Types

type Mixer

type Mixer struct {
	// contains filtered or unexported fields
}

Mixer summs up multiple channels of messages into a single channel.

func New

func New() *Mixer

New returns new mixer.

func (*Mixer) Flush

func (m *Mixer) Flush(sourceID string) error

Flush mixer data for defined source.

func (*Mixer) Interrupt

func (m *Mixer) Interrupt(sourceID string) error

Interrupt impliments pipe.Interrupter.

func (*Mixer) Pump

func (m *Mixer) Pump(outputID string) (func(bufferSize int) ([][]float64, error), int, int, error)

Pump returns a pump function which allows to read the out channel.

func (*Mixer) Reset

func (m *Mixer) Reset(sourceID string) error

Reset resets the mixer for another run.

func (*Mixer) Sink

func (m *Mixer) Sink(inputID string, sampleRate, numChannel int) (func([][]float64) error, error)

Sink registers new input. SampleRate and NumChannels are propagated here, due to that Sink pipes should be called before Pump.
