Nke a bụ usoro ngbanwe ọkọlọtọ maka ọdịyo Bluetooth. A2DP (Advanced Audio Distribution Profile) usoro koodu amanyere iwu. Oke kacha mma bụ 320kbit / s na mono na 512kbit / s na ọwa abụọ. Ihe ibe ọdịyo Bluetooth niile ga-akwadokwa usoro ngbanwe ọdịyo a.
ihe bu AAC
Teknụzụ nke Dolby Laboratories na-enye, ọ bụ oke mkpakọ itinye koodu algọridim. iPhone na-eji usoro AAC maka nnyefe Bluetooth. Ka ọ dị ugbu a, ngwaọrụ ọdịyo Bluetooth nke Apple na-eji teknụzụ ntinye koodu AAC. Na ọtụtụ ndị na-anata ngwaọrụ dị ka Bluetooth ọkà okwu / ekweisi na ahịa na-akwado AAC decoding.
