macOS gives you one volume slider. EQBase gives you control over everything your Mac plays.

It processes music, browser video, calls, games, and system sounds before they reach your headphones, speakers, or display. Start with a 10-band equalizer and more than 8,600 AutoEQ headphone correction presets. Use per-device settings, hotkeys, volume boost, and balance to make every setup sound right. Record processed system audio in one click or route selected apps to the right output.

EQBase Pro adds a 24-band parametric equalizer with dynamic and linear-phase modes, a live spectrum analyzer, separate left and right EQ, room correction with FIR convolution, spatial audio and crossfeed, Audio Unit hosting, and App Mixer per-app volume control.

EQBase is signed and notarized for macOS 14 or later on Apple silicon and Intel. The free tier has no time limit. The direct signal path adds zero samples of latency and stays bit-perfect when flat.

Questions & Answers

As answered by people managing Equalizer APO and EQBase.

Who are some of the biggest customers of your product?

EQBase's answer:

EQBase is sold directly to individual Mac users and does not publish customer names or usage data.

What makes your product unique?

EQBase's answer:

EQBase combines simple everyday controls with professional audio tools in one native macOS app. It can improve laptop speakers, apply a measured headphone correction, control individual app volumes, route audio, and record system sound. The direct signal path adds zero samples of latency and stays bit-perfect when flat, with live verification inside the app.

Why should a person choose your product over its competitors?

EQBase's answer:

Choose EQBase when you want more than a basic system equalizer. Its permanent free tier covers everyday EQ, volume control, and headphone correction, while Pro adds parametric EQ, room correction, Audio Unit hosting, App Mixer, routing, and recording. It is built for people who want both an easy first adjustment and deeper control when they need it.

How would you describe the primary audience of your product?

EQBase's answer:

EQBase is for Mac users who want better control over everything they hear. That includes everyday listeners, headphone enthusiasts, people using external displays or fixed-volume outputs, multi-app power users, creators, and audio professionals who need precise monitoring tools.

What's the story behind your product?

EQBase's answer:

macOS gives users a master volume slider, but no system-wide equalizer or per-app volume mixer. EQBase was built to fill that gap with a native, modern audio tool that makes basic sound improvements easy while keeping advanced control available for people who need it.

Which are the primary technologies used for building your product?

EQBase's answer:

EQBase is built natively for macOS with Swift, SwiftUI, and Core Audio. It uses a user-space virtual audio driver to process system audio without a kernel extension.
