Audacity is a free, easy-to-use audio-editing program. With Audacity we can record our own sounds and music, or we can work with existing audio files. These activities cover: the Audacity interface, controls, and track control panel; importing and playing audio tracks; editing techniques: selection, cut, copy and paste; labeling; amplification and other special effects; trimming, rearranging, and time shifting; noise removal; voice removal; varying tempo, speed, and pitch; normalization, equalization and compressor; recording sound, and overdubbing; creating a music mix and exporting. They also include theory on sound, file formats, sound quality, recording as well as a glossary.
All audio files required for the activities are available as a free download through a link at the bottom of the title page.
