Kubwera kwaukadaulo wa digito m'dziko la nyimbo, funso linadzuka pakusankha njira zopangira digito, kukonza, ndi kusunga mawu. Mitundu yambiri yapangidwa, ndipo yambiri mwa iyo imagwiritsidwabe ntchito mwanjira zosiyanasiyana. Mothandizirana, amagawika m'magulu awiri: audio audio ndi otayika. Mwa akale, mawonekedwe a FLAC akutsogolera; mwa omalizirawa, eni akewo apita ku MP3. Nanga ndi zosiyana zikuluzikulu ziti pakati pa FLAC ndi MP3, ndipo ndizofunikira kwa omvera?
Kodi FLAC ndi MP3
Ngati mawu ajambulidwa mu mtundu wa FLAC kapena atasinthidwa kukhala mtundu wina wosatayika, mawonekedwe onse amawu ndi zambiri zowonjezera pazomwe zili mufayilo (metadata) zimasungidwa. Mawonekedwe a fayilo ali motere:
- zingwe zinayi zokuzindikiritsa (FlaC);
- Streaminfo metadata (kofunikira kukonza makina osewerera);
- Ma blockadata ena amtundu wina (mwa kufuna)
- mafelemu azomvera.
Ndi chizolowezi kujambula mwachindunji mafayilo a FLAC mukamasewera nyimbo kapena nyimbo za vinyl.

Kupanga ma algorithms opondereza mafayilo a MP3, mtundu wa psychoacoustic wamunthu unatengedwa ngati maziko. Mwachidule, pakutembenuka, magawo a mawonekedwe omwe makutu athu samazindikira kapena sakudziwa kwathunthu "adzadulidwa" kuchokera kumtsinje wolira. Kuphatikiza apo, ndi kufanana kwa mitsinje ya stereo pamagawo ena, amatha kusinthidwa kukhala nyimbo ya mono. Choyimira chachikulu pazomvera pamtunda ndicho kukanikiza - pang'ono pang'ono:
- mpaka 160 kbit / s - otsika kwambiri, zosokoneza zambiri zachitatu, maulendo apafupipafupi;
- 160-260 kbit / s - wapamwamba kwambiri, kubwereza kwapakati pa kutalika kwa nsonga;
- 260-320 kbit / s - apamwamba kwambiri, yunifolomu, phokoso lakuya lokhazikika.
Nthawi zina bitrate yapamwamba imatheka chifukwa chotembenuza fayilo yotsika kwambiri. Izi sizidzawongolera mawu mwanjira iliyonse - mafayilo osinthidwa kuchoka pa 128 kupita pa 320 bit / s adzamvekabe ngati fayilo ya-128.
Gome: Kuyerekeza kwa mawonekedwe ndi kusiyana kwamafomedwe
| Chizindikiro | Flac | Mulingo wotsika pang'ono | Kukwera kwambiri mp3 |
| Mtundu wopindika | osataya | ndi zotayika | ndi zotayika |
| Makhalidwe abwino | mkulu | otsika | mkulu |
| Kuchuluka kwa nyimbo imodzi | 25-200 Mb | 2-5 Mb | 4-15 Mb |
| Kusankhidwa | kumvera nyimbo pamakina apamwamba kwambiri, ndikupanga nyimbo zakale | kukhazikitsa Nyimbo Zamafoni, kusungira ndi kusewera mafayilo pazida zokhala ndi kukumbukira pang'ono | Kunyumba kumvetsera nyimbo, kusungidwa kwapa katemera pazida zosunthika |
| Kugwirizana | Ma PC, ma foni and manyoni, osewera kumapeto | zida zamagetsi zambiri | zida zamagetsi zambiri |
Kuti mumve kusiyana pakati pa fayilo yapamwamba kwambiri ya MP3 ndi fayilo ya FLAC, muyenera kukhala ndi khutu labwino kwambiri ndi nyimbo kapena pulogalamu yapamwamba kwambiri. MP3 ndizokwanira kumvetsera nyimbo kunyumba kapena popita, ndipo FLAC idakhalabe oimba, ma DJ ndi audi audiles.
