Abstract

Birden fazla kanala haiz olan bir ses sinyalinin şifrelenmesi için bir cihaz sağlanmaktadır. Cihazı downmiks sinyalinin elde edilmesi için birden fazla kanalın downmikslenmesi üzere bir downmikser (1010) içermektedir. Dahası cihazı bir kalıntı sinyalin hesaplanması için adapte edilen bir kalıntı sinyali hesaplayıcı (1020) içermektedir. Ek olarak cihaz faz bilgisinin elde edilmesi için downmiks ve kalıntı sinyali arasındaki faz farkına ilişkin bilginin hesaplanması için adapte edilen bir faz bilgisi hesaplayıcı (1030) içermektedir. Dahası cihaz faz bilgisinin çıktılanması için bir çıktı üretici (1040) içermektedir.
