Supports 1/3 octave and 1/1 octave analysis settings, provides finer frequency resolution selection, adapts to different acoustic analysis needs, and ensures more accurate spectrum analysis results.

Accurately calculates sound pressure level (SPL) and provides real-time sound pressure level change curve to help users monitor changes in the sound environment.

Supports time-frequency analysis (Time-Frequency Analysis), such as short-time Fourier transform (STFT) and wavelet transform (Wavelet Transform), which can intuitively display the distribution of sound signals in time and frequency.

The acoustic analyzer supports the calculation of psychoacoustic characteristics, including loudness, sharpness, roughness and other indicators. These characteristics are used to evaluate the subjective perceptual properties of sound, helping users more fully understand the impact and perceived quality of sound.

Filtering is used to remove unwanted noise or interference from a signal, retaining the frequency components of interest. It can be performed through low-pass, high-pass, band-pass or band-stop filters, etc., and is widely used in signal processing, noise control, vibration analysis and other fields to improve the quality and accuracy of signals.

The acoustic analyzer also supports Order Analysis, a technology specifically used to analyze vibration signals of rotating machinery equipment. Through order analysis, the vibration frequency components of mechanical equipment at different rotational speeds can be identified, helping users quickly locate and diagnose possible equipment faults.

The acoustic analyzer is available in 4-channel and 8-channel configurations, supports simultaneous collection of multi-channel audio signals, and is suitable for multi-point monitoring and analysis of complex sound fields. This multi-channel configuration is ideal for precise acoustic studies in complex sound field environments, such as sound source localization and sound field reconstruction.
