Hear it. Fix it.

Describe the problem in plain words, like "the vocal sounds muddy." EQExpert names the source, gives you a practical starting move, and draws it on the EQ curve. Then your ears make the call.

Free to start. No password. Built for the phone in your pocket at the console.

How it works

Three steps. No jargon required.

STEP 1

Describe it

Muddy. Harsh. Buried. Underwater. Use the words you would say out loud. EQExpert connects them to the right source and frequency zone.

STEP 2

Get a starting move

A practical first move with the range, the amount, and the why. You see it on the curve before you touch a knob.

STEP 3

Verify with your ears

Listen in the full mix. Keep it if it helps. Undo it if it does not. Your ears make the final call, every time.

EQExpert does not replace your ears. It helps you understand what they are already telling you.

No magic numbers. No guaranteed fixes. And when the console is not the problem, it says so: sometimes the answer is gain, mic placement, or the source. That honesty is the whole point.

Soundcheck Mode

Check every channel, before the room fills.

Go source by source with the band: gain first, HPF, a quick look, and the usual suspects for each channel. The same calm order, every week.

  • Stage order that makes sense. Drums, then instruments, then singers, then speakers
  • Listen-for-these prompts so you catch problems early
  • Big type on request, readable from the console in a dark room

Feels like an app

On your home screen, ready at the console.

EQExpert opens like an app on your phone, greets you by name, and gets you from problem to move in seconds. When something is on fire, the one-tap rescue buttons need no typing at all.

  • Feedback, dead channel, hum, clipping: guided rescue, one step at a time
  • The EQ graph on every answer. Free, and it stays free
  • Sign in with Google or a 6-digit code. Never a password
