Notes

nYou can quickly adjust the frequency range by zooming in and out the frequency axis. Press Ctrl and move the mouse wheel while pointing anywhere on the large spectrogram.

nAdjusting the range of frequencies to be shown in the spectrogram does not filter your signals. To filter signals (for example, to remove audible vocalizations), see Filter the recording.
