AMR waa codka codec tuned in la diiwaan galiyo codka iyo wicitaanada telefoonka, taas oo ah sababta muusiga u maqli karaa xun oo ku jira.

AMR Su'aalaha Badiya La Weydiiyo Ee Ku Saabsan Beddelka
Waa maxay AMR file audio?
+
AMR waa codka ah ee narrow-band asal ahaan loo isticmaalo 2G / 3G networks mobile. AMR qabtaa codka la fahmi karo at bitrates aad u hooseeya oo waa caadi in dhoofinta fariimaha codka, rikoorrada push-to-talk, iyo xusuusta codka telefoonka feature hore. AMR samaysaa codka diiwaangelinta absurdly yar - saacad hadalka ku habboon in megabytes qaar ka mid ah - iyo waa waxa telefoonada badan weli diiwaanka wicitaanada in.
Immisa ayaa la waayo qaabka faylka AMR?
+
Wax kasta oo codsi-bixiyaha asalka ah uu go'aansaday inuu tirtiro, mana la soo celin karo. AMR wuxuu ku dhejiyaa iyadoo loo marayo qaabeynta waxa dhegta aysan ogeyn - codadka xasilloon ee ku fadhiya kuwa xoogga badan, frekansyada dhinacyada maqalka - iyo si joogto ah u tirtirto. Bitrate caafimaad leh oo aan la maqli karin in ka badan qof kasta. Waxa aan ahayn waa la soo celin karaa, sidaa darteed isbeddelka qaabka looma baahna inuu ilaaliyo xaaladda hadda jirta ee aan dib u soo celiyo asalka. AMR waa codsi codka narrowband socda u dhexeeya 4.75 iyo 12.2 kbps, qaabeynta wadnaha codka aadanaha ka badan sida ay u kala duwanaansho audio buuxa.
Maxaa keenay in AMR diiwaangelintayda ay u muuqato mid yar marka loo barbardhigo muusiga?
+
Maxaa yeelay ma aha mid loo yaqaan inuu qaado muusig. AMR waa codsi hadal ah oo loo yaqaan 'narrowband' oo loogu talagalay shabakada moobiilka, oo loo habeeyay in ereyga la fahmo laga bilaabo bitrate lagu cabiro kilobits hal-dhibcood ah. Wax kasta oo ka baxsan codka aadanaha ayaa la iska indho tiray waqtigii la qabtay. Marka loo beddelo qaabka heerka buuxa, diiwaangelinta ayaa laga isticmaali karaa meel kasta, laakiin ma awoodi karto inay ku darto frekwensiyada dib loo soo celiyey ee aan marnaba la soo bandhigin. AMR music burburin: 8 kHz bandwidth ka saaraa wax kasta oo kor ku xusan frekuency telefoonka, iyo wax lacag ah oo dib-codsiinta soo celin.
Meel bay faylasha AMR caadi ahaan ka yimaadaan?
+
Voicemail, raadiyo push-to-talk, telefoonada gacanta ee hore iyo diiwaanka telefoonka - meel kasta oo audio u baahan yahay in ay ku socdaan ka badan xagal cidhiidhi ah, qiimaha sare leh. Dhaqankaas waxa uu ka dhigayaa labadaba sababta faylasha waa yar yihiin iyo sababta ay u maqlaan sida ay sameeyaan. AMR waa Adaptive Multi-Rate, hadalka codec 3GPP standardized u GSM wicitaanada codka iyo mobile codka recorders.
Maxaa keenay in faylkayga AMR uu muujiyo magacyo aan la soo koobi karin ama sawirro?
+
Sababtoo ah qaabka si dhab ah waxba uma kaydin karaan. AMR waxaa lagu qeexay audio-ga, oo aan lahayn meel caadi ah oo loogu talagalay magaca, album ama sawirka qaboojinta, sidaas darteed ciyaartoyda waxay ku soo noqdaan inay muujiyaan magaca faylka. Isbedelka qaabka la calaamadeeyo waa waxa ka dhigaya maktabad la soo dejin karo - tags waa la qoray waqti lagu beddelayo oo aan la soo ceshan, sidaas darteed waxaad u baahan tahay inaad buuxiso wax kasta oo asalka aan waligood la qaadin.
Ma u baahanahay inaan weligey u kaydiyo faylasha cusub sida AMR?
+
Marka kaliya haddii wax ka hooseeya u baahan yahay. qaabka weli furaysaa, oo waxaa jira wax degdeg ah oo ku saabsan u beddelo faylka aan dhibaato sababi, laakiin waa in aan ka sii halkaas oo tooling ama waxtarka u socdaa. Wax kasta oo cusub, qaabka hadda ku baxa wax dheeraad ah oo ka hortagtaa wareegga soo socda ee su'aashan qaar ka mid ah sano ka dib hadda.
Maxaa ka dhigaya in AMR faylka uusan ku ciyaarin boggayaga?
+
Browsers decode a short, fixed list of audio formats and AMR is outside it, so the file downloads instead of playing or the player simply reports a error. Desktop software with a wider codec set opens it without trouble. Haddii audio ay tahay in lagu ciyaaro bogga webka, isbedelka waa xalka - qaabeynta ciyaaryahanka ma aha mid ku dari doona decoder browserka ma keeni doono.
Maxay tahay bitrate-ka aan u beddeli lahaa faylashayda AMR?
+
Xidhiidh goobta, ma aha asalka. Music, 256 ilaa 320 kbps waa mid cad in ay ku dhow dhagaystayaasha oo dhan; hadalka iyo podcasts, 96 ilaa 128 kbps waa tiro badan oo hal mar file mar kale. Codsiga kor ku qoran bitrate asalka ah meel la khasaariyey - waa runtii ilaalin audio oo horeyba u soo galay a lossy ka gudbaan oo waxba ka soo kabsan codsi ugu horeysay ee la tirtiro.
Ma AMR lossy ama lossless?
+
AMR waa lossy - encoder tirtirto xogta encoder xukuma in ay yihiin inaudible in ay gaaraan cabbirka file yar.
Maxaa aan u beddeli AMR in loo qaybiyo?
+
Email iyo qaybinta bulshada-media, AMR u badalo MP3 - playback guud iyo miisaanka file yar. Si aad u qaybiso sare-fidelity la audiophiles, u badalo FLAC ama WAV si ay u ilaaliyaan tayada asalka ah.
