Introduction to Audacity

What is Audacity?
Audacity was started as a research project by Roger B. Dannenberg, a professor of computer science, art, & music at Carnegie Mellon University, along with his graduate student Dominic Mazzoni. It has grown into one of the best audio editing software available today. Audacity is free and open-source, meaning its source code is accessible to everyone.
This openness encourages volunteers to contribute by fixing bugs and creating extensions. The software is a digital audio editor used for recording and editing audio and is compatible with Windows, macOS/OS X, Linux, and other operating systems. Audacity does not require a sound mixer or any sophisticated equipment, making it easy and accessible to use.
