Running Sound for an Esports Watch Party, Casters First

A bar manager called me in a panic two days before a regional final watch party. Her staff had tried a dry run with the stream on the projector and the house playlist on the PA, and nobody could hear the casters. Turning the stream up made the music distort. Turning the music down made the room feel dead between games. She asked if I could "just DJ it."

I could, but not in the way she meant. An esports watch party is not a DJ gig with a screen in the corner. The casters are the main act, and the job is to make two people talking over a laptop sound clear to two hundred people, then fill the gaps without stepping on them. I have done about a dozen of these now. This is the setup I bring and the mistakes I made on the first few.

Getting the stream into the mixer cleanly

Most venues run the stream from a laptop plugged into a projector by HDMI. The audio either goes along the HDMI to the projector's tiny speaker, or someone runs a cable from the laptop headphone socket into the PA. Both are bad.

The headphone socket route has two problems. The signal is unbalanced and weak, so after a long run it picks up noise. Worse, a laptop on its charger, plugged into the same building power as the PA, very often produces a ground loop hum, a low buzz that gets louder as you raise the stream. At my first watch party that hum sat under the casters for the whole first map, because I had not brought the one cheap box that fixes it.

That box is a passive DI with a ground lift switch. Laptop headphone out goes into the DI, the DI's balanced output goes into a channel on my mixer, and the ground lift kills the hum. A better option, when the venue allows, is an HDMI audio extractor between the laptop and projector, which pulls a clean digital or line level signal off the HDMI before it ever reaches a headphone amp. Either way, the stream lands on its own mixer channel with its own EQ and fader, just like a deck.

Set the laptop's volume to maximum and the stream player to maximum, then control level only at the mixer. When the laptop volume sits at 40 percent, you are throwing away signal and adding noise later. And turn off every notification sound on that laptop. A Windows error chime through a full PA in the middle of a clutch round is a memorable way to lose a room.

Making caster voices cut through a loud room

Esports casting is fast, excited speech layered over in-game sound effects, mixed at the broadcast end for headphones and small speakers. On a PA in a room full of people it turns muddy quickly. The fixes are mostly EQ on the stream channel:

• A high pass filter around 100 Hz on the stream channel. Game explosions and caster mic rumble eat headroom without adding clarity.
• A small cut around 250 to 350 Hz, where crowded rooms build up boominess.
• A gentle lift of 2 to 3 dB in the 2 to 4 kHz range, where consonants live. That is the difference between hearing "he's flanking" and hearing a shout.

Leave 6 dB of headroom on the stream channel during normal play. Casters will scream when a fight breaks open, and the crowd will scream with them. If you are already near the top of your meters, the big moment turns into distortion right when everyone is listening hardest.

The same principles of carving space between two sources that I use for mixing tracks, covered in using EQ to make two tracks sit together, apply between the stream and anything else in the room.

The breaks are where you earn the fee

A best of five series has long gaps. Between maps there is often a ten to fifteen minute break, plus technical pauses that nobody announces in advance. Broadcasts fill this with replays, sponsor segments and a countdown, but a room full of people does not want to sit through an ad read at PA volume.

My approach: when the broadcast goes to break, I fade the stream channel down over two or three seconds and bring music up. I play upbeat but not peak tracks, nothing that tempts people onto a dance floor they will have to leave in ten minutes. Game soundtracks, especially from the title on screen, work well here. When the broadcast countdown appears, I start bringing the music down so the stream sits at full level about thirty seconds before the players load in.

The common advice is to set a sidechain compressor so the music ducks automatically whenever casters speak. I tried it and stopped. Casters talk through breaks too, half finished thoughts and sponsor chatter, and the music pumped up and down constantly. Manual fades with my hand on two faders sound far more natural, and they let me decide when the casters matter.

Delay, phones and the spoiler problem

Every stream has latency, often several seconds and sometimes much more, depending on the platform and the player's settings. Half the crowd will also be watching on their phones. If someone's phone is ahead of the projector, they will cheer a kill before the room sees it. There is no fix for that, only reduction: set the stream player to its low latency mode if the platform offers one, and avoid running the venue's stream through a second service that adds delay of its own.

Some publishers also have viewing party rules about charging entry or using their logos, and those rules change between seasons. That is the organiser's job to check, but I ask, because it is my rig on the flyer photos.

The mic for the host

Most watch parties have a host doing raffles and announcements between maps. Give them a handheld dynamic mic, not a headset, and gate it so it is muted while the stream is up. A host who forgets their mic is live and comments over a final round is the fastest way to annoy a room that came for the casters. I wrote about choosing those mics in picking a microphone for event MC work. If you already run big sports nights, much of DJing a sports bar on a big match night carries over, with one difference: esports crowds hate missing a single word of the commentary.

Rehearse with a VOD before the night

This week, pull up a past broadcast from the same game, play it through your actual rig at the volume you expect to use, and stand at the back of the room. If you can follow every caster call, including during the loudest fight in the VOD, your EQ and headroom are right. If you cannot, fix it now, while the only person in the room is you.
