Estudio de un códec de compresión de audio para mejorar la calidad de servicio de sonidos estetoscópicos sobre una red IP

Abstract

The present work will serve as reference for future research that seded to the analysis of sounds transmitted in links, both guided or noguiados, being able to serve as basis of the procedure to be followed in case that they would like to carry out investigations similar to this one. The scheme shown in Annex A generally presents the application on which the audio compressor will be used. Once the compression codec is selected for this type of sounds, the technical specifications that the telemedicine network may have for the transmission protocols can be set. As this project already defines a codec recommended for the transmission of stethoscopic sounds, it is possible to implement a devideoconference system that uses a standard that includes the selected codec, allowing the project to expand into several types of interfaces. Carried out this study involved the collection of eighteen digital sound files in both cardiac and respiratory formats.
