This lesson covers digital audio media, including identifying the capabilities and limitations of various audio software and understanding different audio file formats and their properties. It discusses common audio editing software such as Audacity, Pro Tools, and GarageBand and their typical capabilities, like cutting, copying, and pasting audio, adding effects, and recording. The lesson also examines audio file formats like MP3, WAV, and WMA, how they vary in size, quality, and compression, and which formats are best for different devices. Students are asked to research and summarize specific audio software and file formats based on their characteristics, capabilities, limitations, and compression levels.

9. Identify capabilities & limitations
Know audio file formats
Audio Platforms
Because there are so many different audio playback devices,
various file formats are required to cater for each one.
Some devices will sacrifice audio quality for smaller file sizes
while others required top quality audio regardless of size.
Audio file formats can vary in:
File Size
Quality
DRM
Compression
