Audacity is developed by a team of volunteers and released under an open-source license and is the only audio editing software that is run on Mac's, PC's, and Linux computers. Go to http://audacity.sourceforge.net/ to download the most current version 1.3.13 Beta.

Getting Started

Open Audacity found in the applications folder.

(preferrably after every edit) File > Save navigate to your hard drive and create a folder with your name and save it to that folder. This folder will contain all your audio files and edit information so you can continue to work on different computers so keep this folder and it's information contained.

Inside your folder there will be the Audacity project file with a .aup extension and a folder ending with _data.

For example, inside the folder called interview if the project was named October there would be a file called October.aup and a folder called October_data.

Always keep the project file and data folder together.

Importing audio
