MP3, AAC, WMA, FLAC, ALAC, WAV, AIFF a me PCM i weheweheʻia
ʻO ka hapanui o nā polokalamu e hiki ke hoʻokani i nā kiʻi likeʻole o nā'ōnaehana kikohoho nui mai ka pahu mai, pinepineʻole me kahi polokalamu i makemakeʻia a me nā loli hou. Ināʻoe e hāhi i ke manual huahelu, hiki iāʻoe ke kahaha i ka nui o nāʻano likeʻole.
He aha ka mea eʻokoʻa ai kekahi i kekahi, a he mea nui ia iāʻoe?
Hōʻikeʻia nā Hōʻike Kōnae Pelenae
Ke hele mai nei i ka mele puʻupuʻu , pono maoli ka hōpili? Eia ka pane: ua kū.
Loaʻa nā faila leo hoʻokūkū a me nā'ōlelo kīnāʻole , i loaʻa paha he maikaʻiʻole aʻaʻole paha i nele. Hiki i nā'ōpili luliʻole ke nui i ka nui, akā inā loaʻa i kahi waihona (e like me, PC a pāpale pona paha, pūnaewele paena kikowaena, kahu hānai pūnaewele, a me nā mea'ē aʻe), a iāʻoe nā mea kani iʻoi aku ka kiʻekiʻe, loaʻa nā kōkua i ka hoʻohanaʻana i ka leo .
Akā inā loaʻa ka hakahaka ma ke kumukūʻai, e like me nā smartphones , nā papa, a me nā mea leka uila, a iʻoleʻoe e noʻonoʻo e hoʻohana i nā pepeiao pepeiao a'ōlelo paha, a laila,ʻo nā'ōnaehana hoʻopihapiʻi liʻiliʻi ka nui wale nō.
Peheaʻoe e koho ai? Eia ka mahele o nāʻano maʻamau maʻamau, kekahi o ko lākou mauʻano nui, a me nā kumu e hoʻohana aiʻoe iā lākou.
- MP3: Hoʻolālāʻia e ka Hui Moʻomanaʻo Moving (MPEG), he hui e hoʻolālā i nā hae no nā'ōnaehe leo a me nā wikiō,ʻo ka MPEG-1 / MPEG-2 Layer 3 (MP3) he mea hōʻoia keʻano likeʻole o nā faila leo leo.
- ʻO MP3 he pepa leo hōʻole a me kaʻole , me nā lihi liʻiliʻi e piʻi ana mai ka 8 kbit / s a hiki i 320 kbit / s, a me nā laina frequencies mai ka 16 kHz a hiki i ka 48 kHz. ʻO nā kiʻi liʻiliʻi liʻiliʻi o nā MP3,ʻo ia ka hoʻololi wikiwiki i ka hoʻololiʻana a me ka liʻiliʻi o ka māhele i hoʻohanaʻia, akā, ma ka uku o ke emiʻana i ka maikaʻi o ke kani ke hoʻohālikelikeʻia i nā hōpili file lossless.
- AAC: Ua kaulana i ka Apple iTunes, ua like keʻano o ka hōʻailona Coding Audio (AAC) i ka MP3, akā me ka uku hou iʻoi aku ka maikaʻi.
- ʻO ka AAC he hōpili leo paʻakikī a paʻakikī, me nā lihi liʻiliʻi e piʻi ana mai ka 8 kbit / s a hiki i ka 323 kps / s maximum, a me nā alapine kiʻi e piʻi ana mai ka 8kHz a hiki i ka maximum-me ke kaʻina o nā hoʻopā'ālua pono o 96 kHz.
- Hiki i nā kōnae AAC ke hoʻopiʻi i kaʻoluʻolu leo likeʻole ma MP3 me ka laweʻana i kahi hakahaka liʻiliʻi. Kākoʻoʻo ACC i nā kaha he 48,ʻoiaiʻo ka nui o nā waihona MP3 hiki ke mālama wale iʻelua. Hoʻomaopopo kūlikeʻia ka AAC me kaʻole i kau palenaʻia i nā iOS, Android, a me nā mea hana pāʻani pūʻali.
- WMA: Hoʻokumuʻia e Microsoft ma keʻano he mea hoʻokūkū i ka MP3, nā faila Windows Media Audio ke hāʻawi aku i kahi kūlike likeʻole. ʻO ka WMA maʻamau he hōpili leo a paʻaʻole,ʻoiai nā mea hou, nā unuhi likeʻole me nā codecs keu aku hiki ke hāʻawi i kahi koho kohoʻole.
- ʻOiaiʻo ka nui o nāʻano media media a me nā mea hoʻokipa hale e hāpai i nā faila WMA ma kahi paʻakikī, nā mea likeʻole e like me nā smartphones a me nā papa. He nui nā mea e noi ana e hoʻouka i kahi polokalamu pili pono e hiki ai ke pāʻani i ka audio WMA, hiki ke hoʻolilo ia mea i mea kūponoʻole e hoʻohana me MP3 a iʻole AAC.
- FLAC: Ua hoʻolālāʻia e ka Xiph.Org Foundation, keʻoni kūponoʻoleʻo Audio Codec (FLAC) ma muli o kona laikiniʻole me ka weheʻole.
- ʻO ka FLAC he hōpili leo paʻakikī a me kaʻole, me ka maikaʻi o ka file i hiki i ka 32-bit / 96 kHz (ma ka hoʻohālikelike, he 16-bit / 44.1 kHz ka CD). Hōʻoluʻoluʻo FLAC i ka nui o ka waihona file (e pili ana i 30 a 40% ka liʻiliʻi ma mua o kaʻikepili pilikino) me kaʻole e mōhai i ka leo leo,ʻo ia ka mea e lilo ai i mea hilinaʻi no ka hoʻopaʻaʻana i nā kiʻi (e like me ke kope kope i mea e hana ai nā waihona koi / hapa kūpono no ka hoʻoloheʻana āpau).
- ʻO ka ALAC:ʻO ka Apple's version of FLAC, ka Apple Codeless Audio (ALAC) nui loa e pili ana i ka leo leo a me ka nui kōnae me FLAC.
- ʻO ka ALAC he hōpili leo pa'ū a paʻaʻole. Ua kākoʻo nuiʻiaʻo ia e nā polokalamu iOS a me iTunes,ʻoiaiʻaʻole e kākoʻoʻiaʻo FLAC. No laila, hoʻohana nuiʻia ka ALAC e ka poʻe hoʻohana i nā hua Apple.
- WAV: Ua hoʻolālāʻia e Microsoft,ʻo ka Waveform Audio File Format he standard no nā papahana Windows a paʻakikī hoʻi me nā'ōnaehana polokalamu.
- Hikiʻole ka WAV (akā hiki ke hoʻololiʻia e like me ka hoʻopihaʻia) a me ka leo leoʻole, he kope pololei o kaʻike kumu. Hiki i nā hui pākahi ke hāpai i kahi nui o ka māhele, e hoʻonui i ka paʻi no ka hoʻopaʻaʻana a me ka hoʻoponopono leo. Ua like nā pūnaewele WAV me nā waihona leo pūnaewele PCM a me'AIFF.
- AIFF: Ua hoʻokumuʻia e Apple,ʻo kaʻenehana Kōnae Interchange (AIFF) kahi kumu no ke mālamaʻana i nā leo ma nā kamepiula Mac.
- ʻO ka AIFF iʻole i hoʻokauʻia (kahi'ē aʻe kekahi) a me ka leo leoʻole. E like me ka'ōnaehana WAV o Microsoft, hiki i nā faila AIFF ke mālama i kahi hanana loli maʻamau, e hana maikaʻi ai no ka mālamaʻana a me ka hoʻoponoponoʻana.
- PCM: Ua hoʻohanaʻia i nā hōʻailona ana o ka hoʻohālikelikeʻana,ʻo ka pulina Code Modulation (PCM).
- ʻO ka PCM he hōpili leo paʻakikīʻole a me kaʻole, e hana pinepine ana e like me kaʻike punaewele no ka hanaʻana i nāʻano faila'ē aʻe.
