Audio Essentials

One Day Course

Overview

Always wanted to know your mp3s from your WAVs but were afraid to ask?

This course is designed for those who work with audio and have some understanding but need to know more about compression, file-formats and limitations of digital audio files.

The essentials are stripped down and presented in as non-technical a way as possible and audio samples are used throughout the course so you can actually hear the different results. You need no previous experience to attend this course.
