An audio filter for the 21st Century

VIR Filter technology represents a fundamental breakthrough in digital audio filtering. By rethinking filter architecture from the ground up, we've achieved performance that surpasses both FIR and IIR filters while using a fraction of the computational resources.

  • 75% reduction in MIPS compared to FIR
  • Near-zero latency for real-time applications
  • Minimum phase response preserves transients
  • Superior low frequency resolution
  • Smooth, natural frequency response
  • Ideal for resource-constrained devices

What is APVD?

Acoustic Power Volume Density is Eilex's proprietary measurement methodology that captures how a speaker system actually performs in real-world conditions—not just in an anechoic chamber.

Traditional frequency response measurements are highly dependent on microphone position and room acoustics. APVD uses multiple measurement points and sophisticated averaging to extract the true acoustic output of the system, independent of the measurement environment.

This means PRISM corrections translate accurately from the lab to the living room, the car cabin, or wherever your product will be used.

APVD represents a paradigm shift in how we measure and optimize audio systems — focusing on what listeners actually hear, not just what we can measure in ideal conditions.
