Free Tool
Sound Signature Finder
Most people can't name the sound they like - they just know it when they hear it. This tool plays a short royalty-free loop and lets you pick, by ear, between two versions that differ in one thing: bass, mids, treble, reverb, dynamics, even-harmonic warmth, or stereo width. After seven blind rounds it tells you the signature you actually preferred, in plain English, and what to look for in a review.
Tip: use headphones and set a comfortable volume before you start. A/B is level-matched as closely as the browser allows, so judge tone - not loudness.

Round 1 of 7
Switch between the two versions, then choose the one you prefer.
What each control changes
| Dimension | What it is | More of it sounds... |
|---|---|---|
| Bass | Low-shelf lift around 110 Hz | Fuller, weightier, warmer; too much muddies vocals |
| Mids | Peak around 1 kHz | Vocals and guitars step forward; "scooped" mids sound distant |
| Treble | High-shelf lift around 7 kHz | Airier and more detailed; too much gets sharp or sibilant |
| Reverb | Convolution room ambience | Bigger, deeper soundstage; too much smears detail |
| Dynamics | Compression amount | Open and lively (less compression) vs punchy and even (more) |
| Warmth | Even-order (2nd) harmonic distortion | Rounder, "tube-like" richness; the analogue glow people chase |
| Stereo width | Mid/side balance of the stereo image | Wider and more enveloping; too much hollows out the centre, mono collapses it |
FAQ
Sound signature finder FAQ.
What a sound signature is, why the test is blind, where the music comes from, and how to turn your result into a buying decision.
What is a "sound signature"?
A sound signature is the overall tonal character of a piece of gear: how much bass it has, whether the treble is soft or sparkly, how forward the mids sit, how big the soundstage feels, and how it handles dynamics. Two headphones can both be "good" and sound completely different. Knowing the signature you prefer is the single most useful thing when shopping, because it turns a wall of reviews into a short list.
Why is the test blind?
Because labels bias you. The moment you can see which option is "more bass" or "more expensive," your brain starts voting with its expectations instead of your ears. Hiding the labels until the end forces an honest choice. It is the same logic behind our ABX test, applied to preference instead of detection.
Where does the music come from? Is it copyright-free?
All three backing tracks - ambient pads, fingerpicked acoustic, and a lo-fi beat - are synthesised in your browser in real time using the Web Audio API. Nothing is streamed, uploaded, or downloaded, and there is no licensed recording involved, so it is 100% royalty-free. The EQ, reverb, dynamics, warmth, and stereo width are applied live on top, which is why switching between A and B is instant and perfectly time-aligned.
How accurate is it, really?
It is a preference explorer, not a measurement instrument. A and B are level-matched as closely as the browser allows so you judge tone rather than loudness, but your headphones or speakers colour the sound too. Treat the result as a strong hint about the signature you gravitate toward - then confirm it against real reviews and, ideally, a demo.
How do I turn my result into a buying decision?
Your signature maps onto the language reviews already use - warm, bright, neutral, V-shaped, mid-forward. Once you know yours, filter the review archive and the buying guides for gear described that way, and read the verdict for whether it leans the direction you preferred. The result screen links you straight into the matching reviews.
Will it damage my hearing, and does anything leave my device?
A built-in limiter caps the output and A/B is level-matched, but you still control your system volume - start low. Nothing leaves your device: the audio is generated and processed entirely in your browser, with no upload, no account, and no tracking.
