixerStream::isPlaying (    )  [virtual]

Returns : true if the output stream is playing, false otherwise Implements audiere::OutputStream. Definition at line 147 of file device_mixer.cpp. References audiere::RefPtr< MixerDevice >::get(), and SYNCHRONIZED.

bool audiere::MixerStream::isSeekable (    )  [virtual]

Returns : true if the stream is seekable, false otherwise Implements audiere::OutputStream. Definition at line 217 of file device_mixer.cpp.

void audiere::MixerStream::play (    )  [virtual]

Start playback of the output stream. If the stream is already playing, this does nothing. Implements audiere::OutputStream. Definition at line 133 of file device_mixer.cpp. References audiere::RefPtr< MixerDevice >::get(), and SYNCHRONIZED.

void audiere::MixerStream::reset (    )  [virtual]

Reset the sample source or buffer to the beginning. On seekable streams, this operation is equivalent to setPosition(0). On some output streams, this operation can be moderately slow, as up to several seconds of PCM buffer must be refilled. Implements audiere::OutputStream. Definition at line 154 of file device_mixer.cpp. References audiere::RefPtr< MixerDevice >::get(), and SYNCHRONIZED.

void audiere::MixerStream::setPan (  float    pan )  [virtual]

Set current pan. Parameters: pan  -1.0 = left, 0.0 = center (default), 1.0 = right Implements audiere::OutputStream. Definition at line 189 of file device_mixer.cpp. References audiere::RefPtr< MixerDevice >::get(), and SYNCHRONIZED.

void audiere::MixerStream::setPitchShift (  float    shift )  [virtual]

Set current pitch shift. Parameters: shift  can range from 0.5 to 2.0. default is 1.0. Implements audiere::OutputStream. Definition at line 203 of file device_mixer.cpp. References audiere::RefPtr< MixerDevice >::get(), and SYNCHRONIZED.

void audiere::MixerStream::setPosition (  int    position )  [virtual]

Sets the current position within the sample source. If the stream is not seekable, this method does nothing. Parameters: position  current position in frames Implements audiere::OutputStream. Definition at line 229 of file device_mixer.cpp. References audiere::RefPtr< MixerDevice >::get(), and SYNCHRONIZED.

void audiere::MixerStream::setRepeat (  bool    repeat )  [virtual]

Set whether the output stream should repeat. Parameters: repeat  true if the stream should repeat, false otherwise Implements audiere::OutputStream. Definition at line 161 of file device_mixer.cpp. References audiere::RefPtr< MixerDevice >::get(), and SYNCHRONIZED.

void audiere::MixerStream::setVolume (  float    volume )  [virtual]

Sets the stream's volume. Parameters: volume  0.0 = silence, 1.0 = maximum volume (default) Implements audiere::OutputStream. Definition at line 175 of file device_mixer.cpp. References audiere::RefPtr< MixerDevice >::get(), and SYNCHRONIZED.

void audiere::MixerStream::stop (    )  [virtual]

Stop playback of the output stream. If the stream is already stopped, this does nothing. Implements audiere::OutputStream. Definition at line 140 of file device_mixer.cpp. References audiere::RefPtr< MixerDevice >::get(), and SYNCHRONIZED.
