M4A ukuba MP3 Imibuzo Ebuzwa Rhoqo Ngokuguqula

Ndiyiguqula njani i-M4A yesandi ibe yi-MP3 ngaphandle kokulahlekelwa umgangatho?

Layisha phezulu ifayili M4A kwaye umguquli ukhetha MP3 i-codec / uthelekiso lwe-bitrate oluhambelana neprofayili yombhali. I-lossless MP3 (WAV / FLAC / ALAC) igcina yonke isampuli ngokuchanekileyo; i-lossy MP3 (MP3 / AAC / OGG / Opus) imiselwe kwi-192 kbps ebonisa ngokucacileyo imixholo yonke yengoma. I-M4A igcina i-AAC kwiziganeko ezininzi, okanye i-Apple Lossless (ALAC) xa ivela kwi-rip engalahlekiyo. I-MP3 ilahlekile: imodeli ye-psychoacoustic isusa ukuphindaphinda indlebe ayikwazi ukuqaphela, ihlala kwi-128 ukuya kwi-320 kbps.

Ingaba ukutshintsha M4A 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.

Ithini into ebangela ukuba i-multichannel yesandi iguqulwe kwi M4A 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.

Kutheni ezinye zeefayili zam M4A azitshintshi?

DRM. Iqela elincinci le M4A iifayile zifihliweyo yindawo yokurhweba okanye isoftware ekhupheleyo, kwaye umsindo ofihliweyo awunakucinywa uphawu nganoma uphi umguquli. Nantoni na oyiyikhuphe ngokwakho, uyirekhode, okanye uyithengise ngaphandle kokhuselo iguqula ngokuqhelekileyo; ukuthengiswa kwelayisensi akuyi kwenza njalo. M4A ifihla izinto ezimbini ezihlukileyo eziphambili kwesinye isiqalo — lossy AAC kunye lossless ALAC — kwaye i-Apple engasebenziyo hardware inkxaso ayihambelani.

I-MP3 ifayili iphela kwi-bitrate enjani?

Okumiselweyo 192 kbps kulahleko MP3; dlula-kwi-lossless MP3. Nciphisa ukuya kwi-320 kbps ukuba ufuna ubukhulu bokungazinzi okulahlekileyo, 128 kbps kunikezelo lwepodcast olukhawulezayo, okanye 96 kbps kumthombo welizwi kuphela apho ifayili encinci ibalulekile ngakumbi kuneenkcukacha zestudio.

Ingaba ukuya ukusuka kwi M4A ukuya kwi MP3 kuya kunciphisa ubunjani besandi sam?

Ukuba M4A ilahlekile (MP3, AAC) kwaye MP3 ayilahleki (WAV, FLAC), i MP3 ayingcono kune M4A — awunakubuyisela ulwazi olusele lulahlekile yi-M4A codec. Ukuba i M4A ayilahleki kwaye MP3 iyalahleka, lindele ukuba i MP3 encoder iphinde icinezele; kwi-192 kbps ilahleko ayifumaneki kuninzi lweendlebe.

Ingaba i-M4A ukuya kwi-MP3 igcina i-ID3 / i-metadata tags?

Ewe — isihloko, umculi, i-albham, unyaka, inani lengoma, ubugcisa be-albham, i-BPM, ukuphinda-udlala-ukufumana kufundwa kwi M4A isiqulathi seefayili kwaye kubhalwa kumacandelo alinganayo kwi MP3 isiqulathi seefayili. ID3v2 (MP3), i-Vorbis impendulo (OGG, FLAC), i-MP4 ii-atoms (AAC, M4A), RIFF INFO (WAV), i-iXML i-chunks zonke iimaphu ngokucocekileyo. I-MP3 yi-MPEG-1 Umphezulu Wosandi III, egqityiwe ngo-1993, kwaye ihlala i-format yesandi ekwazi ukucoda ngokupheleleyo ekhoyo.

Ndingaguqula izigidi zeefayili M4A zibe MP3?

Ewe - susa isiqulathi seefayili se M4A kwifayile kwaye siziqhubekeke ngokuthe tye. I-Premium inemisebenzi ethe tye eninzi kwaye akukho bukhulu befayili nganye obuphezulu, ngoko ke i-500-file batch igqiba kwimizuzu kunokuba i-10s yemizuzu. Ukwakhiwa kwesiqulathi seefayili kugcinwa kwimveliso ye-ZIP.

Ingaba i-MP3 iya kugcina inqanaba lesampuli elifanayo njenge-M4A?

Ngokungagqibekanga ewe (a 48 kHz M4A ivelisa 48 kHz MP3, a 44.1 kHz M4A ivelisa 44.1 kHz MP3). Ukulungelelanisa okuthile — umzekelo, ukunyusa isampuli ye-96 kHz studio masters ukuya kwi-44.1 kHz MP3 yokukhupha i-CD, okanye ukunyusa isampuli ye-22 kHz yeposi yelizwi ukuya kwi-44.1 kHz MP3 — isampuli-ixabiso lokuhla lisebenzisa umgangatho ophezulu we-SOX-style resamply.

Ndingazilungisa njani ilizwi kwinyathelo M4A ukuya kwi MP3?

Ewe - ukhetho lokwenza lusebenze ngokuqhelekileyo ubukhulu busebenzisa ukwenziwa ngokuqhelekileyo kwe-ITU-R BS.1770 / EBU R128 kwimveliso ye MP3, ibeka i- -14 LUFS (isiqhelo sokusasaza) okanye i- -16 LUFS (isiqhelo sepodcast) okanye ixabiso elimiselweyo. Isetyenziswa xa kutshintshwa iingoma ngemiphakamo emininzi yolawulo kwi-MP3 yoluhlu lokudlala.

Ingaba i-MP3 iya kudlala kwi-stereo yemoto yam / i-iPod / i-Sonos / isithethi se-Bluetooth?

I-MP3 idlala ngokubanzi kwisixhobo ngasinye esiyenziwe kwiminyaka emi-20 edlulileyo. I-AAC idlala kwi-Apple, i-Android, i-Sonos, kunye ne-stereo zemoto zakudala. I-FLAC idlala kwi-Sonos ne-Android ekutshanje, isebenza kakubi kwi-iPods ezidala. I-WAV idlala kuyo yonke into kodwa ifayili ikhulu. Isixhobo-esimiselweyo esithe tyaba sikhetha i-MP3 codec ekhuselekileyo ye-platform ocacisayo. Akukho nto ibetha iMP3 ekusebenzeni kwayo - iistereo zemoto, izixhobo zegym, iiDAPs kunye nezixhobo zekhompyutha ezineminyaka engama-20 ubudala zonke zifunda ngaphandle kwemibuzo.

Ingaba ifayili yam M4A ifihlakeleyo ngexesha lokuguqulwa?

Ewe — iifayile ezilayishwe phezulu M4A ziqhubekekiswa kubasebenzi abakhethekileyo kwaye zicinywe kwimizuzu. Asiyi kudlala, sigcine, okanye sisebenzise imixholo yesandi. Inkqubo yokuhambisa iqhuba kwihardware esilawulayo ukusuka ekuqaleni ukuya kwisiphelo; akukho nkonzo yeqela lesithathu ifumana ifayili yakho.

M4A

I-M4A yifomati yefayile yomsindo esondeleleneyo neMP4. Ibonelela ngoxinzelelo oluphezulu lweaudio ngenkxaso yemetadata, iyenza ilungele usetyenziso olwahlukeneyo.

MP3

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