VIR Filter is a variable resolution, high precision equalizer and simply the most powerful method available for achieving an arbitrary frequency response. It offers incredible accuracy and far more eﬃcient implementations than alternative EQ technologies.
VIR achieves this with selectable frequency resolution, which dramatically outperforms high-order FIR equalizers, particularly in low-frequency correction. VIR also provides more precision than traditional parametric equalizers and achieves a detailed response using a fraction of the computations.
VIR Designer software is used to measure acoustic power and create a correction VIR EQ.
VIR Designer automates the measurement and EQ synthesis process. With either single-point or multi-point measurements, VIR Designer measures any space or speaker. VIR Designer can be integrated into a product to create a complete auto EQ solution. VIR EQ synthesis is non-iterative so creating a new VIR EQ is fast and deterministic.
The composite of many measurements performed by VIR Designer take into account directivity patterns and room reflections and modes at multiple listening positions. This ensures a more accurate EQ, correcting the response the listener will actually hear.
The generated correction EQ can be adjusted with a target curve which enables you to craft your own custom sound. VIR EQ synthesis is quick which enables real-time EQ adjustment and audition.
