When you turn down or up the volume on devices with either a wheel or button, what actually happens that allows it to sound quieter or louder?
In: Technology
Nowadays the wheel or buttons generate pulses that control a computer that controls the D/A converter that controls the volume of the signal. To get increased dynamics, there can be one D/A converter for the volume and one (much more high resolution) for the signal, multiplied to get the end result, but it’s not a given. Also, the equalizer is completely digital, using digital (calculated) filters.
