Red face Silly question time...

Ok, I wouldn't consider myself ignorant, but I keep reading of DAC this and DAC that, and I wonder, what is a "DAC"?

I guess D is for "digital". Maybe I've been in an analogue world too long...?

Digital to Analog Converter

- converts, decodes digital data description of sounds
from CD and DVD
into analog electrical signals,
that can be used feed to sound reproducers like speakers

in normal speaker electrical currents
are converted into physical, mechanical movements
using the electro magnetic force of coils

so are the air pressure changes hopefully in accordance with the electrical power in audio amplifier output
and we can hear these air pressure changes
with our sensors for this = ears
and we call them sound

I love silly questions, they're the best ones.

So it turns out you knew what a DAC was all a long and you've heard plenty of them. Surprise!
Take the Speaker Voltage Test!

Thanks all, and especially to Mr lineup. I couldn't have written a better overview of how we experience digital to analogue conversion and beyond...

I'll never look at a CD player in the same light again
