An audio signal adaptive equalization method, system, device and storage medium

Abstract

This application discloses an adaptive equalization method, system, device, and storage medium for audio signals. The technical solution provided in this application involves determining the exponential moving average curve of the audio signal, and then determining a first equalization curve based on the exponential moving average curve and preset reference information. Next, it determines the difference curve between the exponential moving average curve and the short-time spectrum of the audio signal, calculates a correction curve based on the difference curve, and corrects the first equalization curve based on the correction curve to obtain a second equalization curve. Finally, it determines the equalization parameters of the audio signal based on the second equalization curve, and performs equalization processing on the audio signal based on the equalization parameters. By employing the above technical means, the inaccuracy of equalization parameters caused by the difference between the exponential moving average curve and the audio signal can be avoided, improving the accuracy of audio signal equalization processing and thus enhancing the user's listening experience.
