US 2026/0213720 A1 · TECHNIQUES FOR AUTOMATIC EQUALIZATION OF AUDIO

Abstract

In various embodiments, the disclosed techniques automatically change the audio equalization levels of audio content. When an audio content is requested for playback, the equalization manager of an audio system extracts the frequency components of a segment of the audio content. The equalization manager analyzes the frequency components of the segment and separates the frequency components into predefined frequency bands based on the analysis. The equalization manager determines sound pressure level (SPL) metrics of each frequency component. The equalization manager generates a custom equalization setting using gains calculated for each frequency band based on the SPL metrics. The equalization manager then adjusts the audio segment by applying the custom equalization setting to generate a modified segment (e.g., applying the calculated gains to each of the frequency bands). The modified segment is then output as audio to a user. The process then repeats for additional segments of the audio.

receiving audio content for playback;
extracting a plurality of frequency components from a first segment of the audio content;
separating the plurality of frequency components into a plurality of first frequency bands;
determining a sound pressure level (SPL) for each frequency component in the plurality of frequency components;
determining, based on the SPL of each frequency component in the plurality of frequency components, a gain for each frequency band in the plurality of first frequency bands;
generating, based on the gain for each frequency band in the plurality of first frequency bands, a first equalization setting;
adjusting, based on the first equalization setting, the first segment to generate a modified segment;
and
outputting the modified segment using one or more speakers.
