Did You Know?

That the sound that Transformers make when they transform, commonly represented as the onomatopoeia, "chee cha cheh choh choo" (or "choo choh cheh cha chee" if transforming from vehicle to robot mode) begins as an 8 hz pulse repeated five times for 0.7 seconds each repeat whose pitch can be represented by the absolute value of a declining sine wave, with each zero-to-zero arc of the wave representing one of five cycles of the repetition. The actual value of the sine wave can be modified by factor N which is multiplied into the X value but divided into the Y value, which means that although the actual pitch is largely indefinite, in analog terms when the transform pitch is higher the length of each pulse is shorter, and conversely when the pitch is lower the length of each pulse is longer.

Well now you know. Dun say I never tell you.
