He aha te LDAC?
Ko te LDAC he hangarau whakawaehere reo ahokore i whakawhanakehia e Sony. I hura tuatahi i te 2015 CES Consumer Electronics Show. I taua wa, i kii a Sony ko te hangarau LDAC e toru nga wa pai ake i te paerewa Nihokikorangi whakawaehere me te punaha taapiri. Ma tenei ara, e kore e nui rawa atu te kopiri o aua konae ororongo taumira teitei ina tuku ahokore, ka tino whakapai ake te kounga oro.
I te wa e tuku ana i te ororongo taumira teitei LPCM, ka mau tonu te hangarau LDAC i tona hohonutanga moka moka me te awhe whakautu auau, ka taea te tuku kounga teitei ahakoa te ororongo 96kHz/24bit. Engari, ko te hangarau tuku ororongo Nihokikorangi tuku iho, i mua i te tuku ororongo LPCM, i te wa e whakawhiti ana i nga raraunga ororongo, ko te mea tuatahi ko te "whakaheke" i te ataata taumira teitei ki te kounga CD o 44.1 kHz/16 bit, ka tuku ai. ma te 328 kbps, ka nui te ngaro o nga korero, mo te RUA. Ko te mutunga tenei: he kino rawa atu te kounga oro whakamutunga i te kounga taketake o te CD.
ENGARI, ko te tikanga ka taea anake te whakamahi i tenei hangarau ki nga taputapu a Sony.
He aha te aptX?
Ko te AptX he paerewa kotēkē ororongo. Kua whakaurua te paerewa ki te kawa tuku ororongo tiwha a Bluetooth A2DP. Ko te paerewa whakawaehere ororongo tiwharewha Nihokikorangi tuku iho ko: SBC, e mohiotia ana ko narrowband coding, a ko aptX he paerewa whakawaehere hou i whakauruhia e TKT. I raro i te ahuatanga o te whakawaehere SBC, ko te wa roa o te tuku oro oro oro Nihokikorangi i runga ake i te 120ms, ka taea e te paerewa whakawaehere aptX te awhina ki te whakaheke i te roa ki te 40ms. Ko te whakaroa ka rongohia e te nuinga o te tangata ina kei runga ake i te 70ms te roanga. No reira, ki te tangohia te paerewa aptX, kare te kaiwhakamahi e rongo i te roa o te whakamahi tuturu, pera i te wheako o te maataki tika i te pouaka whakaata me nga taringa kau.
Ko Feasycom, ko tetahi o nga kaiwhakarato otinga Nihokikorangi pai, i whakawhanakehia e toru nga waahanga Nihokikorangi rongonui me te hangarau aptX, aptX-HD. Na ko ratou:
