Transform harmonics and frequencies independently with this multi-curve spectral pitch and frequency shifter. Multi-Curve Spectral Pitching MagicPitch is a multi-curve spectral pitch and frequency shifter designed for detailed control of harmonic and inharmonic motion. Apply independent pitch or frequency shifts per frequency or frequency range to de-tune harmonics, reshape drum transients, or craft otherworldly vocal textures. Pitch vs Frequency Shifting Pitch Shifting scales all frequencies by a common factor, preserving harmonic relationships for musically coherent transpositions. Frequency Shifting adds a fixed frequency amount to all components, changing their harmonic structure for more experimental or inharmonic results. MagicPitch can operate in either mode — or combine both at once — giving you precise control over how harmonic or unstructured the outcome becomes. Detailed Spectral Control Use the Curve Editor to shape thousands of pitch and frequency shifters simultaneously, allowing detailed sculpting across the entire spectrum. Global parameters such as Pitch Offset, Frequency Offset, Balance, and FX Amount provide quick, broad adjustments. MagicPitch is an AUv3 audio effect plugin compatible with Logic Pro, AUM, Cubasis, GarageBand and many more. A Desktop version is also available for Windows and macOS (VST3 / AU / AAX).
