M4A ukuba AAC Imibuzo Ebuzwa Rhoqo Ngokuguqula

Ndiyiguqula njani i-M4A yesandi ibe yi-AAC ngaphandle kokulahlekelwa umgangatho?

Layisha phezulu ifayile ye M4A kwaye umguquli wethu ukhetha i AAC codec / uthelekiso lwe-bitrate oluhambelana nomcebo. Isiphelo esingalahliweyo (AAC = WAV / FLAC / ALAC) sigcina isampuli nganye; isiphelo esingalahliweyo (AAC = MP3 / AAC / OGG) simiselwe kwi 192 kbps ebonisa ngaphaya kweendlebe ezininzi.

I-AAC isebenzisa i-bitrate enjani?

Okumiselweyo 192 kbps ye-lossy AAC; idlula-kwi-lossless AAC. Buyisela ngaphezulu kwi-320 kbps ye-audiophile okanye kwi-96 kbps yelizwi/podcast. Ukhetho lutshintshiselana ngobungakanani befayili ngokuchasene nobuxoki obunokulungiswa kwi-bitrates ephantsi kakhulu.

Ingaba ukutshintsha ukusuka kwi-M4A ukuya kwi-AAC kuya kunyusa ubunjani besandi sam?

Ukuba i-M4A ilahlekile kwaye i-AAC ayilahleki (umzekelo, MP3 → WAV), i-AAC ifayile ayingcono kune-M4A — awunakubuyisela ulwazi olusele luthunyelwe. Ukuba i-M4A ayilahleki kwaye i-AAC ilahlekile, lindele ukuba i-AAC codec iphinde icinezele; kwi-192 kbps oku kucacile kuninzi lwezinto eziquletheyo.

Ingaba i-AAC iya kugcina inqanaba lesiseko elifanayo njenge-M4A?

Ngokungagqibekanga ewe (48 kHz M4A → 48 kHz AAC). Ukuba ufuna ukunyusa isampulu ukuhambelana (umzekelo. 96 kHz → 44.1 kHz yokushicilela i-CD) ukhetho lwesampulu-yexabiso eliphambili yenza oku ngesampulu ephezulu yomgangatho.

Ndingazilungisa njani ilizwi kwinyathelo M4A ukuya kwiAAC?

Ewe — iifayile ezilayishwe phezulu ze-M4A ziqhubekekiswa kubasebenzi abakhethekileyo kwaye zicinywe kwimizuzu. Asiyi kudlala, sigcine, okanye sisebenzise okuqulethwe sisithethi.

Ithatha ixesha elingakanani ukutshintsha i-M4A yeyure enye ibe yiAAC?

I-codec efanayo yoku-multiplex: 10-30 imizuzwana. Yenza kwakhona i-encoding kwi-codec eyahlukileyo: ngokuqhelekileyo 10-20% yobude bomthombo, ngoko ke i-M4A → AAC yeyure enye igqiba kwimizuzu engama-6-12.
