The object of research. Process of phonograms restoration and recovery are described. Investigated problem. Differences between some methods of quality control of phonograms during and after their restoration and recovery were investigated. The main scientific results. An instrumental method for objective assessment of the quality of phonograms is proposed, based on a non-intrusive model with parametric modeling of the phonogram signal to assess the effect of an artifact on a phonogram. The area of practical use of the research results. The results of the operational control of objective quality indicators of a real sound signal using virtual measuring instruments built into the software for working with sound are considered. An innovative technological product: a technology for assessing the quality of phonograms in the process of restoration and recovery (R&R), which makes it possible to objectively assess the quality of phonograms, taking into account artifacts of phonograms caused by the method of recording phonograms, the conditions of their storage, etc. enough high quality restored audio content. Scope of application of the innovative technological product: studio of restoration and recovery of sound phonograms on analog media, recording studios, technological processes of conversion and processing of sound programs, archives of radio and television recordings.
