Pa bitrate bwino kuti ndi inaudible kwa pafupifupi aliyense. zimene sizosatheka ndi reversible, kotero kusintha kuti lossless mtundu amateteza dziko latsopano kuposa kubwezeretsa oyambirira. AAC ndi lossy koma bwino kuposa MP3, ndipo amagwira mpaka 48 ma channels mwachilengedwe kuposa kukhala bolted pa stereo kupanga.

Yes — format imagwira bwino ntchito ndi ma channels ambiri kuposa awiri, kotero kuti surround mix imasunga ma channels ake ophatikizidwa moyenera, osati kuikidwa mu stereo panjira.

Kulemba mawu kudzera pa ma bitrate ochokera kumawononga malo - amasunga mawu omwe kale apita kudzera pa lossy pass ndipo sabwezeretsa chilichonse chomwe chimatulutsidwa ndi wolemba mawu woyamba.
Kodi kugwiritsa ntchito AAC kumafunikira chilolezo cha patent?
