LET THE CROWD
DECIDE.
Two sides of the crowd battle by how loud they cheer, like HOME 92 vs AWAY 87.
The crowd's voice becomes the show.Turn halftime, timeouts and changeovers into a live game the whole crowd plays.
THE CROWD IS THE SHOW.
Between plays. Halftime. Timeouts. Changeovers at events.
Turn the usual waiting time into entertainment the whole venue takes part in.
KoeBattle measures how loud the crowd is in real time and shows the result on the big screen: a crowd-participation noise battle.
One PC and a microphone. No internet needed.
10 SECONDS. ONE ROAR.
Each measurement lasts 10 seconds (adjustable); a round takes about a minute. Two teams get a split-screen VS, three or four get voice waveforms. Ties show DRAW, and any round can be measured again. The call-out text is editable (default: MAKE SOME NOISE!).
WHO'S LOUDER?
Mash the buttons to cheer. The battle is decided in 10 seconds.
This is a web demo. At the venue, the crowd's real voice is measured with a microphone, not buttons.
SEE THE SOUND.
The crowd's noise, visualized in real time.
Cheer, and the meter on the big screen moves.
So the crowd cheers even louder.
Scores are not decibels but a voice score from 0 to 100, measured against a baseline taken in the quiet venue. Three meter styles: bar, speedometer, ring.
2 TEAMS? 4 TEAMS? BRING IT ON.
Up to four teams, measured one at a time or all at once (one stereo feed from the house mixer for two teams, or one USB mic per team).
NOT JUST FOR SPORTS.
YOUR VENUE. YOUR COLORS.
YOUR BATTLE.
The setup screen previews the title, call-out, measuring and result scenes with mock scores. No need to run the show.
GAME × SPONSOR
Show a sponsor credit and image on the title and result screens. The event title, team names and colors, and the background can all match the venue. For sponsor activations and fan engagement.
THIS IS THE REAL THING.

- Separate video inputs: two outputs, each full screen
- One combined signal: multi-row ribbon deliveries (e.g. seven rows over two signals, with a shorter camera-position row)
- Another PC or OBS: open the URL from any PC on the LAN, or load it as a transparent browser source in OBS and send it over NDI®
SET UP IN 10 MIN.
Plug in a mic: USB, built-in or a line from the house mixer.

FAQ
What kind of microphone do I need?
A USB microphone or the PC's built-in mic both work. A directional mic pointed at the crowd gives clearer differences. A line feed from the house mixer works too.
Are scores in decibels?
No. Scores run from 0 to 100. A baseline is taken in the quiet venue and scores are the difference from it, which makes them less dependent on the microphone's sensitivity. For fairness between teams, place the mic at a similar distance from each section.
Can teams be measured at the same time? How many?
Yes. In simultaneous mode all teams are measured at once, with one meter per team on the big screen. Use one stereo feed from the house mixer (left and right for two teams) or one USB microphone per team, up to four teams. The one-mic, one-team-at-a-time mode is still available.
Do I need an internet connection?
No. It runs on one PC with a microphone (Mac needs Chrome).
Can we change team colors and logos?
Yes. Team names, colors and logos, the background (image or video), sponsor credits and text can all be changed, with a preview before you save.
Can the big screen and the ribbon show different pictures?
Yes, in three ways: two outputs each full screen, one combined "composite" signal, or a browser on another PC on the LAN or OBS over NDI®.
Is it available in English?
Yes. Switch the control screen between English and Japanese with the buttons at the top right. The big screens have their own language setting, so staff can operate in one language while the screens show the other. The operating manual is included in English.
Does it play sound effects?
No. Sound from the house speakers would be picked up by the mic and distort the scores. Leave the hype to the DJ and MC.
Does it run on a Mac?
Yes, on Apple-silicon (M1 or later) Macs. We send the Mac version separately when you order. Full-screen windows use Google Chrome.
Can I use it on the same PC as DokoDoko or OtoMotion?
Yes. Even when other DBT products are running at the same time, each uses its own port and stopping one does not stop the others. KoeBattle also ignores other products' license files.
Which PC?
A recent Windows 10/11 PC or an Apple-silicon Mac, with Edge (Windows) or Chrome (Mac; install Chrome, it is used for the full-screen output). For video backgrounds, a PC with hardware video decoding is recommended.
Can we try it before ordering?
Contact us and we will send a time-limited trial license. Download the app from the download page; it starts once the license arrives. The Mac version is sent separately, trials included.
