Member Function Documentation

virtual int TagLib::Ogg::Opus::Properties::bitrate ( ) const

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::Ogg::Opus::Properties::channels ( ) const

Returns the number of audio channels.

Implements TagLib::AudioProperties.

int TagLib::Ogg::Opus::Properties::inputSampleRate ( ) const

The Opus codec supports decoding at multiple sample rates, there is no single sample rate of the encoded stream. This returns the sample rate of the original audio stream.

virtual int TagLib::Ogg::Opus::Properties::length ( ) const

Returns the length of the file in seconds.

Implements TagLib::AudioProperties.

int TagLib::Ogg::Opus::Properties::opusVersion ( ) const

Returns the Opus version, currently "0" (as specified by the spec).

virtual int TagLib::Ogg::Opus::Properties::sampleRate ( ) const

Returns the sample rate in Hz.

Implements TagLib::AudioProperties.
