Bat Calls
A collection of bat calls from various sites and projects.
ಬಾವಲಿಗಳ ಕೂಗುಗಳ ಸಂಪಾದನೆ. ವಿವಿಧ ಪ್ರದೇಶಗಳಿಂದ ಸಂಗ್ರಹಿಸಿದ ಅನೇಕ ಪ್ರಭೇಧಗಳ ಉದಾಹರಣೆಗಳು
The spectrograms are made with 1024 samples-long windows with 50% overlap at Fs/10 resolution.
The audible sound is resampled at Fs/8 .
ಬಾವಲಿಗಳ ಕೂಗುಗಳು ಮಾನವ ಆಲಿಕೆಯ ಆವರ್ತನೆಯ ಮೇಲ್ಮಟ್ಟದಲ್ಲಿ ಇರುವುದರಿಂದ, ದಾಖಲಿತ ಶಬ್ದಗಳನ್ನು ೧/೮ ಗತಿಗೆ ಪರಿವರ್ತಿಸಿ ಪ್ರಸ್ತುತಪಡಿಸಲಾಗಿದೆ.
#19fe17915
Location: Lohghad Fort, [18°42′32″N 73°28′36″E]
Species: Rhinolopus beddomei Lesser woolly horseshoe bat
Device/@: Ultramic 384k@384 kHz
Description: R. beddomei individual recorded stationarily. Resampling factor 8. View Image
Due to absence of relative motion, the call frequencies are constat at ca. 43 kHz

#19fe15833
Location: Lohghad Fort, [18°42′32″N 73°28′36″E]
Species: Rhinolopus sp.
Device/@: Ultramic 384K@ 384kHz
Description: Recorded on the top of the fort, in a small cave with actively flying group of Rhinolopus sp. The S/N ratio is rather dismal, however the spectrogram reveals an interesting observation. Also, most of the individuals in that colony had prominent a yellow-orange coloration on their noseleaves. The cause of this was indeterminate. View Image
The audio is resampled at 24kHz, however, due to the high frequency of the echolocation calls at close to 100kHz, the calls are close to 6kHz and might feel uncomfortable to an average adult listener.
Multiple individuals echolocating while circling around the a small cave.

Description: A field recording made with an array of custom microphones.
