Luftikus is a digital equalizer that faithfully recreates the character of an analog EQ with fixed half-octave bands and an additional high-frequency boost. It offers a unique approach by allowing deeper cuts than the original hardware and includes a keep-gain mode that maintains the overall gain level during adjustments, preventing unwanted volume shifts. This balance between vintage tonal quality and modern flexibility makes it suitable for detailed sound shaping in mixing and mastering.

The EQ features hardware-modeled bands at 10, 40, 160, and 640 Hz, along with a 2.5 kHz shelf and an optional boost-only shelf that can be set at 2.5, 5, 10, 20, or 40 kHz. It supports both mastering and analog modes, and includes an output trim for precise gain control. These features provide a broad palette for enhancing clarity and presence in audio tracks, while the improved design ensures deeper cuts without compromising sound quality.

Built on the JUCE framework, Luftikus is open-source under the MIT license, encouraging transparency and ongoing development. Continuous updates have refined its performance, including new GUI designs, VST3 support, and multi-channel capabilities such as 5.1 surround sound. Whether for professional studio use or home production, Luftikus delivers a polished, analog-inspired EQ experience with modern enhancements.
