Member Function Documentation

virtual int TagLib::MP4::Properties::bitrate ( ) const

Returns the most appropriate bit rate for the file in kb/s. For constant bitrate formats this is simply the bitrate of the file. For variable bitrate formats this is either the average or nominal bitrate.

Implements TagLib::AudioProperties.

virtual int TagLib::MP4::Properties::bitsPerSample ( ) const
virtual int TagLib::MP4::Properties::channels ( ) const

Returns the number of audio channels.

Implements TagLib::AudioProperties.

Codec TagLib::MP4::Properties::codec ( ) const

Audio codec used in the MP4 file.

bool TagLib::MP4::Properties::isEncrypted ( ) const
virtual int TagLib::MP4::Properties::length ( ) const

Returns the length of the file in seconds.

Implements TagLib::AudioProperties.

virtual int TagLib::MP4::Properties::sampleRate ( ) const

Returns the sample rate in Hz.

Implements TagLib::AudioProperties.
