MP3 kuya AAC Imibuzo Evame Ukubuzwa Yokuguqulwa

Yini oyenzayo i-MP3 kuya ku-AAC umguquli womsindo?

It re-encodes a MP3 audio file as AAC. Sample rate and channel count are preserved; the difference is the codec and container.

Ingabe isilinganiso sesampula kanye nesimo sesixhumi sigcinwa?

Ngephutha yebo — i-stereo ihlala i-stereo, isilinganiso sesampula sakuqala (44.1 kHz, 48 kHz, njll.) sithunyelwe ku-AAC output.

Ingabe MP3 kuya ku AAC ukuguqulwa kubuyiselwa emuva?

Ungaguqula i-AAC emuva ku-MP3 kule site. Uma ifomethi eyodwa ilahlekile, i-round-trip ayilungile noma ngabe ibukeka noma izwakala ifana.

Yini ikhwalithi yesipiliyoni okufanele ngilinde kusuka ku-MP3 kuya ku-AAC?

Izilungiselelo ezizenzakalelayo zidinga ukusakazwa / ukhwalithi ye-web — ngokubona kufana nomthombo weningi labasebenzisi. Ukusetshenziswa kwegobolondo, khetha ukhetho lwekhwalithi ephezulu kuzinhlelo zokushintsha.

Ingabe ukushintsha MP3 kuya ku AAC kuyingxenye yesithathu yokucindezela okulahlekile?

Yebo, futhi kufanelekile ukuhlela. Izifomethi zombili ziyi-lossy, ngakho-ke i AAC encoder isebenza kusuka kumsindo osele udlulele esinye isikhala se-psychoacoustic, futhi iziphakamiso zayo zihlanganisa isiqephu sokuqala. Ku-192 kbps noma ngaphezulu, imiphumela ihlala icacile kakhulu. Uma une master engalahlekelwa yilutho, ukukopisha i AAC kusuka lapho kunciphisa isikhala esimibili ngokuphelele. MP3 ilahlekelwa: imodeli ye psychoacoustic isusa iziqongo ezingezona ezivamile, ezivame ukuba ngu-128 kuya ku-320 kbps. I-AAC ilahlekelwa yizinto kodwa isebenza kahle kunayo i-MP3, futhi iphatha kuze kube yi-48 channels ngokusemthethweni ngaphezu kokuboshwa ku-stereo design.

Uma ama-diski akhona ethekwini, ukushintshana kabusha kufomethi engalahleki nokukopela kusuka lapho kunikeza imiphumela engcono kunanoma iyiphi i-conversion yefayela elikhona. MP3 yi MPEG-1 Audio Layer III, eqediwe ngo-1993, futhi ikhona ifomethi yomsindo ekwazi ukuconywa ngokugcwele.

Yini ezoba namafayela ami MP3 ngemuva kokuguqulwa?

Amafayela alayishiwe kanye ne-AAC outputs zisuswa ngokuzenzakalela ngemuva kwefasitela lokugcinwa okuncane. Asihlolanga, asihlukanisi, noma siqeqeshe amafayela womsebenzisi. Ama-download links aqondile angaphansi kwesikhathi esilinganiselwe futhi axhunywe kwinhlanganiso yakho.

MP3

Amafayela e-MP3 asebenzisa ukucindezela okulahlekile ukunciphisa usayizi wefayela ngenkathi kugcinwa ikhwalithi yomsindo eyamukelekayo kubalaleli abaningi.
