How to download and use the recording software, Audacity, on a Macbook

I am spending some time getting to know my MacBook, and today I decided to download Audacity.  Audacity is a tool you cannot do without to make audio podcasts personally or in the classroom. It is a free, easy-to-use, multi-track audio editor and recorder for Windows, Mac OS X, and other operating systems. The interface is translated into many languages. You can use Audacity to record live audio. I love this application. I use it constantly on my Windows laptop. Here are the steps I took:

Step 1: Download Audacity 

I asked Google for 'Audacity for Macbooks and it took me to this website: 

http://www.audacityteam.org/download/mac/ . 

I selected the download link to Audacity 2.1.2 .dmg file (33.1 MB, includes help files) and started the download process of downloading the disk image into Downloads on the Mac.

Step 2: Download Lame
Lame enables one to save Audacity recordigs as MP3sso further down the page under Optional Downloads, Plug-ins and Libraries there is a download button for Lame:

LAME MP3 encoder – Allows Audacity to export MP3 files.
This disk image also downloads into Downloads

Step 3: Install Audacity
Ooops, I discovered that my Macbook wouldn't oinstal Audacity because it was downloaded from an unkown source! Fortunately i found the solution on the Internet: 'Change Gatekeeper Settings: Open the System Preferences. Open the Security & Privacy pane by clicking Security & Privacy. Make sure that the General tab is selected. Enter your username and password into the prompt that appears and click Unlock.' It worked! I could continue!

Under the Finder in the dock find the disk images in Downloads and click on both to open a window for each one. Start with Audacity. Make a folder called Audacity in Applications and drag the disk image across. Then eject the disk image from the Finder menu.

Step 4: Install Lame
Click on Lame to open it. You'll need to open Preferences to enable the recording to be saved as a MP3 file. 

Once everything is installed you'll find that Audacity works like a charm. The recordings are saved in the Audacity folder in Application
