SplineEQ Description

SplineEQ is a linear phase equalizer plugin. Designed to be simple and flexible, SplineEQ allows you to create filters using Bézier splines, the best known way to design curves. Offers a better sound quality than the more common minimum phase equalizers by not affecting the phase of sound, only the intensity of frequencies, which makes it easier to achieve good sounding results. In addition, it comes with the benefit of not inserting aliasing artifacts. Main features: Spline-based filter design: Filters are simply created by designing a spline curve which can be made to adopt any imaginable shape. No filter types to choose from, all points simply define part of the shape of the filter's spline curve. The actual filter's frequency profile is displayed as a dashed curve when it differs from the ideal spline curve (this can be changed by changing the filter's resolution). Up to 60 bands or as low as 1: You can create or disable bands by double clicking on the visualisation area of the interface and adjust them either in that area or using the knobs or even the automatable parameter sliders in the host's interface. Simple curve modification functions: You can modify the curve as a whole using the transpose function to shift the curve up and down by up to 10 octaves, affect the overall gain to shift all gain settings up or down evenly or even change the gain scale to apply a ratio to all gains, thus enabling you to either flatten, exaggerate or reverse the shape of a curve. Frequency analyser: More intuitive than your usual logarithmic curve frequency display, this frequency analyser shows you the intensity of frequencies before and after the filtering with colours. It's also fine tuned so that intensities at different frequencies are represented in a way that matches closely to our perception. It moves in a fluid manner in sync with the source sound and has a frequency resolution of about 10 Hz. Smooth and fluid graphics: The whole interface responds fluidly to change, even the frequency visualisation has a great frame rate and all the graphics are perfectly anti-aliased. -Infinite dB to +60 dB gain range: This allows you to completely silence entire ranges of the spectrum or to really bring back some fainter harmonics by boosting their amplitude thousandfold. Gains are represented logarithmically between -60 dB and +60 dB and linearly below -60 dB. Given the uniquely immense gain range there's also a built-in limiter whose knob lights up when over the adjustable threshold. Smooth transitions: Changing parameters, either by adjusting the knobs, the graph or by parameter automation is always done smoothly and creates no audio artifacts.
