Description: 功能如下
使用STM32F103ZE芯片，通过DM9000AEP把互联网上的网络音频流（支持shoutcast、http mp3流）抓取下来，先在板子上外扩的SRAM上缓存。然后在STM32F103ZE上通过mp3软件解码器解码变成PCM音频，通过DMA方式送到PCM1770进行回放；
它也可以流畅播放SD卡上的mp3、wav格式文件。（支持大于4G的SD卡）；
通过3.2寸240*320的TFT触摸屏、五向按键、红外遥控器进行控制；
红外遥控器具备自学习功能；
系统信息显示；
LCD背光、音量可调，触摸灵敏度可随时校准；(Functions are as follows
The use of STM32F103ZE chip, through the DM9000AEP to the Internet network audio stream (Shoutcast, HTTP MP3) to crawl down, the cache in the outer SRAM expansion board. Then, on STM32F103ZE, the MP3 software decoder decodes it into PCM audio and sends it to the PCM1770 for playback via DMA;
It also allows you to play MP3 and WAV files on the SD card smoothly. (support SD card larger than 4G);
Through the 3.2 inch 240*320 TFT touch screen, five button, infrared remote control;
Infrared remote controller has self-learning function;
System information display;
LCD backlight, adjustable volume, touch sensitivity can be adjusted at any time;)

Description: 音频混合：实时录制audio时录制麦克风数据 和 写入背景音乐
本次案例实现了
＊MediaPlayer 播放音频
＊AudioTrack 播放音频 mp3 --> pcm data ( libs/jl1.0.1.jar )
＊AudioRecord 录制音频 pcm file
＊AudioTrack 播放音频 pcm data
＊AudioRecord 录制音频 use MediaCodec & MediaMuxer write data
＊MediaExtractor 和 MediaCodec 手动解码出 pcm 数据
＊混合音频(Audio mixing: recording microphone data and writing background music when recording audio in real time
This case has come true
* MediaPlayer broadcasts audio
* AudioTrack MP3 - > PCM data audio (libs/jl1.0.1.jar)
* AudioRecord recording audio PCM file
* AudioTrack broadcasts audio PCM data
* AudioRecord recording audio use MediaCodec & MediaMuxer write data
* MediaExtractor and MediaCodec manually decode the PCM data
Mix audio)
