Detailed Description

An implementation of audio property reading for MPC.

This reads the data from an MPC stream found in the AudioProperties API.

Constructor & Destructor Documentation

TagLib::MPC::Properties::Properties ( const ByteVector data,
long  streamLength,
ReadStyle  style = Average 
)

Create an instance of MPC::Properties with the data read from the ByteVector data.

This constructor is deprecated. It only works for MPC version up to 7.

TagLib::MPC::Properties::Properties ( File file,
long  streamLength,
ReadStyle  style = Average 
)

Create an instance of MPC::Properties with the data read directly from a MPC::File.

virtual TagLib::MPC::Properties::~Properties ( )
virtual

Destroys this MPC::Properties instance.

Member Function Documentation

int TagLib::MPC::Properties::albumGain ( ) const

Returns the album gain as an integer value, to convert to dB: albumGain in dB = 64.82 - (albumGain / 256)

int TagLib::MPC::Properties::albumPeak ( ) const

Returns the album peak as an integer value, to convert to dB: albumPeak in dB = albumPeak / 256 to convert to floating [-1..1]: albumPeak = 10^(albumPeak / 256 / 20)/32768.

virtual int TagLib::MPC::Properties::bitrate ( ) const
virtual

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

Implements TagLib::AudioProperties.

virtual int TagLib::MPC::Properties::channels ( ) const
virtual

Returns the number of audio channels.

Implements TagLib::AudioProperties.

virtual int TagLib::MPC::Properties::length ( ) const
virtual

Returns the length of the file in seconds.

The length is rounded down to the nearest whole second.

Note
This method is just an alias of lengthInSeconds().
Deprecated:
