Into the Zone — Isochronic Tone to Get You Focused (then fades to silence)

This isn't a focus channel either. I built this to get myself into deep work, and I am sharing it in case it helps you too. It is a soft pulsing tone, no noise bed. It starts around 10 Hz to settle a scattered mind, then rises to 15 Hz over the next few minutes, the calm, alert band that suits concentrated work without the wired, anxious edge of pushing higher. Once it has you there, it fades out and leaves you in silence to work uninterrupted. It is a primer, not a timer. No bell, no break, no pomodoro. Start it as you sit down, let it bring you up to speed, then forget it is there. No claims or science lecture. This is simply what works for me. I hope you find it useful.
