Pokhala ndi zamakono zamakono mu nyimbo zamtundu, panali funso lokhudza njira zogwiritsira ntchito digitizing, processing ndi kusunga phokoso. Mafomu ambiri apangidwa, ambiri omwe amagwiritsidwa ntchito mogwiritsidwa ntchito mosiyanasiyana. Mwachidziwitso, iwo agawidwa m'magulu akulu awiri: audio yopanda pake (yoperewera) ndi imfa (yotayika). Zina mwa zomwe kale, FLAC zikutsogolera, pakati pa anthu omalizawa, enieni okhawo anapita ku MP3. Kotero ndi kusiyana kotani pakati pa FLAC ndi MP3, ndipo kodi ndi zofunika kwa omvera?
Kodi FLAC ndi MP3 ndi chiyani?
Ngati mauthenga amalembedwa ku FLAC kapena kutembenuzidwa kuchokera ku mtundu wina wosayeruzika, maulendo osiyanasiyana ndi zina zambiri zokhudza zomwe zili mu fayilo (metadata) zimasungidwa. Fayiloyi ndiyiyi:
- chingwe chodziwika chinayi (FlaC);
- Masewu a Streaminfo (oyenera kukhazikitsa zipangizo zochezera);
- zovuta zina zamtundu (zosankha);
- audiofremy.
Mchitidwe wa kujambula mwachindunji mafayilo a FLAC panthawi yomwe nyimbo zimakhala "moyo" kapena zolemba za vinyl zili ponseponse.

Pakukulitsa machitidwe ophatikizira a ma MP3 mafayilo, chitsanzo cha maganizo cha munthu chinatengedwa ngati maziko. Mwachidule, panthawi ya kutembenuka, mbali zonse za makutu omwe makutu athu sadziwa kapena sakudziwa bwinobwino "adzadulidwa" kuchokera kumtsinje wamtundu. Kuwonjezera apo, ngati mitsinje ya stereo ndi yofanana pa magawo ena, akhoza kutembenuzidwa kukhala mono sound. Chinthu chachikulu cha khalidwe lakumvetsera ndi kupanikizira chiŵerengero - bitrate:
- mpaka kbps 160 - khalidwe lochepa, kusokonezeka kwamtundu wina, kusungunuka mufupipafupi;
- 160-260 kbps - khalidwe labwino, kubwezeretsa pakati pa maulendo apamwamba;
- 260-320 kbps - khalidwe lapamwamba, yunifolomu, phokoso lakuya ndi zosokoneza.
Nthawi zina zimakhala zochepa kwambiri zomwe zimachitika potembenuza pang'onopang'ono. Izi sizikukweza khalidwe lakumveka - mafayilo osinthidwa kuchokera 128 mpaka 320 bps adzalinso ngati fayilo 128-bit.
Mndandanda: kuyerekezera makhalidwe ndi kusiyana kwa mawonekedwe a audio
| Chizindikiro | FLAC | Low bitrate mp3 | High bitrate mp3 |
| Zosinthika | yopanda kanthu | ndi kutayika | ndi kutayika |
| Mtundu wamamveka | pamwamba | otsika | pamwamba |
| Vuto la nyimbo imodzi | 25-200 MB | 2-5 MB | 4-15 MB |
| Cholinga | kumvetsera nyimbo pa machitidwe apamwamba a audio, kupanga nyimbo zosungira nyimbo | sungani mawonesi, sungani ndi kusewera mawindo pa zipangizo zopanda malire | kunyumba kumvetsera nyimbo, kusungiramo kabukhu pa zipangizo zamakono |
| Kugwirizana | PC, mafoni ena ndi mapiritsi, osewera otsiriza | zipangizo zambiri zamagetsi | zipangizo zambiri zamagetsi |
Kuti mumve kusiyana pakati pa MP3 ndi FAC-mafayilo, muyenera kukhala ndi khutu lapadera la nyimbo, kapena "audio". Kuti mumvetsere nyimbo panyumba kapena pamsewu, ma MP3 ali oposa, ndipo FLAC amakhalabe oimba, a DJs ndi a audiophiles.
