摘要
通过对音响设备输出端子输出信号的音乐节奏进行识别和自适应数据采集,利用嵌入式单片机系统实现对音乐节奏识别灯效系统的智能同步控制,使灯光随音乐的节奏变化而变化,从而实现两者的完美配合。同时,在设计中对系统的延时性能及可行性进行了具体的分析和讨论。
By identifying the rhythm of the signal which is outputted by the sound equipment, and by gathering the auto adaptive data, with embedded PC system, we can have the music rhythm identifying lamp system controlled intelligently, then the light of the lamp can be changed with the musical rhythm. So they can cooperate perfectly. In the same time, the delay and feasibility performance of the system in the design are analyzed.
