As sound designers, we're often drawn to talking and writing about our latest endeavors in creating new and interesting sounds from scratch. We blog about just such occasions all the time here at Boom Box Post, like when we recorded our own alien vocals or I created the sound of a submarine moving through blood vessels with a contact microphone in my bathtub.
But, it's important to remember that sometimes the most successful sound design isn't born of invention, but instead of perfectly matching just the right sound from the real world.
