About TestMyAudio

What this site is

TestMyAudio is a small set of in-browser tools for checking that microphones, speakers, headphones, and your hearing are doing what you expect. Everything runs as a single web page. There is nothing to install, no account to create, and no waiting room before a tool becomes usable.

The intent is narrow on purpose: a fast diagnostic stop you can use on any laptop, phone, or borrowed machine when something audio-related is misbehaving. If you are about to join a meeting, record a podcast intro, plug in a new pair of headphones, or wonder whether the high-end of your hearing has changed, this site is built for that minute of your day.

Who it is for

The audience we have in mind ranges across:

• Remote workers and students troubleshooting calls before they start.
• Podcasters and streamers verifying their input chain.
• Musicians and producers checking system latency or stereo channels.
• People comparing headphones, earbuds, or external speakers.
• Curious readers running a casual frequency-range or sound-level test.

None of the tools require technical background. The interface is designed so that you can press one button and learn something useful within a few seconds.

What we offer

The home page hosts a suite of compact tools, each focused on one problem:

Each tool is paired with short, on-page guidance that explains what a normal result looks like and where to go next if a result is off. Longer explainers — for example, microphone troubleshooting, audio latency, decibel levels, and hearing-range results — live alongside the tools they relate to.

How the tests work

The tools are powered by browser APIs that are now standard across Chrome, Firefox, Safari, and Edge:

• Web Audio API for real-time analysis, oscillators, and frequency sweeps.
• MediaRecorder API for the short voice recordings used in the playback tool.
• getUserMedia for capturing microphone input under your explicit permission.

The site is plain HTML, CSS, and JavaScript — no framework, no build step, no server-side audio handling. That makes it small enough to load over a slow connection and simple enough that the privacy story is self-evident: there is no upload step because there is nothing on the other side to receive it.

Editorial approach

Content is written and reviewed by people who use these tools day-to-day, with an eye toward being practical and accurate rather than exhaustive. We intentionally avoid:

• Manufacturer-specific recommendations or affiliate-driven gear lists.
• Promises of clinical or professional accuracy where the underlying browser hardware cannot deliver it.
• Filler word counts. Pages exist when they answer a real question we've heard from readers.

Pages are reviewed periodically and re-dated when material changes are made. If something on the site looks wrong or out of date, the contact page is the fastest way to flag it.

What the tools cannot tell you

Browser-based audio has real limits. The decibel meter reads relative loudness from an uncalibrated microphone — useful for comparing two rooms, not for occupational-safety measurements. The hearing test plays tones at unknown absolute levels through unknown hardware, so it is a rough screen, not an audiogram. The latency number includes whatever the operating system, drivers, and audio stack add on top of the browser.

For anything that needs a calibrated instrument or a clinical opinion, treat the on-site result as a hint and follow up with the appropriate professional or measurement device. Our disclaimer page spells this out in more detail.

Privacy stance

Audio analysis runs locally. Recordings created with the playback tool live only in the browser tab and are gone the moment you close it. The site itself uses standard analytics and advertising vendors to fund hosting, and you can review or change those choices through the consent banner. The full breakdown is on the privacy page and the cookies page.
