How Does Digital Volume Control Work at David Elsie blog

How Does Digital Volume Control Work. Dithering, by the way, seeks to randomise the digital. Here we are playing a tone with a maximum amplitude of 0dbfs and plotting the spectrum indicating the noise. So let’s look at what signal and noise do for a digital and an analogue volume control. So basically, when you use a digital volume control and lowering the original number to lower the volume you're losing bits in the bargain. There’s a common issue that affects many amplifiers or integrated stereo systems with a digital volume control, where control of the volume on the front of the unit itself is via a physical knob. Digital potentiometers (pots) offer advantages for audio volume (gain) control applications and can replace bulky mechanical. With a 24 bit dac, your digital volume control can reduce the amplitude of this digital error noise by up to 256 times compared with 16 bit! Found in modern audio systems, digital volume controls use digital signals to adjust the volume.
