ABSTRACT:
The invention is directed to a method and apparatus for evaluating and correcting rhythm of audio data. Embodiments of the invention are capable of obtaining preferred rhythm in audio data, and strategically correcting the portions of audio data resulting an enhancing rhythm. A system embodying the invention may detect each transient in audio data, compute an ideal time for the transient and determine the time deviation from the expected ideal time. The system may correct for the time of the transient by altering the audio data before or after the transient. The system utilizes one or more methods to correct for the timing while preserving the audio quality of the signal.
