Frequently asked questions

For binaural beats and bilateral audio, yes — they rely on your left and right ears receiving different signals. Isochronic tones, monaural beats, 40 Hz stimulation, noise beds and nature layers all work fine on speakers. Vibroacoustic bass is best on a system (or headphones) that can actually reproduce 20-120 Hz.

Rendering starts the moment payment clears. 30-minute sessions typically land within 20 minutes, hour sessions within 30, two-hour sessions within the hour, and a full 8-hour night within 4 hours. The thank-you page shows live progress the whole way.

An email with download links for two files: lossless FLAC (24-bit / 48 kHz — the master itself) and MP3 320 for phones and small players. Both are yours to keep for personal use.

Modern Windows, macOS and iOS play FLAC out of the box; most Linux distros too. If yours does not, install VLC (free, every platform) or foobar2000 on Windows. Full player list on the How to play FLAC page. If you cannot, the MP3 also works everywhere.

Roughly 600 MB per hour for FLAC and 145 MB per hour for MP3. An 8-hour FLAC is close to 5 GB — a stable connection helps.

List prices are in Australian dollars, but you pay in your own currency: Stripe detects your region at checkout and quotes your local equivalent automatically. Any card worldwide works. Your receipt shows exactly what you paid.

The files are purged after the download window, but we keep your order's settings on file: contact us and we'll re-render your session and send a fresh link, free.

Straight answer: published research is active but mixed, and people respond differently. We engineer the stimulation precisely — exact frequencies, clean waveforms, proper stereo handling, calibrated loudness — and we wrap it in music worth hearing on its own. We make no medical claims, and anyone who does deserves your skepticism.

These are audio files at normal listening levels — treat them like any music. That said: don't listen to sleep or deep-relaxation sessions while driving or operating machinery, keep volumes sensible, and if you have epilepsy, a seizure history, a heart device, or are pregnant, check with a health professional first. Stop listening if you feel unwell. See the full wellness disclaimer.

Sessions are licensed for your personal use — listen on any of your devices, forever. Redistribution, resale, or publishing in monetised content isn't included; contact us for anything like that.

Tell us within 14 days: we'll re-render once with adjusted settings for free. If a file is faulty, we replace it or refund you — Australian Consumer Law guarantees always apply. Details on the refunds page.

Because your settings genuinely change the output — the frequencies, layers, musical bed, arrangement and mastering are computed for your exact settings. No two sessions are the same file. That's the product.
