Modelling How Sound Engineers Counter Global Gain Rise in Live Mixes to Evaluate Possible Implementations of Automatic Gain Adjustments Modelling how sound engineers counter global gain rise in live mixes to evaluate possible implementations of automatic gain adjustments. Hannes Lindström Audio Technology, bachelor's level 2020 Luleå University of Technology Department of Arts, Communication and Education Abstract Smart tools for audio production have been making its way into modern audio production and is getting more popular in studio and postproduction work. In live sound however, there is few alternatives that exist. In this study live sound engineers experienced in live music sound reinforcement were interviewed about how they use gain and what considerations they make when adjusting gain. The aim of this study was to use their answers to create the foundation of a framework to an algorithm that can adjust gain automatically. The interviews were semi- structured, and the transcriptions were analysed using grounded theory. From the transcripts five categories were created and further divided into subcategories for deeper analysis. The study showed that the data in the study could not easily be proceduralized but instead two alternative ways of implementing this in practice, one that monitors the input signals and passes the information to the engineer. And another that adds a control layer to the monitoring where the parameter can be selected based on mixing strategy and the algorithms control can be switched on or off.

I’m excited to be sharing the information in this eBook with you. Mixing live music has been my passion for a long time and I’ve been fortunate to make a career out of it for nearly 30 years! During that time, I’ve met a lot of people interested in learning live sound but having no idea where to start. “What do I need to know”, they always ask? There is just so much to learn- from a wide range of audio consoles to system processing, so many different microphones, speaker systems, wireless systems, in-ear monitors, plug-ins, and that’s just technology! What about EQ techniques, power requirements, dealing with RF, how to get rid of feedback, how to choose the right microphones, how the whole sound system goes together… I’ve also encountered those who have been mixing sound for live shows and events but struggling to achieve their desired results, because they lack knowledge of the core principles. They just can’t quite get the vocals loud enough without feeding back or their mixes are lacking clarity and definition, everything is just muddy sounding or the instruments are all fighting for the same space.

It focuses on music performance models outside the ‘playback media’ (e.g. DJ) traditions where full mixes are played back or manipulated. In other words, it focuses on ‘instrumental style’ performance. This may, however, include samplers and electronics in performance. The paper seeks to examine the relationships between the gestural, performative and technological practices of the recording studio and emerging performance practices in the 21st century and propose an initial taxonomy of the major developments in the last 20-30 years. It argues that recording and performance practices are trending towards each other and that this is underpinned by technological shifts, a change in the level of production literacy of musicians broadly, and an increasing shift towards more technologically intensive performance, either on stage (in terms of the musician’s own performance tools) or off stage (in terms of the increasing sophistication of live sound production technologies).
