 JSON files are the outputs of a custom-made annotation tool [PyAVA](https://gitlab.lis-lab.fr/loic.lehnhoff/PyAVA), were each key is a different whistle contour, and each contour is defined by a list of points represented as time-frequency coordinates.
 
-TETRA's recordings are of lesser quality than icListen hydrophone: 16-bits depth (half of icListen), varying sampling rates and electrostatic buildup (e.g. channel 1 (CR3 hydrophone) in 20220723_102814UTC+2_V12.wav). Therefore, they may demand more processing effort.
+TETRA's recordings may demand more processing effort due to varying sampling rates and noticeable electrostatic buildup on channel 1 in 2022. TETRA's and icListen's recordings can be used for signal detection and analyses, but only TETRA can be used for angle of arrival estimation.
