Humans are born with a musical instrument attached to their face. All they have to do is mush their lips together and blow to make pretty sounds. Germany’s Best Service has released Whistler. A Native Instruments Kontakt library full of real human and bird whistles. I think this is pretty interesting. Why not add a background layer of whistle at the end of a song now and then? Sitting on the Dock of a Bay (iTunes link) by Otis Redding comes to mind.
“With the help of talented whistler Eduardo Tarilonte and a few birds, Best Service has released Whistler (19.99 EUR or approximately $30), a comprehensive library of every type of whistle tone you can imagine. No synths were used to create this library” – gearwire.com
Whistler is about 20 Euros. For more info: www.bestservice.de
