TuneBoxNo more sound that lets you down right when it matters.
TuneBox — automatic live sound calibration and room EQ for DJs, bands, churches and events
Plug in, let TuneBox listen to the room, and play. In a few minutes your sound is clean and balanced in the real venue — with the gear you already own, no processing rack and no sound engineer needed.
TuneBox is Windows software that turns the laptop and audio interface you already own into the sound processor for your event. It measures the real venue — your speakers, your room — corrects the equalization automatically and runs in real time during the party, the service or the show, delivering professional sound in minutes, with no processing rack, no sound engineer and no gear swap. Built for DJs, volunteer church sound operators, duos and bands who run their own sound on small and mid-size systems, TuneBox speaks your language: it recommends, explains why in plain words, and you just confirm.
- Automatic calibration guided by real measurement: a step-by-step assistant measures the room acoustics (including reverberation) and equalizes each speaker individually — fixing both excesses and deficits — with clipping protection.
- Automatic feedback suppressor: a quick calibration before the event maps out the room squeal points — and during the show it keeps listening and locking down the ones that only appear with a full room, the band playing and singers on the mics. Surgical cuts that leave the rest of the sound alone: you get room to push the microphone far higher than you could without it.
- In case you don't have a measurement microphone: it supports 31 ordinary microphone models with a built-in correction curve — you measure with the mic you already own.
See all features
- Three output topologies solved in software: stereo L/R, main speaker + subwoofer (with a crossover derived from the measurement) and main speaker + fill speaker with automatically aligned delay — the cure for muddy sound at the back of the hall.
- Smart, explained recommendations: the program suggests the best setup for your room and tells you why in plain language; the final call is always yours.
- Live mode (cockpit): real-time bass, mid and treble coloration, “original × treated” A/B comparison at matched volume, and an always-on protection limiter.
- Flexible capture: plays straight from the PC itself (VirtualDJ and similar) or takes the signal from a mixer/controller with low-latency ASIO — with the microphone mixed into the music.
- 100% offline operation at the event: no cloud, no recurring login; internet only for activation. If the computer restarts mid-event, you are back to calibrated sound in minutes, redoing nothing.
- Flexible, fair licensing: lifetime (with free updates) or monthly/quarterly/yearly subscription; transferable between machines without limit (one at a time).
- Bring your own gear (BYO): works with your compatible audio interface, your microphone and a free sound-level meter app on your phone.
- VST3 effects on the microphone: use plugins you already have installed on your PC (free or paid) only on the mic path — live pitch correction, vocals and guitar with different treatments, or two karaoke mics each with its own effect. Never touches the mixer sound.
- Saved setups per venue: store each room calibration under its own name — and the feedback suppressor travels with it, including everything it learned during the event. The second time you play that hall, you load the setup and you are on the right sound in seconds, with no measuring to redo.
For systems with up to 2 outputs — L/R speakers, main + sub, or main + fill. Requires a Windows PC and a compatible audio interface and microphone.

Have you been through any of these?
The microphone squeals out of nowhere and everyone covers their ears.
Nobody can understand the vocals — they vanish into the music, especially in a big hall.
It sounded great at home. In the venue it became something else: muffled or muddy.
The bass booms and swallows everything, or it goes thin and lifeless.
In case you're not a sound engineer and have no idea where to touch to make it better.
Every place is different and you start from scratch every time, guessing.
If even one of these rings a bell, keep reading.
It's not you. It's the room.
The room is sabotaging you.
The same speaker that sounds full and rich in one place turns muffled somewhere else, or muddy somewhere else. That is not a flaw in your gear or a lack of skill on your part: every room boosts some sounds and swallows others. A church, a hall and a gym each treat the same sound in completely different ways.
TuneBox is a computer program that listens to how the sound reaches people's ears in that place and fixes everything on its own — using the gear you already have. The result is balanced sound, no boomy bass and no missing sparkle, wherever you play.
The same speaker, the same sound — and each room giving it back differently. TuneBox measures that difference and corrects it.
Three steps, and the program does the heavy lifting
It listens to the room
With a measurement microphone, TuneBox plays a test sound and hears how the room responds. That is how it discovers what the room does to your sound — something the ear alone cannot quite catch.
It fixes the sound on its own
The program works out and applies the adjustments: it removes the excess and restores what was missing. You touch nothing — the muffle is gone, the boom is gone, and the music comes out clear and balanced.
You add the final touch
Want more bass for the beat? More sparkle for pop? Three simple controls shape the sound to your taste — and you can hear the "before and after" instantly, at the same volume.
Every pain has a cure inside
Stops the microphone squeal
It spots the frequency about to squeal and pulls down only that one, before it blasts into everyone ears — and it does not stop at setup time: it keeps watch through the whole event. What it learns is stored with that venue setup, ready the next time you play there.
Makes the voice understood
In a big hall it aligns the timing between speakers so the voice arrives intelligible at the back — without the echo that muddies every word.
Balances the sound in the real room
It measures the space and fixes the booming bass, the missing treble, the muffled midrange. The sound is full without excess — in the venue, not just at home.
Doesn't require you to be a technician
TuneBox is an assistant: it recommends and acts on its own, in plain language. Anything it decides, you can adjust or undo.
Skips the rack
On your computer it does the job of a professional sound processor, using the audio interface you already own. No rack to buy or haul around.
Pick up right where you left off
A brief power cut stopped the event? You jump straight back into Live and resume instantly — no redoing the measurement, no reconfiguring anything, with the audience still there.
Whatever kind of event you run
DJ and parties
Plays straight from your music software, adjusts the EQ live, and keeps the floor packed without the sound tiring the ear.
Live band
Pulls sound from your mixer or controller, delivers monitoring to the musicians, and fixes the big hall where the vocals usually disappear.
Church and talks
Clear voice from start to finish, with the mic guarded against squeal through the whole service — and no need for a sound engineer on call at every event.
Sound freelancer
Carry TuneBox on a flash drive and arrive ready in any room: it measures the place on the spot and delivers the right sound, wherever the gig is.
At the event, no surprises
You activate the program once, at home or in the studio, with internet. After that it runs on its own — in the gym, the countryside, the hall with no signal. No constant logins, no cloud, no hassle.
What you need to have
TuneBox is the program — the brain. It works with the gear you already use. We sell no hardware at all: you use your own.
A Windows PC
That is where TuneBox runs: the laptop you already take to the event. It is the computer that measures, corrects and runs the sound in real time.
Your USB audio interface
That little box that already connects your computer to the sound system. TuneBox checks whether yours is up to the task and warns you clearly before you start.
A measurement microphone (or one of the supported microphones)
It's how the program listens to the room. Don't have one? You can use an ordinary microphone: TuneBox corrects the difference, with honest caveats.
Your phone with a decibel-meter app
A free sound-level app (a decibel meter) on your phone helps set the level safely. That's all.
TuneBox Voice FX: the plugin that treats your microphone
A free plugin we built that runs inside TuneBox and takes care of the live vocal: it cuts background noise when nobody is singing, evens out the quiet talker against the one who belts the chorus, and gives the voice some room. Just a few controls, already tuned — you switch it on and sing. No subscription, no separate purchase: it is yours along with TuneBox.
Subscription or lifetime license
Both use the same program, with your own gear. Only the license changes: lifetime (yours forever) or by period.
Subscription
The same program for a period — monthly, quarterly or yearly. A good option for seasonal use, without the lifetime license. Uses your own gear.
Lifetime license
Works with the audio interface and microphone you already have. The program checks whether your gear is up to it and warns you clearly before you start. License yours forever, transferable between computers.
Play knowing the sound is right.
Let TuneBox take care of the room so you can focus on what matters: your music and your audience.
