摘要:
Playback of a graphical representation of a digital musical score is synchronized with an expressive audio rendering of the score that contains tempo and dynamics beyond those specified in the score. The method involves determining a set of offsets for occurrences of score events in the audio rendering by comparing and temporally aligning audio waveforms of successive subclips of the audio rendering with corresponding audio waveforms of successive subclips of an audio rendering synthesized directly from the score. Tempos and dynamics of human performances may be extracted and used to generate expressive renderings synthesized from the corresponding digital score. This enables parties who wish to distribute or share music scores, such as composers and publishers, to allow prospective licensors to evaluate the score by listening to an expressive musical recording instead of a mechanically synthesized rendering.
