MP3, AAC, WMA, FLAC, ALAC, WAV, AIFF, kunye ne-PCM ichazwe
Uninzi lwezixhobo ziyakwazi ukudlala iindidi ezahlukeneyo zedijithali zefayile ngaphandle kwebhokisi, ngokuqhelekileyo ngaphandle kwesoftware efunekayo okanye i-firmware updates. Ukuba uhamba ngeqhosha lomkhiqizo unokumangaliswa yimiba eyahlukeneyo.
Yintoni eyenza bahluke komnye, kwaye oku kufanelekile kuwe?
Iifom zeFayile zeMculo ezichazwe
Xa kuziwa kumculo wedijithali , ngaba ifomathi ibaluleke kakhulu? Impendulo kukuba: kuxhomekeke.
Kukho iifayile zomsindo ezixinyiweyo kunye ezingapheliyo, ezinokuthi zilahleke okanye zilahleke. Iifayile ezingalahlekanga zinokuba zikhulu ngobukhulu, kodwa ukuba zinokugcinwa okuninzi (umzekelo, i-PC okanye i-laptop, umgca wokugcina inethiwekhi, iseva yemidiya, njl.), Kunye nezixhobo zomsindo ophezulu, zikhona iinzuzo zokusebenzisa i-audio incompressed okanye ilahleko .
Kodwa ukuba indawo iphezulu, njengama- smartphones , iipilisi, kunye nabadlali abaphathekayo, okanye uceba ukusebenzisa i-headphones okanye izithethi ezisisiseko, iifayile ezincinci ezincinci ziyakudinga zonke.
Ukhetha njani? Nantsi ukuphazamiseka kwezifomathi eziqhelekileyo, ezinye zeziganeko ezibalulekileyo, kunye nezizathu zokuba ungayisebenzisa.
- I-MP3: Yenzelwe iQela leeNkcukacha zeMifanekiso ye-Moving (MPEG), inhlangano eyenza imilinganiselo yeenkqubo zomsindo kunye nevidiyo, i-MPEG-1 / MPEG-2 Layer 3 (MP3) ngokuqinisekileyo uhlobo oluthile oluxhasayo nolwasetyenzisiweyo lwefayile.
- I-MP3 yinkomfa yomsindo ogxininisiweyo kunye nelahleko , kunye namaxabiso amanani ukusuka kwi-8 kbit / s ukuya kuma-320 kbit / s, kunye neempatho zepampu ezivela kwi-16 kHz ukuya kuma-48 kHz. Ubuncinane befayili yee-MP3s kuthetha ukutshintshwa kwefayili ngokukhawuleza kunye nesithuba esingaphantsi esisetyenzisiweyo, kodwa ngexabiso lokunciphisa umgangatho wezandi xa kuthelekiswa namafomathi efayili.
- I-AAC: Yenziwe ithandwa yi-iTunes ye-Apple, ifomathi ye- Advanced Audio Coding (AAC) ifana ne-MP3, kodwa enye inzuzo eyongeziweyo yokusebenza kakuhle.
- I-AAC yinkomfa yomsindo ogxininisiweyo kunye nelahleko, ukusuka kuma-8 kbit / s ukuya kuma-320 kbit / s, kunye neesampuli ezibonisa ukususela kwi-8 kHz ukuya kwi-maximum-process-encoding process-96 kHz.
- Iifayile ze-AAC ziyakwazi ukuhambisa ikhwalithi efanayo yomculo njenge- MP3 ngelixa lithatha indawo encinane. I-ACC iphinde isekele kwizithuba ezingama-48, ngelixa ezininzi iifayile ze-MP3 zingabamba ezimbini kuphela. I-AAC iyahambelana ngokubanzi kodwa ingaphelelwanga kwi-iOS, i-Android, kunye nezixhobo zokudlala ezigcinwe ngesandla.
- I-WMA: Ephuhliswe nguMicrosoft njengomncintiswano kwi-MP3, iifayile ze- Windows Media Audio zinikeza amava afanayo, nangona kunjalo. I-WMA esemgangathweni ibini ifomati yokuxinwa kunye nelahleko, nangona i-entsha, iinguqulelo ezihlukileyo kunye neenkodec eziphambili zinganikela ngenjongo yokulahlekelwa.
- Nangona iindidi ezininzi zeendaba eziphathekayo kunye nabadlali bokuzonwabisa bekhaya baxhasa iifayile zeWMA ngokuzenzekelayo, ezimbalwa izixhobo eziphathekayo ezifana ne-smartphones kunye namacwecwe. Abaninzi badinga ukukhuphela iprogram ehambelanayo ukuze udlale i-WMA audio, engenza kube lula ukuba usebenzise i-MP3 okanye i-AAC.
- I-FLAC: Ephuhliswe yiSiseko se-Xiph.Org, i- Free Lossless Audio Codec (FLAC) inokhenketho olukhulu ngenxa yelayisenisi yayo yokukhululeka kunye nefomati evulekile.
- I-FLAC ibini ifomati yokucetyiswa kunye nelahleko, kunye nekhwalithi yefayile ekwazi ukufikelela kuma-32-bit / 96 kHz (ngokuthelekisa, i-CD ibinama-16-bit / 44.1 kHz). I-FLAC inomdla wokunciphisa ubungakanani befayili (malunga ne-30 ukuya kuma-40 ekhulwini kwincinci kunedatha yangaphambili) ngaphandle kokunikela umgangatho wokulalelwayo, okwenza kube yindawo efanelekileyo yokugcinwa kwe-digital (oko kukuthi, ukuyisebenzisa njengengxelo yekhowudi ukuze udale iifayile ezixinzelelweyo / ezilahlekileyo ukuphulaphula ngokubanzi).
- I-ALAC: Inguqulelo ye-Apple ye-FLAC, i-Apple Lossless Audio Codec (ALAC) inokwabelana ngokubhekiselele kumgangatho womculo kunye nefayile yeFAC.
- I-ALAC yinkomfa yomsindo ogxininisiweyo kunye nelahleko. Kukwaxhaswa ngokupheleleyo ngamadivayisi e-iOS kunye ne-iTunes, kanti i-FLAC ayinakuxhaswa. Ngaloo ndlela, i-ALAC yayiqhelekileyo isetyenziswe ngabantu basebenzisa iimveliso ze-Apple.
- I-WAV: Kwakhiwa kunye ne-Microsoft, i-Waveform Ifayile yeFayile ye-Audio yinkqubo ye-Windows-based based systems kwaye iyahambelana neentlobo zezicelo zesofthiwe.
- I-WAV ibinakunyanzelwanga (kodwa inokudibaniswa njengekhompressed) kunye nefomathi yomsindo olahlekileyo, ngokukodwa ikopi echanekileyo yedatha yomthombo. Iifayili zomntu ngamnye zingathabatha inani elikhulu lezithuba, okwenza ifomathi ibe yindawo efanelekileyo yokugcinwa kwirekhodi kunye nokuhlelwa komsindo. Iifayile zomsindo we-WAV zifana neefayile zeefayile ze-PCM kunye ne-AIFF.
- I-AIFF: Kwakhona iveliswe yi-Apple, iFayili yokuTshintshana kweFayile ye-Audio (AIFF) ngumgangatho wokugcina umsindo kwiikhompyutha ze-Mac.
- I-AIFF yinto engagxininiswayo (kukho i-variant compressed) kunye nefomathi yomsindo olahlekileyo. Njengofomathi yefayile ye-Microsoft ye-VV, iiFayili ze-AIFF zingathatha indawo eninzi yokugcinwa kwedijithali, okwenza kube ngcono ukugcinwa kwirekhodi nokuhlela.
- I-PCM: Isetshenziselwa ukuba imele imiqondiso ye-analog, i-Pulse Code Modulation (i-PCM) ifom yefayile ye-CD, kodwa nakwiikhomputha kunye nezinye izicelo zomsindo we-digital.
- I-PCM yinto engabonakaliyo kunye nefomathi yomsindo olahlekileyo, ngokuqhelekileyo isebenza njengedatha yomthombo wokudala ezinye iintlobo zeefayile zomsindo.
