M4A ilinganiswe no AAC: ulwanelisaniso lwefomathi
Indlela iifomathi ezimbini ezahlukana ngayo kwizinto ezitshintsha isiphumo sakho.
| Inkcazelo Yefomathi | M4A (umthombo) | AAC (isiphumo) |
|---|---|---|
| I-Container | MPEG-4 Part 14 | ADTS / raw AAC |
| Yenziwe ngu- | Apple / MPEG | MPEG / Fraunhofer IIS |
| Qaqambiswa | 2003 | 1997 |
| Iikodeki zomsindo | AAC-LC, HE-AAC, ALAC | AAC-LC, HE-AAC |
| Ucinezelo | Kuxhomekeke kwi-codec | Enolahlekelelo |
| 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 | Ewe | Inxalenye |
| Idatha Yenkcazelo / Iitegi | MPEG-4 iTunes-style atoms | ID3v2 (limited in ADTS) |
| 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 | i-ecosystem ye-Apple, iilayibrari zomculo, iincwadi zomsindo | iinkonzo zokusasaza, ukudlalwa kwiselfowuni, ukusasaza |
Kuthini oyohluka xa uguqula M4A iye kwi AAC
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-M4A ilungele i-i-ecosystem ye-Apple, iilayibrari zomculo, iincwadi zomsindo, ngelixa i-AAC ikhethelwa i-iinkonzo zokusasaza, ukudlalwa kwiselfowuni, ukusasaza.
Iitegi azidluliseli ngqo. I-M4A izigcina njenge-MPEG-4 iTunes-style atoms ngelixa i-AAC isebenzisa i-ID3v2 (limited in ADTS), ngoko izihloko kunye nemifanekiso ziyaguqulwa yaye amathuba acetyiweyo angaqhelekanga asenokungasindi.
Malunga Nokuguqulwa kwe-M4A kuya kwi-AAC
Ukuguqula i-M4A ibe yi-AAC kuthetha ukusuka nomsindo kwi-container ye-MPEG-4 Part 14, eyaqalwa ngo-2003, usiya kwi-ADTS / raw AAC, eyafika ngo-1997. Ezi zimbini zenzelwe iinjongo ezahlukeneyo, kwaye yiloo nto exela ukuba olu guqulelo luya kukubiza ngomgangatho, ngendawo yokugcina, okanye ngokuhambelana.
Yaphuhliswa ngu-Apple / MPEG ngo-2003, i-M4A igcina umsindo isebenzisa i-AAC-LC, HE-AAC, ALAC. Olo khetho lwe-codec lumisela umda ophezulu woko naluphi na uguqulelo olunokulugcina.
I-AAC, evela ku-MPEG / Fraunhofer IIS yaza yaqalwa ngo-1997, isebenzisa i-AAC-LC, HE-AAC 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.
