I can't think of a faster way -- wouldn't it just take a few minutes to drag it out to 8 hours? Just drag to the right and hold until you've got 8 hours. Doesn't this work?
The specially crafted white noise will be used in a hospital to cancel out normal background sounds for patients who can't otherwise sleep through the night. It works for them. Many thanks for the tip.
Why not play a recorded politicians speech ? Guaranteed to put anybody to sleep :+
That is a good trick with setting the time - you can also create a segment, copy and paste that a number of times then reselect the whole thing and repeat so you are making bigger segments (which goes faster).
No, it's not easier. I used SonyMLogan's tip and it was done in three milliseconds. All the other tips provided are known and very do-able but what's the point of dragging, cutting and pasting in the 21st century. It seemed so retro. With all the posts I made on this, I could have done it several times over already in the old way but I held out and was rewarded with instant gratification. That's what it's all about.
