Revolutionary In-Car Audio Spatial Sound Field Correction Solution
SmartEQ is a revolutionary in-car audio spatial sound field correction system. Through advanced adaptive algorithms, it intelligently analyzes and optimizes the in-car sound field distribution, allowing you to enjoy perfect audio experience from any position in the vehicle.
Even with high-quality automotive acoustic equipment, sound can still be distorted by unnecessary reflections, resonances, and delays due to the complex shape, size, surface materials, and internal modifications of the car cabin. SmartEQ, as an advanced adaptive tuning system, optimizes the sound field of the entire car space through intelligent and simple methods. The system uses precise sound field measurement technology, combined with patented multi-position sound field calculation algorithms, to achieve customized system output, quickly correct speaker performance, and effectively overcome acoustic challenges. Whether you're listening from any position in the car, you can enjoy balanced and accurate sound effects.
SmartEQ uses objective measurement and correction methods, with results showing high repeatability and consistency. No professional tuner required - anyone can achieve accurate and excellent audio tuning.
Only requires a single microphone for measurements at multiple positions in the car, with no special tools needed. The entire correction process takes just minutes to achieve accurate audio optimization.
Uses optimized algorithm design, requiring only low CPU computing power to complete processing, offering significant cost advantages and wide application across various devices.
APDSM (Acoustic Power Density Smart Measurement) technology is the core technology of SmartEQ. Through this technology, SmartEQ can precisely measure the frequency response of the in-car sound field and make precise adjustments using SmartEQ Filter technology, achieving perfect correction of the in-car sound field. APDSM technology solves the problem of inconsistent volume from single or multiple driver units by measuring sound wave interference in the space in front of the speakers. It can simultaneously optimize frequency response, time, and phase, making the sound closer to the original material. More importantly, APDSM technology can provide objective and true test results, almost unaffected by operator and environmental factors, greatly reducing acoustic design constraints for industrial and structural designers and significantly shortening development cycles.
SmartEQ Measure is a professional sound field measurement software equipped with APDSM technology, supporting mainstream desktop operating systems including Windows, Mac, and Linux, as well as Android and iOS mobile platforms. The software features a clean and intuitive interface with clear operation procedures, enabling quick completion of sound field measurement and correction work.
SmartEQ Filter is an innovative hybrid filter used to execute APDSM adjustments, cleverly combining the advantages of IIR and FIR filters. As a minimum-phase filter, it effectively avoids phase distortion, significantly reduces signal delay, and ensures precise speaker output signals. With the same filter resolution, SmartEQ Filter has lower computing power consumption, not only reducing system costs but also supporting various processor platforms, including DSP, CPU, MCU, and SoC. Meanwhile, it maintains extremely high precision, capable of precisely fitting various complex target curves. As shown in the figure below.
