美國公司Aquasonic Acoustics的老闆費希爾(Mark Fischer),將海洋動物和雀鳥發出的聲音頻率,用電腦轉化成圖像,製作出萬花筒般的美麗圖案。他強調這些圖案沒有人工修飾,完全純天然。

紅色代表低頻率聲音、藍和綠是中頻頻,紫色是最高頻率。


Sounds of our seas revealed - and they look a lot like the view through a kaleidoscope

These psychedelic symbols are not the snoozing graphics on a laptop - they are the sounds of our oceans' giants, and even garden birds.

Mark Fischer, the owner of Aquasonic Acoustics, began takes whale songs and transforming them into beautiful images.

The 51-year-old converted the voices of the 100-ton mammals into 'wavelets' and then coloured them in with imaging software.

He also uses the technique to capture the melodies of humpback whales, dolphins and birds.

Like a flower: An image of White beaked dolphin (Lagenorhynchus albirostris) sounds  白吻海豚聲波


Plasma ball-esque: The pattern made by the sound of the False killer whale  偽虎鯨的聲波


Jagged: The sounds of the Chipping sparrow (Spizella passerina) produce this blue-green sharp-looking image  北美麻雀的聲波


Five-petalled: Another song of the white beaked dolphin creates this blue flower graph  另一個白吻海豚的聲波

'I do not cut-and-paste or create any symmetry,' said the computer programmer. 'The sound of the whale or dolphin used is represented as honestly as it can be done.'
His software converts the frequency of each sound frame into the colours of the rainbow.

Reds represent low frequency, greens and blues medium, and violets the highest.

Mr Fischer started capturing the sounds in 2001 after an inspiring trip with a whale researcher.

Subsequent reading on the subject showed it 'hadn't moved on in 50 years' and so he decided to revisit it with more advanced technology.


Burst: This graph shows the familiar chirping sound of crickets  蟋蟀的聲波


Pulsing: Here another graph visualises the common insect's much-loved sound  常見昆蟲的聲波


Low frequency: The deep song of the Northern minke whale (Balaenoptera acutorostrata) makes this warm looking image like the flames from a gas cooker  小須鯨的聲波


High-pitched now: Another graph of the songs of the Northern minke whale, this time of higher frequencies  小須鯨高頻率的聲波


Snowflake: This is a third sound from the same species visualised  同樣是小須鯨的聲波


Curves: Another graph of White beaked dolphin song  白吻海豚歌唱聲波


Spirograph? This image of Atlantic spotted dolphin song looks as if it was made with the children's art toy  大西洋斑點海豚聲波


Psychedelic: This graph shows the song of an unidentified bird  某種鳥的聲波


They see me rolling: Humpback whale (Megaptera novaeangliae) song looks like this  座頭鯨的聲波


Deep reds: Another visualisation of humpback whale song  另一個座頭鯨的聲波

'Practically the only thing you could find in the published literature was black-and-white sonograms, and typically low resolution at that,' he added.

'As a computer programmer by trade, I knew better could be done.'

The Californian said the images were well received by the public - but only aesthetically.

'Rarely are they interested in how the images are made, what kind of mathematics is behind the image or even what species made the sound,' he added.


Going green: Another graph shows the song of the false killer whale  另一個偽虎鯨的聲波


Minimalist: The Eastern screech owl (Megascops asio) creates this image like the spokes of bicycle wheel  東美角鴞的聲波


Pretty: A image of Northern cardinal (Cardinalis cardinalis) song converted by wavelet graph  北美紅雀發出的聲波

Mr Fischer said the most striking calls he has recorded have been made by the vermiculated screech-owl and other tropical birds of Costa Rica.

He added: 'I have also worked with the sounds of insects, and, while interesting, they do not show the structure and complexity of birds, whales and dolphins.'

Mr Fischer said he hopes his work will highlight the importance of sound to whales and dolphins and the amount of sound pollution being emitted by commercial ships.

看起來像是夢幻之旅,奇特又華麗,謝謝版主的分享。
音頻所產生出來的圖案,真的是千變萬化,且令人驚嘆。
