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
Create an instance of MPEG::Properties with the data read from the MPEG::File file.
| virtual TagLib::MPEG::Properties::~Properties | ( | ) | [virtual] |
Destroys this MPEG Properties instance.
Member Function Documentation
| virtual int TagLib::MPEG::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.
| Header::ChannelMode TagLib::MPEG::Properties::channelMode | ( | ) | const |
Returns the channel mode for this frame.
| virtual int TagLib::MPEG::Properties::channels | ( | ) | const [virtual] |
Returns the number of audio channels.
Implements TagLib::AudioProperties.
| bool TagLib::MPEG::Properties::isCopyrighted | ( | ) | const |
Returns true if the copyrighted bit is set.
| bool TagLib::MPEG::Properties::isOriginal | ( | ) | const |
Returns true if the "original" bit is set.
| int TagLib::MPEG::Properties::layer | ( | ) | const |
Returns the layer version. This will be between the values 1-3.
| virtual int TagLib::MPEG::Properties::length | ( | ) | const [virtual] |
Returns the length of the file in seconds.
Implements TagLib::AudioProperties.
| bool TagLib::MPEG::Properties::protectionEnabled | ( | ) | const |
Returns true if the MPEG protection bit is enabled.
| virtual int TagLib::MPEG::Properties::sampleRate | ( | ) | const [virtual] |
Returns the sample rate in Hz.
Implements TagLib::AudioProperties.
| Header::Version TagLib::MPEG::Properties::version | ( | ) | const |
Returns the MPEG Version of the file.
| const XingHeader* TagLib::MPEG::Properties::xingHeader | ( | ) | const |
Returns a pointer to the XingHeader if one exists or null if no XingHeader was found.
