Abstract:
Systems, methods, and apparatus for pitch trajectory analysis are described. Such techniques may be used to remove vocals and/or vibrato from an audio mixture signal. For example, such a technique may be used to pre-process the signal before an operation to decompose the mixture signal into individual instrument components.
