Abstract

Las modalidades se refieren a altavoces y circuitos que reflejan sonido de un techo a una ubicación de escucha a una cierta distancia de un altavoz. El sonido reflejado proporciona indicaciones de altura para reproducir objetos de audio que tienen componentes de audio aéreos. El altavoz comprende controladores de disparo ascendente para reflejar el sonido en la superficie superior y representa un altavoz de altura. Un filtro de altura virtual basado en un modelo de audición direccional se aplica a la señal del controlador de disparo ascendente para mejorar la percepción de altura de las señales de audio transmitidas por el altavoz de altura virtual para proporcionar una reproducción óptima del sonido reflejado aéreo. El filtro de altura virtual se puede incorporar como parte de un circuito de cruce que separa la banda completa y envía sonido de alta frecuencia hacia el controlador de disparo ascendente.
