Abstract

Most of audio players on the market use the hardware filter or DSP chip to process spectrum, the use of the techniques on the one hand requires high hardware costs, on the other hand, software and hardware implementations is more complex. In order to overcome the shortcomings, a spectrum display using fast Fu Liye transform (FFT) algorithm is designed. The audio file in SD card is decoded through STC12C5A60S2 microcontroller, and the FFT algorithm is used to sample, quantify and divide the audio signal through A/D internal microcontroller, the results being processed is sent to the LED dot matrix display screen, in addition, the system is introduced into the sensor, and the automatic adjustment of the display brightness is realized. This template explains and demonstrates how to prepare your camera-ready paper for Trans Tech Publications. The best is to read these instructions and follow the outline of this text.
