Estimados,

En esta oportunidad tenemos el agrado de invitarlos a las Jornadas de Audio, Sonido y Acústica UNTREF del presente año, que se desarrollarán los días 13, 14, 15 y 16 de septiembre en la Sede Caseros II de la Universidad Nacional de Tres de Febrero. Las Jornadas contarán con la presentación de invitados especiales de diversas ramas que abarcan el interés de nuestra carrera, en un formato extenso de disertación. También se presentarán trabajos realizados en el marco de las materias de la carrera Ingeniería de Sonido.

Invitamos a todo aquel interesado en presentar trabajos de investigación, desarrollo de tesis y/o desarrollos profesionales a ser partícipe del evento, enviando el resumen (o abstract) del trabajo a [email protected]. La fecha límite para entrega de resúmenes será el 1º de agosto del presente año.

A todos los interesados en asistir a las Jornadas, les pedimos completar el siguiente formulario con sus datos para poder realizar una óptima organización del evento: https://goo.gl/NLldEz.

Les enviamos un cordial saludo, y esperamos verlos en las Jornadas de Audio, Sonido y Acústica!

Atentamente,
Ingeniería de Sonido

Este minicurso se dictará el día 12/9 a las 11:40 hs

Practical Application of Autocorrelation Function (ACF) Analysis

Lecturer: Dr. Shin-ichi SATO

Aim: Autocorrelation function (ACF), which had been used in the mathematical study, is the signal analysis to measure the similarity between a signal and a delay version of itself, looking for self-similarity in time. Since Licklider proposed the idea of “autocorrelator” in human auditory system in 1951, the ACF analysis has been used for the speech analyses to extract the fundamental frequency of the spoken words, and then used for the studies of pitch perception model. The systematic investigation regarding the preferred sound field in concert halls by Ando is an unique application of the ACF analysis to music signals to find the relationship between the subjective and objective evaluations of the sound fields. Recently, the ACF analyses are utilized to characterize the music, speech and noise signals, and the relationship with their subjective evaluations has been investigated. Not only the continuous signals like music, speech, mechanical and the environmental noises, but also the impulsive and the low-frequency sound have been analyzed by the ACF. In this course, the above historical review of the ACF studies is given first, and the useful results of the analysis are introduced with the sound demonstrations.
