Eʻike i nāʻano faila pūnaewele e hana nei &ʻaʻole e hana i ka iPhone a me ka iPod
I ka manawa o ke mele pūnaewele, pinepine ka poʻe i kelepona i kahi mele mele "MP3." Akā,ʻaʻole i pololei. MP3 e pili ana i kahiʻano kiko'ī o ka leo leo aʻaʻoleʻo kēlā me kēia leo leo pilikinoʻoiaʻiʻo he MP3. Inā hoʻohanaʻoe i kekahi iPhone , iPod, aiʻole kekahi mea Apple, aia kahi kūpono e hikiʻole i ka hapa nui o kāu mele i loko o ka MP3 MP3.
He aha keʻano o ka faile i kāu mau mele mamoe, a laila? Hōʻike kēiaʻatikala i nā kiko'ī o ka filetype MP3, kaʻoi aʻe o Apple a me ka Apple-i makemakeʻia, a me kekahi o nāʻano pūnaewele leo likeʻole e hana aʻaʻole e hana pū me iPhones a me nā iPod.
Nā mea apau e pili ana i ka MP3 Format
MP3 no ke kele MPEG-2 Audio Layer-3, he papahana media media e hoʻohālikeʻia e ka Group Experts Group (MPEG), he kinoʻoihana e hana i nā papahanaʻoihana.
Pehea MP3s Mahi
Hoʻokumuʻia nā mele i hoʻolakoʻia ma ka MP3 format e kiʻi i ka liʻiliʻi ma mua o nā mele likeʻole e hoʻohanaʻia me ka hoʻokanikani leo leo CD e like me WAV (ʻoi aʻe ma kēlā puka ma hope). ʻO nā mele mele i loko o MP3s,ʻo ia ka weheʻana i nāʻaoʻao o ka pūnaewele iʻole e pili i kaʻike hoʻolohe,ʻo ia hoʻi ka hopena kiʻekiʻe loa o ka leo. Ma muli o kahi wehe 'ia o nā'ilipili,' aʻole hoʻokani 'ia MP3 ma konaʻano CD-quality version a ua kapa' ia he "hōʻailona" pohō . ʻO ka naloʻana o kekahi mau'āpana o ka leo ua hoʻonāukiuki i kekahi mau kāpili mele MP3 no ka hōʻinoʻana i kaʻike hoʻolohe.
Ma muli o ka paʻaʻana o nā MP3 iʻoi aʻe ma mua o ka AIFF aiʻole kekahi mau papa hana hoʻopukaʻole, hiki i nā lako MP3 ke mālamaʻia ma ka like o ka huina kūikawā ma mua o nā faila CD.
ʻOiai nā hoʻololi i hoʻohanaʻia no ka hanaʻana i MP3s hiki ke hoʻololi i kēia, ke'ōlelo nei i kahi MP3 e lawe i kahi o 10% o kahi o kahi leo leo CD maikaʻi. Eia kekahi laʻana, ināʻo ka version CD-quality o kahi mele he 10 MB,ʻo ka'ōnaehana MP3 ma kahi o 1 MB.
Nā Bit Bit a me MP3s
Hoʻoleonaʻia ka leo leo o MP3 (a me nā pūnaewele puʻupuʻu pūnaewele) e ka lihi lihi, i hāʻawiʻia e like me kbps.
ʻO ka kiʻekiʻe o ka māmā liʻiliʻi,ʻo ka nui o nāʻikepili o ka waihona aʻoi aku ka maikaʻi o nā leo MP3. ʻO ka nui o nā haʻawina likeʻole he 128 kps, 192 kbps, a me 256 kbps.
ʻEluaʻano o nā lihi liʻiliʻi i hoʻohanaʻia me MP3s: Ka Nui Pōkē Kūʻokoʻa (CBR) a me ka Vista Nui Maoli (VBR) . Nui nā'ōlelo MP3 i kēia manawa no ka hoʻohanaʻana i ka VBR, ke hana nei i nā mea liʻiliʻi ma ke kākauʻana i kekahi mau māhele o kahi mele ma kahi liʻiliʻi liʻiliʻi, aʻo nā mea'ē aʻe e hoʻopiliʻia me ka hoʻonuiʻana i nā uku. Eia kekahi laʻana, hiki ke hoʻololiʻia kahi māhele o kahi mele me kahi mea hoʻokahi wale nō a hiki ke hoʻopiliʻia me ka lihi liʻiliʻiʻoi aʻe, aʻo nā māhele o kahi mele me nā mea hana maʻalahi e pono ke emi i ka pāʻani e hopu i keʻano o ke kani. Ma ka hoʻololiʻana i ka lihi liʻiliʻi, hiki ke kū i ke kiʻekiʻe o ke kani kani o MP3 hiki ke mālamaʻia ka mea e pono ai no ka mālamaʻana o ka faila.
Peheaʻo MP3 a me iTunes
MP3 pahaʻo ia ka'enepili punaewele punaha loa i ka pūnaewele, akā,ʻaʻoleʻo ka iTunes Store e hāʻawi aku i ke mele i kēlāʻano (e pili ana i kēlā ma kaʻaoʻao aʻe). ʻOiaiʻo ia, ua pili likeʻo MP3 me iTunes a me nā polokalamu iOS a pau, e like me ka iPhone a me ka iPad. Hiki iāʻoe ke loaʻa MP3s mai:
- Loaʻa nā kiʻi paʻi kiʻi like AmazonMP3 a me eMusic
- Loaʻa nā mele mai ka CD , ma muli o kāu mau hoʻololi hoʻololi mele
- Nui nā lawelawe hoʻoili pūnaewele-pūnaewele.
Nā mea a pau e pili ana i ka papa AAC
ʻO ka AAC, kahi e kū nei i ka Audio Coding Aʻo, heʻano faila leo leo moʻomeheu i hoʻolahaʻia ma keʻano he mea pani i ka MP3. Hoʻonohonoho ka'AAC i ke kani kiʻekiʻe o ka leo ma mua o ka MP3 ma ka hoʻohanaʻana i ka nui o ka māhele mokulele a iʻole ka liʻiliʻi.
Manaʻo ka poʻe he mea kūpono ka Apple AAC ma Apple, akāʻaʻole pololei kēia. Ua hoʻokumuʻia ka AAC e kekahi hui pūʻulu me AT & T Bell Labs, Dolby, Nokia, a me Sony. ʻOiaiʻo Apple i hoʻokomo i ka AAC no kāna mele, hiki ke hoʻokaniʻia nā faila AAC ma nāʻano hanaʻole Apple, me nā consoles pāʻani a me nā pūnaewele pūnaewele e holo ana ma Google OS OS, me nā mea'ē aʻe.
Pehea AAC e hana ai
Like MP3, AAC he hōpili file faili. No ka hoʻokomoʻiaʻana o nā leo CD-maikaʻi i loko o nā waihona e hōʻiliʻili ana i kahi wahi kiko'ī, nāʻikepili iʻole e pili i kaʻike hoʻolohe - hou, i ka manawa ma ke kiʻekiʻe a me ka hope loa. No ka hopena o ka hoʻopilikiaʻana,ʻaʻohe kani leo o nā kōnae AAC i nā faila CD-maikaʻi, akā i keʻano maikaʻi loa no kaʻikeʻoleʻana o nā kānaka i ka manaʻo kaumaha.
E like me MP3s, ua anaʻia ka maikaʻi o kahi waihona AAC ma muli o kona kaʻina bit. ʻO ka AAC Common bitrates pūʻia nā 128 kbps, 192 kbps, a me 256 kbps.
ʻO nā kumu i hoʻolahaʻia ai ka'AAC eʻoi aku ke kani kaniʻoi aʻe ma mua o nā MP3. No kaʻikeʻana e pili ana i nāʻikepili kikohana o kēiaʻokoʻa, e heluhelu i ka mea Wikipedia ma'AAC.
Pehea AAC e hana ai me iTunes
Ua hoʻokomoʻo Apple i ka AAC i konaʻano punaewele punahele no ka leo. ʻO nā mele a pau i kūʻaiʻia ma ka iTunes Store, a me nā mele a pau i kaheʻia aiʻole i laweʻia mai i Apple Music, aia i loko o ka hōʻuluʻulu AAC. ʻO nā palapala AAC i hāʻawiʻia i kēia mauʻaoʻao, ua kāʻeiʻia i 256 kbps.
ʻO ka WAV Audio File Format
He pōkoleʻo WAV no ka Waveform Audio Format. ʻO kēia keʻoni leo leo kiʻekiʻe loa i hoʻohanaʻia no nā noi e makemake ana i ke kani kūpono kiʻekiʻe, e like me nā CD. ʻAʻole pilikia nā kōnae WAV, a no laila lawe i kahi māka mokumahuʻoi aʻe ma mua o MP3 a iʻole AACs, i hoʻopaʻaʻia.
Ma muli o ka pilikiaʻole o nā kōnae WAV (ʻikeʻia hoʻi he "makeless" format ), aia i loko o lākou kaʻikepili hou aʻe a hoʻonui i ka maikaʻi, nāʻoihana maʻalahi, a me nā kiko kiko'ī. ʻO kahi kōnae WAV e pono i 10 MB no kēlā me kēia 1 minuke o ka leo. Ma ka hoʻohālikelike, makemakeʻo MP3 i kahi 1 MB no kēlā me kēia 1 minuke.
Ua loli nā'ōnaehana WAV me nā polokalamu Apple, akā,ʻaʻole i hoʻohana pinepineʻia e hoʻohanaʻia e nā audiophiles. E aʻo hou e pili ana i ka hōʻailona WAV .
ʻO ka WMA Audio File Format
ʻO WMA ke kū nei no Windows Media Audio. ʻO kēia keʻano o keʻano o ka faila i hoʻolaha nuiʻia e Microsoft,ʻo ka hui i hoʻohuiʻia. ʻO ia ka'ōnaehana maoli i hoʻohanaʻia ma ka Windows Media Player, ma nā Macs a me nā PC. Hoʻolālāʻo ia me nā kiʻi MP3 a me AAC a hāʻawi like i ka hoʻokumu a me nāʻano likeʻole e like me kēlā mau papahana. ʻAʻole ia e like me ka iPhone, iPad, a me nā mea like Apple. E aʻo hou e pili ana i ka hōʻailona WMA .
Ka AIFF Audio File Format
ʻO'AIFF kahi e kū nei no ka hoʻokumu pūnaewele Interchange. ʻO kekahi papa mele kiʻiʻole, i hanaʻia e Apple i ka hopena o nā makahiki 1980. E like me WAV, hoʻohanaʻo ia i kahi 10 MB o ka paena i kēlā me kēia minuke o ke mele. Ma muli o kaʻomiʻole o ka waihona mele,ʻo ka AIFF kahi hōʻonui kūpono o ka hōʻailona i makemakeʻia e nā audiophiles a me nā mea hula. Ma muli o ka hana a Apple, ua maʻalahi ia me nā polokalamu Apple. E aʻo hou e pili ana i ka palapala AIFF .
ʻO Apple Lossless Audio File Format
ʻO kekahi mea hou Apple,ʻo Apple Cossc Audio Recordc (ALAC) ka mea pani o AIFF. ʻO kēia huahana, i hoʻokuʻuʻia i ka makahiki 2004, he papahana kūpono ia. Ua weheʻiaʻo Apple i ka waihona i ka makahiki 2011. No ka hoʻopiliʻana o Apple i nā pale kaulike e ho'ēmi ana i ka nui kōnae me ka mālamaʻana i ka maikaʻi o ka maikaʻi. ʻO kona mauʻaoʻao ma kahi o 50% ka liʻiliʻi ma mua o nā kīʻole i hōʻoleʻia, akā me ka emi iho o ka pohō i ka leo leo ma mua o MP3 a iʻole AAC. E aʻo hou e pili ana i ka hōʻailona ALAC .
ʻO ka hoʻonānae Kōnae Pilikino FLAC
Kūkaʻiʻia me nā audiophiles, FLAC (Free Lossless Audio Codec) he hōʻali leo leo open-source e hiki ai ke hoʻemi i ka nui o kahi faila ma o 50-60% me ka hoʻoemiʻole i ka maikaʻi o ka leo.
ʻAʻole hiki i ka FLAC ke hui pū me nā polokalamu iTunes a me nā polokalamu iOS mai loko mai o ka pahu, akā hiki iā ia ke hana me nā polokalamu'ē aʻe i hoʻonohoʻia ma kāu pūnaewele. E aʻo hou e pili ana i ka hōʻuluʻulu FLAC .
