Sound clips

Click on the video clips below to listen to cetacean vocalisations and to view the associated spectrogram. A spectrogram is a time-varying spectral representation (forming an image) that shows how the frequency and amplitude of a signal varies with time. In some cases RainbowClick is used to display the sound files in preference to a spectrogram.

We will add more species and also clips of anthropogenic (man-made) sounds in the near future.

Some of the recordings have been sped up or slowed down to bring them within our own audible range, typically 20 to 20,000Hz.

For clarity it may be preferable to listen using headphones.
