Kamar yadda zaku iya sani, ingancin sauti, latency na na'urorin Bluetooth daban-daban na iya bambanta sosai. Menene dalili? A yau za mu ba ku amsar wannan tambayar.
Babban ingancin watsa sauti na Bluetooth ya dogara ne akan bayanin martabar A2DP. A2DP kawai yana bayyana ƙa'ida da tsari don watsa bayanai masu inganci masu inganci kamar su mono ko sitiriyo akan tashar da ba ta da alaƙa da asynchronous. Wannan ƙa'idar tana kama da bututun watsa bayanan sauti. Bayanan da ake watsa ta Bluetooth an raba su zuwa nau'ikan masu zuwa bisa ga tsarin ɓoyewa:
menene SBC
Wannan shi ne daidaitaccen tsarin rikodin sauti na Bluetooth. A2DP (Babban Bayanan Rarraba Sauti) na dole tsari na coding na tilas. Matsakaicin adadin izini shine 320kbit / s a cikin mono da 512kbit / s a cikin tashoshi biyu. Duk guntuwar sauti na Bluetooth kuma za su goyi bayan wannan tsarin rikodin sauti.
menene AAC
Fasahar da Dolby Laboratories ke bayarwa, babban matsi ne mai rufa-rufa algorithm. iPhone yana amfani da tsarin AAC don watsa Bluetooth. A halin yanzu, na'urorin sauti na Bluetooth na Apple suna amfani da fasaha na ɓoye AAC. Kuma yawancin na'urori masu karɓa kamar masu magana da Bluetooth / belun kunne akan kasuwa suma suna tallafawa ƙaddamar da AAC.
menene APTX
Algorithm ɗin coding ne na CSR. Bayan da Qualcomm ya samo shi, ya zama babbar fasahar sa ta coding. An yi iƙirarin a cikin tallatawa cewa zai iya cimma ingancin sautin CD. Yawancin sabbin wayoyin Android suna sanye da APTX. Wannan fasahar coding mai jiwuwa ta fi inganci fiye da na gargajiya na Bluetooth, kuma jin sauraron ya fi na baya biyu. Na'urorin da ke amfani da fasahar APTX suna buƙatar neman izini daga Qualcomm kuma su biya farashin izini, kuma suna buƙatar samun goyan bayan ƙarshen watsawa da karɓa.
menene APTX-HD
aptX HD babban ma'anar sauti ne, kuma ingancin sauti kusan iri ɗaya ne da LDAC. Ya dogara ne akan classic aptX, wanda ke ƙara tashoshi don tallafawa tsarin sauti na 24 bit 48KHz. Amfanin wannan shine ƙananan sigina-zuwa-amo rabo da ƙarancin murdiya. A lokaci guda, yawan watsawa ba shakka yana ƙaruwa sosai.
menene Bayanin APTX-LL
aptX LL low-latency, babban fasalin shine yana iya cimma latency na kasa da 40ms. Mun san cewa iyakar latency da mutane za su ji shine 70ms, kuma kai 40ms yana nufin ba za mu iya jin jinkirin ba.
menene LDAC
Wannan fasaha ce ta rikodin sauti da SONY ta ƙera, wacce za ta iya watsa abun ciki mai inganci (Hi-Res). Wannan fasaha na iya watsa kusan sau uku fiye da sauran fasahohin coding ta hanyar ingantaccen coding da ingantaccen fakitin bayanan. A halin yanzu, wannan fasaha ana amfani da ita ne kawai a cikin na'urorin watsawa da karɓar na SONY. Don haka, saitin SONY na watsawa da karɓar kayan aiki waɗanda ke goyan bayan fasahar coding audio na LDAC kawai za'a iya siye don tallafawa watsa bayanan sauti na Bluetooth mai LDAC.
Feasycom ya gabatar da mafita guda biyu waɗanda ke goyan bayan tsarin APTX. Waɗanda za ku iya samun su a ƙasa:
Menene ra'ayinku game da wannan Gabatarwa Manyan Tsarin Sauti na Bluetooth guda 6? Jin kyauta don aika bincike don ƙarin cikakkun bayanai. Na gode da karanta wannan labarin.
