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. M4A ali AAC m'malamulo ambiri, kapena Apple Lossless (ALAC) pamene anachokera ku lossless rip.

Kodi woimba, album ndi kusindikiza kwa M4A yanga kumatha kusinthidwa?

Amachita komwe mtundu wofunikira uli ndi malo omwe angawaike. M4A amayendetsa ma tag ndi mapangidwe ophatikizidwa ngati gawo la fayilo, ndipo kusintha kwa ma copy a pamalo onse omwe amamvetsetsa. Ma targets opanda malire ndi osiyana - adafotokozedwa pambuyo poti kulemba kwa tag ndi koyenera ndipo samangokhala ndi chilichonse, choncho buku losinthidwa limakhala ngati mchenga wa nyimbo zopanda dzina.

Yes — format imagwira bwino ntchito ndi ma channels ambiri kuposa awiri, kotero kuti surround mix imasunga ma channels ake ophatikizidwa moyenera, osati kuikidwa mu stereo panjira. Kodi mumamva ngati surround kumadalira pa mbali ya mbali: wolandirayo adzachotsa ma channels onse, foni idzalowetsa panthawi yosewera popanda vuto lililonse. Kusintha kwa stereo-only format kumachititsa kuti kuikidwa kukhale kosalekeza.

Kodi M4A idzasewera mobwerezabwereza patsamba la webusaiti?

Ndikukhulupirira. M4A 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 format iyi nthawi zambiri ndi njira yofupikitsa kuti ikhale yosewera patsamba.

Kusinthanitsa pano chimachitika pa seva, kotero palibe QuickTime kukhazikitsa, palibe Apple hardware ndi palibe platform-osiyana codec pakiti ndi kukhudzana kulikonse m'njira.

Kodi ndiyenera kusintha bwanji mafayilo anga a M4A?

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.

Kodi kugwiritsa ntchito M4A kumafunikira chilolezo cha patent?

Sichoncho ngati simukupempha kuti ichite zimenezi. Kusintha kumasunga mitengo ya machitidwe a m'mawu - 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 izo. Kulephera kwachidziwitso ndi chowonadi: 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.

Free conversions kuyendetsa imodzi wapamwamba pa nthawi (kuphatikiza zida zimatenga awiri); a ndalama malire ndi zimene zimatsegula processing gulu ndi zikuluzikulu per-fayilo malire, amene ndi zimene amachititsa kusintha archive lonse zothandiza.
