Webnot.Helperplotspectrogram (Hychirp, T, FS, 50) for non-stationary signs such as hyperbolic squeaking, using the STFT is problematic. With the CWT, it can precisely estimate the instant frequencies over the duration of the signal, without worrying about choosing a segment length. The white dot line marks what is known as the cone of influence.
