La repetición es un elemento clave en la percepción de la estructura musical, la cual se compone de patrones que se repiten en el tiempo (como patrones rítmicos en el acompañamiento musical) y frecuencia (por ejemplo, diferentes notas musicales del mismo instrumento). El sistema auditivo humano muestra una capacidad asombrosa para unir dichos patrones identificando repeticiones dentro de señales acústicas complejas. En este Trabajo Fin de Grado se pretende implementar, utilizando MATLAB, un sistema para la recuperación de patrones repetitivos en tiempo y frecuencia a partir de mezclas de sonidos donde existen sonidos interferentes. A partir de un fragmento musical de entrada, el usuario seleccionará una región tiempo-frecuencia del mismo del cual se desea recuperar los sonidos que son repetitivos en el fragmento musical y eliminar todo sonido no deseado presente en dicha región, se realizará una tarea de denoising operando exclusivamente en la región tiempo-frecuencia seleccionada por el usuario.
Repetition is a key element in the perception of musical structure, which consists of patterns that repeat in time (such as rhythmic patterns in the musical accompaniment) and frequency (such as different musical notes from the same instrument). The auditory human system shows a remarkable ability to identify such patterns by identifying repetitions within complex acoustic signals. In this project, it is intended to implement, using MATLAB, a system for the recovery of repetitive time and frequency patterns from sound mixtures that contain interfering sounds. From an input musical segment, the user will select a time-frequency region in which they wish to recover the repetitive sounds in the musical segment and remove any undesired sound present in that region, a denoising task will be performed exclusively within the user-selected time-frequency region.
