Abstract

Способ манипулирования сигналом сложной формы путем анализа частот гармоник парциальных тонов как движущихся целей с течением времени как по амплитуде, так и по частоте, и настройки этих движущихся целей с помощью модификаторов перемещения как по амплитуде, так и по частоте. Манипуляция частотами гармоник и синтез частот гармоник основывается на порядке гармоники. Модификаторы перемещаются по мере перемещения частот на основании порядка гармоники. Преобразование гармоники с использованием порядка состоит в модификации формы сигнала одного источника в соответствии с формой сигнала второго или целевого источника. С помощью выделения гармоник и других парциальных тонов идентифицируется каждая из частот и ее взаимосвязь с соседними частотами, а также фиксированными или подвижными пороговыми значениями и выполняется соответствующая регулировка. Кроме того, описана интерполяция как одна из моделей, имитирующих натуральные гармоники.Отчет о международном поиске был опубликован 2000.06.22.
