Photosounder proudly presents SplineEQ, 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.

Features:

Linear phase equalizer. 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. Also has the advantage of not incurring aliasing artifacts.
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.
Up to 60 bands (only up to 4 in the free version of SplineEQ) 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.
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.
Smooth transitions. Changing parameters, either by adjusting the knobs, the graph or by parameter automation is always done smoothly and creates no audio artifacts.
Adjustable resolution, latency and CPU usage. The resolution of the filter can be lowered or increased (up to roughly 22 Hz) and the processing latency can be changed to obtain a lower CPU usage or a lower latency.
Good performance. Linear phase equalizers always require more power than other types of equalizers. However SplineEQ is as fast or faster than other linear phase equalizers, often with less latency.
Also supports all sampling rates (384 kHz included), is available on both Windows and Mac, in VST (2.4) and AU format, in 32 and 64 bits. All input, output and processing are done in 64-bit floating point format and in stereo.
