Research · listening test

Help us test sound by ear

About 5 minutes for every 10 pairs.

This is a short listening test. You will hear pairs of sounds.

Each pair is the same sound with one thing changed. We ask what job each sound has. Then we ask which one fits a job better.

There are 31 pairs. Each pair takes about 30 seconds.

The sounds are real drum-machine and sampler one-shots, not made-up ones. We take a real sound and change one thing about it.

Your answers are anonymous. We do not store your name, email, or IP address. Answers save as you go, so even a short visit still helps. You can stop at any time.

What the jobs mean

Are you a producer? (optional)

Where the sounds come from

Every sound starts life as a real one-shot from a freely licensed pack. We shorten a tail, soften a top end, or push a drive, and nothing else.

No music from the research corpus is used here. Those tracks are licensed for study only, so we never republish them or anything cut out of them.
