The important digital transformation that we are witnessing in our society has also had an impact in the cultural sphere. We are currently in a post-digital phase in which we interact daily with emerging products and services.After observing the most significant changes around the world of books and libraries, we stand out as one of the most notorious that of digital audiobooks, in addition to being a very little researched topic, especially in Spain.In the thesis we delve into the factors that determined the growth of the format, especially in the commercial sphere, and we outline the possible reasons for its stagnation of digital audiobooks in documentary environments. To do this, and to have a broad vision of the current situation, we analyze the supply of audiobooks on the market and their distribution models.Using this experience, we proposed a methodology to evaluate audio reading applications. This methodology aims to offer the point of view of the area of information sciences and documentation in a audio project of this nature. From this perspective, we determine the essential quality aspects in any audio-reading application. This methodology will serve as a basis for future research, both in the documentary and commercial fields.
