WMA Su'aalaha Badiya La Weydiiyo Ee Ku Saabsan Beddelka
Maxaa ah WMA fayl?
+
WMA (Windows Media Audio) is an audio format developed by Microsoft.
Immisa ayaa la yaab leh in la waayo faylka WMA?
+
Wax kasta oo codsi-bixiyaha asalka ah uu go'aansaday inuu tirtiro, mana la soo celin karo. WMA wuxuu ku dhejiyaa iyadoo loo marayo qaabeynta waxa dhegta aysan ogeyn - codadka xasilloon ee ku fadhiya kuwa xoogga badan, frekansyada xagasha 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 karo, sidaa darteed isbeddelka qaabka looma baahna inuu ilaaliyo xaaladda hadda jirta ee aan ahayn soo celinta asalka. WMA waa lossy default, in ASF container, la lossless iyo codka-optimised noocyada in aad u yar oo la kulmi.
Maxaa ka dhigaya CD rippers default in WMA?
+
Waayo, waxaa ahaa qaabka oo sameeyey music ururinta ku habboon dadka hardware dhab ahaantii lahaa, iyo defaults waa isku dhafan muddo dheer ka dib markii xaddidaadda waa tegay. A ripped Library waa sidaas darteed caadi ahaan heshiiska la doortay sano ka hor in ka badan go'aan ku saabsan muusiga. Re-ripping ka diskiga siin master wanaagsan; u beddelo waxa aad hore u leedahay ma karaan, sababtoo ah faahfaahinta ka hor inta aan la qaadin waa in aan la file in la soo celiyo. WMA waa Windows Media Audio, jawaabta Microsoft ee MP3, la bilaabay 1999 iyo la isku darsaday oo dhan Windows aasaaska ee xilligaas.
Ma artist, album iyo cover art on WMA ii badbaadin doonaa conversion?
+
Waxay sameeyaan halka qaabka la doonayo uu leeyahay meel ay ku dhigaan. WMA waxay ku qaadataa astaamaha iyo farshaxanka la aasaasay sida qayb ka mid ah faylka, iyo nuqul ka mid ah nuqul ka mid ah dhammaan goobaha meesha ay tahay in la fahmo. Targets-ka aan la isku dhejin ayaa ah xaddidaad - waxay la soo bandhigay ka hor inta aan la soo bandhigin waxay ahayd rajada caadiga ah oo waxba kama haysan, sidaa darteed maktabad la beddelay ayaa sidaa u yimaada sida derbi raadadka aan la magacaabin.
Ma u baahanahay inaan weligey u kaydiyo faylasha cusub sida WMA?
+
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 socdaan. Wax kasta oo cusub, qaabka hadda ku kacaya wax dheeraad ah oo ka hortagtaa wareegga soo socda ee su'aashan qaar ka mid ah sano ka dib hadda. WMA waa aan la taageerin in ka badan meel kasta oo ka baxsan Windows, iyo files WMA hore u qaadi karaan DRM in ay xaddidaan isbedelka oo dhan.
Ma file WMA ma qaadi karaa 5.1 isku darka surround?
+
Haa - qaabka xakamayn karaa in ka badan laba kanaal si sax ah, sidaas daraaddeed isku darka surround haystaa qaabkeeda channel ka badan in la isku dhajiyay in stereo on the way in. Haddii aad maqasho sida surround ku xiran yahay dhamaadka fog: a receiver codsiga codsiga channels oo dhan, telefoonka downmix doonaa waqti playback kastoo.
Maxaa ka dhigaya in WMA faylka uusan ku ciyaarin boggayaga?
+
Browsers decode a short, fixed list of audio formats and WMA 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 uu ku ciyaaro bogga webka, isbedelka waa xalka - ciyaaryahanka konfiguration ma sii kordhin doono decoder browserka ma keeni doono.
Maxaa WMA kaliya u shaqeeyaa si sax ah Windows?
+
Sababtoo ah baakadka waa badhka fudud. WMA waxaa lagu qeexay koodka Microsoft-ka, iyo wax ka badan waxba oo ka baxsan Windows-ka ma aha in lagu soo bandhigo decoder kuwaas - sidaas darteed faylka ayaa la furaa, wuxuu ku wargeliyaa muddada, ka dibna wuxuu soo saaraa sawir ama cod aan jirin. Ku rakibidda codec pack waa jawaabta hore iyo mid daciif ah; ku beddelidda payload in wax kasta oo platform kasta oo horeyba loo decoded waa midka adkaysta.
Maxay tahay bitrate-ka aan u beddeli lahaa faylashayda WMA?
+
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 isticmaalka WMA ma u baahan yahay ruqsad patent ah?
+
Ma aha adiga. codecs ka qayb qaataan waxaa ka mid ah badeecada patent pools, iyo liisanku waa la go'aamiyey by dadka decoders doonta - telefoonka, browser, nidaamka hawlgalka - muddo ka hor file gaadho aad. Waa sababta qaabka waa meel kasta oo hardware iyo sababta royalty-free doorasho ka jira oo dhan, iyo waxba kama beddelo ku saabsan ku beddelo file aad hore u leedahay.
Ma soo beddelidda ma beddeli kartaa heerka tusaale ee WMA audio?
+
A isbedelka haystaa qiimaha asalka ah - 48 kHz sii joogaa 48 kHz, 44.1 kHz sii joogaa 44.1 kHz - sababtoo ah resampling waa qiimaha tayada yar ee faa'iido la'aan marka waxba ma u baahan yahay. Isku-dhafka waa run: CD-yada audio u baahan yihiin 44.1 kHz, qaar ka mid ah ciyaartoyda hardware hore u aqbalaan wax kale, iyo codka pipelines badanaa doonayaan 16 kHz. Set qiimaha si cad oo ku saabsan xaaladahaas oo iska sii daaya oo keliya kale.
Ma waxaan u bedeli karaa magacyada dheeriga ah ee aan u beddelo WMA?
+
In ka badan marnaba, iyo waa in la fahmo sababta: kordhinta waa mid label, halka bayt gudaha waxaa loo dhisay qaab gaar ah. Rename soo saaro file oo magaciisa ballan wax ay ku jiraan ma bixiyaan, iyo waxa ay u furan tahay ama diido file ama misreads. Isku-darka mid ka mid ah oo cidhiidhi ah waa laba qaabab oo dhab ahaanba waa midba midka kale ee baakadaha magacyada kala duwan - iyo xitaa ka dibna dib u soo celinta saxda ah waa ka ammaan badan yahay in la bedelo magac.
