Microphone Array Solutions
Microphone Array Solutions for Acoustic Evaluation and Tuning
Mic array based workflows support rapid product development, through high quality, repeatable and reproducible acoustic measurements. Spend more time developing and improving your product, and less time in the lab collecting data. The right microphone array and workflow can ensure measurements better match perception.
Automotive Six Microphone Array
Easy to Setup – Ready to Travel
Engineered for an efficient workflow, and portability: Aurio Acoustics Six Microphone array follows AES Technical Committee on Automotive Audio (AES-TCAA) spacing and orientation. MEMs based microphone (with built-in response correction) is extremely consistent and robust.
Developed to make automotive audio system evaluation and tuning easy
MEMs based microphones are inherently well matched in sensitivity, reducing “calibration burden” – typically matching within 0.5dB, with more omni-directional behavior than 1/4″ microphones. Designed to help engineers spend less time in setup and calibration, and more time evaluating and tuning. Our robust case keeps mics, array and calibrator adapter organized and ready to travel. Aurio Acoustics mics can easily fit in a backpack with stand and cable for engineers that travel to evaluate or tune audio systems.

In-Room Arrays
Simple Solutions for Complex Acoustics
Professional studios and serious hi-fi enthusiasts need Reference Quality reproduction for producing and enjoying music. Developers of TVs, Sound-bars, and Smart speakers need to evaluate “customer facing” sound-quality for development and tuning. Aurio Acoustics In-Room Arrays are designed for highly repeatable and reproducible measurements, that correlate with lab or anechoic measurements in a listening room (or desk) setting.
Developed for In-room evaluations
- TVs, Sound-bars, Smart-Speakers and other audio products designed to be part of our environment have complex acoustics – often inseparable from their setting. In-room evaluations take into account “adjacent boundaries” as well as the unique combination of Direct Sound, Early Reflections and Total Radiation from these products in making critical evaluation and tuning choices key in delivering best in class consumer audio products.
- Tune studio or hi-fi systems for the room – optimizing timbre, level and delay of each source, and bass management for consistent bass throughout the listening space.
- Evaluate Laptops, Tablets, or other “single listener” systems in-situ
