Blowing air out of your mouth, like blowing out a birthday candle, is just a DC form of talking. (lemmy.world)

Error being blown out of your mouth is similar to DC ( direct current ) and that it's a continuous wave of air with frequency zero. While speaking is like AC ( alternating current), a longitudinal wave that moves back and forth at a variety of frequencies.

I don't get it? What's DC in this context?

DC as in direct current, while AC is alternating current.
