Member Function Documentation

void gnash::sound::NullSoundHandler::mix	(	boost::int16_t *	outSamples,
		boost::int16_t *	inSamples,
		unsigned int	nSamples,
		float	volume
	)		[inline, virtual]

Mix nSamples from inSamples to outSamples, with given volume.

Parameters:

outSamples	The output samples buffer, to mix to. Must be big enough to contain nSamples. Can be larger.
inSamples	The input samples buffer, to mix in. It is non-const as this method *is* allowed to mess with content, for example to apply volume. TODO: why not applying volume upstream ?!
nSamples	The amount of samples to mix in.
volume	The volume to apply to input samples, as a fraction (0..1)

TODO: this interface says nothing about how many channels we're going to mix. It should, to be a sane interface. Maybe, a Mixer instance should be created, initialized with number of channels, at each fetching.

Implements gnash::sound::sound_handler.
