Description
Killer whale (Orcinus orca) sounds, wavelet graph. This image was produced by converting the frequencies of sounds made by a killer whale into a graph using a mathematical process known as wavelets. Wavelets reveal structure and detail that are not always visible in standard graphs of frequency over time (known as a spectrogram). This image has been plotted as a polar coordinate (circular) graph but wavelet graphs can also be in rectangular form. Killer whale vocalisations contain a wide variety of high frequency clicks, whistles and cries. These sounds are used for echolocation and communication and can be recorded using underwater hydrophones. Image created by Mark Fischer from Aguasonic Acoustics, USA.
