Constructor & Destructor Documentation

Mixer()

roc::audio::Mixer::Mixer	(	core::BufferFactory< sample_t > &	buffer_factory,
		core::nanoseconds_t	frame_length,
		const audio::SampleSpec &	sample_spec
	)

Initialize.

Parameters

• buffer_factory is used to allocate a temporary buffer of samples
• frame_length defines the temporary buffer length used to read from, in nanoseconds
• sample_spec defines the sample spec taken from the audio signal

Member Function Documentation

add_input()

void roc::audio::Mixer::add_input

(

IFrameReader &

)

Add input reader.

read()

virtual bool roc::audio::Mixer::read ( Frame &  frame )

virtual

Read audio frame.

Remarks

Reads samples from every input reader, mixes them, and fills frame with the result.

Implements roc::audio::IFrameReader.

void roc::audio::Mixer::remove_input

(

IFrameReader &

)

Remove input reader.

valid()

bool roc::audio::Mixer::valid

(

)

const

Check if the mixer was succefully constructed.
