CPC464 designed background noise

[rst123]

Hello

There is that interesting background thinking noise the cpc464 comes with and what makes the cpc somehow special.
An explanation was given in the magazine AmstradComputerUser02-1084.pdf on page 36.

I still have questions:

* How is that implemented technically?
* can this be amplified a little more?
* Are there emulators adressing this thinking sound?

Thanks

Hi rst123,
           still laughing at the "How is it implemented question"!! It's not "implemented" , it's a side-effect of the crap amplifier design, which is neither isolated nor screened.
