What SplineEQ does
Rather than stacking fixed bands, SplineEQ builds each filter from a spline curve that the user designs directly on the graph. The developer describes the linear phase design as better sounding than the more common minimum phase equalizers, and the plugin offers up to 60 bands. The curve can be modified as a whole with a transpose function, and a frequency analyser is shown on a scale the developer describes as easier to read than the usual logarithmic display. The interface responds fluidly to changes, the gain range reaches +60 dB and extends to complete silence, and the resolution filter can be lowered or raised to trade latency and CPU usage against accuracy.
Key features
- Spline-based filter design. Filters are created by designing a spline curve across the frequency range, so the shape is set by drawing rather than by choosing fixed band types.
- Curve modification. The curve can be modified as a whole with a transpose function instead of moving each point separately.
- Frequency analyser. The analyser uses a frequency display that the developer describes as easier to read than a usual logarithmic curve.
- Gain range. The gain range runs up to +60 dB and can be pulled down to completely silence a part of the spectrum.
- Resolution and latency. The resolution filter can be lowered or raised, and the developer notes that a higher setting increases latency and CPU usage.
Compatibility
SplineEQ comes as VST3, AU and CLAP for Windows and macOS (64-bit), with native support for Apple Silicon listed and a minimum of macOS 10.12.
