An Investigation of Protocol Command Translation as a means to enable Interoperability between Networked Audio Devices Submitted in fulfilment of the requirements of the degree DOCTOR OF PHILOSOPHY of Rhodes University OSEDUM P. IGUMBOR February 2013 Abstract Digital audio networks allow multiple channels of audio to be streamed between de- vices. This eliminates the need for many different cables to route audio between devices. An added advantage of digital audio networks is the ability to configure and control the networked devices from a common control point. Common control of networked devices enables a sound engineer to establish and destroy audio stream connections be- tween networked devices that are distances apart. On a digital audio network, an audio transport technology enables the exchange of data streams. Typically, an audio transport technology is capable of transporting both control messages and audio data streams. There exist a number of audio transport technologies. Some of these technologies implement data transport by exchanging OSI/ISO layer 2 data frames, while others transport data within OSI/ISO layer 3 packets. There are some approaches to achieving interoperability between devices that utilize different audio transport technologies. A digital audio device typically implements an audio control protocol, which enables it process configuration and control messages from a remote controller. An audio control protocol also defines the structure of the messages that are exchanged between compli- ant devices. There are currently a wide range of audio control protocols. Some audio control protocols utilize layer 3 audio transport technology, while others utilize layer 2 audio transport technology. An audio device can only communicate with other devices that implement the same control protocol, irrespective of a common transport technol- ogy that connects the devices. -

SOUND DESIGN LIVE: Build Your Career As A Sound Engineer By Nathan Lively Humbly dedicated to Steve Brown, who succumbed to cancer shortly before this book was published. His work embodies the community-building sensibility to which I aspire. He will be very much missed in the global community of sound designers and theatre, in which he played a major part. July 8, 2013 ACKNOWLEDGMENTS The material in this book comes from the massive generosity of the 19 people I interviewed during my first two years producing the Sound Design Live podcast. Their desire to spread valuable information and see others succeed in the area of professional audio is inspirational to me, and comprises the backbone of my work. I would also like to thank Elis Bradshaw and Ben Kates for performing literary miracles with my talky words, Mark Winslett and Mercedes Groff for the cover design, and Craig Sullender for continued support. FOREWORD Audio engineering technology has changed, but the work is still all about connections. Not through CobraNet®, Dante® or AVB but rather the personal connections of telephones, email, social media, and old-fashioned face-to-face. Connecting to creative artists, crew, managers, producers and audiences. If you are already in this field, you are somewhere in this interconnected network. If you are wanting to get involved, welcome to the ultimate work in progress. This book is all about connections and why they are the most important, valuable, and motivating forces in the industry. Nathan Lively plays the role of network hub and monitors traffic in this book to give you a glimpse into the absolutely real experience of our peers and mentors in this trade.
