Types

type Streamer

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

Streamer is an implementation of the beep.StreamCloser interface to provide access to the microphone through the malgo library.

func OpenStream

func OpenStream(ctx *malgo.AllocatedContext, deviceConfig malgo.DeviceConfig) (s *Streamer, format beep.Format, err error)

OpenStream opens a stream for the deviceConfig

func (*Streamer) Close

func (s *Streamer) Close() error

Close the stream

func (*Streamer) Err

func (s *Streamer) Err() error

Err returns an error that occurred during streaming. If no error occurred, nil is returned.

func (*Streamer) Start

func (s *Streamer) Start()

Start reading data from the microphone

func (*Streamer) Stop

func (s *Streamer) Stop()

Stop reading data from the microphone. reading can be resumed using the Start method

func (*Streamer) Stream

func (s *Streamer) Stream(samples [][2]float64) (int, bool)

Stream fills samples with the audio recorded with the microphone. Unless there is an error, this method will wait until samples is filled completely which may involve waiting for the OS to supply the data.
