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 dib u soo celiyo asalka.

A M4R waa caadi AAC audio la extension kala duwan iyo muddo ka hooseysa afartan ilbiriqsi. Beddelka track, ka jarto qaybta aad dhab ahaan u baahan tahay, iyo nuqul ka mid ah Finder ama Apple qalabka app. M4R waa iPhone ringtone - a caadi ah AAC file in MP4 container la kordhinta la beddelay si iTunes files sida codka.
Maxaa ka dhigaya in M4R faylka uusan ku ciyaarin boggayaga?
+
Browsers decode a short, fixed list of audio formats and M4R 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. M4R waa Apple-keliya iyo dhererka-la xaddiday; wax kasta oo ka badan 40 ilbiriqsi waa si qaylo leh loo diiday telefoonka.

+
No. format ka soo baxay Apple iyo waxa ay qalabka iyo software soo saaraan default, laakiin files iyaga oo keliya waa caadi iyo akhrin fiican meel kale oo la qalab saxda ah. U beddelo halkan ka dhaca server, sidaas darteed ma QuickTime install, ma Apple hardware iyo ma platform-ka gaar ah codec pack waxaa ka mid ah meel kasta oo ka mid ah habka.
Maxay tahay bitrate-ka aan u beddeli lahaa faylashayda M4R?

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 M4R 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 beddeli kartaa ku saabsan ku beddelo file aad hore u leedahay.
Ma soo beddelidda ma beddeli kartaa heerka tusaale ee M4R 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 M4R?
+
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 magacabo.
Maxaa ku dhaca faylka M4R ka dib markii la beddelay?
+
Waxaa la tirtiri doonaa si otomaatig ah. Upload iyo natiijada la beddelay ku nagaan servers our in ka badan 24 saacadood, taas oo ka tagay waqti si ay u soo dejisan natiijada, oo markaas waxaa laga saaray by nadiifinta otomaatiga ah.

+
Files yaryar si wax ku ool ah u instant, iyo xaaladaha in ay qaataan waqti dhab ah waa kuwa sameeya shaqada dhabta ah: diiwaan dheer oo uu leeyahay in la soo celiyo-coded frame by frame, a warqad scanned socda ka mid ah aqoonsiga calaamad, ama qayb aad u weyn. Haddii ay isbedelka kaliya rewraps ama repackages xogta hadda jira uu ku sii socdaan si deg deg ah, xitaa haddii ay tahay sida weyn ee file ah, sababtoo ah waxba ma aha in la decoded.
