Customer Profile
Dominic Bilkey is Head of Sound and Video at a leading theater in London, where he oversees audio for some of the world’s most demanding live theater productions. With multiple auditoriums running two to three shows simultaneously, his team must maintain consistent sound quality across every stage. His work supports shows with large casts, rapid scene changes, and performers who move continuously between costumes, wigs, and roles, all while ensuring every audience member hears a flawless performance.
"In a musical, we might have 40 people changing costumes continuously. Ensuring that the mic position and sound quality is right on every single performer is critical."

In this environment, audio monitoring is never a one time task. Performers reenter the stage in new configurations throughout the show, and microphones are adjusted repeatedly as conditions change. Maintaining clarity requires constant awareness, clear communication, and complete trust in the tools supporting the team from the first entrance to the final curtain.
Why Is Audio Monitoring in Live Theater So Complex
The complexity of theater audio goes beyond channel count. Performers play multiple characters. They move through quick change areas. Microphones are repositioned repeatedly as costumes and wigs change.
"It's not put a mic on somebody and see you in two hours. Ten minutes later, they are in a different costume with a different wig, and we have to check and verify the mic position and audio quality again."
Monitoring tools must support that environment without slowing the team down or getting in the way.
How WAVETOOL 4 Supports Theater Backstage Monitoring Teams
WAVETOOL 4 gives backstage teams a single monitoring environment that brings wired and wireless channels together with clear visual context. With support for up to 192 channels and up to 8 concurrent users, multiple team members can monitor and troubleshoot simultaneously without waiting on each other or competing for access.
"The ability to have every wireless channel, every wired channel, visible within WAVETOOL to our backstage teams is invaluable in theater. It enables the team not only to monitor the RF system and the spectrum, but also the performers who are wearing mics."
The combination of visual reference and direct audio access allows engineers to immediately relate what they hear to the performer standing next to them.
Rather than switching between multiple applications to monitor different parts of the system, everything lives in one place.
"It brings all of those things together graphically and visually. In one screen, one piece of software."

Since backstage teams can identify and resolve issues independently within WAVETOOL 4, the front-of-house engineer stays focused on mixing the performance without interruption.
Why Is Direct Listening Essential for Theater Audio Teams
Meters provide valuable information, but in theater they rarely tell the full story.
"Metering enables the team to see the signal, but what it does not show is the pure audio quality."
Subtle issues such as hair brushing a lavalier microphone or vibration from instruments can only be identified by listening. WAVETOOL 4 allows engineers to listen directly to any source in the system, confirming audio quality with their ears instead of relying solely on visual indicators.
WAVETOOL 4 also includes intelligent mic issue detection that continuously analyzes audio to distinguish genuine microphone problems from expected production sounds. In theater, where loud moments that are parts of the show and subdued passages coexist within the same scene, this helps reduce false alerts and keeps the team focused on issues that actually require attention.
How Does Global Instant Replay Help Theater Teams Review Critical Moments
WAVETOOL 4's Global Instant Replay allows teams to rewind all replay enabled channels together and review up to 30 minutes of audio history without interrupting live monitoring. Whether an engineer stepped away from the station or was dealing with another issue, they can go back in time and listen to what they missed. Instead of relying on memory or secondhand reports, the team can listen back to the exact moment, identify the source, and determine whether action is needed.
"The timeline tools help the team manage problems in the moment. That ability to go back and listen to the audio is really valuable."
Session files can also be saved and archived, preserving a record of each production, its performers, and their headshots as part of the theater's permanent history.
How Does Mobility Improve Theater Workflows
Theater work happens everywhere at once. WAVETOOL 4 gives engineers mobile access via their iPad to:
- Listen to any channel from anywhere in the venue
- Troubleshoot mic issues at the source instead of from a fixed station
- Verify audio quality during quick changes without relaying instructions over radio
"The ability to use an iPad and roam freely backstage has been huge. The team can work with wigs, makeup, and costume teams wherever they are. There is no more moving headphones from one piece of equipment to another.”

How Built-In Chat Keeps Theater Teams Connected
Before WAVETOOL, backstage teams often had to rely on their phones to communicate back and forth, pulling their attention away from monitoring. WAVETOOL 4's built-in chat keeps the entire team connected within the same app where they are already monitoring, so no one has to switch between tools mid-show.
Chat is designed to stay tied to the audio context, with features built for the pace of live theater:
- Messages shared directly alongside channels and timelines
- Image sharing for confirming mic placement or stage conditions
- Reactions for quick acknowledgment without interrupting focus
- Speech-to-text for hands-free communication during the show

Why Do Theater Teams Trust WAVETOOL 4 Night After Night
After years of use, WAVETOOL has become part of the daily routine for Dominic Bilkey's team.
"It starts up every day. It runs in the background. The team expects it to be there."
A big part of that trust comes from how intuitive the software feels. The interface mirrors behaviors the team already understands. Touch a performer on screen and listen to them instantly. Tile channels across a display the same way you would arrange apps on a phone.
"The intuitiveness of WAVETOOL, the ability on our touch screens just to touch somebody and listen to them, feels very natural to the team. It's a tool that assists me to do my job, but it doesn't get in the way of doing my job."

With WAVETOOL 4, the team is particularly excited about the increased channel count for larger musicals and the expanded timeline functionality that allows them to review longer stretches of a performance. The updated interface also reflects a modern design sensibility that keeps the software feeling current without losing what made it familiar.
"WAVETOOL has fundamentally changed how we monitor productions. The ability to roam freely backstage while working with the wigs, makeup, and costume teams, with chat keeping everyone connected. WAVETOOL 4 gives the team the tools to accurately do their job."
