Ngalolu suku, FLAC format isekelwa zonke izinhlelo zekhompyutha ukulalela umculo. Nokho, njalo ngonyaka bangaphezu hardware izixazululo ukuthi unike amandla umsebenzisi athokozele umsindo zakhe ezimangalisayo.

Isakhiwo saleli amaphakethe ngekhodekhi zihlanganisa imethadatha Streaminfo, ozimele kanye amabhayithi ezine FLAC. Okokuqala kunama-amabhayithi ukuthi uba isihlonzi yazo zonke ukusakaza bese ukukhishwa imethadatha, ngemva kwalokho kakade kuyinto ecindezeleke umsindo uqobo. Sami imethadatha yomsindo wokusakaza njalo alternated phakathi kwabo. Ngaphezu kwalokho, ukusakaza kwedatha yokufaka sehlukaniswe amabhlogo, ngemva kwalokho-ke kwenzeka esizimele esephepheni yabo.

Akumangalisi ukuthi partitioning ku amabhlogo umsindo ingenye izigaba ezibucayi kakhulu wekhodi. Usayizi element ngayinye kunqunywa esekelwe eziningi izici impahla kokuqala. Uma unquma ukwandisa isibalo amabhlogo enjalo lapho ikhodi, kuyoba zinezinto eziningi, nese ozimele. Yiqiniso, kulesi simo, nekusebenta kokucindezelwa kuyoba aphansi kakhulu.

Nokho, usebenzisa ngekhodekhi inkulu kakhulu futhi ngeke bakwazi ukukhetha elilungile imodeli idatha. Kukholakala ukuthi ezimweni eziningi udinga ukusebenzisa kusuka amasampula 2 kuya 6000. Ukuze usungule ukubaluleka ngokubona ezidingekayo 44,1 kHz. Njengoba FLAC format uzokwazi ukuba embule amandla ayo egcwele.

Qaphela ukuthi ngemva ukukhethwa le nkomba uzoqala isilinganiselo isiginali. Yilokho nje umphumela ofanayo yale nqubo kudingeka ashise ngangokusemandleni inani izingcezu. Professionals basibiza ngokuthi "insali." Kuyinto kwemigomo umsebenzi okumele encoded eyayisetshenziselwa kokucindezelwa.

By endleleni, le isilinganiselo ingasetshenziswa izinhlobo ezimbili kubo. Lapho kunesidingo ukuguqula amafayela FLAC MP3, besebenzisa imininingwane efanayo anekhodi, njengoba kungenjalo akudingekile ukulinda izinga ifayela okukhiphayo.
