Mac Compression mp3 audio file/linux applicable

In order to compress a software painstakingly, eventually still did not find a don't money GUI tools, depressed, another idea, why not use Linux command line tool to compress ah, so found this tool on the Internet lame

First of all, of course, using homebrew to install lame

Dangchengchengdemacbook-pro:js dangchengcheng$ Brew Install lame

==> Downloading https://homebrew.bintray.com/bottles/lame-3.99.5.yosemite.bottle.1.tar.gz

==> Pouring lame-3.99.5.yosemite.bottle.1.tar.gz

Linux can be installed with the Apt-get install lame or yum install lame

The installation was successful.

In fact, compressing the audio file is nothing more than reducing the sampling rate, so lame will use the-B parameter to compress the audio in most cases.
