Prerequisites

Familiarity with computer audio/video files Familiarity with installing computer-based software from a website (Very) Basic programming skills (primarily in Matlab and Python) Equipment and software: A computer with internet connectivity Open-source software (that will be downloaded from the internet or will be provided along with the course material, as the situation may demand) COURSE SYLLABUS Module 0: Before the course A general overview of the course and its contents in broad strokes, including a brief preface or prologue of sorts. Perhaps a list of some suggested reading material for familiarization with the subject matter. Module 1: Digital Audio: Basic Concepts and Principles This module covers the fundamentals of digital audio and audio processing. Coverage includes an overview of the digital audio capture process, the processes of analog-to-digital/digital-to-analog conversion, and concepts of filtering & sampling. Basic principles of digital audio encoding and audio formats, data losses & impairments, and important audio processing operations including noise reduction and compression are also covered. Note that the primary objective of this module is to familiarize the participants with those technical aspects of digital audio and audio processing that would be useful to them from a forensic standpoint. Description of basic concepts of digital audio: Audio capture process, analog-to-digital/digital-to-analog conversion, filtering & sampling Audio encoding & formats, audio compression Overview of technical issues related to audio recordings: Data losses and impairments (aliasing, jitter, quantization errors, clipping, transmission & generation impairments, encoding & transcoding impairments) Tools covered: To be announced soon!
