redlining

In broadcasting or sound engineering, redlining is when the levels are set too high and the lines on the screen/board are in the red instead of the more desired orange or yellow. Leaving levels at this high level may cause your audio to sound distorted and unpleasant.

Dude, your levels are up too high, you're redlining!

Redline

A set amount of RPMs which your engine can put out before you pretty much blow it up. This is usually where your numbers on your tachometer start turning red, just be sure to keep it out of the red or else $$$$ will be needed. For instance, the redline on my 95 Jeep Grandcherokee is 5,300 RPMS that is exactly where they start turning red, some cars have a rev limiter on them, so due to my rev limiter the engine will not go past 5,300rpms and the engine starts "bouncing" meaning the needle will do the same. I advise you not to try this.

Dude your not supposed to shift while ur racing till you redline it
