Аннотация:
Maqolada raqamli ovoz signallarini siqish texnologiyalarining nazariy va amaliy asoslari tahlil qilinadi. Tadqiqotda MP3, AAC va OGG formatlarining ishlash prinsiplari, ularning siqish samaradorligi, sifatga ta’siri hamda kodlash algoritmlarining farqlari yoritilgan. Maqolada psychoacoustic model, bitreyt boshqaruvi va yo‘qotishli (lossy) hamda yo‘qotishsiz (lossless) siqish usullarining qo‘llanish sohalari tahlil qilinadi. Raqamli audio texnologiyalarining multimedia tizimlarida, oqimli uzatish (streaming) va arxivlash jarayonlarida tutgan o‘rni, shuningdek, foydalanuvchi tajribasiga ko‘rsatgan ta’siri ilmiy asosda bayon etilgan. Maqola natijalari zamonaviy raqamli media tizimlarida samarali audio siqish texnologiyalarini tanlashda amaliy ahamiyatga ega.
