Member Function Documentation

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.

See also
codecName()
codecDescription()
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.

codec()
codecName()
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.

codec()
codecDescription()
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.

Note
This method is just an alias of lengthInSeconds().

Implements TagLib::AudioProperties.

int TagLib::ASF::Properties::lengthInMilliseconds ( ) const

Returns the length of the file in milliseconds.

See also
lengthInSeconds()
int TagLib::ASF::Properties::lengthInSeconds ( ) const

Returns the length of the file in seconds. The length is rounded down to the nearest whole second.

See also
lengthInMilliseconds()
virtual int TagLib::ASF::Properties::sampleRate ( ) const
virtual

Returns the sample rate in Hz.

Implements TagLib::AudioProperties.
