Module Content
Outline Syllabus:
Digital Audio Signal Path
A/D converter topologies – advantages and disadvantages of individual approaches. Clock function and distribution; dithering function and options; compatibility issues; digital audio transmission standards – AES/EBU, SP-DIF, T-DIF, MADI; metering considerations. Quality considerations in digital systems – jitter, PLL stability.
Digital Audio Networking
Networking basics; OSI model; switching and routing; Layer1,2 and 3 approaches and standards; circuit switched vs packet switched approaches. Switching and routing, network topologies, switch configuration. AoIP protocols and implementations – Dante, AES67, Milan.
Digital Signal Processing
Digital filter implementation. Convolution. Reaktor software as an audio processing development tool. Design of digital audio processing tools using modular software such as Native Instruments Reaktor – reverberation, EQ, dynamics, spatial modulation.
Spatial Audio Techniques
Psychoacoustic principles. Stereo. Binaural. Multichannel. Ambisonics. Dolby Atmos. Creative Spatial Audio Effect Design.
Data Compression
Information theory and notions of redundancy; lossless compression – Huffmann, LZW; lossy compression precepts; architecture and operation of MPEG 1, MPEG2 and AAC audio codecs; compression artefacts and what to listen for; objectively evaluating codec performance.

Module Overview:
This module is intended to bridge the gap between theoretical concepts and their application especially those relating to current developments in digital audio system related areas such as signal processing, networking, data storage and transmission, and immersive audio.
The content is delivered through lectures where the various ideas are introduced and discusses, and a variety of workshops in the recording and digital audio lab where a variety of tools can be designed, and systems can be compared for the purposes for understanding the technical components within a familiar practical setting.
