Member Function Documentation

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

virtual

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

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

virtual

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
