In
digital audio, the objective difference grade (ODG) is calculated by perceptual evaluation of the
audio quality algorithm
In mathematics and computer science, an algorithm () is a finite sequence of rigorous instructions, typically used to solve a class of specific problems or to perform a computation. Algorithms are used as specifications for performing ...
