Abstract
Producto de software para optimizar la reproducción de sonido por un sistema de audio. En una realización, el software incluye un motor de ecualización para ajustar independientemente las características de una señal de audio en cada una de múltiples bandas de frecuencia. El software después pasa la señal ajustada a un motor de dinámica que tiene umbrales de irrupción y relajación independientemente ajustables, y ajustes de índice de irrupción y relajación para asignar un límite de excursión del controlador de parlante, que conoce la relación tensión a excursión correspondiente al controlador de parlante. El software después pasa la señal de audio a un motor de ampliación de bajos configurado para incrementar todas las frecuencias graves, por debajo de la frecuencia sub-grave (rolloff de bajo) del controlador del parlante. La señal incrementada se pasa a un motor de dinámica dedicado para frecuencias graves incrementadas, teniendo nuevamente el motor de dinámica umbrales de irrupción y relajación independientemente ajustables, y ajustes de índice de irrupción y relajación para asignar un límite máximo de excursión del controlador de parlante.Software product to optimize sound reproduction by an audio system. In one embodiment, the software includes an equalization engine to independently adjust the characteristics of an audio signal in each of multiple frequency bands. The software then passes the adjusted signal to a dynamics motor that has independently adjustable irruption and relaxation thresholds, and irruption and relaxation index settings to assign an excursion limit of the speaker controller, which knows the voltage to excursion ratio corresponding to the speaker controller The software then passes the audio signal to a bass boost motor configured to increase all bass frequencies, below the sub-bass frequency (bass rolloff) of the speaker controller. The increased signal is passed to a dedicated dynamics motor for increased bass frequencies, the dynamics motor having independently adjustable irruption and relaxation thresholds again, and irruption and relaxation index settings to assign a maximum excursion limit of the speaker controller.
