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

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.

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 mtunduwu ndi nthawi zambiri njira yofupikitsa kuti ikhale yosewera patsamba. M4A amasunga rich iTunes-style metadata, zigawo ndi ntchito zojambulajambula osatha, ndi ndi native audio mtundu pa onse Apple chipangizo.
Kodi ndimafunikira Mac kuti ndichite ntchito ndi M4A mafayilo?

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.
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?
