AI Technical Summary

Technical Problem

Existing room acoustic calibration systems are difficult to adapt to listening environments with different acoustic characteristics, resulting in poor listening experience. Users find it difficult to understand the complex correspondence between frequency response curves and subjective listening experience, and the automatic calibration capability is insufficient, failing to provide a personalized listening experience.

Method used

By acquiring impulse response data of the room, dividing the frequency bands to calculate reverberation time, extracting mid-frequency reverberation characteristic values, determining the total high-frequency roll-off, and combining user low-frequency preference parameters, constructing low-frequency, mid-frequency transition, and high-frequency region curve segments, generating continuous target curves, and adaptively generating audio calibration curves.

Benefits of technology

It enables the adaptive generation of suitable audio calibration curves based on the room's acoustic characteristics, improving the listening adaptability and user experience of the audio system and ensuring that the calibration effect is intelligently adapted to the room's acoustic characteristics.
