PRIVACY-FIRST ACOUSTIC NAVIGATION
Not the shortest route.
The calmer route.
RutaCalma turns short, locally processed sound samples into an acoustic comfort layer for pedestrian navigation.
Raw audio is not uploaded or stored. Microphone access requires HTTPS or localhost.
Privacy by design
Microphone → on-device feature extraction → acoustic metadata → map.

Acoustic comfort map
Miraflores pilot zone · demo dataset + your live contributions
CalmModerateLoud
Seeded markers are explicitly labeled Demo dataset. Measurements you capture are labeled Live contribution.
How the MVP works
Listen briefly
A 5-second environmental sample is captured only after user permission.
Analyze locally
Web Audio extracts loudness, variability and spectral features in the browser.
Minimize data
Only acoustic metadata and an approximate location are needed for contribution.
Choose calmer
Route scoring balances walking distance with estimated acoustic exposure.
