Mafaira eFACA anozivikanwa murasi isina kurasikirwa nzvimbo. Muhurukuro yedijitori, codec isina kurasika isingadi kurasikirwa chero ruzivo rwemashoko anokosha pamusoro peimhanzi yekare analogyo munguva yefaira-compression process. Makomodhe akawanda anozivikanwa anoshandisa kurasikirwa kwekunyora-kushandiswa-seenzaniso, MP3 neWindows Media Audio mitemo-iyo inorasikirwa nekutendeseka kwakanaka munguva yekushandura.
Ripping Music CDs
Zvechokwadi, vazhinji vashandisi vanoda kusimudzira maCD avo ekutanga anoteerera (CD ripping ) vakasarudza kushandisa FLAC kuchengetedza inzwi panzvimbo yekushandisa kurasikirwa kwemafaira . Kuita izvi kunovimbisa kuti kana chekutanga chakanga chakuvara kana kurasikirwa, ikopi ikopi yakakwana inogona kudzokororwa uchishandisa mahwendefa eFAC akaiswa kare.
Kunze kwevose vasina kurasikirwa mafirimu mafirimu akawanikwa, FLAC ndiyo inonyanya kuzivikanwa inoshandiswa nhasi. Zvechokwadi, mamwe mavhisi emimhanzi yeHDD zvino anopa maitiro mune iyi mafaira ekudhanira.
Kudonha CD audio ku FLAC inowanzobudisa mafaira ane kuwedzera kwepakati ye 30% uye 50 muzana. Nokuda kwemaitiro asina kurasikirwa, vamwe vanhu vanodawo kuchengeta mabhuku avo emumhanzi ye digalog seFLAC mafaira pane kunze kwekuchengetedza vhidhiyo uye kutendeukira kumararamiro anorasika ( MP3 , AAC , WMA , nezvimwewo) pazvinenge zvichidiwa-somuenzaniso, kuenzanirana kune MP3 mutambiri kana imwe mhando yefoni inoshandiswa.

FAC files inotsigira metadata tagging, album cover art, uye kutsvaga kutsvaga zvinyorwa. Nokuti iyo isiri yemaitiro neine mvumo yeumambo isina mvumo yekombiki yaro yepamusoro, FLAC inonyanya kufarirwa nevatangi vemuvhu rakazaruka. Kunyanya, kubudiswa kweFACAC nokukurumidza nekuenzanisa nekuenzaniswa nemamwe maitiro kunoita kuti zvive zvakakodzera pakuteerera kwepaIndaneti.
Kubva pane unyanzvi hwokuongorora, FLAC encoder inotsigira:
- Sampuli mitengo pakati pe1 Hz kusvika ku 65,545 Hz mu 1 Hz matanho, kana 10 Hz kusvika 655.350 Hz mu 10 Hz matanho, achishandisa pakati peyero nemasere
- PCM bit resolution ye 4 kusvika ku 24 bits nemuenzaniso (kunyange zvazvo yakagadziriswa-point, uye isati yakasviba-point, samples inotsigirwa)
FLAC Mirefu
Musoro wekutsvaga kweFACAC mafaira ndeyekuti hardware yakawanda haina natively kutsigira iyo. Kunyange zvazvo kombiyuta uye mafoni ekushandisa maitiro ari kutanga kutsigira FLAC, Apple haana kubatsigira kusvikira 2017 uye Microsoft kusvika 2016-pasinei nokuti codec yakatanga kusunungurwa muna 2001. Vatengi vemidziyo yevashandi havakwanisi kutsigira FLAC, pane kuvimba nekutasikirwa- asi-maitiro akafanana se MP3 kana WMA.
Chimwe chikonzero nei FLAC ingave yakanonoka kumhizha kubvumirwa, pasinei nekukwirira kwaro sekunyora kushandiswa kwemagetsi, ndeyokuti haibatsiri chero rudzi rwekodhi-kodzero yekugadzirisa kodzero. Mafaira eFACA, nemasikirwo, asingasviki ne-software licensing schemes, iyo yakagadzirisa kubatsira kwayo kwekutengeserana kwevatengesi vemabhizimisi uye makambani emakambani ekutengeserana.
