M4R Isiguquli

Guqula M4R ukuya futhi kusuka kumafomethi ahlukahlukene

Mayelana M4R

M4R yi M4A ebizwa kabusha nge-iPhone ringtones, ngakho-ke ubude obulinganiselwe busebenza endaweni yobude obusezingeni eliphakeme.

M4R Imibuzo Evame Ukubuzwa Yokuguqulwa

Yini ihele M4R?

M4R is an iPhone ringtone file format based on AAC audio encoding.

Ingabe ubuhle bulahlekile kuhele M4R?

Noma yini encoder yakuqala ekhetha ukuyisusa, futhi ayikwazi ukubuyiselwa. M4R icindezela ngokumodela lokho okungekuqaphela indlebe - imisindo ekhululekile ehlala ngaphansi kwezikhulu, iziqongo eziphezulu zokulalela - futhi isuse ngokuqhubekayo. Ku-bitrate ephephile engeke ikwazi ukulalela wonke umuntu. Okunye okungaba khona kubuyiselwa emuva, ngakho ukushintshana kufomethi engalahlekelwa yisimo samanje ngaphandle kokubuyisela okungaphambili. I-payload yi-AAC, ejwayelekile ifinyelela kumasekhondi angama-40, okungukuthi umsindo ophakathi nendawo iOS uzowuvuma.

Kungani umsindo wocingo we-iPhone kufanele ube M4R?

Ngenxa yokuthi i-iOS ibheka umgqomo othile kwifolda yamathoni futhi ishiya ngaphandle noma yini, noma kunjalo umsindo ngaphakathi ungafana. A M4R yi-AAC umsindo ojwayelekile onesibanzi esihlukile kanye nokuphila ngaphansi kwamasekondi angama-40. Gcina umculo, ugweme kungxenyekazi oyifunayo, futhi ukope ngokuya nge-Finder noma i-Apple Izinhlelo ze-app. M4R yi-iPhone ringtone — ifayela elijwayelekile le-AAC ebhokisini le-MP4 nesibonisi esishintshiwe ukuze i-iTunes ifile njenge-tone.

Ingabe M4R isetshenziswa ngento enye ngaphandle kwezingcingo?

Kunzima, futhi lokhu kusekelwe ku-design hhayi ku-limitation — umsindo ngaphakathi usuka ku-stream ejwayelekile ecindezelwe, futhi ubanzi bukhombisa ukuthi uyini umphumela wayo ku-phone. Noma yini edlalayo idlala njenge-audio ejwayelekile, esebenza kahle. Ukushintshana nganoma yisiphi isiqondiso kubizwa ngokuthi ukushintsha igama kanye nokusika ubude ngaphezu kokuphinde ubhale kabusha.

Ingabe umculi, i-album nesithombe sokuzivikela ku M4R yami sizohlala siguqulwa?

Bakwenza lapho ifomu eligunyaziwe linesizinda sokubeka. M4R lithwala izithonjana nemisebenzi yezandla efakwe njengengxenye yefayela, futhi ukuguqulwa kwenza amakhophi ngaphesheya kwendawo elingaqondakalayo. Izithonjana ezingacindezelwanga ziyisinqumo - zicacisiwe ngaphambi kokuphawula kwakuyithemba elijwayelekile futhi zigcina cishe akukho, ngakho ithala eliguqulwe ngalo ndlela lifika njengedonga lemisindo engabizwanga.

Kungani ihele M4R alidlalwa kumsakazo wami?

Amabhuleki aqopha uhlu oluncane, oluqinile lwefomethi yomsindo futhi M4R ungaphandle kwalo, ngakho ihele likhuphuka endaweni yokudlala noma umdlali ukhombisa iphutha. Isofthiwe yedesktop enesethingi se-codec esibanzi ivula ngaphandle kwezinkinga. Uma umsindo udlala kukhasi le-web, ukushintsha kuyinto elungile — akukho ukumiswa komdlali kuzongeza umbhalo oqoshiwe umbhukeli awuthumeli. M4R yi-Apple kuphela futhi ilinganiselwe ubude; noma yini engaphezu kwamasekondi angama-40 iphoqelwe ukulahleka yifoni.

Ingabe ngidinga iMac ukusebenza namafayela M4R?

Akuna. Ifomethi yavela Apple futhi yilokho izinhlelo zayo nesoftware kukhiqiza ngokuzenzakalela, kodwa amafayela ngokwawo zivamile futhi ukufunda kahle elsewhere ngethuluzi elifanele. Ukushintsha lapha kwenzeka kuseva, ngakho akukho QuickTime ukufakela, akukho Apple hardware futhi akukho platform-specific codec pack ihlobene nanoma kuphi kwinqubo.

Yini i-bitrate okufanele ngiyiguqule amafayela ami M4R?

Uhlu lwendawo esiya kuyo, hhayi umsuka. Ukudlalwa kwengoma, 256 kuya ku-320 kbps kucacile kuwo wonke umuntu olalelayo; ukukhuluma nokulalela ipodcasts, 96 kuya ku-128 kbps kuningi futhi kushiya ihele ngaphesheya. Ukungenisa umsindo ngaphezu komsuka we-bitrate kulahlekile isikhala — kugcina umsindo osele udlulele nge-lossy pass futhi akubuyiseli lutho umngenisi wokuqala olahlekile.

Ingabe ukusebenzisa M4R kuthatha ilayisense lepatenti?

Akunakho okukudingayo. Ama-codecs ahlobene ahlobene ne-patent pools, futhi ilayisense libekwe ngabantu abathumela ama-decoders — ifoni, i-browser, i-operating system — isikhathi eside ngaphambi kokuba ihele lifike kuwe. Lokhu kusho ukuthi ifomu likhona kuwo wonke amahardware futhi kungani ama-royalty-free alternatives akhona, futhi ashintshanga noma yini mayelana nokushintsha ifayela oline.

Ingabe ukushintshana kushintsha isilinganiso sesampula se M4R yami yomsindo?

Akunakwenzeka ngaphandle kokuthi ucela. Ukuguquka kugcina umsuka wezinga — 48 kHz uhlala 48 kHz, 44.1 kHz uhlala 44.1 kHz — ngoba ukusatshalaliswa kabusha kubiza kakhulu futhi akusebenzi uma akukho okudingayo. Iziphuzo zikhona: ama-CD omsindo adinga u-44.1 kHz, abanye abadlali behardware abadala bamukela okuthile, futhi amapayipi omsindo avame ukudinga u-16 kHz. Misela izinga ngokucacile kulezi zinkinga bese ushiya icala linye.

Ingabe ngingenza ngiphinde ngibize isiqephu endaweni yokushintsha M4R?

Kunzima kakhulu, futhi kufanelekile ukuqonda ukuthi kungani: isithonjana siyisihloko, ngenkathi ama-bytes ngaphakathi kufakwe ngefomethi eyodwa ekhethekile. Ukushintsha igama kwenza ihele igama lakhe lithembisa okuthile okuqukethwe kwayo akusho ukunikela, futhi noma yini evula ihele noma liyiphoqa noma liyifunda kabi. Ukuphela kwephutha elincane yifomethi ezimbili ezikhona ngokusemthethweni ibhokisi elifanayo ngaphansi kwezinhlamvu ezahlukene — futhi ngisho lapho ukuphinda uphinde
