Ngemuva kokusebenza uthole umhleli efanayo ne TXT / SRT / VTT ukukhishwa njengezo zonke ezinye ifomu kwiwebhusayithi.
Imibuzo ebuzwa kaningi
Ingabe i-M4A ingcono kune-MP3 ekubhaleni?

Yebo. Ukunqoba kokudlala kuvame ukuba yi-codec elahlekile noma i-app engayazi ibhokisi, hhayi ifayela elilahlekile. Ukudluliswa lapha kuqokwa nge-FFmpeg, efunda wonke ama-M4A ahlukene, ngakho-ke ulayishe ngisho uma umdlali wakho wemidiya ephikisana nayo — uma ifayela liyiqiniso, alifundeki, uzothola iphutha elicacile, hhayi ukunqoba okuncane.
Ingabe amafayela we-ALAC (Apple Lossless) axhaswe?
Yebo — i-ALAC iphuma kuleyo.m4a ibhokisi futhi ifaka ikhodi ngendlela efanayo. Khumbula ukuthi umsindo ongenalutho awuthenganga ukunemba okuningi kokukhuluma, futhi amafayela e-ALAC ayizinkulungwane eziningi kuna-AAC, ngakho uma ufaka i-upload size cap, i-AAC export ye-recording efanayo ibhala ngokufanayo.
Ingabe ngizoguqula.m4b amabhuku omsindo?
DRM-free ones, yes:.m4b iyisihlungi esifanayo nesipiliyoni esihlukile, ngakho shintsha igama lefayela libe.m4a futhi uyilayishe. Ubude bubalulekile kunefomethi — 30 imizuzu ngokungezwani, 1 inyanga nge-akhawunti emahhala, 10 inyanga nge-akhawunti ekhokhelwayo — ngakho amabhuku ade ahamba isiqephu ngesiqephu.
