Methodology
This page explains how Binaural Beat Machine generates audio — engineering choices, not medical claims. Use stereo headphones.
1. True stereo binaural carriers
Each ear receives a continuous pure-tone (or program-driven) carrier. The beat is the frequency difference between left and right. Speakers collapse that difference; headphones keep L/R isolated so the effect can form.
- Carrier — base tone (typically tens to hundreds of Hz)
- Beat — designed difference (e.g. delta / theta / alpha / beta / gamma ranges as listening targets)
- Master path — stereo mix, meters, gentle limiting to avoid harsh peaks
2. Programs as timed phase timelines
Automated programs are ordered phases: each phase has a start minute, label, and parameter snapshot (carrier, beat, tone level, ambient, optional drum/guide levels). The runner crossfades parameters over several seconds so transitions are not hard cuts.
Free library: 60 programs. Member library: 250 additional sessions (drum / sage / general / combo / journey designs). Guests can play the first 6 free titles in-app.
3. Ambient, DRUM, and GUIDE buses
- Ambient — optional noise layers (e.g. brown / pink / rain-style textures) mixed under the field
- DRUM (Members) — one-shot kit samples scheduled from the beat grid (tempo related to band/divisor), not a free-running drum machine loop
- GUIDE (Members) — phrase banks (Sages + General themes) with gaps between complete lines so binaural field remains primary
4. Build A Program
Users design multi-phase journeys by capturing Console snapshots. Free tier: up to 6 phases / 90 minutes design & run. Members: up to 9 phases / 150 minutes, save to profile / computer, cloud sync on login, and optional WAV export of the built timeline.
5. WAV export (Members)
Offline render of FREQ + ambient, plus DRUM hits and GUIDE phrases when the program or live faders include them. Levels follow the Member’s faders where applied. Full program length (not a short teaser). Prefer a desktop with free disk space — files are large. Limit: 15 exports per week.
6. What we do not claim
- Not a medical device; not a diagnosis, cure, or treatment
- No guaranteed EEG match or clinical outcome
- Individual results vary (volume, sleep debt, expectation, environment)
- Keep levels comfortable; stop if you feel unwell
