AAC ukuba MP3 Imibuzo Ebuzwa Rhoqo Ngokuguqula

Ndiyiguqula njani i-AAC yesandi ibe yi-MP3 ngaphandle kokulahleka komgangatho?

Layisha phezulu ifayili AAC kwaye umguquli wethu ukhetha MP3 i-codec / uthelekiso lwe-bitrate oluhambelana nomcebo. Isiphelo esingalahliweyo (MP3 = WAV / FLAC / ALAC) sigcina yonke isampuli; isiphelo esilahliweyo (MP3 = MP3 / AAC / OGG) simiselwe kwi-192 kbps ebonisa iincwadi zelizwi ezithethayo kunye nemidlalo emininzi.

Ingaba ukutshintsha AAC ukuya ku MP3 kujikelezo lwesibini lokucinezela okulahlekileyo?

Ewe, kwaye kufanelekile ukucwangcisa. Zonke iifomati zilahlekile, ngoko ke i MP3 encoder isebenza kwisandi esisele sidlula kwindlela enye ye psychoacoustic, kwaye izigqibo zayo zidibanisa iseti yokuqala. Kwi 192 kbps okanye ngaphezulu isiphumo sihlala sicacile kubaninzi bokuziva. Ukuba une master engalahleki naphi na, ukukopela i MP3 ukusuka apho endaweni yoko ikhusela i pass kabini ngokupheleleyo. I-AAC ilahlekile kodwa isebenza kakuhle kune-MP3, kwaye iphatha ukuya kuthi ga kwi-48 yeendlela eziqhelekileyo kunokuba iboniswe kwi-stereo design. I-MP3 ilahlekile: imodeli ye-psychoacoustic isusa ukuphindaphinda indlebe ayikwazi ukuqaphela, ihlala kwi-128 ukuya kwi-320 kbps.

Ithini into ebangela ukuba i-multichannel yesandi iguqulwe kwi AAC ukuya kwi MP3?

Ijika ezantsi kwi-stereo, kuba MP3 ayinayo indlela esebenzayo ye-multichannel. Ukudibanisa ezantsi kusetyenziswa izilinganisi eziqhelekileyo ukuze unxibelelwano lwe-center-channel luhlale lucacileyo kwaye izijikelezi-ndawo zidityanisiwe kwinqanaba eliphantsi. Nantoni na exhomekeke kukubeka isiqhagamshelanisi esikhethekileyo iphela xa oku kwenzeka. MP3 igqityiwe nge AAC ne Opus kwinqanaba ngalinye le-bitrate, ayikwazi ukugcina ngaphezulu kweendawo ezimbini eziluncedo, kwaye ihlala idibanisa ulibaziso oluncinci lwe-encoder.

I-MP3 ifayili isebenzisa i-bitrate enjani?

Okumiselweyo yi-192 kbps ye-lossy MP3; igqityiwe-kwi-lossless MP3. Nciphisa kwi-320 kbps ye-audiophile okanye 64-96 kbps ye-audiobooks yegama elithethayo (elibonisa ngaphaya lelizwi, liphelisa ubungakanani befayili).

Ingaba ukutshintsha ukusuka ku AAC ukuya ku MP3 kuya kunyusa ubunjani besandi sam?

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

Ingaba i-AAC ukuya kwi-MP3 igcina i-ID3 / i-metadata tags?

Ewe — isihloko, umculi, i-albham, unyaka, inani lengoma, ubugcisa be-albham, kunye nabaphawuli besiqendu (ababalulekileyo kwiincwadi zesandi) bafundwa ukusuka kwi AAC kwaye babhalwe kwi MP3 isiqulathi seefayili apho i-MP3 ifomati ixhasa ii-tags. Ukwakhiwa kwencwadi yesandi ye-M4B ijikeleza-jikeleza kwi-M4B ne-AAX → i-M4B i-output.

Ndingaguqula izigidi zeefayili AAC zibe MP3?

Ewe - susa isiqulathi seefayili se AAC ngaphakathi kwaye siza kuziqhubekekisa ngokuthe tye. I-Premium inemisebenzi ethe tye eninzi kwaye akukho bukhulu befayili nganye obuphezulu, ngoko ke i-500-file batch igqiba kwimizuzu kunokuba iphele kwimizuzu emininzi.

Ingaba i-MP3 iya kugcina inqanaba lesampuli elifanayo njenge-AAC?

Ngokungagqibekanga ewe (48 kHz AAC → 48 kHz MP3). 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 AAC ukuya kwi MP3?

Ewe - ukhetho lokwenza lusebenze ngokuqhelekileyo lusebenzisa ukwenziwa ngokuqhelekileyo kwe-ITU-R BS.1770 / EBU R128 kwimveliso ye MP3, ibeka i- -14 LUFS (isiqhelo sokusasaza), -16 LUFS (isiqhelo sepodcast), okanye -23 LUFS (isiqhelo sencwadi enesandi). Isetyenziswa xa kuguqulwa iingoma ngemiphakamo emininzi yolawulo.

Ingaba i-MP3 iyadlala kwi-iPod / i-app yencwadi enesandi?

I-MP3 idlala kwihlabathi liphela. I-AAC idlala kwi-Apple, i-Android, i-Sonos. I-FLAC idlala kwi-Sonos ne-Android, isebenza kakuhle kwi-iPods edala. Iincwadi zesandi ze-M4B zidlala ngesahluko sokuhamba kwi-iOS Books, i-Audiobookshelf, kunye ne-Smart Audiobook Player. Iinketho eziphambili ziquka i-preset yesixhobo.

Ingaba ifayili yam AAC ifihlakeleyo ngexesha lokuguqulwa?

Ewe — iifayile ezilayishwe phezulu AAC ziqhubekekiswa kubasebenzi abakhethekileyo kwaye zicinywe kwimizuzu. Asiyi kudlala, sigcine, okanye sisebenzise imixholo yesandi. Kubalulekile ngakumbi xa usebenza neelayibrari zencwadi yesandi yobuqu.

Ithatha ixesha elingakanani ukutshintsha i-audiobook ye-10-iyure AAC ukuya kwi-MP3?

I-codec efanayo-i-re-mux: 10-30 imizuzwana. I-re-encode kwi-codec eyahlukileyo: iqhelekileyo 10-20% yobude bomthombo, ngoko ke i-audiobook yeyure ezi-10 igqiba kwimizuzu eyi-60-120. Abaphawuli besihloko baphila kwi-round-trip kwaye bahlukaniswe ngokucocekileyo.

AAC

I-AAC ivelisa iqondo lesandi elingcono kune-MP3 kwinqanaba le-bit elifanayo, elisetyenziswa yi-Apple Music ne-YouTube.

MP3

Iifayile zeMP3 zisebenzisa ucinezelo olulahlekileyo ukunciphisa ubungakanani befayile ngelixa zigcina umgangatho wesandi owamkelekileyo kubaphulaphuli abaninzi.
