WMA ukuba M4A Imibuzo Ebuzwa Rhoqo Ngokuguqula

Yintoni eyenza i-WMA ukuya kwi-M4A iguquli sesandi?

Ingaba inqanaba lesampuli kunye nobeko lwesiqhagamshelanisi ziya kugcinwa?

Ngokungagqibekanga ewe — i-stereo ihlala i-stereo, i-sample rate emiselweyo (44.1 kHz, 48 kHz, njl.njl.) idluliselwa kwi-M4A output.

Ingaba ukuguqulwa kwe-WMA ukuya kwi-M4A kunokuphinda kuphindeke?

Ungaguqula i-M4A kwakhona kwi-WMA kule ndawo. Ukuba nayiphi na ifomati ebandakanyiweyo ilahlekile, i-round-trip ayizukuba yi-bit-perfect nakuba ibonakalayo okanye icacile.

Yintoni umgangatho wemveliso endingalindele ukuba ndiyilindele ukusuka kwi-WMA ukuya kwi-M4A?

Izicwangciso ezimiselweyo zijolise kwi-broadcast / umgangatho we-web - ngokubonakalayo ifana nomcebo kubabukeli abaninzi. Ukusetyenziswa kovimba, khetha ukhetho oluphezulu lomgangatho kwimimiselo yoguquli.

Ingaba ukutshintsha WMA ukuya M4A kukwindawo yesibini yokucinezela okulahlekileyo?

Isiqulathi seefayili esinomsindo ngaphakathi kwayo, kunokuba umsindo ngokwawo. Lo maleko ongaphezulu yindawo apho ubude, isalathisi sokukhangela kunye ne metadata yefomati echazayo igcinwa khona, ngoko umdlali uyazi ukuba i M4A ihlala ixesha elingakanani phambi kokucoda iframe enye endaweni yokukhangela ifayile yonke ukufumanisa. Oku kuthetha ukuba unikezelo alusoloko lugqiba into engaphakathi: iziqulathi zeefayili ezininzi ezinjalo zivunyelwe ukuba zigcine ngaphezulu kwesinye isifo sesandi, oko kukuthi, iifayile ezimbini M4A zingaziphatha ngokuhlukileyo ngelixa zijonge ngaphaya.

Ezininzi zeefayili zam WMA zavela kwiCDs - ngaba oku kubaluleke apha?

Kuphela ukuba ukukopela sele kwenzeka kabini. A WMA okutshatywa kwi diski wacinezelwa nakweyiphi na i bitrate i ripper icwangciswe kwiminyaka edlulileyo, kwaye oko kumgangatho kwizinto zonke ezantsi - ukuguqula akukwazi ukubuyisela into i ripper eshiyekayo. Ukuba i diski ihlala kwi shelf, ukuphinda ukhuphe kwifomati engalahlekiyo nokukhowuda ukusuka apho kunika isiphumo esingcono kunanoma iyiphi ukuguqulwa kwefayile ezikhoyo. I-WMA yiWindows Media Audio, iMicrosoft's answer to MP3, yasungulwa ngo-1999 kwaye yadityaniswa neWindows nganye efakwe kulo nyaka.

I-codec iquka i-patent pools, kwaye ilayisensi ibekwe ngumthumeli we-decoder - ifowuni, umkhangeli zincwadi, inkqubo yokusebenza - ixesha elide phambi kokuba ifayile ifike kuwe. Yiyo loo nto ifomati ikho kuyo yonke indawo kwihardware, kwaye kutheni i royalty- free alternatives yakhiwa naphi na. Ayitshintshanga nto malunga nokutshintsha ifayile oyinayo, kwaye kumbuzo ophilayo kuphela ukuba uthumeli i-encoder ngokwakho.
