FlexCurve is a VST3 headphone-correction curve editor, layer-based calibration tool, AutoEQ workspace, and FIR renderer. It imports local TXT, CSV, Equalizer APO / Wavelet GraphicEQ, APO Parametric EQ, Melda FreeForm EQ CSV, and WAV FIR files as editable layers, previews changes in real time, blends active layers into an Average curve, and renders the result as Minimum, Natural, or Linear phase FIR.
