Abstract

Buluş, ses cihazları için kombine dinamik aralık sıkıştırması ve kılavuzlu kırpma önleme için bir konsept sağlamaktadır. Konsepte göre bir ses bit akışının ve ses bit akışına ilişkin bir metaveri bit akışının dekode edilmesi için bir ses dekoderi, ses bit akışından türetilen bir dekode ses sinyalini almak ve bir ses çıktı sinyalini üretmek için ses sinyalin karakteristiklerini uyarlamak üzere konfigüre edilen bir ses işleme zinciri, burada ses uyarlama zinciri ses çıktı sinyalin bir dinamik aralığını uyarlamak için bir dinamik aralık kontrolü aşaması içeren ve ses çıktı sinyalin kırpılmasını önlemek için bir kılavuzlu kırpma önleme aşaması içeren birçok uyarlama aşamaları içermektedir, ve metaveri bit akışını almak ve metaveri bit akışından dinamik aralık kontrolü kazanımı sekansları ve kılavuzlu kırpma önleme kazanımı sekansları çıkartmak için konfigüre edilen bir metaveri dekoderi içermektedir.
