Lub FLAC hom ntawv yog txawv los ntawm lwm cov suab codecs?

Txij thaum nws cov inception cov suab kev lag luam tsis muaj ib tug tsis txaus tshwj xeeb tawm tswv uas yog siv los cawm thiab playback. Ntawm cov hoob kawm, qhov kev pheej cov neeg siv yog nto moo tshaj plaws rau cov laus MP3, tab sis hnub no nws twb raug thawb ib ncig ntawm lwm, ntau high-zoo thiab niaj hnub codecs.

Nws yog tam sim no ib tug ntawm cov feem ntau nrov ntawm cov suab paj nruag lovers yog lub FLAC hom. Nws pom qhov txawv feature yog cov compression algorithm nyob rau hauv uas qhov zoo tshaj tsis tsis yog tshwm sim.

Differing li los ntawm tus hlob thiab feem ntau lug siv codec, nws tsis tshem tawm los ntawm lub suab kwj tsis muaj "ntxiv" cov ntaub ntawv, thiab yog li ntawd yog tshwj xeeb yog zoo suited rau xav tau music lovers. Lub suab ntawm no zoo tsis yog tsuas yog zoo tagnrho rau cov playback rau lub twj paj nruag chav kawm ntawv Hi-End, tab sis kuj los tsim lawv tus kheej music collection.

Nyob rau hnub no, FLAC hom ntawv yog kev txhawb los ntawm tag nrho cov kev sau computer programs rau mloog suab paj nruag. Txawm li cas los, txhua txhua xyoo muaj ntau kho vajtse ntsiab uas pab kom tus neeg siv yuav txaus siab rau nws zoo kawg li lub suab.

Tus qauv ntawm no codec packs muaj xws li metadata Streaminfo, ntas thiab plaub bytes FLAC. Thawj yog cov bytes uas ua raws li cov cim ntawm tag nrho cov kwj thiab ces decoded metadata, tom qab uas twb yog ib tug compressed suab nws tus kheej. Sami metadata thiab audio kwj yog lossi alternated ntawm lawv tus kheej. Tsis tas li ntawd, lub tswv yim ntaub ntawv kwj yog muab faib mus rau hauv blocks, tom qab uas nws tshwm sim ywj siab ntawm lawv coding.

Tom qab coding, lawv yog compressed, yog lawv "styling" nyob rau hauv lub ntas. Yuav ua li cas yog txawm zoo, FLAC hom yuav siv cov blocks ntawm txawv ntau thiab tsawg, uas ua rau nws ua tau rau kom muaj lub zoo heev zoo ntawm lub suab.

Tsis ceeb, lub partitioning rau hauv blocks ntawm lub suab yog ib qho ntawm feem tseem ceeb heev theem ntawm encoding. Qhov luaj li cas ntawm txhua lub caij yog txiav txim raws li ib tug xov tooj ntawm cov yam ntxwv ntawm thawj zaug khoom. Yog hais tias koj txiav txim siab mus nce tus naj npawb ntawm xws blocks thaum encoding, nws yuav muaj ntau heev hais, alternating nrog ntas. Ntawm cov hoob kawm, nyob rau hauv cov ntaub ntawv no, lub compression efficiency yuav muaj ntau yam qis.

Txawm li cas los, siv ib yam nkaus thiab loj codec kuj tsis tau xaiv tus pom qauv ntaub ntawv compression. Nws yog ntseeg hais tias nyob rau hauv feem ntau koj yuav tau siv los ntawm 2 mus rau 6000 kuaj. Yuav kom tsim tau tus nqi ntawm kev txiav txim tsim nyog rau 44.1 kHz. Txij li thaum FLAC hom yuav tau mus qhia nws tag nrho tej zaum.

Nco ntsoov tias tom qab cov kev xaiv ntawm qhov ntsuas no yuav pib approximation ntawm lub teeb liab. Nov yog tib lub txiaj ntsim ntawm tus txheej txheem no yuav tau mus hlawv raws li me ntsis li sai tau lub xov tooj ntawm cov khoom. Cov tub txawg hu nws lub "noob uas seem tshuav." Nws yog qhov tsis muaj lub muaj nuj nqi yuav tsum tau kho, uas yog siv rau compression.

Los ntawm txoj kev, lub approximation yuav siv tau ob hom ntawm lawv. Thaum muaj ib tug xav los hloov FLAC ntaub ntawv rau MP3, siv tib lub kho cov ntaub ntawv, raws li txwv tsis pub nws yuav tsis tsim nyog tos rau cov qhov tso zis ua ntaub ntawv thov zoo.

Yog li, qhov no codec yog ib tug ntawm cov leading niaj hnub cov suab, txij li thaum tej zaum nws yuav kom lub siab tshaj plaws zoo compressed music. Ntawm cov hoob kawm, cov ntaub ntawv hom ntawv FLAC tsis muab ib tug compact luaj li cas ntawm cov zis tej ntaub ntawv, tab sis nws tsis yog tsim rau lub hom phiaj no.
