Abstract
The article focuses on the type of discrete orthogonal transformations, which is the most a suitable for high quality and efficiency of digital audio signals compression. The author describes the requirements for highly efficient discrete orthogonal transformations and analysis widely spread types of transformations basing on the mentioned requirements.
