An implementation of ASF audio properties.
Audio codec types can be used in ASF file.
TagLib::ASF::Properties::Properties | ( | ) |
Creates an instance of ASF::Properties.
virtual TagLib::ASF::Properties::~Properties | ( | ) | [virtual] |
Destroys this ASF::Properties instance.
virtual int TagLib::ASF::Properties::bitrate | ( | ) | const [virtual] |
Returns the average bit rate of the file in kb/s.
Implements TagLib::AudioProperties.
int TagLib::ASF::Properties::bitsPerSample | ( | ) | const |
Returns the number of bits per audio sample.
virtual int TagLib::ASF::Properties::channels | ( | ) | const [virtual] |
Returns the number of audio channels.
Implements TagLib::AudioProperties.
Codec TagLib::ASF::Properties::codec | ( | ) | const |
Returns the codec used in the file.
String TagLib::ASF::Properties::codecDescription | ( | ) | const |
Returns the codec description, typically contains the encoder settings, for example "VBR Quality 50, 44kHz, stereo 1-pass VBR" if available, otherwise an empty string.
String TagLib::ASF::Properties::codecName | ( | ) | const |
Returns the concrete codec name, for example "Windows Media Audio 9.1" used in the file if available, otherwise an empty string.
bool TagLib::ASF::Properties::isEncrypted | ( | ) | const |
Returns whether or not the file is encrypted.
virtual int TagLib::ASF::Properties::length | ( | ) | const [virtual] |
Returns the length of the file in seconds. The length is rounded down to the nearest whole second.
Implements TagLib::AudioProperties.
int TagLib::ASF::Properties::lengthInMilliseconds | ( | ) | const |
Returns the length of the file in milliseconds.
Reimplemented from TagLib::AudioProperties.
int TagLib::ASF::Properties::lengthInSeconds | ( | ) | const |
Returns the length of the file in seconds. The length is rounded down to the nearest whole second.
Reimplemented from TagLib::AudioProperties.
virtual int TagLib::ASF::Properties::sampleRate | ( | ) | const [virtual] |
Returns the sample rate in Hz.
Implements TagLib::AudioProperties.
