What a 4Hz binaural spread means
The 4Hz preset uses 200Hz and 204Hz tones in separate headphone channels. This is a difference between audible tones, not a standalone 4Hz sound or a measurement of brain activity.
4Hz Binaural Beats
Compare left and right tones with a 4 Hz difference. Use stereo headphones.
How to audition 4Hz correctly
Use headphones so each ear receives its own tone. Hzvibe opens this preset with a 200Hz base frequency, but you can raise or lower that anchor after launch without losing the 4Hz offset.
Which delta to compare next
Try 4Hz against 2Hz and 6Hz to hear how the inner beat tightens. Keep the same headphones and volume so the contrast comes from the delta itself, not from other variables.

Questions
Do 4Hz binaural beats require headphones?
Yes. Binaural beats depend on each ear receiving a different tone, so headphones are required for the 4Hz effect to register as intended.
Why does Hzvibe start this preset at 200Hz?
Using the same 200Hz starting tone across presets lets you compare their frequency differences. You can change the base frequency and lower the volume to suit your listening preference.
Can I change the base tone after opening the 4Hz preset?
Yes. The preset loads with a 200Hz base for consistency, but the live generator lets you change the anchor while preserving the 4Hz spread.
