Lovelace's Square
Interactive GUI for baseline correction using Asymmetric Least Squares Smoothing (Eilers & Boelens, 2005).
Supports batch and signal-by-signal correction with real-time preview, configurable smoothness (lambda) and asymmetry (p) parameters, zoom and dark mode, and export of corrected data.
Designed for spectroscopic preprocessing in chemometrics workflows.
