Chii chinonzi LDAC?
LDAC iwaya isina waya yekukodha tekinoroji yakagadziriswa neSony. Yakatanga kuvhurwa pa2015 CES Consumer Electronics Show. Panguva iyoyo, Sony yakataura kuti tekinoroji yeLDAC yaive yakapetwa katatu kupfuura yakajairwa Bluetooth encoding uye compression system. Nenzira iyi, iwo epamusoro-resolution maodhiyo mafaira haazonyanyi kudzvanywa kana isina waya, izvo zvinonyanya kusimudzira mhando yekurira.
Kana uchitumira LPCM yakakwirira-resolution odhiyo, tekinoroji yeLDAC inochengetedza kudzika kwayo kwepamusoro uye frequency yekupindura renji, ichigonesa kutapurirana kwemhando yepamusoro kunyangwe pa96kHz/24bit odhiyo. Kusiyana neizvi, tekinoroji yechinyakare yeBluetooth audio transmission tekinoroji, isati yatumira LPCM odhiyo, kana uchiendesa odhiyo data, chinhu chekutanga kuita "kudzikisira" vhidhiyo yakagadziridzwa kusvika paCD mhando ye44.1 kHz/16 bit, wobva waitumira. kuburikidza ne328 kbps, izvo zvinokonzeresa kuwanda kwekurasikirwa kweruzivo, kwe TWICE. Izvo zvaizotungamira kumagumo aya: iyo yekupedzisira ruzha rwemhando yakaipisisa kupfuura yekutanga mhando yeCD.
ASI, kazhinji tekinoroji iyi inogona kushandiswa chete kumidziyo yeSony.
Chii chinonzi aptX?
AptX ndeyeodhiyo codec chiyero. Iyo chiyero inosanganiswa neBluetooth A2DP stereo audio transmission protocol. Iyo yechinyakare Bluetooth stereo odhiyo yekukodha chiyero ndeye: SBC, inowanzozivikanwa senarrowband coding, uye aptX chiyero chitsva chekodhi chakaunzwa neCSR. Pasi pemamiriro eSBC encoding, iyo Bluetooth stereo audio transmission yekunonoka nguva yaive pamusoro pe120ms, nepo aptX encoding standard inogona kubatsira kudzikisa latency kusvika 40ms. Kunonoka uko vanhu vazhinji vanogona kunzwa kana latency iri pamusoro pe70ms. Naizvozvo, kana iyo aptX chiyero ikagamuchirwa, mushandisi haanzwe kunonoka mukushandiswa chaiko, sechiitiko chekuona TV zvakananga nenzeve dzisina.
Feasycom, seimwe yeakanakisa Bluetooth mhinduro vanopa, yakagadzira matatu anozivikanwa maBluetooth module ane aptX, aptX-HD tekinoroji. Uye ivo:
Nguva inotevera paunenge uchitsvaga mhinduro kune yako isina waya audio projekiti, usakanganwe KUMBIRA RUBATSIRO FEASYCOM!
