Internal operating voltages in electronic devices continue to decrease, but input-source voltages don't change. As the difference between input and output voltages increases, so does the improvement ...

Op amps are voltage-amplifying devices designed to be used with external feedback components—resistors and capacitors—that are situated between their output and input terminals.

AMD’s Noise Suppression tool is its answer to NVIDIA Broadcast It can block background noise for both input and output devices.
