Detailed Description

A connection to an audio device. Multiple output streams are mixed by the audio device to produce the final waveform that the user hears.

Each output stream can be independently played and stopped. They also each have a volume from 0.0 (silence) to 1.0 (maximum volume).

Member Function Documentation

virtual int audiere::OutputStream::getLength (   )  [pure virtual]

Returns: number of frames in the stream, or 0 if the stream is not seekable

virtual float audiere::OutputStream::getPan (   )  [pure virtual]

Get current pan.

virtual float audiere::OutputStream::getPitchShift (   )  [pure virtual]

Get current pitch shift. Defaults to 1.0.

virtual int audiere::OutputStream::getPosition (   )  [pure virtual]

Returns the current position within the sample source. Returns: current position in frames

virtual bool audiere::OutputStream::getRepeat (   )  [pure virtual]

Returns: true if the stream is repeating

virtual float audiere::OutputStream::getVolume (   )  [pure virtual]

Gets the current volume. Returns: current volume of the output stream

virtual bool audiere::OutputStream::isPlaying (   )  [pure virtual]

Returns: true if the output stream is playing, false otherwise

virtual bool audiere::OutputStream::isSeekable (   )  [pure virtual]

Returns: true if the stream is seekable, false otherwise

virtual void audiere::OutputStream::play (   )  [pure virtual]

Start playback of the output stream. If the stream is already playing, this does nothing.

virtual void audiere::OutputStream::reset (   )  [pure 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.

virtual void audiere::OutputStream::setPan (  float  pan  )  [pure virtual]

Set current pan. Parameters: pan  -1.0 = left, 0.0 = center (default), 1.0 = right

virtual void audiere::OutputStream::setPitchShift (  float  shift  )  [pure virtual]

Set current pitch shift. Parameters: shift  can range from 0.5 to 2.0. default is 1.0.

virtual void audiere::OutputStream::setPosition (  int  position  )  [pure 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

virtual void audiere::OutputStream::setRepeat (  bool  repeat  )  [pure virtual]

Set whether the output stream should repeat. Parameters: repeat  true if the stream should repeat, false otherwise

virtual void audiere::OutputStream::setVolume (  float  volume  )  [pure virtual]

Sets the stream's volume. Parameters: volume  0.0 = silence, 1.0 = maximum volume (default)

virtual void audiere::OutputStream::stop (   )  [pure virtual]

Stop playback of the output stream. If the stream is already stopped, this does nothing.
