Types

type FrameHeader

type FrameHeader uint32

A mepg1FrameHeader is MPEG1 Layer 1-3 frame header

func Read

func Read(source FullReader, position int64) (h FrameHeader, startPosition int64, err error)

func (FrameHeader) BitrateIndex

func (f FrameHeader) BitrateIndex() int

BirateIndex returns the bitrate index stored in position 15,12

func (FrameHeader) Copyright

func (f FrameHeader) Copyright() int

Copyright returns whether or not this recording is copywritten - stored in position 3

func (FrameHeader) Emphasis

func (f FrameHeader) Emphasis() int

Emphasis returns emphasis - the emphasis indication is here to tell the decoder that the file must be de-emphasized - stored in position 0,1

func (FrameHeader) FrameSize

func (f FrameHeader) FrameSize() int

func (FrameHeader) ID

func (f FrameHeader) ID() consts.Version

ID returns this header's ID stored in position 20,19

func (FrameHeader) IsValid

func (f FrameHeader) IsValid() bool

IsValid returns a boolean value indicating whether the header is valid or not.

func (FrameHeader) Layer

func (f FrameHeader) Layer() consts.Layer

Layer returns the mpeg layer of this frame stored in position 18,17

func (FrameHeader) Mode

func (f FrameHeader) Mode() consts.Mode

Mode returns the channel mode, stored in position 7,6

func (FrameHeader) NumberOfChannels

func (f FrameHeader) NumberOfChannels() int

func (FrameHeader) OriginalOrCopy

func (f FrameHeader) OriginalOrCopy() int

OriginalOrCopy returns whether or not this is an Original recording or a copy of one - stored in position 2

func (FrameHeader) PaddingBit

func (f FrameHeader) PaddingBit() int

PaddingBit returns the padding bit stored in position 9

func (FrameHeader) PrivateBit

func (f FrameHeader) PrivateBit() int

PrivateBit returns the private bit stored in position 8 - this bit may be used to store arbitrary data to be used by an application

func (FrameHeader) ProtectionBit

func (f FrameHeader) ProtectionBit() int

ProtectionBit returns the protection bit stored in position 16

func (FrameHeader) SamplingFrequency

func (f FrameHeader) SamplingFrequency() consts.SamplingFrequency

SamplingFrequency returns the SamplingFrequency in Hz stored in position 11,10

func (FrameHeader) UseIntensityStereo

func (f FrameHeader) UseIntensityStereo() bool

UseIntensityStereo returns a boolean value indicating whether the frame uses intensity stereo.

func (FrameHeader) UseMSStereo

func (f FrameHeader) UseMSStereo() bool

UseMSStereo returns a boolean value indicating whether the frame uses middle/side stereo.

type FullReader

type FullReader interface {
	ReadFull([]byte) (int, error)
}
