AudioProperties (ReadStyle style) | |
An implementation of audio property reading for MP3.
This reads the data from an MPEG Layer III stream found in the AudioProperties API.
Create an instance of MPEG::Properties with the data read from the MPEG::File file.
|
virtual |
Destroys this MPEG Properties instance.
|
virtual |
Returns the average bit rate of the file in kb/s.
Implements TagLib::AudioProperties.
Header::ChannelMode TagLib::MPEG::Properties::channelMode | ( | ) | const |
Returns the channel mode for this frame.
|
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 |
Returns the length of the file in seconds. The length is rounded down to the nearest whole second.
Implements TagLib::AudioProperties.
int TagLib::MPEG::Properties::lengthInMilliseconds | ( | ) | const |
Returns the length of the file in milliseconds.
int TagLib::MPEG::Properties::lengthInSeconds | ( | ) | const |
Returns the length of the file in seconds. The length is rounded down to the nearest whole second.
bool TagLib::MPEG::Properties::protectionEnabled | ( | ) | const |
Returns true if the MPEG protection bit is enabled.
|
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 Xing/VBRI header if one exists or null if no Xing/VBRI header was found.
