Akekee (Loxops caeruleirostris) bird song,wavelet graph. This image was produced by converting the frequencies of sounds made by the Akekee bird,a species native to Hawai'i,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 rectangular graph but wavelet graphs can also be in polar (circular) form. Image created by Mark Fischer from Aguasonic Acoustics,USA.<br>Restrictions: | |
