The FLAC nemanyorerwo rakasiyana nemamwe digitaalinen Audio codecs?

Kubvira pakutanga kwayo ari digitaalinen okuteerera indasitiri haana ruzivo kuperevedza anokosha zvinogona kuti zvinoshandiswa kuponesa playback. Chokwadi, avhareji User chinonyanya inozivikanwa yekare MP3, asi nhasi akanga kusundwa kumativi vamwe, zvikuru yepamusoro uye codecs ano.

Yava imwe yenzvimbo dzine mukurumbira pakati vanoda mumhanzi ndiye FLAC format. Its runoratidza chaiwo compression algorithm umo unhu kurasikirwa asiri kunoitika.

Akasiyana pakudaro kuvakuru uye rinonyanya kushandiswa codec, hazvina kubvisa ekuteerera achamhanyira hapana Data "mamwe", uye naizvozvo kunonyanya unonyatsokodzera yakawanda vanoda mimhanzi. Kurira unhu uhwu rakanakira playback pamusoro chiridzwa kirasi Hi-End kwete chete, asiwo kuti pave zvavo pachavo mumhanzi muunganidzwa.

On nhasi, FLAC youduku chinotsigirwa zvose ekombiyuta kuti mimhanzi. Zvisinei, rimwe gore pane zvakawanda Hardware zvinogadzirisa kuti dzinoita inodzidzisa kunakidzwa inzwi rake kwazvo.

Sechivako ichi codec packs it zvinosanganisira metadata Streaminfo, mapuranga uye bytes mana FLAC. First ndiwo bytes kuti mabasa sezvo identifier pamusoro yorwizi zvose uye ipapo decoded metadata, pashure iyo kare ndiro compressed inzwi pacharo. Sami metadata uye Audio rukova kunoramba alternated pakati pachavo. Uyezve, mazano Data rukova rakakamurwa zvinogumbura, pashure pacho kunoitika pasina Coding yavo.

Mushure Coding, ivo compressed, pane "Kugadzira" dzavo mapuranga. Chii kunyange nani, FLAC youduku kunosanganisira kushandisa namatombo inosiyana, izvo zvinoita kuti tikwanise kuramba ari yokuisvonaka nokurira.

Hazvishamisi partitioning kupinda inoperera ruzha ndechimwe chezvinhu dzinonetsa zvokukura yeEncoding. Ukuru nechimwe chine maatomu akafanana akatsunga kunobva dzinoverengeka zvechadenga kutanga zvinhu. Kana ukasarudza kuwedzera nhamba dzakadaro kutigumbura kana yeEncoding, zvichava akawandisa okunze, rakatumbuka pamwe mapuranga. Zvechokwadi, mune ichi zvazvingava, compression kushanda achava yakaderera zvikuru.

Zvisinei, kushandisa codec wakakurisa uyewo haana kukwanisa kusarudza Zvakanyanya Kunaka Panguva Yepamuviri womuenzaniso date compression. Zvinofungidzirwa kuti kakawanda unofanira kushandisa kubva 2 kusvika 6000 ivhu. Kuti asimbise kukosha uchenjeri hunodiwa kuti 44,1 kHz. Sezvo FLAC nemanyorerwo achakwanisa kuzivisa zvizere kwadzo.

Ona kuti pashure kusarudzwa chinoratidza ichi achatanga rakada chiratidzo. Ndizvo chete mugumisiro izvi vanofanira kupisa sezvo shoma sezvinobvira kuwanda nematomhu. Nyanzvi vanouti "vakasara." Ndiyo parameters ari kushanda kuti encoded, yaishandiswa nokuda compression.

By munzira, rakada inogona kushandiswa mhando vaviri. Kana pane vanoda kutendeutsa FLAC mafaira kuti MP3, uchishandisa chete encoded data, sezvo zvimwe hazvisi zvakakodzera kuti kumirira goho faira yepamusoro.

Saka, codec ichi ndechimwe kutungamirira ano digitaalinen inzwi, sezvo zvingadaro nechokwadi chemhando yepamusoro compressed mumhanzi. Chokwadi, faira pamanyorerwo FLAC haripi chitsidzo kukura goho faira, asi haina kusikirwa kuti chinangwa ichi.
