Incazelo ye-FLAC
I-Lossless Audio Audio Codec iyinqubo yokucindezela ekuqaleni eyakhiwe yi-nonprofit Xiph.org Foundation esekela amafayela alalelwayo adijithali afana ncamashi nemithombo yomthombo wokuqala. Amafayela e-FLAC-encoded, evame ukuthwala ukwandiswa kwe-.flac, ayaziwa ngokuba nomkhiqizo ovulekile ngokugcwele kanye namasayizi amancane wefayela kanye nezikhathi zokumemezela ngokushesha.
Amafayela we-FLAC athandwa esikhala sokulalelwayo esingalahleki. Ngomsindo we-digital, i- codec engalahleki yilapho engalahlekelwa yiluphi ulwazi olubalulekile lwesignali mayelana nomculo wokuqala we-analog ngesikhathi senqubo yokucindezela ifayela. Ama-codec amaningi athandwayo asebenzisa ama-algorithms alahlekile -okuyisibonelo, ama-MP3 nama-Windows Media Amazinga womsindo-alahlekelwa ukwethembeka okufanayo ngesikhathi sokuhumusha.
Ukukhipha ama-CD omculo
Eqinisweni, abasebenzisi abaningi abafisa ukuvuselela ama-CD abo okuqala alalelwayo (i-CD ripping ) bakhetha ukusebenzisa i-FLAC ukulondoloza umsindo kunokusebenzisa ifomethi elahlekile . Ukwenza lokhu kuqinisekisa ukuthi uma umthombo wokuqala uwonakele noma ulahlekile, ikhophi ephelele ingabuyekishwa ngokusebenzisa amafayela we-FLAC ngaphambilini.
Kuzo zonke amafomethi ezomsindo ezingalahleki atholakala, i-FLAC mhlawumbe ethandwa kakhulu namuhla. Eqinisweni, ezinye izinsiza zomculo ze-HD manje zinikeza amathrekhi kule fomethi yokulanda.
Ukuchofoza i-CD yomsindo ku-FLAC ngokuvamile iveza amafayela ngenani lokucindezela eliphakathi kwamaphesenti angu-30 namaphesenti angu-50. Ngenxa yendlela yokulahlekelwa kwefomethi, abanye abantu bakhetha nokugcina amareyibhuku womculo wedijithali njengamafayela we-FLAC emithonjeni yangaphandle yokugcina nokuguqula amafomethi alahlekile ( MP3 , AAC , WMA , njll) uma kudingeka-isibonelo, ukuvumelanisa kwi- MP3 umdlali noma olunye uhlobo lwedivaysi ephathekayo.
Izimfanelo ze-FLAC
I-standard ye-FLAC isekelwe kuzo zonke izinhlelo zokusebenza ezinkulu, kufaka phakathi i-Windows 10, i-MacOS High Sierra nangaphezulu, ukusabalalisa okuningi kwe-Linux, i-Android 3.1 nokusha, ne-iOS 11 nokusha.
Amafayela we-FLAC asekela ukumaketha kwe-metadata, ubuciko bekhava le-albhamu, nokufuna ngokushesha okuqukethwe. Ngenxa yokuthi ifomethi engafanelekayo ngelayisense yamahhala ayikho emthethweni, i-FLAC ithandwa kakhulu ngabathuthukisi bokuvula umthombo. Ngokuyinhloko, ukusakaza okusheshayo kwe-FLAC nokuqhathaniswa ngokuqhathaniswa namanye amafomethi kwenza kube kufanelekile ukudlala oku-intanethi.
Kusukela kumbono wezobuchwepheshe, i-encoder ye-FLAC isekela:
- Izinga lokulinganisa phakathi kuka-1 Hz kuya ku-65,545 Hz ngezinyathelo ezingu-1 Hz, noma ama-Hz angu-10 kuya ku-655,350 Hz ngezinyathelo ezingu-10 ze-Hz, usebenzisa phakathi kweziteshi eziyisishiyagalombili nesishiyagalombili
- Isixazululo samaminithi we-PCM samabhithi angu-4 kuya kwangu-24 ngesampula (nakuba yi-point-fixed kuphela, futhi hhayi-floating-point, amasampuli asekelwa)
Ukulinganiselwa kwe-FLAC
Ukunciphisa okuyinhloko kumafayela we-FLAC yilokho i-hardware eningi ayisekeli natively. Nakuba izinhlelo zekhompiyutha neye-smartphone seziqale ukusekela i-FLAC, i-Apple ayizange isekele kuze kufike ngo-2017 no-Microsoft kuze kube ngu-2016-naphezu kokuthi i-codec yaqala ukukhishwa ngo-2001. Abadlali be-hardware abathengi ngokuvamile abaxhasi i-FLAC, kunalokho bathembele ekulahlekeni- kodwa-amafomethi avamile afana ne-MP3 noma i-WMA.
Esinye isizathu sokuthi i-FLAC ingase ibe ne-slower adoption industry, naphezu kokuphakama kwayo njenge-compression algorithm, ukuthi ayisekeli noma yiluphi uhlobo lokuphathwa kwamalungelo adijithali. Amafayela we-FLAC, ngokuklanywa, angenawo ama-software amalayisenisi okulayisense, okwehlise ukuwusizo kwabathengisi bokusakaza kwezomnotho kanye nembonini yomculo wezohwebo ngokugcwele.
