M4R Chosinthira

M4R compresses ndi modeling zimene nkhope sadzaona - chisoni maganizo ozungulira pansi olimba, ma frequencies pa malire a kumvetsera - ndi mwamsanga kuchotsa izo. Pa bitrate bwino kuti ndi inaudible kwa pafupifupi aliyense. zimene sizosatheka ndi reversible, kotero kusintha kuti lossless mtundu amateteza dziko latsopano kuposa kubwezeretsa oyambirira. Payload ndi AAC, conventionally capped pa 40 masekondi, amene ndi m'mimba mwake iOS adzavomereza.

Chifukwa iOS ikuyang'ana pa kontena yokhayo yomwe ili mu fayilo ya ma toni ndipo imasiya chilichonse, ngakhale kuti ndichofanana ndi mawu amkati. A M4R ndi mawu a AAC odziwika bwino ndi kuwonjezeka kosiyana ndi nthawi yopitilira pafupifupi masekondi asanu ndi awiri. Sinthani mndandanda, chotsani ku gawo lomwe mukufuna, ndikukopa kudzera pa Finder kapena pulogalamu ya Apple Devices. M4R ndi iPhone ringtone - a osiyana AAC wapamwamba mu MP4 chidebe ndi kuwonjezeka anasintha kuti iTunes amapereka izo monga tone.

Mawebusayiti amachotsa mawu osakira m'mndandanda wafupi wa mawu osakira ndipo M4R ndi kunja kwa mndandandawu, kotero fayilo imatsitsa popanda kusewera kapena wosewerayo amatumiza vuto. Mapulogalamu a desktop ndi ma codec osiyanasiyana amatsegula popanda vuto. Ngati mawu osakira amayenera kusewera patsamba la webu, kusinthidwa kwake ndi njira yoyenera - palibe kukonzekera kwa wosewerayo kuwonjezera mawu osakira omwe mawebusayiti satumiza. M4R ndi Apple-khama ndi m'lifupi zokwanira; chilichonse kuposa 40 masekondi ndi chisoni anakana ndi foni.

No. The mtundu anatuluka Apple ndi zimene zake zipangizo ndi mapulogalamu kupanga mwa default, koma mavidiyo okha ndi osiyana ndi kuphunzira bwino kumeneko ndi choyenera chida. Kusinthanitsa pano chimachitika pa seva, kotero palibe QuickTime kukhazikitsa, palibe Apple hardware ndi palibe platform-osiyana codec pakiti ndi kukhudzana kulikonse m'njira.

Kugwirizana ndi malo osankhidwa, si cholinga. Kwa nyimbo, 256 mpaka 320 kbps ndi zosaoneka kwa aliyense womvetsera; kwa mawu ndi podcasts, 96 mpaka 128 kbps ndi zambiri ndipo amadula fayilo ku theka. Kulemba mawu kudzera pa ma bitrate ochokera kumawononga malo - amasunga mawu omwe kale apita ku lossy pass ndipo sabwezeretsa chilichonse chomwe chimatulutsidwa ndi wolemba mawu woyamba.
