Description: 直接压缩成mp3的录音机程序，录音过程中不需要产生.wav文件，边录音边压缩，处理速度快，节约磁盘空间，尤其对长时间录音非常合理。本程序可以录制单声道、立体声、左声道、右声道的语音。录音和播放过程中都有实时的波形显示。特别感谢我的好朋友李志刚的指点，由于他的提醒，我从使用mciSendXXX()改用waveInXXX()。-directly into compressed MP3 recorders procedures, the process of recording have not. Wav file, while recording edge compression, fast processing speed and save disk space, especially for long recording very reasonable. This procedure can record mono, stereo, left channel, right channel voice. Recording and playback process have real-time waveform display. Special thanks to my good friend, Li Zhigang's instructions, he reminded, I use mciSendXXX () switch waveInXXX ().

Description: LAME无疑是目前最优秀的MP3编码软件，与传统的MP3编码器相比，它能够更好地利用人耳遮蔽效应，并且支持VBR（可变码率）以及joint stero（联合立体声）技术，从而在一定的压缩比达到了更好的听音效果。所以，使用LAME编码的MP3具有细节丰富、高频失真小的优点。这是最新发布的4.0 Alpha版本，编码速度有了非常大的改善，但是音质效果却并没有提高的迹象。推荐使用VBR-0方式编码。

Description: The Arduino MP3 Shield has an onboard 3W Class-D stereo audio amplifier which could drive 4ohm load such as loudspeaker.
The Arduino MP3 Shield has seven buttons and a UART interface, that is to say user has two ways to control the module flexibly. The UART interface is connected to the Arduino hardware UART by default. Since most Arduino boards have only one UART interface, this module’s UART interface can be redefined to Arduino D7 (TX) and D8 (RX) through the jumpers on board. With SoftSerial lib, Arduino could also send data to this module.
We tested with 8G SDHC card and 16G U-disk. It works in perfect compatibility. We haven’t tested larger SD and U-disk yet.
