Pitch shifter based on complex dynamic representation rescaling and direct digital synthesis |
|---|
| E. HERMANOWICZ and M. ROJEWSKI |
| In this paper a new pitch shifter using a complex instantaneous frequency rescaler and direct digital synthesizer is presented aimed at an application in a handset calling signal composer. The pitch shifter introduced here exhibits an excellent performance as a generator of different melodies, where the sound of each note in a melody, e.g., imitating a popular hit, is derived from a short recording of a voice of a chosen creature via complex dynamic representation processing. |
