Pehea e wehe, hoʻololi, a hoʻololi i nā pūnaewele AMR
ʻO kahi pūnaewele me ka lālā o ka pūnaewele AMR,ʻo ia keʻano o ka waihona o ka ACC Code Codec Multi-Rate. ACELP kahi'ōlelo haʻahaʻa leo leo kanaka kanaka algorithm e kū nei no ka Algebraic Code Excited Linear Prediction.
No laila, Adaptive Multi-Rate kekahi mea hoʻohana i hoʻohanaʻia no ka hoʻopiliʻana i nā leo leo e kālai'ōlelo nuiʻia ana, e like me nā leo leo leo leo a me nā noi VoIP .
No ka hoʻohaʻahaʻaʻana i ka hoʻohana bandwidth ināʻaʻohe leo kani i loko o ka faila, ua hoʻohana ka AMR i nāʻenehana e like me ka Discontinuous Transmission (DTX), Comfort Noise Generation (CNG), a me kaʻikeʻana i kaʻike Voice (VAD).
Mālamaʻia nā faila AMR ma kekahi o nā papahanaʻelua e pili ana i ke alapine. ʻOi keʻano a me ka palena manawa kiko'ī no ka file AMR no kēia. Nui aʻe nā mea ma lalo.
Hoʻomaopopo:ʻO ka AMR kekahi pahu mele no ka mea hoʻopuka o ka mea hoʻolaha a me ka leo / modem riser (kahi hoʻouluʻana ma kahi motherboard ), akāʻaʻohe mea e pili ai i ka hō'ālua o nā faila o nā Adaptive.
Pehea e pāʻani ai i kahi pūnaewele AMR
Hiki i nā mea kani a me nā wikiō makemakeʻia e wehe i nā faila AMR ma kahi paʻamau. Loaʻa kēia i VLC, AMR Player, MPC-HC, a me QuickTime. E kiʻi i kahi polokalamu AMR me Windows Media Player i ka polokalamu K-Lite Codec Pack.
ʻO ka Audacity ka mea hoʻoponopono leo leo ma ka leo mele akā e kākoʻo anaʻo ia i ka hoʻokaniʻana i nā faila AMR, a pēlā nō, ua loaʻa iā ia ka pōmaikaʻi hou o ka weheʻana i ka leo AMR.
ʻO kekahi o Apple, Android a me BlackBerry pūnaewele hoʻokumu pono i nā kōnae AMR, a no laila e hiki iā lākou ke hoʻokani iā lākou me kaʻole o kahi polokalamu kūikawā. Eia kekahi laʻana, kekahi mau polokalamu a me nā polokalamu pilikino e hoʻohana i ka hōʻailona AMR no nā leo leo (ʻo ka BlackBerry 10, keʻano, hikiʻole ke wehe i nā kōnae AMR).
Pehea e hoʻololi ai i kahi AMR Kōnae
Inā heʻano liʻiliʻi ka pūnaewele AMR, makemake wau e hoʻohana i ka mea hoʻololi punaewele pūnaewele . ʻO ka pūnaewele AMR maikaʻi loa pahaʻo ia ka FileZigZag no ka mea hiki iā ia ke hoʻololi i ka file i MP3 , WAV , M4A , AIFF , FLAC , AAC ,' OGG , WMA , a me nā palapala'ē aʻe me kaʻole e lawe i ka polokalamu i kāu kamepiula.
ʻO kekahi koho no ka hoʻololiʻana i kahi waihona AMR he media.io. E like me FileZigZag, media.io holo i loko o kāu pūnaewele pūnaewele. E kau wale i ka waihona AMR ma laila, e haʻi i ka hōpili e makemake anaʻoe e hoʻohuliʻia i, a laila e kiʻi i ka'ōnaehana hou i kāu kamepiula.
Ma waho aʻe o ka AMR Player mai luna mai, hikiʻole ke pāʻani wale i nā mele a me ka hoʻololiʻana i nā mele AMR, he lima wale nō o nā AMR converter e hiki ke hoʻouka .
Hoʻopuka: Hoʻokahi papahana i haʻiʻia i loko o kēia mau mea huli ma AMR o Freemake Audio Converter, akāʻo ka hui e hoʻopuka ana i kēlā papahana, ua kapaʻiaʻo Freemake Video Converter . Ke haʻi aku nei au i kēia papahana no ka meaʻo ia i kapaʻia he mea hoʻololi wikiō wikiō,ʻo ia hoʻi ke kākoʻo i ka hōʻailona AMR. Hiki ke hōʻoia i ka mea e pono ai ka wā e hiki mai ana inā makemakeʻoe e hoʻololi i kahi faila wikiō.
Nāʻike hou aku ma nā pūnaewele AMR
ʻO kekahi kōnae AMR i loko o kekahi o kēia mau palapala: AMR-WB (Wideband) aiʻole AMR-NB (Narrowband).
Hoʻolahalaha nā Multi-Rate - WideBand pūnaewele (AMR-WB) i ke alapine o 50 Hz i 7 Khz a me nā hoʻolālā pāʻani o 12.65 kbps a 23.85 kbps. Hiki iā lākou ke hoʻohana i ka extension file AWB ma mua o AMR.
Aia naʻe nā waihona AMR-NB i ka lihi liʻiliʻi o 4.75 kbps i ka 12.2 kbps a hiki ke hoʻopau i .3GA hoʻi.
Hiki iāʻoe ke wehe i kāu Kōnae?
Inā hikiʻole iāʻoe ke hōʻoia i kāu faila e hāmama me nā manaʻo mai luna nei, e pālua-kelepili e heluhelu anaʻoe i ke kūnaewele pololei. He mea maʻalahi e hoʻololi iā ia me ka mea kānalua like, akā naʻe likeʻole nā hoʻopili pūnaewele like me nā pūnaewele pūnaewele a iʻole hiki iā lākou ke hoʻohanaʻia me nā mea pono pūnaewele like.
Eia kekahi laʻana, nānā ka nānāʻana o ka pūnaewele AMP ma kahi kūlana weliweli e like me AMR akāʻaʻole i pili iki. E hahai i kēlā loulou e aʻo hou e pili ana i nā waihona AMP ināʻo ia ka hōpili file e pili neiʻoe.
ʻO kekahi mau papa'ē aʻe i hiki ke hoʻopiliʻia e like me ka AMR pūnaewele me AMC (AMC Video), AML (ACPI Machine Language), AM (Automatic Makefile Template), AMV (Anime Music Video), AMS (Adobe Monitor Setup) a me AMF ( Hana Hana Hana).
Ma muli o ka hoʻonohonohoʻana o ka AMR ma ke kaomi 3GPP, 3GA kahi kahi hoʻopili pūnaewele e hiki ke hoʻohana i kēia hōpili. ʻOiaiʻo 3GA hoʻohanaʻia no ka leo, mai hoʻololi iā ia me ke kikowaena 3GP video container.
Ma waho aʻe o ia mea, a no ka hōʻano houʻana i nā waihona, nā AMR-WB pūnaewele e hoʻopau ana me AWB, ua like like me ka'ōkuhiʻana i nā faila AWBR e kākauʻia ana me nā kākau TextOnline WordBar i hoʻohanaʻia me Clicker. Eia hou,ʻaʻohe mea e pili ana i kēia mau papahana me nā mea'ē aʻe aʻaʻole hana pū me nā mea like.
