Hi, I am currently wanting to record rat vocalisations and analyze them with Audacity, did you figure it out how? My team and I are clueless
Rat vocalizations extend into ultrasound, apparently up to ~100kHz …
You will need special microphones, pre-amps, & A/D converters to record 100kHz audio.
(As normal audio equipment is only designed to operate up to ~20kHz)
