Abstract
Sunulan bulus yüksek frekans yeniden yapilandirma (HFR) (high frequency reconstruction) yöntemlerini kullanan dijital ses sinyali kodlama sistemleri ile ilgilidir. Daha istikrarli bir merkez kodek (core codec) performansi ve merkez kodek ile HFR sisteminde artirilmis bir ses (audio) kalitesi saglar. Ani ve en yüksek kalitede esik frekansi seçiminin yapilmasi için degisik metodlar sunulmaktadir.
