Functions ¶

func GetMetadata ¶

func GetMetadata(path, mimeType string) (*api.AudioFile, *api.Meta, error)

func GuessMetadata ¶

func GuessMetadata(path string) (*api.AudioFile, *api.Meta, error)

Types ¶

type FLAC ¶

type FLAC struct{}

func (FLAC) GetMetadata ¶

func (f FLAC) GetMetadata(path string) (*api.AudioFile, *api.Meta, error)

ExtractMetadata reads a (local) FLAC file and returns audio encoding parameters and song metadata as two separate objects.

type MP3 ¶

type MP3 struct{}

func (MP3) GetMetadata ¶

func (m MP3) GetMetadata(path string) (*api.AudioFile, *api.Meta, error)

type MetadataExtractor ¶

type MetadataExtractor interface {
	GetMetadata(path string) (*api.AudioFile, *api.Meta, error)
}

type MpegFrameHeader ¶

type MpegFrameHeader []byte

func NewMpegFrameHeader ¶

func NewMpegFrameHeader() MpegFrameHeader

func ReadMpegFrame ¶

func ReadMpegFrame(r io.Reader) (MpegFrameHeader, []byte)

ReadMpegFrame returns the next frame header and data in the input stream. Note that this function makes no attempt at decoding the actual MPEG bitstream.

func (MpegFrameHeader) MpegLayer ¶

func (hdr MpegFrameHeader) MpegLayer() int

func (MpegFrameHeader) MpegVersion ¶

func (hdr MpegFrameHeader) MpegVersion() int

func (MpegFrameHeader) Padding ¶

func (hdr MpegFrameHeader) Padding() int

func (MpegFrameHeader) SampleRate ¶

func (hdr MpegFrameHeader) SampleRate() int
