The development of digital competencies of students is currently one of the main pedagogical tasks. The solution of this task is possible by paying attention to issues related to the skills of students to create their own digital content, for example, multimedia, combining various types of information (text, graphics, video and audio). The article provides a brief analysis of the content of teaching issues related to the study of digital sound processing technologies in a school informatics course. Taking into account the relevance of this issue, a thematic module "Digital Sound" is proposed, the content of which does not require binding to specific software. When studying the module, the emphasis is on mastering specific technologies for processing sound information. The module can be implemented as an optional course for students in 7–9th grades and/or as an elective course for students in 10–11th grades. At the same time, particular blocks of the module can be used at various stages of teaching informatics at school
