HOW IT'S MADE · TRANSPARENCY
What's actually in your headphones.
Every AmberRoom session is built from up to four layers. We're transparent about which are live audio, which are paywalled to Pro, and which are still being built. No marketing-speak.
LAYER 03 · LIVE

Frequency therapy
Two pure tones in your ears, slightly detuned, plus a noise floor (brown / pink / white). The only layer actually generating audio today. Mathematically perfect, runs client-side via Web Audio API, no licensing or vendor cost.
LAYER 01 · LIVE

Instrument bed
Tibetan and crystal singing bowls via modal synthesis with convolution reverb. $0 cost, runs client-side, ships unlimited variation. Real licensed samples are the planned upgrade once Pro revenue justifies the spend.
LAYER 02 · BUILT · ENV-GATED

Ambient pad
AI-generated drone via Stable Audio API. Endpoint, disk cache, daily budget guard, four-variant rotation, and crossfade loop are all wired. Set STABLE_AUDIO_API_KEY and Layer 02 flips LIVE — no other change required.

Recipe engine
How an intent (sleep, anxiety, grief…) becomes a SessionRecipe — frequency targets, noise color, BPM, instrument selection, pacing curve. The research-grounded layer that ties everything together.
