Celebration of Chris Tobin

Alex and I attended the Celebration of a fellow engineer Chris Tobin.

I was on the TWRIT show three time I think with him.   Solid questions, great interviewer, great ethic.  I watched Many hours of him sharing wisdom with the internet.  Smart guy and busy busy busy doing the worlds most amazing project.    Some of his brilliance was captured on this week in radio tech

He was taken too soon.


We talked about the Emoji description protocol

Analog out… that means… what….?

AES – SC-05-05 – X-152 – Call for participation


The goal / target / deliverable is a template that manufacturers could include in their manuals that explain the characteristics of the signals leaving devices and the characteristics of signals a device is capable of receiving. Having these parameters summarized in a consistent way will help users integrate equipment.


Working Group on Grounding and EMC Practices

Group Scope: The scope of the SC-05-05 Working Group on Grounding and Electromagnetic Compatibility Practices shall include, within the bounds of the scope of SC-05, all practices affecting usage and performance of audio hardware, with respect to the susceptibility of the signals it carries to effects such as noise and cross-talk due to the manner of its connection and construction, and the effects of its signals on other hardware and systems in its vicinity. It shall not set standards for personal safety with regard to such connections and construction but shall keep safety considerations in mind in its recommendations.

Microphone Description Protocol

This is an idea about a byte efficient protocol that describes the contents of an audio channel. At first, you may laugh…

It uses UNICODE characters as a method to condense the language needed to describe something in the field. There are Emoji for so many generic audio terms.

An Emoji is 4 bytes to encode using UTF-8.

Framework: Emoji followed by a description repeat. n feeds n+1

No Emoji = end of sequence

Signal Path is in the order it is displayed

To describe a person at a microphone, their role and info about the microphone and how it’s connected to the system a series of Emojis followed by text can be concatenated


Using this concatenation you can build up descriptions of the source

How to create a mix
A mix is made of a web of sources at a particular level

I did a quick test in Google sheets and it does parse the UNICODE as strings
