Indlela Yokuvula, Hlela, kwaye Uguqule Iifayile ze-AMR
Ifayile enefayile ye-AMR isandiso se-ACELP Codec ye-Multi-Rate Multi-Rate. I-ACELP yintetho ye-algorithm yomsindo womntu omela i-Algebraic Code Code Excited Linear Prediction.
Ngoko ke, i-Adaptive Multi-Rate yi-teknoloji yoxinzelelo esetyenziselwa ukufowunela iifayile zomsindo ezibhekiselele kwi-intetho-based, njengeefowuni yokurekhoda kwezwi kunye ne- VoIP izicelo.
Ukunciphisa ukusetyenziswa kwebhenwidth xa kungekho nomahluko odlala kwifayili, ifomathi ye-AMR isebenzisa ubuchwephesha njenge-Transcontinous Transmission (DTX), i-Noise Generation (CNG), kunye nokuThola umsebenzi wezwi (VAD).
Iifayile ze-AMR zigcinwa kwisinye sezifomathi ezimbini ngokuxhomekeka kwinqanaba lexesha. Indlela kunye nokongezwa kwefayili ethile yefayile ye-AMR ingahluka ngenxa yale nto. Kukho ngaphezulu kwizantsi.
Qaphela: i- AMR nayo isingqamaniso somyalezo weejenti yomlayezo kunye nomsindo wemodemu / i-modem riser (isandiso sokwandisa kwibhodi ye- motherboard ), kodwa ayinanto enxulumene nefomathi yefayile ye-Adaptive Multi-Rate.
Ukudlala njani iFayile ye-AMR
Abaninzi abadlali abalalelwayo / bevidiyo baza kuvula iifayile ze-AMR ngokuzenzekelayo. Oku kubandakanya i-VLC, i-AMR Player, i-MPC-HC kunye ne-QuickTime. Ukudlala ifayile ye-AMR ngeWindows Media Player ingafuna i-K-Lite Codec Pack.
Ukuphicothwa kwengxelo kubaluleke kakhulu kumhleli womsindo kodwa kuxhasa ukudlala iifayile ze-AMR, ngoko ke, kunenzuzo eyongeziweyo yokuvumela ukuba uhlele i-AMR audio kunye.
Ezinye iifayile ze-Apple, i-Android, kunye ne-BlackBerry zenza iifayile ze-AMR nazo, kwaye ngoko kufuneka zikwazi ukuzidlala ngaphandle kwenkqubo ekhethekileyo. Ngokomzekelo, ezinye iifayile ze-Android kunye ne-BlackBerry zisebenzisa iifom ye-AMR yokurekhoda kwezwi (i-BlackBerry 10, ngokukodwa, ayikwazi ukuvula iifayile ze-AMR).
Indlela yokuguqula ifayile ye-AMR
Ukuba ifayile ye-AMR incinci kakhulu, ndincoma ukusebenzisa i- converter ifayile ye- intanethi. I-converter engcono kakhulu ye-AMR i- FileZigZag kuba iyakwazi ukuguqula ifayile kwi- MP3 , WAV , M4A , AIFF , FLAC , AAC , i- OGG , i- WMA kunye nezinye iifom ngaphandle kokuba ukhuphe isofthiwe kwikhompyuter yakho.
Enye indlela yokuguqula ifayile ye-AMR ngu media.io. NjengoFayileZigZag, i-media.io isebenza ngokupheleleyo kwisiphequluli sakho sewebhu. Mane ulayishe ifayile ye-AMR apho, xelela ifomathi ofuna ukuba iguqulwe kuyo, kwaye ukhupha iifayile entsha kwikhompyutha yakho.
Ukongeza kwi-AMR Player esuka phezulu, engenakudlala kuphela kodwa ukuguqula iifayile ze-AMR, ininzi yezinye iinguqulelo ze-AMR ezingayilandwa .
Iphulo: Enye inkqubo ekhankanywe kulabo baguquliweyo be-AMR abaguquleli yi-Freemake Audio Converter, kodwa inkampani ehambisa loo nkqubo inokwenza i-Freemake Video Converter . Ndiyathetha le nkqubo kuba ngelixa liqwalaselwa ngokutsha njengenguqu yefayile yefayile, ikwaxhasa kwakhona ifomathi ye-AMR. Ukuyilanda kunokuba luncedo kwixesha elizayo ukuba ufuna ukuguqula ifayile yevidiyo.
Ulwazi oluthe xaxa kwiifayile ze-AMR
Naliphi na ifayile ye-AMR kwenye yale fom: AMR-WB (Wideband) okanye i- AMR-NB (Narrowband).
Iifayili ezininzi ze-Adaptive - iifayile ze-WideBand (AMR-WB) zixhasa i-frequency range ye-50 Hz ukuya kwi-7 Khz kunye namaxabiso angama-12.65 kbps ukuya kuma-23.85 kbps. Basenokusebenzisa isandiso sefayile ye-AWB esikhundleni se-AMR.
Iifayile ze-AMR-NB, nangona kunjalo, unomlinganiselo omncinane we-4.75 kbps ukuya kwi-12.2 kbps kwaye unokuphela .3GA.
Usenokukwazi & # 39; ukuvula ifayile yakho?
Ukuba unganakwenzeka ukuba ufumane ifayile yakho ukuvula kunye neziphakamiso ezivela ngasentla, qwa lasela ukuba ufunda isandiso sefayile ngokuchanekileyo. Kulula ukuyidibanisa kunye nesipelingi esifanayo, kodwa ukwandiswa kwefayile efanayo akuthethi ukuba ifomathi yefayile zifana nokuba zingasetyenziswa kunye nezixhobo ezifanayo zesofthiwe.
Ngokomzekelo, isandiso sefayile ye- AMP sibonakala kunzima kakhulu njenge-AMR kodwa ayinxulumene ncinane. Landela loo nxu luze ufunde kabanzi malunga neifayile ze-AMP ukuba yiyo ifomathi yefayile oyenzayo.
Ezinye iifayile ezongeziweyo ezinokudideka njengefayile ye-AMR iquka i-AMC (i-AMC Video), i-AML (ulwimi lwe-ACPI yolwimi), AM (i-Automake Makefile Template), i-AMV (i-Anime Music Video), i-AMS (i-Adobe Monitor Setup) kunye ne-AMF ( Ukwenziwa koKongeza).
Ekubeni ifomathi ye-AMR isekelwe kwifomathi ye-3GPP yenkomfa, i-3GA enye isandiso sefayile kule fom ingayisebenzisa. Nangona i-3GA isetyenziselwa ukuvakala, musa ukudibanisa nefomathi yevidiyo ye- 3GP .
Ukongeza koko, kwaye ukwenza konke kudideke ngakumbi, iifayile ze-AMR-WB eziphela nge-AWB, ziyafana ngokupela isipelo kwiifayile ze-AWBR ezibhalwe kwiifayile ze-WordBar ezibhalwe kwi-WordBar kunye neClicker. Kwakhona, ifomathi zombini ayinanto yokwenza kunye kwaye ayisebenzi kunye nezicelo ezifanayo.
