Synced to what you hear

Haptic motors have startup latency — without compensation, vibration fires before the sound reaches your ears. The library profiles this window on every play event and gates the haptic chain until the motors have fully spun up.

Fully algorithmic

Hand-authored haptics are more precise — but time-consuming to write. This derives them directly from the audio. Not perfect, but instant.
