Our technology

Passive acoustics and AI dedicated to coral reefs assessment.

Our solution breaks with current monitoring methods by combining the latest passive acoustic technologies, Digital Signal Processing (DSP), and AI algorithms.

  • Continuous recording over several years
  • Standardised data for easy comparisons among sites and over time
  • Non-intrusive monitoring with no effect on wildlife behavior
