Decomposing bat echolocation interpulse intervals into acoustic acquisition and proportional behavioural intervals explains hyperbolic call-rate trajectories, terminal buzz update budgets, buzz readiness, and multi-target sonar strobe groups.

BATSY4-PRO is an open-source multichannel ultrasound recorder for field bat bioacoustics, enabling high-quality recordings and localisation with a compact, affordable design.

This paper optimises microphone array geometry for improved localisation accuracy in bioacoustic applications, showing that geometry, not sensor count, primarily determines performance.

This study identifies temporal feasibility constraints that govern wingbeat-call synchrony in echolocating bats, showing how delays and motor dynamics determine when synchrony is possible or breaks down.

RUBAT Studio provides a unified platform for multichannel ultrasonic recording and real-time monitoring, enabling complex acoustic experiments with high sampling rates and compatibility across hardware.

Esperdyne is an open-source, low-cost ultrasound monitoring system for ecological studies, enabling real-time listening, recording, and analysis of bat calls in the field.

This study explains how water-foraging bats regulate call timing using environmental reference echoes, showing geometric interference patterns and call-rate scaling.

This paper introduces Array WAH, a simulation framework for designing microphone arrays to accurately track echolocating bats, showing that tetrahedral and octahedral geometries provide better localisation than planar arrays.

This paper develops a framework to understand how sensory constraints affect swarm cohesion in echolocating bats by modeling temporal and signal dominance limits.

This study shows that oscillating ears in constant-frequency bats enhance echo information by dynamically transforming returning signals, improving temporal contrast and spectral diversity during echolocation.
