The pitch shifter allows you to change the pitch without changing the playback speed using FFT.
Item | Description | Initial Value | Lower Limit | Upper Limit |
---|---|---|---|---|
Pitch Shift | Specifies the amount of pitch variation. (The recommended range for a good sound quality is -300 to 300 cents) | 700 cent | -2400 cent | 2400 cent |
Pitch Shift Mode | Specifies the pitch shifting mode: Music Vocal (enables formant) Effect (emphasizes localization) Speech (enables formant, emphasizes localization) | Music | - | - |
Formant Shift | Specifies the amount of formant shifting. This value is used when the Pitch Shift mode is "Vocal" or "Speech". | 0 | -2400 cent | 2400 cent |
Window Width | Specifies the size of the blocks processed by the FFT (i.e. the length of the analysis window). Larger values increase the spectral accuracy but make the sound less sensitive to quick changes. | 1024 | 128 | 2048 |
Overlap | Specifies how the FFT analysis window slides over the signal. If the next analysis window overlaps a lot with the current one (i.e. if the overlap parameter is high), the quality is higher but the load increases. | 4 | 1 | 8 |
