Scope note:

A measure of digital resolution as determined by the number of bits used to render each pixel or sample. Higher bit depths indicate a higher tonal range or fidelity. Bit depth for color defines the amount of color available to each of the pixels in digital image processing and display. This is derived from the number of bits used to define color within a digital image as determined by its file format. Audio bit depth is defined by the amount of bits in a sample in digital audio, which directly corresponds to the resolution of the sample and the dynamic range of the resulting sound produced or recorded.
