WebM ukuba M4A Imibuzo Ebuzwa Rhoqo Ngokuguqula

Ndiyikhupha njani kuphela i-audio track ukusuka kwi WebM njenge M4A?

Layisha phezulu ifayili WebM kwaye umguquli ukhupha umsinga wesandi ukusuka kwisiqulathi seefayili WebM, emva koko uguqula ikhowudi ibe yi M4A. Ii-frames zevidiyo zilahliwe — akukho xesha lesibini lokudlulisa ividiyo, akukho lahlekelwa komgangatho ngaphezulu kwento ekhoyo kwi-M4A codec. I-WebM yinxalenye encinci eqinileyo ye-Matroska epapashwe yiGoogle ngo-2010 ekhethekileyo ukunika i-HTML5 ividiyo isiqulathi seefayili esingenazo iirhafu. I-M4A yi-MP4 equlethe i-audio kuphela, kwaye yiyo into eyenza i-iTunes, i-Apple Music kunye ne-iPhone Voice Memos app.

Ingaba ukutshintsha WebM ukuya ku M4A kujikelezo lwesibini lokucinezela okulahlekileyo?

Kwi 192 kbps okanye ngaphezulu isiphumo sihlala sicacile kubaninzi bokuziva. Ukuba une master engalahleki naphi na, ukukopela i M4A ukusuka apho endaweni yoko ikhusela i pass kabini ngokupheleleyo.

I-M4A emiselweyo ye-bitrate yi-192 kbps (ibonisa ngaphaya kwengoma kwiimvakalelo ezininzi). Nciphisa kwi-320 kbps yemveliso yeaudiophile, okanye 96-128 kbps yelizwi/ipodcast apho ifayili encinci iphambili. Iinjongo ezingalahlekiyo M4A (WAV, FLAC) zingahoyi isicwangciso se-bitrate kwaye zigcine zonke iiseti.

Ingaba ukutshintsha ukusuka ku WebM ukuya ku M4A kuya kunyusa ubunjani besandi sam?
