Member Function Documentation

Evoral::Beats ARDOUR::BeatsFramesConverter::from ( framepos_t  frames ) const

virtual

Takes a duration in frames and considers it as a distance from the origin supplied to the constructor. Returns the equivalent number of beats, taking tempo changes into account.

Implements Evoral::TimeConverter< Evoral::Beats, framepos_t >.

Definition at line 49 of file beats_frames_converter.cc.

framepos_t ARDOUR::BeatsFramesConverter::to ( Evoral::Beats  beats ) const

virtual

Takes a positive duration in beats and considers it as a distance from the origin supplied to the constructor. Returns the equivalent number of frames, taking tempo changes into account.

Implements Evoral::TimeConverter< Evoral::Beats, framepos_t >.
