- 基于5416芯片，通过按键控制，实现对音频信号进行高通，低通，带通滤波。并有led显示-Based on 5416 chip, through the control buttons, the audio signal to achieve high-pass, low pass, band pass filter. And has led displays
AVRGCC7_SPWM_D
- AVR 单片机制作的D类功放，用AVR 自带的AD采样音频输入，产生调制的PWM波，驱动功率H桥，然后滤波成放大的具有驱动能力的音频信号，驱动喇叭播放音乐。完全用程序实现，里面存有正弦波的数据，也可以输出正弦波。-AVR microcontroller produced by the Class D amplifier, the AVR AD sampling the audio input, to generate the modulation of PWM wave-driven power

- 利用单片机定时器产生高低电位各0.5毫秒的方波，该方波再经二阶滤波变成1K赫兹的正弦波，即为音频信号-To produce high and low potential of each 0.5 ms using SCM timer Fang Bo, the square wave and then by two order filter into 1K Hz sine wave, namely for audio signal
基于DSP中断工作方法的音频滤波代码
- 设计基于DSP中断工作方式的语音采集-滤波-回放系统，要求： 1.输入为双声道立体声音频，用48kHz的采样率采集音频。 2.将音频信号经36阶截止频率10kHz的低通滤波处理后，再进行回放。 3.要求采用音频接收、播放双中断工作方法。
