Key Features

Monitor & Meters

Dynamic Tracking, Instant Anomaly Detection

Continuous waveform monitoring and FFT spectrum analysis enable real-time identification of signal anomalies such as clipping, clock jitter, and more. Simultaneously track critical meters including RMS Level, THD, SND, and frequency response. Supports configurable high-pass/low-pass filters and A/C/Z frequency weighting.

Continuous Sweep Analysis

Full-Range Rapid Measurement

Utilizing logarithmically varying sweep signals, this function extends energy accumulation time in low-frequency ranges to ensure measurement accuracy while significantly improving test efficiency. It enables fast and reliable testing for applications such as resonance peak detection in speakers, phase continuity analysis in headphones, and frequency response flatness evaluation in amplifiers. The results automatically comply with industry standards, generating professional test reports. An indispensable tool for audio R&D, production, and quality control.

Sound Power Testing

Precise Quantification of Acoustic Performance

This solution supports sound pressure-based sound power measurement, fully compliant with international standards ISO 3744 (Engineering Method), ISO 3745 (Precision Method), and ISO 3746 (Survey Method), meeting diverse testing accuracy requirements across different scenarios. Widely applied in R&D testing and quality control across consumer electronics, automotive audio systems, and professional audio equipment.

AI-Powered Full-Process Detection for Electroacoustic Abnormal Sounds

Detection for Electroacoustic Abnormal Sounds

This cutting-edge AI technology eliminates manual labeling by analyzing acoustic fingerprints through deep learning, rapidly identifying deviations from normal sound patterns.The system delivers real-time diagnosis within seconds and continuously improves through adaptive learning. Its proprietary Acoustic DNA technology enables not only instant anomaly detection but also predictive fault alerts, providing intelligent support for equipment health management and predictive maintenance.
