Types

type ChainGenerator

type ChainGenerator struct {
	GeneratorFuncs []GeneratorFunction
}

func (*ChainGenerator) ChainFunc

func (g *ChainGenerator) ChainFunc(stat float64, delta float64) float64

type GeneratorFunction

type GeneratorFunction func(stat float64, delta float64) float64

type OscStream

type OscStream struct {

	OscFunc GeneratorFunction
}

create stream which will produce infinite osciator tone with the given frequency use other wrappers of this package to change amplitude or add time limit sampleRate must be at least two times grater then frequency, otherwise this function will return an error

func (*OscStream) Err

func (c *OscStream) Err() error

func (*OscStream) Stream

func (c *OscStream) Stream(buf [][2]float64) (int, bool)
