Re: [apple-iphone] Scrubbing
> It sounds like it's cleaning something up but what it really does is fast forward/reverse. Very useful if you're listening to spoken-word stuff & want to go back over something.
FYI: origin of the term "scrubbing"
This comes from the days of audio tape, when fast forward or fast rewind lifted the tape off of the tape heads, but on some machines you could keep the tape running across the heads, so you could listen to the super-speed audio to better estimate when to stop the fast movement and return to normal listening.
The down-side was that the tape abraded (scrubbed) the heads.
