Thanks haha, that makes a lot of sense actually! I googled impedance and it kinda blew my mind...it's nice for an explanation!

lower the volume

in the older analog audio systems the volume knob is a potentiometer (like a guitar's volume knob for example), which is a variable resistor. adding just a resistor will set the volume lower to a specific level, exactly as if you turned the pot there and left it forever.

people make audio resistors, but they're for loudspeaker systems and thats overkill. so, no need to worry with those, if you find them in your googling....

edit: ie, an audio signal is an electric signal, so with a resistor you have the audible effect of lowered volume

it would technically change the impedance, unless i missed something.

Just volume.

It wouldn't change the audio quality or sound at all?

I think that they will lower the volume

So, I really don't know very much about electronics, just very basic stuff, so I'm sorry if this is actually a really easy question, but what would happen if you soldered resistors to the left and right audio solder points on the PCB, then to wires, then to a jack? What would you hear?

Thanks
