Eilex PRISM® is an extremely precise, highly efficient EQ solution that can get your product sounding its best in minutes. Eilex PRISM’s measurement process can be done in minutes by a single person without a specialized setup.
Eilex PRISM Composer software makes the tuning process fast and intuitive, with real-time results and an easy-to-use GUI.
- Acoustic Power Volume Density (APVD) Frequency Response: Eilex PRISM uniquely measures and equalizes APVD frequency response, which is the most accurate mathematical representation of sound as heard by the human ear.
- Time and Phase Alignment Correction: PRISM automatically corrects time and phase alignment errors, particularly in the low-frequency range, enhancing the sound’s fidelity and clarity.
- VIR Filter® Technology: The system uses a Variable-resolution Impulse Response (VIR) filter for equalization, superior to traditional FIR filters, especially at low frequencies. The VIR filter requires less computational resources and provides consistent resolution across the entire audio spectrum.
- Automated Measurement Process: PRISM’s measurement is automated, utilizing a single microphone and the PRISM Composer software. The software analyzes data from an unlimited number of points in 16,384 frequency bands to build an equalization curve.
- Versatile Applications: Eilex PRISM can be used to equalize anything that makes sound, making it suitable for everything: high-end audio, TVs, portable audio devices, wireless earbuds, car audio, and even subwoofers.
- Flexibility and Time Efficiency for Designers: Eilex PRISM offers flexibility to product designers. Whatever the speaker layout or acoustic properties of a product, Eilex PRISM can handle equalization.
- Application on Microphones: Besides speakers, PRISM can correct irregular frequency responses in microphones, especially MEMS microphones.
