The object of research is preprint processes for the manufacture of audiobooks. The analytical and experimental studies reported here are based on the application of the methodology for devising a simulation model for calculating the complexity of preprint processes in the production of printed books with sound applications. The basic assumption of the study is that the use of simulation will contribute to the improvement of calculations of the complexity of preprint processes for making audiobooks. This cannot be achieved without analyzing the factors influencing the convenience of perception of textual and sound information and establishing the objective function of mutual influence of the text of the publication and audio. A methodology has been proposed for calculating the complexity of the preprint process of making audiobooks based on the developed algorithm of the technological process, mathematical representation of the structural model, as well as its components. It is shown that the process of creating audio accompaniment is affected by the content of printed pages, font design parameters, the selected format of page assembly, and the presence of illustrations. Based on the obtained expert assessments, a hierarchical representation of factors influencing the convenience of information perception is built; the interaction of parameters at different technological stages is described. The dependence of the complexity of the process of making audiobooks on the volume of the book edition in the accounting and publishing sheets, the size and capacity of the font, as well as the speed of sound recording of the printed text, has been established. It is determined that with an increase in font capacity within 200...1000 thousand characters, the calculated labor intensity increases by 5 % to 20 %. The largest limits of changes in the complexity of creating an audio accompaniment are 9 %, at the stage of processing graphic information – 50 %
