这是一个完整的利用FFT对音频进行分频的工程包,是基于带ADC的51系列单片机进行的,可用KEIL51编译器进行编译.可不作任何改动就可直接烧入单片机内进行运行.-This is a complete use of FFT on the audio frequency of the engineering package, is based on the 51 Series MCU with ADC carried out, available KEIL51 compiler to compile. From time to make any changes can be directly burned into the microcontroller to run within.
