ucket and throw the water towards the fire. That would have a
quick result, but may waste a lot of water if he missed.
A better alternative would be to have five firemen, all standing a
meter apart. The first would fill the bucket, then pass it to the
second, and on to the third, and so on. Eventually the fifth fireman
would be close enough to accurately douse the fire.
However, the only downfall is that it will take a little longer.
This recording is incredibly accurate, and can simply be “told” to
replay itself when needed. Complicated circuitry, but a very
simple result.
So switch on the Delay (either method) and try playing the Simple
Guitar sound.
Figure 10.5 Delay
This is the whole idea behind a circuit created to reproduce an
electronic Delay. Instead of the signal being passed directly to the
output, it would be sent to a small circuit that took a finite amount
of time to process it. That circuit would pass it on to another
similar circuit with the same processing delay problem. Then on
to another. And another. Finally the signal would be sent to the
output having been delayed by all the previous circuitry.

The GAIA Delay
The GAIA Delay, however, is something quite different. Modern
technology has brought another idea called Digital Sampling.
With Digital Sampling the GAIA can make an exact digital
“recording” of the sound, much like what you hear when you play
a CD or an mp3.
