The Spectrogram Ultrasound Display is designed for use with ultrasound detectors such as those used to capture high-frequency vocalizations of
bats, and communication signals by grasshoppers, rodents or other animals. Ultrasound detectors shift these high frequency sounds down into the audible frequency range and save them as Windows wave file recordings. The
Spectrogram Ultrasound Display is used for analysis of these recordings
and is scaled so that proper measurements of frequency and time can be made directly from the
screen.
