Sistema digital de compensación de la respuesta en frecuencia del conjunto recinto-altavoz utilizando un filtro adaptativo

The following investigation wants to develop through the use of Digital Signal Processing and the knowledge of the acoustic conditions required in Mixing and Mastering rooms, a program that allows you to get a desired frequency response in the sweet spot from the current conditions of occupation of the room in study. This process is achieved by applying processes of adaptive filters, correction of delays and storage of buffers that allow to capture, analyze and adapt the frequency response as is desired. Different types of adaptive filters are implemented and analyzed as the LMS Standard, LMS Normalized and the LMS Leaky; Also included conclusions about its operation, advantages and disadvantages in order to achieve the objectives of the project by optimizing the computational load. In addition, a test in real time of the program are implemented, allowing adaptation of the frequency response inmediately with the changes of occupation in the room.
