Abstract
Ses sinyalinin spektral gösterime dönüştürülmesine yarayan birinci dönüşüm algoritmasına dayanan spektral değerlerin art işlenmesi için, öncelikle ses sinyaline ait bir örnek bloğu dizinini gösteren bir spektral değerlere ait blok dizini sağlanmaktadır. Bundan sonra, spektral değerlere ait blok dizinine ilişkin spektral değerlerin ağırlıklı eklenmesi işlemi art işlenmiş spektral değerlere ait bir blok dizini elde etmek amacıyla gerçekleştirilmektedir; burada bir frekans bandı ve zaman uzunluğu için art işlenmiş spektral değeri hesaplamak amacıyla frekans bandı ve zaman uzunluğu için blok dizinine ait bir spektral değer ve başka bir frekans bandı ve zaman uzunluğu için bir spektral değer kullanılacak şekilde kombinasyon gerçekleştirilmektedir; burada kombinasyon ayrıca ağırlık faktörleri kullanılacak şekilde gerçekleştirilmektedir ki içerisinde birinci dönüşüm algoritmasından farklı olan ikinci dönüşüm algoritması kullanılarak ses sinyalinin spektral bir gösterime dönüştürülmesiyle elde edildikleri için art işlenmiş spektral değerler spektral değerlere yakındır. İleri işlenmiş spektral değerler özellikle sırasıyla ölçeklenebilir bir şifreleyici veya buna ek olarak ölçeklenebilir bir şifre çözücü içerisinde bir fark oluşumu için kullanılmaktadır.
