Ngokuqala kobuchwepheshe bedijithali emhlabeni wezomculo, kuphakame umbuzo wokukhetha izindlela zokwenza iidijithali, ukucubungula kanye nokugcina umsindo. Izindlela eziningi zakhiwe, eziningi zazo ezisetshenziswa ngokuphumelelayo ezimweni ezahlukahlukene. Ngokomhlangano, ahlukaniswe ngamaqembu amakhulu amabili: okulahlekile okulahlekile nokulahlekelayo. Phakathi kwalokho okwedlule, ifomethi yeFCAC ihola phambili; phakathi kwabokugcina, lo monopoly wangempela uye ku-MP3. Ngakho-ke yimuphi umehluko omkhulu phakathi kwe-FLAC ne-MP3, futhi abalulekile yini kumlaleli?
Yini i-FLAC ne-MP3
Uma umsindo urekhodwa ngefomethi ye-FLAC noma uguqukele kukho usuka kwelinye ifomethi engenakho ukulahleka, yonke imbonakalo yemvamisa nemininingwane eyengeziwe ngokuqukethwe kwefayela (imethadatha) kuyagcinwa. Isakhiwo sefayela simi ngokulandelayo:
- izintambo ezine zokuhlonza (i-FlaC);
- I-Streaminfo metadata (edingekayo ukulungiselela imishini yokudlala);
- Ezinye izivimba zemethadatha (ngokuzithandela)
- ozimele bomsindo.
Kuyinto ejwayelekile ukurekhoda ngokuqondile amafayela e-FLAC ngenkathi udlala umculo obukhoma noma kumarekhodi we-vinyl.

Lapho kuthuthukiswa ubuchule obuphezulu bokucindezela amafayela we-MP3, imodeli yengqondo yomuntu yathathwa njengesisekelo. Kalula nje, ngesikhathi sokuguqulwa, lezo zingxenye zesikhonkwane ukuzwa kwethu okungaboni noma ezingakuboni ngokuphelele 'kuzonqanyulwa' ekusakazweni komsindo. Ngaphezu kwalokho, ngokufana kwemifudlana ye-stereo ezigabeni ezithile, zingashintshwa zibe ngumsindo we-mono. Isilinganiselo esikhulu sekhwalithi yomsindo izinga lokucindezela - isilinganiso esincane:
- kuze kufike ku-160 kbit / s - ikhwalithi ephansi, ukuphazamiseka okuningi okuvela eceleni, ukuphindaphindeka kwe-frequency;
- I-160-260 kbit / s - ikhwalithi ephakathi, ukukhiqizwa okuphakathi kwe-frequocre of frequency peak;
- 260-320 kbit / s - ikhwalithi ephezulu, umfaniswano, umsindo ojulile nobuncane bokuphazanyiswa.
Kwesinye isikhathi i-bitrate ephezulu itholakala ngokuguqula ifayili le-bitrate eliphansi. Lokhu ngeke kulithuthukise ikhwalithi yomsindo nganoma iyiphi indlela - amafayela aguqulwe kusuka ku-128 aye ku-320 bit / s asazwakala njengefayela le-128-bit.
Ithebula: Ukuqhathanisa kwezimpawu nokwehluka kwezindlela zokulalelwayo
| Isikhombi | Flac | Izinga eliphansi le-MP3 | Phezulu bitrate mp3 |
| Isimo sokucindezela | ukulahleka | ngokulahleka | ngokulahleka |
| Ikhwalithi yomsindo | phezulu | ephansi | phezulu |
| Umthamo wengoma eyodwa | 25-200 Mb | 2-5 Mb | 4-15 Mb |
| Ukuqokwa | lalele umculo kwizinhlelo zekhwalithi ezisezingeni eliphezulu, wakhela umlando wokugcina umculo | ukusetha ukuncenceza, ukugcina nokudlala amafayela kumadivayisi anamemori ekhawulelwe | ukulalela ekhaya umculo, ukugcinwa kukhathalogu kumadivayisi aphathwayo |
| Ukuvumelana | Ama-PC, amanye ama-Smartphones kanye namathebulethi, abadlali abasezingeni eliphezulu | imishini eminingi kagesi | imishini eminingi kagesi |
Ukuze uzwe umehluko phakathi kwe-MP3 yekhwalithi ephezulu nefayela le-FLAC, udinga ukuthi ube nendlebe evelele yomculo noma uhlelo lomsindo “oluthuthukile”. I-MP3 yanele ngokwanele ukulalela umculo ekhaya noma usohambeni, futhi i-FLAC isalokhu inabaculi abaningi, ama-DJs nama audi audiles.
