Questions & Answers

As answered by people managing Resend 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.
