Detailed Description

An implementation of audio property reading for MP3.

This reads the data from an MPEG Layer III stream found in the AudioProperties API.

Constructor & Destructor Documentation

Properties() [1/2]

TagLib::MPEG::Properties::Properties	(	File *	file,
		ReadStyle	style = Average
	)

Create an instance of MPEG::Properties with the data read from the MPEG::File file.

~Properties()

TagLib::MPEG::Properties::~Properties ( )

override

Destroys this MPEG Properties instance.

Properties() [2/2]

TagLib::MPEG::Properties::Properties ( const Properties &  )

delete

Member Function Documentation

bitrate()

int TagLib::MPEG::Properties::bitrate ( ) const

overridevirtual

Returns the average bit rate of the file in kb/s.

Reimplemented from TagLib::AudioProperties.

channelConfiguration()

Header::ChannelConfiguration TagLib::MPEG::Properties::channelConfiguration

(

)

const

Returns the MPEG-4 channel configuration.

channelMode()

Header::ChannelMode TagLib::MPEG::Properties::channelMode

(

)

const

Returns the channel mode for this frame.

channels()

int TagLib::MPEG::Properties::channels ( ) const

overridevirtual

Returns the number of audio channels.

Implements TagLib::AudioProperties.

isADTS()

bool TagLib::MPEG::Properties::isADTS

(

)

const

Returns true for an Audio Data Transport Stream (ADTS), usually AAC.

isCopyrighted()

bool TagLib::MPEG::Properties::isCopyrighted

(

)

const

Returns true if the copyrighted bit is set.

isOriginal()

bool TagLib::MPEG::Properties::isOriginal

(

)

const

Returns true if the "original" bit is set.

layer()

int TagLib::MPEG::Properties::layer

(

)

const

Returns the layer version. This will be between the values 1-3.

lengthInMilliseconds()

int TagLib::MPEG::Properties::lengthInMilliseconds ( ) const

overridevirtual

xingHeader()

const XingHeader * TagLib::MPEG::Properties::xingHeader

(

)

const

Returns a pointer to the Xing/VBRI header if one exists or null if no Xing/VBRI header was found.
