16 Hz
Optimal modulation rate
Best sustained-attention performance in controlled parametric study.
[3]
Evidence-led focus audio
Sound engineered
for focus.
Amplitude-modulated music, shown in peer-reviewed research to support sustained attention — especially if you have ADHD. Built on published neuroscience, not marketing.

How it works
Three steps, then just work.
Pick your intent
Deep execution, learning retention, or creative exploration. Start with what you need right now.
Choose your sound
Amplitude-modulated tracks engineered for the session type. Not background noise. Purposefully designed audio.
Let it run
The modulation does its job quietly. You stay on the task. That's the whole idea.
Why not Spotify?
General music is designed to be enjoyed.
Unphased is designed to keep you on task.
Not mood music. 16 Hz amplitude modulation that synchronises with your attention networks — documented in peer-reviewed research, largest effect for people who struggle most with focus.
General music
Passive, mood-driven, no attention engineering
Binaural beats
Popular but inconsistent evidence for sustained attention
Unphased
16 Hz amplitude-modulated, peer-reviewed signal
The science
What the research actually says.
d = 3.74
EEG coupling effect
Brain locks onto modulation rhythm vs. control audio — a very large effect.
[3]
g = 0.40
Meta-analytic effect
Moderate pooled effect across 15 studies. Publication bias likely overstates it.

ADHD ↑
Greater benefit for attentional difficulty
Higher ADHD symptom scores correlated with larger gains under 16 Hz modulation.
