Overview

Audio Signal Processing I provides students with a foundational and practical understanding of essential audio processing techniques used in music production, audio post-production, and sound design. This course introduces and explores core signal processing tools and concepts, with a focus on how each category of processors affects the tonal, spatial, and dynamic characteristics of audio.

Module One: Equalizers

Module Two: Dynamic Processors

This module explores the principles and applications of dynamic processors, including compressors, limiters, gates, expanders, and de-essers, teaching students how to control volume fluctuations and shape the impact of audio signals. Through detailed breakdowns of each processor type—such as VCA, optical, FET, and Vari-Mu—students gain the skills to enhance clarity, maintain balance, and add character to mixes.

Module Three: Harmonic Processors

This module examines the creative and technical use of distortion and saturation processors, including overdrive, clipping, bit crushing, wave shaping, and tape simulation. Students will explore how different types of harmonic processing—from warm analog emulation to aggressive digital effects—can enhance tone, shape dynamics, and radically transform sounds in music production.

Module Four: Stereo Processing

This module explores stereo imaging techniques that shape the width, depth, and spatial placement of audio, from basic panning and Mid/Side processing to advanced widening tools like stereo imagers, Haas effect, and artificial double tracking. Students will learn how to create immersive, professional mixes while maintaining mono compatibility and spatial balance across instruments and effects.

Module Five: Audio Repair & Restoration

This module provides students with practical skills in identifying and repairing common audio problems using professional audio restoration tools. Students will explore a range of corrective processors designed to address issues such as background noise, clipping, reverb, mic handling artifacts, and tonal inconsistencies.

This module explores the fundamental and advanced uses of equalizers (EQs), teaching students how to sculpt and balance audio using parametric, graphic, shelving, dynamic EQs, and filters. Through detailed techniques and real-world use cases, students will learn how to enhance clarity, fix frequency issues, and apply EQ creatively across various instruments and mixes.
