Students will learn how we understand sound from a physical perspective. Next they will familiarize with audio conversion from its physical representation into analog, and later by sampling, into a digital form. Students will have a possibility to gain insight at how the subsequent audio processing works by means of audio fitration and effects, and will learn which file formats are used in both uncompressed (WAV) and compressed audio such as MPEG Audio Layer 3 work. Later in the course, students will familiarize with speech synthesis and speech-to-text recognition. A practical aspects of sound identification, such as during investigation and forensics, will also be discussed. The final lecture will be dedicated to the world of music.

Study Objective:

The goal of the course is to provide students with a basic undestanding from the audio digitization theory. After discussing physical audio principles, students will learn how audio is represented in analog and digital forms and how to save it into a computer. Students will also acquire basic information about audio processing i.e. filtering, analysis, and synthesis.
