AAC ilinganiswe no M4A: ulwanelisaniso lwefomathi
Indlela iifomathi ezimbini ezahlukana ngayo kwizinto ezitshintsha isiphumo sakho.
| Inkcazelo Yefomathi | AAC (umthombo) | M4A (isiphumo) |
|---|---|---|
| I-Container | ADTS / raw AAC | MPEG-4 Part 14 |
| Yenziwe ngu- | MPEG / Fraunhofer IIS | Apple / MPEG |
| Qaqambiswa | 1997 | 2003 |
| Iikodeki zomsindo | AAC-LC, HE-AAC | AAC-LC, HE-AAC, ALAC |
| Ucinezelo | Enolahlekelelo | Kuxhomekeke kwi-codec |
| I-bitrate eqhelekileyo yomsindo | 96–256 kbps | 96–256 kbps |
| I-sample rate ephezulu kakhulu | 96 kHz | 96 kHz |
| Amakhaneli aphezulu kakhulu | 8 | 8 |
| Ukudlala Ngaphandle Kwezithuba | Inxalenye | Ewe |
| Idatha Yenkcazelo / Iitegi | ID3v2 (limited in ADTS) | MPEG-4 iTunes-style atoms |
| Malunga Nobungakanani Befayile | 0.72–1.92 MB ngeyure enye | 0.72–1.92 MB ngeyure enye |
| Ilayisensi | Inelayisensi Yepatenti | Inelayisensi Yepatenti |
| Idlala Ngokwemvelo Kwi- | Ngokwemvelo: Iibhrawuza Zewebhu, Windows, macOS, iOS, Android, AmaSmart TVs | Ngokwemvelo: Iibhrawuza Zewebhu, Windows, macOS, iOS, Android, AmaSmart TVs |
| Kulungele Ikakhulu | iinkonzo zokusasaza, ukudlalwa kwiselfowuni, ukusasaza | i-ecosystem ye-Apple, iilayibrari zomculo, iincwadi zomsindo |
Kuthini oyohluka xa uguqula AAC iye kwi M4A
Qaphela ukuba i-MPEG-4 Part 14 ayithetheli khowudi enye ethile. Inokugubungela i-AAC-LC, HE-AAC, ALAC, ngoko indlela yocinezelo yesiphumo ixhomekeke kwi-codec ekhethiweyo hayi kuphela kuhlobo lwefayile.
Olu guqulelo lususa ifayile iye kwenye injongo: i-AAC ilungele i-iinkonzo zokusasaza, ukudlalwa kwiselfowuni, ukusasaza, ngelixa i-M4A ikhethelwa i-i-ecosystem ye-Apple, iilayibrari zomculo, iincwadi zomsindo.
Iitegi azidluliseli ngqo. I-AAC izigcina njenge-ID3v2 (limited in ADTS) ngelixa i-M4A isebenzisa i-MPEG-4 iTunes-style atoms, ngoko izihloko kunye nemifanekiso ziyaguqulwa yaye amathuba acetyiweyo angaqhelekanga asenokungasindi.
Malunga Nokuguqulwa kwe-AAC kuya kwi-M4A
Ukuguqula i-AAC ibe yi-M4A kuthetha ukusuka nomsindo kwi-container ye-ADTS / raw AAC, eyaqalwa ngo-1997, usiya kwi-MPEG-4 Part 14, eyafika ngo-2003. Ezi zimbini zenzelwe iinjongo ezahlukeneyo, kwaye yiloo nto exela ukuba olu guqulelo luya kukubiza ngomgangatho, ngendawo yokugcina, okanye ngokuhambelana.
Yaphuhliswa ngu-MPEG / Fraunhofer IIS ngo-1997, i-AAC igcina umsindo isebenzisa i-AAC-LC, HE-AAC. Olo khetho lwe-codec lumisela umda ophezulu woko naluphi na uguqulelo olunokulugcina.
I-M4A, evela ku-Apple / MPEG yaza yaqalwa ngo-2003, isebenzisa i-AAC-LC, HE-AAC, ALAC kwaye idlala ngokwemvelo kwi-6 yeendidi ezintandathu zeeplatform esizilandelayo. Oko kudityaniswa kuhlala kuyimbangela yokuba abantu baguqulele kuyo.
Emva kokuguqula ifayile yakho, ungasebenzisa iinkonzo zokubhala phantsi zeScriptivox ukuguqula i-odiyo yakho ibe ngumbhalo. Ilungele iintlanganiso, udliwano-ndlebe, iipodkhasti, nokunye okuninzi.
