An honest comparison
Particle & Brain.fm
Functional music engineered to drive focus.
Brain.fm makes functional music backed by the strongest scientific paper trail in the category: patented amplitude modulation, research funded by the U.S. National Science Foundation, peer-reviewed studies. If you want focus music with published evidence behind it, Brain.fm is the benchmark. This page is about a different question: which theory of sound fits the way you work.
What Brain.fm does brilliantly
A real research program
Brain.fm’s technology was developed with university researchers, funded in part by the National Science Foundation, and tested in peer-reviewed studies — including published work on attention. In a category full of vague science claims, they did the work.
Engineered, not curated
Their patented amplitude modulation is designed to engage the brain’s attention networks. This isn’t a playlist with a marketing layer — it is music built as a tool, from the waveform up.
Music that pushes
If you work best with energy driving you forward — headphones on, music carrying you through the session — Brain.fm is built for exactly that.
Where Particle is different
Brain.fm and Particle hold opposite theories of focus sound. Brain.fm engineers stimulation: music designed to actively steer your brain toward attention. Particle designs restraint: sound built to disappear, because we believe deep work needs less input, not better input.
Every Particle soundscape follows constraints we publish openly — nothing above 1,200 Hz on melodic content, no white noise, attacks never sharper than 10 milliseconds, patterns that are mostly silence. We compete with silence, and we say so. If silence is working for you, use silence.
And sound is only one layer. Particle is the room where the work happens: a timer that counts up, a planner mapped to your energy, a quiet record of everything you’ve made. Brain.fm plays while you work somewhere else. Particle is the somewhere else.
The honest decision
Choose Brain.fm if
- —
You want music that actively drives you forward, not ambience that recedes.
- —
Published, peer-reviewed evidence behind your focus music matters to you.
- —
You already have a place for your work — you just want the audio engine.
Choose Particle if
- —
You want sound that disappears so the work can take over.
- —
You want the whole loop — capture, plan, focus, reflect — in one quiet place.

Questions
Is Particle’s sound scientifically backed like Brain.fm’s?
Differently. Brain.fm runs clinical studies on its own music; we don’t. Particle’s sound follows constraints derived from published psychoacoustics research — frequency ranges, attack times, silence ratios — and we publish every constraint on our science page so you can check the reasoning yourself.
Can I listen to Brain.fm while working in Particle?
Yes. Particle’s timer, planner, and reflection don’t care where your sound comes from. Some people use exactly that combination.
Is Particle free?
The free tier is free forever, with no credit card required. That includes generative soundscapes and unlimited Particle Radio.
