Functions

func Load

func Load(r io.Reader) (audio.Audio, error)

Load loads wav data from the incoming reader as an audio

func ReadFormat

func ReadFormat(r io.Reader) (audio.Format, error)

Read reads a WAV header from the provided reader, returning the PCM format and leaving the PCM data in the reader available for consumption.

func Save

func Save(r io.ReadWriter, a audio.Audio) error

Save will eventually save an audio encoded as a wav to the given writer

Types

Data stores the raw information contained in a wav file

func Read

func Read(r io.Reader) (Data, error)

Read returns raw wav data from an input reader

func ReadData

func ReadData(r io.Reader) (Data, error)
