SoundTrack · how it works
Your Big Five profile, measured by how you react to sound.
Generic personality tests ask you to rate yourself, so they inherit every bias in how you see yourself in that moment. SoundTrack works differently. It reads how you respond to sound, turns that into your Acoustic Genome, and maps it to the Big Five, the established standard in personality science.
Why sound, not a questionnaire
The most honest answer is a reaction.
Most personality tests are the same stale format: a long questionnaire you rate yourself on. That invites bias, mood, and the version of yourself you want to project. SoundTrack reads a reaction you can't curate instead.
01
Self-ratings bend to bias
Rate-yourself questions bend to your mood and self-image. How you respond to each clip is far steadier.
02
Preference, not performance
The clips you rate highly, and the ones you don't, are captured before any goals or personality questions are asked.
03
Grounded in the Big Five
Every result maps to OCEAN, backed by decades of peer-reviewed validation, not a made-up set of types.
How your ratings become a profile
Your ratings, read as a pattern.
You listen to a series of short clips and rate how each one lands for you. Across the whole set, those ratings form a pattern. We look at the sound features you gravitate toward and away from, and translate that pattern into Big Five signal.
A short sound clip plays, sometimes familiar, sometimes not.
You rate how much the clip appeals to you, one clip at a time.
Across all your ratings, the sound features you favor translate into trait signal.
The building blocks
Every example is composed from the elements that shape how sound lands in the body.
SoundTrack treats sound as a controlled signal, listening across many dimensions, never relying on a single preference or genre label.

Research foundation
Grounded in music psychology, not adapted from a quiz.
Our work draws on decades of peer-reviewed research into music perception, emotion, and personality, including the contributions of Drs. David Greenberg and Jason Rentfrow at the University of Cambridge.
