Detailed Description

This device plays back through PulseAudio, the simple direct media layer.

Constructor & Destructor Documentation

PulseAudioDevice()

PulseAudioDevice::PulseAudioDevice	(	const std::string &	name,
		DeviceSpecs	specs,
		int	buffersize = AUD_DEFAULT_BUFFER_SIZE )

Opens the PulseAudio audio device for playback.

Parameters

specs	The wanted audio specification.
buffersize	The size of the internal buffer.

Note

The specification really used for opening the device may differ.

Exceptions

Exception

Thrown if the audio device cannot be opened.
