Abstract

Mevcut buluş, doğrusal tahmin katsayıları (LPC) içeren enkode bir ses bilgisine dayanarak bir dekode ses bilgisinin üretilmesi için bir ses dekoderi, ilgili bir yöntem, bu tür bir yöntemin uygulanması için ilgili bir bilgisayar programı ve bu tür ses sinyalin depolayan bir depolama ortamı için bir ses sinyali ile ilgilidir, burada ses sinyali bu tür bir yöntem ile işlenmektedir. Ses dekoderi eğik bir bilgi elde etmek için bir çerçevenin doğrusal tahmin katsayıları kullanarak bir gürültünün eğikliğini uyarlamak üzere konfigüre edilen bir eğim uyarlayıcı ve eğim hesaplayıcı tarafından elde edilen eğim bilgisine dayanarak mevcut çerçeveye gürültü eklemek için konfigüre edilen bir gürültü ekleyici içermektedir. Buluşa göre diğer bir ses dekoderi bir gürültü seviyesi bilgisi elde etmek için en az bir önceki çerçevenin doğrusal bir tahmin katsayısını kullanarak mevcut bir çerçeve için bir gürültü seviyesini tahmin etmek üzere konfigüre edilen bir gürültü seviyesi kestirici içermektedir ve gürültü seviyesi kestirici tarafından sağlanan gürültü seviyesi bilgisine dayanarak mevcut çerçeveye bir gürültü eklemek üzere konfigüre edilen bir gürültü ekleyici önermektedir. Böylece, bit akışındaki arka plan gürültüsüne ilişkin yan bilgi çıkartılabilmektedir.
