Overview

Package mp3 provides MP3 decoder.

On desktops and mobiles, a pure Go decoder is used. On browsers, a native decoder on the browser is used.

Types

type Stream

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

Stream is a decoded stream.

func Decode

func Decode(context *audio.Context, src audio.ReadSeekCloser) (*Stream, error)

Decode decodes MP3 source and returns a decoded stream.

Decode returns error when decoding fails or IO error happens.

Decode automatically resamples the stream to fit with the audio context if necessary.

Decode takes the ownership of src, and Stream's Close function closes src.

func (*Stream) Close

func (s *Stream) Close() error

Close is implementation of io.Closer's Close.

func (*Stream) Length

func (s *Stream) Length() int64

Length returns the size of decoded stream in bytes.

func (*Stream) Read

func (s *Stream) Read(buf []byte) (int, error)

Read is implementation of io.Reader's Read.

func (*Stream) Seek

func (s *Stream) Seek(offset int64, whence int) (int64, error)

Seek is implementation of io.Seeker's Seek.

func (*Stream) Size

func (s *Stream) Size() int64

Size is deprecated as of 1.6.0-alpha. Use Length instead.
