About Audio Test

A small product built around practical listening checks.

Audio Test started as a simple way to verify channels and sweep frequency response on fresh headphones without downloading bulky desktop software.

What we optimize for

The core idea is straightforward: useful tests, clear instructions, and a footprint light enough for static hosting on very small infrastructure. If a feature cannot run on the client, we do not add it.

That keeps page loads fast, reduces operational cost, and makes the project easy to self-host behind nginx or Caddy.

Each tool is intentionally narrow. Instead of trying to become a full DAW, we focus on the quick checks people actually repeat.

Who uses it

Shoppers use Audio Test before keeping a new pair of headphones. Producers use it as a quick sanity check between sessions. Support teams use it to walk customers through channel, phase, or balance issues without asking them to install anything.
