Abstract
Bir orta sinyal olarak bir birinci kombinasyon sinyalini (204) ve orta sinyalden türetilen öngörülmüş bir yan sinyal kullanılarak türetilebilen bir artık sinyali (205) elde etmek için iki ses kanalının (201, 202) birleştirilmesine dayalı olan bir ses kodlayıcı ve bir ses kodu çözücü açıklanmaktadır. Birinci kombinasyon sinyali ve öngörü artık sinyali kodlanır (209) ve bir optimizasyon hedefine (208) dayalı olarak bir iyileştirici (207) vasıtasıyla türetilen öngörü bilgisi (206) ile birlikte bir veri akışına (213) yazılır (212). Bir kod çözücü, kodu çözülmüş birinci kanal sinyalini ve kodu çözülmüş ikinci kanal sinyalini türetmek için öngörü artık sinyalini, birinci kombinasyon sinyalini ve öngörü bilgisini kullanır. Bir kodlayıcı örneğinde veyahut bir kod çözücü örneğinde, birinci kombinasyon sinyalinin spektrumunun sanal parçasını kestirmek için bir gerçekten-sanala dönüşüm uygulanabilir. Öngörü artık sinyalinin türetilmesinde kullanılan öngörü sinyalini hesaplamak için gerçek değerli birinci kombinasyon sinyali, karmaşık öngörü bilgisinin gerçek bir kısmıyla çarpılırken; birinci kombinasyon sinyalinin kestirilen sanal parçası, karmaşık öngörü bilgisinin sanal bir kısmıyla çarpılır.
