#### 前言

本demo是使用开源项目lame来将PCM数据编码成MP3数据。（环境：x86_64 Ubuntu16.04 64位）



### 1、编译使用

**lame的编译：**(源码下载地址：[https://sourceforge.net/projects/lame/files/lame/](https://sourceforge.net/projects/lame/files/lame/))

```bash
tar xzf lame-3.100.tar.gz
cd lame-3.100/
./configure --prefix=$PWD/_install
make
make install
```

**本demo的编译与使用：**

```bash
$ make clean && make
$ 
$ ./pcm2mp3
Usage: 
    ./pcm2mp3 <in pcm file> <smaplerate> <channels> <out mp3 file>
Examples: 
    ./pcm2mp3 audio/test1_44100_16bit_stereo.pcm 44100 2 out1_44100_stereo.mp3
    ./pcm2mp3 audio/test2_22050_16bit_stereo.pcm 22050 2 out2_22050_stereo.mp3
    ./pcm2mp3 audio/test3_22050_16bit_mono.pcm   22050 1 out3_22050_mono.mp3
    ./pcm2mp3 audio/test4_8000_16bit_mono.pcm     8000 1 out4_8000_mono.mp3
```
