The blue rectangles represent ON bits and the white rectangles represent OFF bits (click the picture to expand it). The red line is the resulting music in the form of a sine wave. See how the red sine wave is going up whenever there's a bunch of blue rectangles, and down when there's lots of blank ones? That's it. That's all you need to know to understand Single-bit Audio (DSD).
Remember there are only two kinds of bits: ON and OFF. An ON bit simply means there's voltage present - just like you had connected a battery between the plus and minus terminals of your loudspeaker. An OFF bit has no voltage present, it's just an empty space, as if you removed the battery from your your loudspeaker. Connect a battery across your loudspeaker and the driver will jump forward and move the air. Remove the battery and the loudspeaker driver returns to its resting position.
If you were able to connect and disconnect your battery from the loudspeaker 2.8 million times a second, you'd probably get a free Guinness beer and a place in the record book of the same name. But if you could ..... then you could duplicate what's in the picture and sound would come out. Music would be there if you followed the right pattern to match the music.
And that's Single-bit Audio. Now, don't forget what I asked you to cram into your addled brain. You're going to need that important piece of useless information tomorrow. Now, where's that ruler of mine ......
