Ifomati FLAC yahlukile kwezinye womsindo yedijithali?

Ukususela ekusekweni kwayo ishishini digital komsindo ukhe awafumana ukunqongophala yeefomati ezizodwa zisetyenziselwa ukugcina kanye ukudlalwa. Kakade ke, lo umsebenzisi umlinganiselo edume kakhulu ukuba MP3 ubudala, kodwa namhla ke Undityhale macala enye, ngakumbi ezikumgangatho ophezulu kunye codecs mihla.

Ngoku omnye ethandwa kakhulu phakathi abathandi umculo ifomati FLAC. msebenzi wayo lokwahlula le algorithm ucinezelo ethile apho ilahleko umgangatho ngenkankulu kwenzeka.

Ezahlukeneyo ngoko ukusuka codec endala lusetyenziswa kakhulu, ayithethi ukususa ukusuka odiyo ngumsinga akukho data "extra", yaye ngoko ngokukodwa awunankinga befuna abathandi umculo. Yiveni olu phawu kuphela iyilungele ukudlala eklasini isixhobo Hi-End, kodwa ukwenza ingqokelela zabo umculo.

Ngale mini, ifomathi FLAC ixhaswe zonke iinkqubo zekhompyutha sokumamela umculo. Noko ke, nyaka ngamnye kukho izisombululo sezixhobo zekhompyutha ezenza umsebenzisi ukunandipha isandi zakhe ezimangalisayo.

Ubume le miqulu codec ziquka semethadata Streaminfo, nezesakhelo kwaye bytes ezine FLAC. Okokuqala ke bytes ikwasebenza njengoko Umchongi wendawo yonke mlambo aze ke decoded metadata, emva koko sele kuvakala abe ngokwayo. Sami iimpawu kunye komsindo uhlala mzuzu phakathi kwabo. Ngaphaya koko, i-data stream igalelo zahlulwe phakathi zaziibloko, emva koko kwenzeka ezimeleyo iikhowudi yabo.

Emva esephepheni, ukuba abe, kukho "nesimbo 'yabo lezakhelo. Yintoni bhetele, ifomathi FLAC iquka ukusetyenziswa iibhloko ezinobukhulu obahlukileyo, nto leyo eyenza kube lula ukugcina umgangatho ogqwesileyo yesandi.

Akumangalisi ke, izahlulelo ibe iibloko isandi yenye manqanaba ezininzi ezibalulekileyo encoding. Ubungakanani isiqalelo ngasinye kumiselwa ngokusekelwe kwinani iimpawu ezibonakalayo sokuqala. Ukuba ugqiba ukwandisa inani iibhloko ezinjalo xa usebenzisa ikhowudi, kuya kuba izinto ezininzi kakhulu, ngelinye kunye lezakhelo. Kakade ke, kulo mzekelo, ukwanela ucinezelo liya kuba ngaphantsi kakhulu.

Noko ke, esebenzisa codec enkulu kakhulu nayo kuba nako ukukhetha ngokupheleleyo ucinezelo imodeli data. Kukholelwa ukuba ufuna kwiimeko ezininzi ukusebenzisa ukusuka iisampulu-2 ukuya 6000. Ukumisela ixabiso ngokwengqiqo eyimfuneko 44,1 kHz. Ekubeni format FLAC uya kuba nako nje wena ukuyityhila kwisakhono sawo esipheleleyo.

Qaphela ukuba emva nokukhethwa kwesi salathisi iza kuqalisa isilinganiselo uphawu. Yiloo nto kuphela isiphumo efanayo yale nkqubo kufuneka ukuba zibaswe kancinci kangangoko inani ziikhowudi. Iingcali bayibiza ngokuba "intsalela." Yeyona Ipharamitha umsebenzi enkhowudwa, eyayisetyenziselwa ucinezelo.

Ngendlela, ukuba kelelo ingasetyenziswa iintlobo ezimbini kubo. Xa kukho imfuneko ukuguqula iifayile FLAC kwi MP3, kusetyenziswa iinkcukacha ezifanayo nee-encoded, njengokuba kungenjalo akuyomfuneko ukuba silindele ukuba umgangatho ifayile yemveliso.

Ngenxa yoko, le codec yenye phambili isandi digital mihla, kuba oko ukuqinisekisa umgangatho umculo ephezulu zixinaniswe. Kakade ke, lo ifomati yefayile FLAC akuthethi ukunika ubungakanani indawo lwefayile yogalelo, kodwa asinguye umntu owabakho ngenxa yale njongo.
