Light control method, device and equipment and storage medium

Abstract

The invention discloses a light control method, device and equipment and a storage medium. The method comprises the steps of: reading corresponding sampling data in a fixed period which is not higher than a note value from a currently played audio file; calculating an amplitude-frequency diagram according to the sampling data, and determining the frequency and the amplitude of the maximum amplitude-frequency component; searching in a pre-formulated musical scale-RGB mapping table to obtain matched RGB three primary colors according to the frequency and the amplitude of the maximum amplitude-frequency component; and according to the obtained RGB three primary colors, driving RGB-LED light mixing and color matching through PWM (Pulse Width Modulation). Therefore, the scheduling period of a algorithm can be determined conveniently, multiple music segments do not need to be acquired in advance, and limitation of music types and the number of the music segments is avoided; and meanwhile, the musical scale-RGB mapping table is matched with RGB three primary colors by comprehensively applying two pieces of information, namely the frequency and the amplitude of the maximum amplitude component, and color matching changes of the same note under the condition of different loudness are enriched.

AI Technical Summary

Benefits of technology

The technology described in this patented describes how it helps manage musical recordings with varying levels or frequencies based upon their importance during performance. It uses various techniques like sound detection (detects specific sounds) and adjustments made automatically overtime if necessary. This allows users to customize the settings they want while recording them. Overall, these technologies help improve the quality of recorded songs even better.

Problems solved by technology

Technically speaking, this patented technology allows users to match different colored sounds with their own musical accompaniment or create customized displays that use specific types of visual media like images or videos instead of predefined arrangements. However, current techniques have limitations such as slow response times due to changes made during playback caused by external factors like background noise from sunlight hitting windows at nights. Additionally, these systems only work well when multiple devices can be connected together without interferring each others' movements.
