M4R Isiguquli

Tshintsha M4R kuya 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

Ingabe i-M4R ilahlekelwa noma ayilahlekelwanga?

M4R ilahlekelwa — umbhalo-mbhalo ususa idatha umbhalo-mbhalo ucabanga ukuthi ayikwazi ukulinganiswa ukuze ifike kubungakanani befayela elincane. I-M4R iphuma ngokuqondile ku-iOS Sounds list nge-Finder noma i-iTunes ngaphandle kokusebenzisa okuningi.

Ingabe ubuhle bulahlekile kuhele M4R?

Noma yini oyenzayo umbhalo-mbhalo oqale uthathe isigqibo sokuyisusa, futhi ayikwazi ukubuyiselwa. M4R icindezela ngokumodela lokho okungeke kuphawulwe yindlebe - imisindo ehlanzekile ehlala ngaphansi kwezikhulu, iziqongo ezisezindaweni zokulalela - futhi isuse ngokuqhubekayo. Ku-bitrate ephephile engeke ikwazi ukulizwa yinoma ngubani. Okungaba khona kungahle kubuyiselwe emuva, ngakho ukushintshana kufomethi engalahleki igcina isimo samanje ngaphezu kokubuyisela okuqale. 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 ukufaka kungxenyekazi oyifunayo, futhi uyikope nge-Finder noma i-Apple Idivayisi ye-app. M4R yi-iPhone ringtone — ifayela elijwayelekile le-AAC ebhokisini le-MP4 nesiqephu esishintshiwe ukuze i-iTunes ifile njenge-tone.

Kungani ihele M4R alidlalwa kumsakazo wami?

Amabhuleki aqokomisa uhlu oluncane, oluqinile lwefomethi yomsindo futhi M4R lungaphandle 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 umqokomisi oqokomisa umsindo umbhukeli awuthumeli. M4R i-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 ibekwe 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 ngalezi zinkinga bese ushiya icala linye.

Yini okufanele ngiguqule M4R ukuze ngiyihlukanise?

Ukudlulisa i-imeyili kanye nokudlulisa imidiya yomphakathi, guqula i-M4R ibe yi-MP3 — ukudlulisa okuphelele nobukhulu befayela elincane. Ukudlulisa okuphezulu-kuthembekile nabangani besandi, guqula ube yi-FLAC noma i-WAV ukuze ugcine ukhwalithi yokuqala.

Ingabe ukuguquka kuzoshintsha ubukhulu behele?

Ukushintsha i-M4R ibe yifomethi engalahleki njenge-WAV noma i-FLAC igcina ubukhulu bukhulu; ukushintsha ibe yi-MP3 noma i-AAC nge-bitrates ejwayelekile (192-320 kbps) icindezela ihele ngama-5-10x ngeshintsho elincane lomgangatho okwazi ukuwubona.
