Golang Implementing WAV files to MP3 files

This is a creation in Article, where the information may have evolved or changed.

Instead of Golang a built-in library for WAV-MP3, this article transforms it by Golang calling the lame command of Linux.

In a Linux environment, lame is not installed by default, so you first need to install lame (personal save download file: Http://pan.baidu.com/s/1qWp71G4#path=%252Fsharesoft%252Flinux%252Flame).

Linux lame Installation and use:
1. Unzip lame compressed file: TAR-VZXF lame-3.98.4.tar.gz
2. Go to the extracted files directory, then execute: "./configure--enable-shared", "make", "Make Install"
3. How to use lame: lame xxx.wav xxx.mp3 (so you can convert xxx.wav files to Xxx.mp3 files)

The next step is to invoke the Linux Lame command via Golang to implement the WAV mp3.
