DSP Sound Shifter

PITCH & CHARACTER

Transform pitch, formants, distortion, and spatial effects via Mic recording or Audio Upload.

DSP Transformation Principles

1. Pitch & Speed Ratio:

Frequency transposition is calculated via ratio: $f_{new} = f_0 \cdot 2^{(\Delta ext{semitones} / 12)}$.

2. Biquad Filtering:

2nd-order IIR biquad filters shape formants and timbre with variable resonance $Q$.
