Many measurement devices outside this section may be used or at least become part of an identification process. For identification and content concerning chemical substances, see also Analytical chemistry, List of chemical analysis methods, and List of materials analysis methods.
The original bat calls are digitised and the zero crossing points used to produce a data stream which is recorded on a memory card. There are sophisticated timing and trigger controls and the device can be set to respond to bat calls, so that many hours of recording are available in unmanned situations.
This can be used to estimate the speed of a flying bat or to identify bats which are echolocating while roosting. A bat call from a bat approaching or departing at 6.8 metres per second (15 mph) calling at 50 kHz will typically show a doppler shift of +- 1 kHz and pro rats. This can cause uncertainty with some species such as Pipistrelles.

The MLB's bat-tracking data shows that Shohei Ohtani's swing generates the most bat speed for the Dodgers, while Mookie Betts' swing squares up the most and Freddie Freeman's swing is the shortest.
The species has been measured at a ground speed of 160 km/h (99 mph), measured by an aircraft tracking device. [27] The measurement methodology did not simultaneously record wind speed and ground speed, so the observations could have been affected by strong local gusts, and the bat's maximum air speed remains uncertain. [28]
Provides a comprehensive tool for analyzing and comparing high-resolution full-spectrum sonogram of bat echolocation calls recorded from time-expansion bat detectors. Sound Analysis Pro 2011 [9] GPL v2: Windows: Performs automated recording and analysis of animal vocalization. It can record, analyze and manage sound data over prolonged periods.
