One of the main objectives of this course is to ensure that practice in digital audio is represented by complete. This includes topics such as: virtual studio (DAW) along with tools like Pro Tools and MIDI controllers; hard disk recording and multitrack recorders. The objective of this course is to explain the topic of sound in simple form, in terms that are acceptable to both the creative people in production, including authors and interpreters, and for those who deal operationally with the sound mixing and recording or with its engineering aspects. Exploring the common ground of all these groups, the work of each can be interpreted by the other. It is also designed for those who would like to explore the techniques of audio that have been developed in fields that are more remote than their own, whether radio, musical recording, television or sound for cinema.
