Multimedia Module 1 – Audio Editing
The Audio Editing module requires the candidate to understand the basic principles of digital audio
representation and to be able to perform different tasks on audio feeds (music, dialogue, noise). The
candidate shall be able to use programs for digital audio processing, suitable for soundtracks to be used on
multimedia projects.
