How Cubic Spline Peak Restoration Works

Digital clipping occurs when an audio signal exceeds 0 dBFS (100% digital ceiling), causing the tops and bottoms of the sound wave to be sheared off into flat, harsh square waves. This generates sharp odd-order harmonic distortion that ruins vocal warmth and punchy transients.

Our De-Clipper Engine uses mathematical Cubic Hermite Spline Interpolation:

Boundary Trajectory Analysis: Reads unclipped slope angles immediately before and after flat plateaus.
Continuous Derivative Spline Fitting: Generates continuous third-order polynomial arcs across truncated samples.
Dynamic Headroom Re-scaling: Scales the master audio by up to -6.0dB to accommodate newly restored transient peaks without digital clipping.
