Datei:SSDA Better16bit.png|Still unexpensive solution to get nice 16-bit audio output
</gallery>
The 16-bit output is done by operating two 8-bit outputs together: One will provide an 8-bit signal containing the higher 8-bits and the other one contains the lower 8-bits. If you listen to each of those channels separately, you will hear the usual audio on the upper 8-bit outputs but with noticable 8-bit noise especially on quiet audio parts. On the lower 8-bit you will hear just noise. But when you add this noise (reduced in volume by a factor of 256th done by the resistors) to the higher 8-bits then something magic will happen: The 8-bit noise will vanish (but unfortunately often a lot of noise originating from power supply might still be left).
