Fumana iinyani malunga neeCD neeCD kunye neefom zeediski ezihambelanayo
Nangona ii-CD zangaphambili ezirekhodwayo ziye zalahlekelwa yinkanuko yazo ngokulula kokusasazwa kwemculo yedijithali kunye nokulandwa , yi-CD eyayiqalile ukuhlaziywa komculo wedijithali. Abaninzi bayathanda ama-CD kwaye bobabili bathenga baze badlale rhoqo. Nantsi oku kufuneka ukwazi ngeCD CDs, kunye neefom e-disc-based based.
I-CD Audio Format
I-CD imele iCompact Disc. I-Compact Disc ibhekisela kwidiski kunye nefomathi yokudlala ye-digital yenziwe yi Philips kunye no-Sony apho i-audio ikokhowudi yekhowudi, efana neendlela zekhomputha zekhompyutheni (i-1 kunye ne-0), zibe yimikhosi kwi-disc, usebenzisa inkqubo ebizwa ngokuba yi- PCM oluphikisayo lwemathematika yomculo.
I-CD yokuqala yokurekhodwa yenziwe eJamani ngo-Agasti 17, 1982. Isihloko sokuqala sokurekhoda kwe-CD epheleleyo: uRichard Strauss '- Alpine Symphony . Kwaye kamva ngaloo nyaka, ngo-Oktobha 1 ka-1982, ukuba abadlali beCD bafumaneka kwi-US naseJapan. I-CD yokuqala eyathengiswayo (yokuqala eJapan) yayiyiSitrato sika- 52 sikaBilly Joel esasikhululwe ngaphambili kwi-vinyl ngo-1978.
I-CD iqalile ukuguqulwa kwedijithali kwi-audio, PC Gaming, izicelo ze-PC zokugcina, kunye negalelo ekuphuhlisweni kweDVD. U-Sony kunye ne-Philips babambene namalungelo obhaliso ekuphuhliseni ubugcisa beCD kunye ne-CD player.
Ifomathi ye-CD evakalayo ikwabizwa ngokuba yi-"Redbook CD".
Ukufumana ulwazi olungakumbi kwimbali yeCD audio, khangela ingxelo evela kwi-CNN.com.
Kwakhona, khangela isithunzi kunye nokuhlaziywa okupheleleyo (ebhalwe ngo-1983 ngu-Stereophile Magazine) yomdlali wokuqala weCD othengiswe ebantwini.
Ukongeza kwi-audio pre-erekhodiweyo, ii-CD zingasetyenziselwa kwezinye izicelo ezininzi:
- I-CD-R- CD-R imele i-CD-Recordable. Ezi diski zingasetyenziselwa ukurekhoda okanye "ukutshisa" umculo okanye idatha usebenzisa i-CD Recorder (umculo kuphela) okanye i-PC (umculo okanye idatha). Amanye ama-CD-R akhethwe ukurekhoda komculo kuphela kwaye abanye banokurekhoda zombini umculo okanye idatha. Ii-CD-R zingabhalwa kuphela.
- I-CD-RW - Iinjongo ezifanayo njenge-CD-R, ngaphandle kokuba iCD ingasuswa kwaye isetyenziswe kwakhona (i-RW ityunithi ibonisa kwakhona kwakhona).
- I-MP3-CD - I -CD ye- CD ingaba i-CD-R okanye i-diski ze-RW ezifakwe kwiifayile zomculo ze-MP3, endaweni yeefayile ze-CD zomsindo. Ezi diski zingadlala kwi-CD, iDVD kunye ne-Blu-ray Disc abadlali (kufuneka uhlolisise iimpawu zomdlali).
- I-JPEG CD ye-Photo - I-JPEG yeCD Photo ingaba yirekhodi ye-CD-R okanye ye-RW enezithombe kuyo kubhalwe kwifom yefayile yeJPEG. I-JPEG IiCD zeefoto zingadlala kwii-PC kunye neCD, i-DVD kunye nabadlali be-Blu-ray Disc.
- I-VideoCD - Ukongeza kwizandi kunye neefoto, ungaphinda ubhale ividiyo kwiCD . Oku akufani neDVD, kwaye umgangatho ube phakathi kwe-DVD neVHS ifomathi. Kwakhona ii-CD zevidiyo azikwazi ukudlala kwiidlali zeCD, ngaphandle kokuba umdlali weCD enexhumo lokuxhuma kwividiyo (okungenakwenzeka) - nangona abadlali be-VideoCD abaye bazinikela kwiimakethe ezininzi zase-Asia. IiVCDCD zidlalwa kwiDVD edibeneyo kunye nabadlali be-Blu-ray disc.
HDCD
I-HDCD yintshintsho yomgangatho we-CD womsindo owandisa ulwazi oluvakalayo olugcinwe kwisignali se-CD ngama-4-bits ( iiCD zisekelwe kwi-tebnoloji ye-audio ) kuma-20bits, i-HDCD inokwandisa amandla oononongo we-teknoloji ye-CD yangoku kwimilinganiselo emitsha, kodwa iyakunceda, iiCDs ezifakwe kwiCDCD zidlalwe kwiidlali ze-CDCD ezingekho phantsi kwe-HD Kwakhona, njengemveliso-yecandelo lokucoca ngokucacileyo kwii-HDCD chips, ii-CD eziqhelekileyo ziya kuzwakala zigcwele kwaye zendalo ngokwemidlalo yeCDCD.
I-HDCD yayisungulwe ekuqaleni yiPacific Microsonics, kwaye kamva yaba yipropati ye-Microsoft. I-disk yokuqala ye-HDCD yakhululwa ngo-1995, kwaye nangona ingazange ifumane i-CD ye-Redbook ifomathi, izihloko ezingaphezu kwama-5,000 zakhishwa (khangela uluhlu oluthile).
Xa uthengisa ii-CD zomculo, khangela ii-initials ze-HDCD kumva okanye emaphaketheni yangaphakathi. Nangona kunjalo, kukho ukukhutshwa okuninzi okungabandakanyi ilebula ye-HDCD, kodwa, kusenokuba kusekho iiDVDCD. Ukuba unomdlali weCD obonisa ukucacisa i-HDCD, uya kuyifumana ngokuzenzekelayo kwaye anikezele ngeenzuzo ezingeziwe.
I-HDCD iphinde ibhekiswe njengeNgcaciso ePhakamileyo yeDiskrikhi yeDiskrikhi, iNgcaciso yeNgcaciso yeDiskrikhi yeDiskrikhi yeDiskrikhi, iNgcaciso yeNgcaciso yeDisk
SACD
I-SACD (i-Super Audio Compact Disc) ifom ye-disk audio-resolved eyenziwe ngu-Sony no-Philips (oye wavelisa iCD). Ukusebenzisa ifom yeFayile yeDirect Direct (iDDD) ifomathi, i-SACD inikezela ngokuvelisa ngokuchanekileyo ngokuchanekileyo kunokuba i- Pulse Code Modulation (PCM) isetyenziswe kwifomathi ekhoyo yangoku.
Nangona i-CD ifomathi ifanelwe kwizinga lokulinganisa i-44.1 kHz , i-SACD isampula kwi-2.8224 MHz. Kwakhona, kunye nomthamo wokugcina we-4.7 gigabytes kwi disk (ngokuninzi neDVD), i-SACD ikwazi ukuhlala ngokuxubana okuhlukeneyo kweeterefeshi kunye nesithandathu. Ifomathi yeSACD nayo inokukwazi ukubonisa ifoto kunye neenkcukacha zetekisi, njengamanqaku e-liner, kodwa le nto ayifaki kwii-discs ezininzi.
Abadlali be-CD abakwazi ukudlala i-SACD, kodwa abadlali be-SACD bahambelana ngokutsha kunye neeCD eziqhelekileyo, kwaye ezinye iidiski ze-SACD zixubusha ezimbini kunye ne-PCM. Ngamanye amagama, enye idiski inokubamba zombini i-CD version kunye ne-SACD inguqu yezinto ezirekhodiweyo. Oko kuthetha ukuba unako ukutyalombela kwi-SACD ye-two-format ukudlala kwi-CD yakho yangoku kwaye ufikelele kwi-SACD into efanayo kwi-disc efanayo kamva kwi-SACD-ehambisanayo nomdlali.
Kumele kuqatshelwe ukuba akuyiyo yonke i-disk ye-SACD ene-CD engumgangatho ophantsi-oko kuthetha ukuba kufuneka uhlolisise iilebula ye-disc ukuze ubone ukuba i-disk ethile ye-SACD nayo ingadlala kumdlali oqhelekileyo weCD.
Ukongeza, kukho i-DVD ephezulu, i- Blu-ray kunye ne-Ultra HD Disc abadlali banokudlala i-SACD.
I-SACD ingafika kwiinguqu ezi-2 okanye iinguqu ezininzi. Kwiimeko kunye ne-SACD ine-CD yoshicilelo kwi-disc, i-CD iya kuhlala i-2-channel, kodwa isalathisi se-SACD ingaba ngu-2 okanye ingqungquthela yamashishini amaninzi.
Enye into eyongeziweyo ukubonisa ukuba ididithi yefayile yeDSD ifomathi yokusetyenziswa kwe-SACD ibuye isetyenziswe njengenye yeefom ezifumanekayo ezisetyenziselwa ukulandwa kwee-Hi-Res . Oku kunika abaphulaphuli bemvumi ukuphucula ikhwalithi kwifom engekho yomzimba yee diski.
I-SACD ikwabizwa ngokuba yi-Super Audio CD, i-Super Audio Compact Disc, i-SA-CD
