Abstract
Bir armonik ses sinyalinin Modifiye Edilmiş Ayrık Kosinüs Dönüşümü (MDCT) katsayılarının (Y(k)) kodlanması için bir aygıt olup, şu elemanları içerir: Önceden belirlenmiş bir eşik değeri aşan büyüklüklere sahip spektral piklerin yerlerinin tespit edilmesi için araçlar. Yerleri tespit edilmiş pikleri içeren ve çevreleyen pik bölgelerinin kodlanması için araçlar. Pik bölgelerinin dışında bulunan ve bir geçiş frekansının altında olan katsayıların bir birinci düşük frekans kümesinin, birkaç ayrılmış bit kullanılarak kodlanması için araçlar. Pik bölgelerinin dışında bulunan henüz kodlanmamış katsayıların en az bir yüksek frekans kümesinin bir gürültü tabanı kazancının, birkaç ayrılmış bit kullanılarak kodlanması için araçlar.
