Audio Pitch Shifting Using the Constant-Q Transform
| Publication ID | 34594 |
| Abstract | In this paper a frequency-domain pitch shifting approach based on the CQT is proposed. The CQT is specifically attractive for pitch shifting because it can be implemented by frequency translation (shifting partials along the frequency axis) as opposed to spectral stretching in the Fourier transform domain. Furthermore, the high time resolution of CQT at high frequencies improves transient preservation. Audio examples are provided to illustrate the results achieved with the proposed method. |
