AAC Zida

AAC 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. AAC ndi lossy koma bwino kuposa MP3, ndipo amagwira mpaka 48 ma channels mwachilengedwe kuposa kukhala bolted pa stereo kupanga.

Chifukwa foni encodes ndi chip kuposa processor, ndipo izi ndi mtundu kuti silicon amagwiritsa ntchito. Voice memos, video soundtracks ndi kutumiza mavidiyo onse akubwera kuchokera pamodzi encoder, amene ndi chifukwa chake iwo kugawana mtundu kuti ali ndi chilichonse chokhudzana ndi zimene inu munali kujambula. It plays on Apple hardware without a thought and needs converting rather more often everywhere else.

Amachita komwe mtundu wofunikira uli ndi malo omwe angawaike. AAC amayendetsa ma tag ndi mapangidwe ophatikizidwa ngati gawo la fayilo, ndipo kusintha kwa ma copy a ma copy a ma copy a ma copy a ma copy a ma copy a ma copy a ma copy a ma copy a ma copy a ma copy a ma copy a ma copy a ma copy a ma copy a ma copy a ma copy a ma copy a ma copy a ma copy a ma copy a ma copy a ma copy a ma copy a ma copy a ma copy a ma copy a ma copy a ma copy a ma copy a ma copy a ma copy a ma copy a ma copy a ma copy a ma copy a ma copy a ma copy a ma copy a ma copy a ma copy a ma copy a ma copy a ma copy a ma copy a ma copy a ma copy a ma copy a ma copy a ma copy a ma copy a ma copy a ma copy a ma copy a ma copy a ma copy a ma copy a ma copy a ma copy a ma copy a ma copy a ma copy a ma copy a ma copy a ma copy a ma copy a ma copy a ma copy a ma copy a ma copy a ma copy a ma copy a ma copy a ma copy a ma copy a ma copy a ma copy a ma copy a ma copy a ma copy a ma copy a ma copy a ma copy a ma copy a ma copy a ma copy a ma copy a ma copy a ma copy a ma copy a ma copy a ma copy a ma copy a ma copy a ma copy a ma copy a ma copy a ma copy a ma copy a ma copy a ma copy a ma copy a ma copy a ma copy a ma copy a ma copy a ma copy a ma copy a ma copy a ma copy a ma copy a ma copy a ma copy a ma copy a ma copy a ma copy a ma copy a ma copy a ma copy a ma copy a ma copy a ma copy a ma copy a ma copy a ma copy a ma copy a ma copy a ma copy a ma copy a ma copy a ma copy a ma copy a ma copy a ma copy a ma copy a ma copy a ma copy a ma copy a ma copy a ma copy a ma copy a ma copy a ma copy a ma copy a ma copy a ma copy a ma copy a ma copy a ma copy a ma copy a ma copy a ma copy a ma copy a ma copy a ma copy a ma copy a ma copy a ma copy a ma copy

Yes — format imagwira bwino ntchito ndi ma channels ambiri kuposa awiri, choncho surround mix imasunga ma channels ake ophatikizidwa m’njira yoyenera, osati kuikidwa mu stereo. Kodi mudzawamvetsera ngati surround kumadalira pa mbali ya mbali: wolandirayo adzawachotsa ma channels onse, foni idzawaphatikizira m’nthawi yosewerayo, ngakhale. Kusintha kwa stereo format imachititsa kuti ma channels azikhala ophatikizidwa mwamsanga.

Ndikukhulupirira. AAC ndi imodzi mwamaudindo a audio omwe amagwiritsa ntchito masamba, motero amatha kutulutsidwa m'mawu a audio kapena wosewera podcast ndipo amagwira ntchito zonse popanda plugin kapena fayilo ya fallback. Izi zimapangitsa kuti zikhale zotetezeka zofalitsa, ndipo chifukwa chake kusinthira kujambula kwa exotic ku mtunduwu ndi nthawi zambiri njira yofupikitsa kuti ikhale yosewera patsamba. AAC akuoneka bwinobwino kuposa MP3 pansi 128 kbps ndi default audio track mu MP4, YouTube, Apple Music ndi kufalitsa.

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 fayiloyo ku theka. Kulemba mawu kudzera pa ma bitrate ochokera kumawononga malo - amasunga mawu omwe kale apita kudzera pa lossy pass ndipo sabwezeretsa chilichonse chomwe chimatulutsidwa ndi wolemba mawu woyamba.

Sichoncho ngati simukupempha kuti ichite zimenezi. Kusintha kumasunga mitengo ya machitidwe a m'mawu ochokera - 48 kHz imakhala 48 kHz, 44.1 kHz imakhala 44.1 kHz - chifukwa kubwezeretsa machitidwe a m'machitidwe ndi mtengo wotsika wabwino wopanda phindu pamene palibe chomwe chimafuna kuti. Zosagwirizana ndi izi ndi zachidziwikire: ma CD a nyimbo amafuna 44.1 kHz, ena mwa osewera a hardware oyambirira amavomereza chilichonse chokhudzana ndi izi, ndipo ma pipelines a mawu nthawi zambiri amafuna 16 kHz. Sankhani mitengo yokhayokha m'machitidwe amenewa ndipo musiya izi zipite.

Kwambiri nthawi zonse, ndipo ndi bwino kumvetsa chifukwa chake: kuwonjezeka ndi label, pamene bytes m'maganizo ndi zopangidwa kwa mtundu wina mfundo. Kusintha dzina amapanga fayilo amene dzina lake amalonjeza chinachake za zinthu zake sikuti kubweretsa, ndi zimene amatsegula izo kapena amakana fayilo kapena misreads izo. Mmodzi waukulu kulephera ndi awiri mtundu amene ndi weniweni wofanana wonyamula pansi pa dzina losiyana - ndi ngakhale pamenepo bwino rewrap ndi chitetezo kuposa kusintha dzina.

Ndi akaunti, yeah - kugwa iwo limodzi ndipo iwo ali mu mnda monga ntchito imodzi kuposa kusamalira mmodzi pa nthawi, ndi zosankha zofanana zogwiritsira ntchito m'magulu ndi zotsatira zobwerera limodzi. Free conversions kuyendetsa imodzi wapamwamba pa nthawi (kuphatikiza zida zimatenga awiri); ndalama plan ndi zimene zimatsegula processing gulu ndi zikuluzikulu per-fayilo malire, amene ndi zimene amachititsa kusintha archive lonse zothandiza.

Idzathetsedwa. Kutsitsa ndi zotsatira zosinthidwa zimasungidwa pa seva nthawi yomwe ntchitoyi imafunikira ndipo zimathetsedwa mwamsanga; kutumiza kumachitika pa HTTPS m'njira ziwirizi. Palibe amene amawerenga zomwe zilimo, palibe chomwe chimaphatikizidwa mu index, ndipo palibe chomwe chimapita kwa wina aliyense. Ngati simukufuna kuyembekezera kuchotsa kwachidule, kutseka ntchitoyo kumachotsa mafayilo mwamsanga.
