How does volume control work in digital devices?
In: Engineering
* There are two ways:
* The first is controlling the amp.
* Sound is analog by nature.
* So every digital audio signal that makes it to your ears is converted to analog at some point.
* When you adjust the “volume” on a device, you are telling the amplifier how much to amplify the signal.
* However, you can also modify the digital version of the signal to have a higher level.
* This is done by simply doing some math with the audio samples.
* So in this scenario, the signal data itself is altered. Then it gets fed into the device that converts it to analog.
