acoust IQ live builds on acoust IQ pro to enable web-based remote control of measurements. A local operator positions an iPhone or iPad with a Class 1 microphone; an expert starts/stops recordings, sets markers, and monitors level time histories in real time via a browser—from next door or across the globe. The preview stream is compressed so that low bandwidth is sufficient; raw data and metadata are synchronized asynchronously to the cloud for full-resolution analysis. Multiple devices can be controlled in parallel; alignment uses GPS timestamps in the millisecond range (not phase-synchronous). All metadata (GPS, timestamps, photos, notes) remain linked to the datasets. The interface supports multi-language operation and is designed so that non-expert on-site staff can assist while remote specialists supervise and execute the measurement.
