Isochronic tones are the simplest of the three entrainment methods on this site. A single tone is switched sharply on and off at a steady rate equal to the target brainwave frequency. For a 10 Hz alpha target, the tone pulses ten times per second. There's no second frequency involved and no stereo requirement, which is why many people find isochronic tones the most immediately noticeable of the three.
That sharp, unambiguous pulse is the tradeoff too. Some listeners find it more intrusive or less pleasant to sit with than the smoother interference pattern of monaural beats or the subtler perceptual effect of binaural beats. Worth trying all three and noticing which one you actually want to keep listening to.
Research on brainwave entrainment shows modest, inconsistent effects. Some people notice clear benefits for relaxation and focus; others notice little. Treat it as one tool among many, not a guaranteed fix. If you have epilepsy or a seizure disorder, consult your doctor before use.
No headphones, no problem
One tone, gated on and off, plays exactly the same through any speaker. If you want something to just switch on and get going, this is the simplest of the three.
If you want to actually feel it
The pulse here is sharp and obvious rather than a subtle blend, so it's usually the easiest of the three to notice, especially if binaural or monaural beats have felt too faint to you.
Pick by what you're after, not a number
Presets are organised by what they're for, focus, sleep, calm, so you don't need to know anything about frequencies to find the right one.
Worth knowing before you dive in
The sharp, rhythmic pulse here is the one entrainment style most often flagged for caution, so check with a doctor first if you have epilepsy or a seizure disorder.
