Indlela Yokuvula, Hlela, nokuguqula Amafayela we-AMR
Ifayela elinesandiso sefayili le-AMR ifayela elixhasayo le-ACELP Codec le-Adaptive Multi-Rate. I-ACELP ingu-algorithm yokunciphisa umsindo wezwi lomuntu omelela i-Code Algebraic Exited Linear Prediction.
Ngakho-ke, i-Adaptive Multi-Rate iyinhlangano yobuchwepheshe bokucindezela esetshenziselwa ukufaka ikhodi yamafayela alalelwayo ngokuyinhloko okusekelwe enkulumweni, njengokungathi ukuqoshwa kwezwi lomakhalekhukhwini kanye nezinsiza ze-VoIP .
Ukunciphisa ukusetshenziswa kwe- bandwidth uma kungekho okudlala komsindo efayeleni, ifomethi ye-AMR isebenzisa ubuchwepheshe obufana ne-Discontinuous Transmission (DTX), i-Comfort Noise Generation (CNG), nokuThola umsebenzi wezwi (VAD).
Amafayela we-AMR agcinwa kwesinye sefomethi ezimbili ngokuya kobubanzi bemvamisa. Indlela kanye nesandiso esithile sefayela sefayela le-AMR lingase lihluke ngenxa yalokhu. Kuningi kulokho ngezansi.
Qaphela: i- AMR iphinde isetshenziselwe umlayezo womlayezo we-ejenti kanye nokuphakama komsindo / i-modem ( isandiso sokwandisa ebhodini le- motherboard ), kodwa ayihlangene nhlobo nefomethi yefayili ye-Adaptive Multi-Rate.
Idlalwa kanjani ifayela le-AMR
Abadlali abaningi abalalelwayo / bevidiyo bazovula amafayela we-AMR ngokuzenzakalelayo. Lokhu kuhlanganisa i-VLC, i-AMR Player, i-MPC-HC, ne-QuickTime. Ukudlala ifayela le-AMR nge-Windows Media Player kungadinga i-K-Lite Codec Pack.
Ukuziphendulela kungumhleli womsindo kodwa kusekela ukudlala amafayela we-AMR, ngakho-ke, kunomhlomulo owengeziwe wokukuvumela ukuthi uhlele umsindo we-AMR.
Amanye amadivayisi we-Apple, Android, nama-BlackBerry enza amafayela we-AMR futhi, ngakho-ke kufanele akwazi ukudlala ngaphandle kohlelo lokusebenza olukhethekile. Isibonelo, amanye amadivayisi we-Android ne-BlackBerry asebenzisa ifomethi ye-AMR yokuqopha kwezwi (i-BlackBerry 10, ngokuqondile, ayikwazi ukuvula amafayela we-AMR).
Indlela yokuguqula ifayela le-AMR
Uma ifayela le-AMR lihle kakhulu, ngincoma ukusebenzisa i- converter yamafayela e- inthanethi yamahhala. I-converter engcono kakhulu ye-AMR ku-intanethi mhlawumbe i- FileZigZag ngoba ingaguqula ifayela ku- MP3 , WAV , M4A , AIFF , FLAC , AAC , i- OGG , i- WMA , namanye amafomethi ngaphandle kokulanda isofthiwe kwikhompyutha yakho.
Enye indlela yokuguqula ifayela le-AMR yi-media.io. NjengofayelaZigZag, media.io igijima ngokuphelele kusiphequluli sakho sewebhu. Vele ulayishe ifayela le-AMR lapha, litshele ifomethi ofuna ukuba liguqulwe kuyo, bese ulanda ifayela elisha kukhompyutheni yakho.
Ngaphezu kwe-AMR Player kusuka phezulu, engakwazi ukudlala kuphela kodwa futhi iguqule amafayela we-AMR, iyingxenye yamanye abaguquli be-AMR abangalandwa .
Ithiphu: Uhlelo olulodwa olukhulunywe kulabo abaguqulwayo be-AMR abaguqulwa yi-Freemake Audio Converter, kodwa inkampani ehambisa leyo hlelo yenza futhi okuthiwa i- Freemake Video Converter . Ngikhuluma ngaloluhlelo ngoba ngenkathi kubhekwa njengenguqulo yefayela yevidiyo, ibuye isekele isakhiwo se-AMR. Ukulanda kungase kuzuze esikhathini esizayo uma udinga ukuguqula ifayela levidiyo.
Ulwazi olungaphezulu kumafayela we-AMR
Noma iyiphi ifayela le-AMR lingenye yalezi zakhiwo: AMR-WB (Wideband) noma i- AMR-NB (Narrowband).
Ama-Multi-Rate Adaptive - Amafayela we-WideBand (AMR-WB) asekela ububanzi bamaphesenti ama-50 Hz kuya kuma-Khz nama-bit angama-12.65 kbps kuya ku-23.85 kbps. Bangasebenzisa isandiso sefayela le-AWB esikhundleni se-AMR.
Amafayela we-AMR-NB, noma kunjalo, anenani elilinganiselwa ku-4.75 kbps kuya ku-12.2 kbps futhi angagcina .3GA futhi.
Noma kunjalo Ungakwazi Ukuvula Ifayela Lakho?
Uma ungabonakali ukuthola ifayela lakho ukuvula ngeziphakamiso ezivela phezulu, kabili hlola ukuthi ufunda isandiso sefayela ngendlela efanele. Kulula ukusidibanisa nalowo ophethwe ngokufanayo, kepha izandiso zefayela ezifanayo azisho ukuthi amafomethi wefayela afana nawo noma angasetshenziswa ngamathuluzi esofthiwe afanayo.
Isibonelo, isandiso sefayili se- AMP sibheka izinto ezinzima njenge-AMR kepha azihlobene neze. Landela leso sixhumanisi ukuze ufunde kabanzi mayelana namafayela we-AMP uma ngabe yifomethi yefayili osebenza ngayo.
Ezinye izandiso zefayela ezingahle zidideke njengefayela le-AMR zihlanganisa i-AMC (AMC Video), i-AML (i-ACPI Machine Language), i-AM (i-Automake Makefile Template), i-AMV (i-Anime Music Video), i-AMS (i-Adobe Monitor Setup), ne-AMF ( Ukukhiqiza Okungeziwe).
Njengoba ifomethi ye-AMR isekelwe kwifomethi yesitsha se-3GPP, i-3GA yinye isandiso sefayela le fomethi engayisebenzisa. Nakuba i-3GA isetshenziselwa ukulalelwayo, ungayidibanisi nefomethi yevidiyo ye- 3GP .
Ngaphezu kwalokho, futhi ukwenza konke kube okudideka kakhulu, amafayela we-AMR-WB aphela nge-AWB, afana kakhulu nokupela isipele kumafayela we-AWBR amafayela we-WriteOnline we-WordBar asetshenziswe nge-Clicker. Futhi, lezi zakhiwo ezimbili azihlangani ngalunye futhi azisebenzi nezicelo ezifanayo.
