Deriva.

Deriva is a field-deployable acoustic measurement tool in active development. It is built to study how rooms, systems, and environments change over time through SPL heat mapping, reference-based drift, and coherence visualization.

The studio’s intent for Deriva is to give researchers, engineers, and serious operators a local measurement tool for documenting acoustic behavior over time. Measurement and capture run on the device. Session data can be reviewed, exported, or retained as a record when the work calls for it.

Measurement

Deriva currently combines SPL heat mapping, reference-based drift monitoring, and coherence visualization. The SPL view tracks level behavior over time. The drift view compares current acoustic behavior against a captured reference. The coherence views examine signal relationship and stability across frequency and time.

Deriva runs natively on macOS, with local measurement, local capture, and no required cloud account.

Field deployment

Deriva entered active deployment at the F1 Miami Grand Prix in May 2026, where it ran continuously through race weekend in support of audio and broadcast operations. The deployment marked the instrument’s first sustained run in a high-pressure production environment, providing real production data for evaluating long-duration capture, acoustic history, SPL heat mapping, reference-based drift, and unattended operation.

Availability

Deriva is currently in field deployment with the studio. A wider release is in preparation. Researchers, engineers, consultants, and operators interested in acoustic behavior over time are welcome to make contact.hello@zerqon.org.
