This Spectral Processing Workstation lets you craft evolving, non-linear filter shapes and movements impossible to achieve with analogue EQs. Multi-Curve Spectral Filtering MagicFilter is a multi-curve spectral filter and EQ workstation designed for detailed, creative frequency shaping. Apply independent filter amounts per frequency or frequency range, then mix, modulate, and spread your curves to create anything from subtle, organic movement to extreme spectral transformations. Beyond Conventional EQ Unlike analogue or traditional digital EQs, MagicFilter operates in the frequency domain, enabling filter curves and dynamics that would be impossible with hardware. Design non-linear, highly customized shapes and introduce dynamic movement through modulation. Morph seamlessly between four different filter curves, and use the Curve Modifier to shift, invert, or skew them — even in stereo — for precise and flexible control over spectral motion. Global Controls & Fine Shaping Quickly adjust cut and boost amounts to refine your overall curve, and use the built-in lowpass and highpass filters to set the tonal boundaries of your sound. Fine-tune the balance using wet gain and dry/wet control, enabling anything from subtle enhancement to bold, transformative filtering. These controls ensure fast, intuitive workflow while offering deep flexibility. MagicFilter 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). More information here: https://gs-dsp.com/products
