Overview ¶

Package render holds various mlsic.Renderer implementations. It should be used along top package compositional algos.

Types ¶

type Aiff ¶

type Aiff struct {
	// Filepath `/path/to/directory` where the file should be saved.
	Filepath string
}

Aiff holds relevant information for encoding and saving .aiff files out of audio.PCMBuffer.

func (*Aiff) Render ¶

func (a *Aiff) Render(pcmBuffer []*audio.PCMBuffer) error

Render accepts a slice of audio.PCMBuffer and creates out of each one of them a mono .aiff file named /path/to/file/0.aiff for the first channel, /path/to/file/1.aiff for the second etc.

type PortAudio ¶

type PortAudio struct {
	// Latency is part of the portaudio.StreamDeviceParameters.
	Latency time.Duration
	// OutputDevice is the device to be used.
	OutputDevice *portaudio.DeviceInfo
	// BufferSize is part of the portaudio.StreamDeviceParameters.
	BufferSize int
}

PortAudio implements mlsic.Renderer and holds all necessary dependencies for setting up PortAudio.

func NewPortAudio ¶

func NewPortAudio(opts ...PortAudioOption) (pa *PortAudio, err error)

NewPortAudio will try to initialize with a portaudio.DefaultOutputDevice() with the default buffer size set at 512 abd latency 10.

func (*PortAudio) Render ¶

func (p *PortAudio) Render(pcmBuffer []*audio.PCMBuffer) error

Render will render for as many channels as len(pcmBuffer). Samplerate is set by the first channel's (pcmBuffer[0]) format.

type PortAudioOption ¶

type PortAudioOption func(*PortAudio)

PortAudioOption if a custom type function that accepts *PortAudio and is used WithXXX PortAudio options functions.

func WithBufferSize ¶

func WithBufferSize(customSize int) PortAudioOption

WithBufferSize sets PortAudio's buffer size.

func WithLatency ¶

func WithLatency(latency time.Duration) PortAudioOption

WithLatency sets PortAudio's latency.

func WithOutputDevice ¶

func WithOutputDevice(device *portaudio.DeviceInfo) PortAudioOption

WithOutputDevice set custom output device.

type Wav ¶

type Wav struct {
	// Filepath `/path/to/directory` where the file should be saved.
	Filepath string
	// Meta holds .wav file metadata.
	Meta *wav.Metadata
}

Wav holds relevant information for encoding and saving .wav files out of audio.PCMBuffer.

func (*Wav) Render ¶

func (w *Wav) Render(pcmBuffer []*audio.PCMBuffer) error

Render accepts a slice of audio.PCMBuffer and creates out of each one of them a mono .wav file named /path/to/file/0.wav for the first channel, /path/to/file/1.wav for the second etc.
