M4A ukuba WMA Imibuzo Ebuzwa Rhoqo Ngokuguqula

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

It re-encodes a M4A audio file as WMA. Sample rate and channel count are preserved; the difference is the codec and container.

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-WMA output.

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

Ungaguqula i-WMA kwakhona kwi-M4A 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-M4A ukuya kwi-WMA?

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

Ingaba ukutshintsha M4A ukuya WMA kukwindawo yesibini yokucinezela okulahlekileyo?

Ewe, kwaye kufanelekile ukucwangcisa. Zonke iifomati zilahlekile, ngoko ke i WMA encoder isebenza kwisandi esisele sidlula kwindlela enye ye psychoacoustic, kwaye izigqibo zayo zidibanisa iseti yokuqala. Kwi 192 kbps okanye ngaphezulu impumelelo ihlala icacile kubaninzi bokuziva. Ukuba une master engalahleki naphi na, ukukopela i WMA ukusuka apho endaweni yoko ikhusela i pass kabini ngokupheleleyo. I-M4A igcina i-AAC kwiziganeko ezininzi, okanye i-Apple Lossless (ALAC) xa ivela kwi-rip engalahlekiyo. I-WMA ilahlekile ngokumiselweyo, kwi-ASF equlethe, eneempawu ezingalahlekiyo kunye nelizwi elilungelelanisiweyo elihlala lichaphazela.

Yintoni na i-WMA ifayili?

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 WMA 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 WMA zingaziphatha ngokuhlukileyo ngelixa zijonge ngaphaya.

Kutheni le nto ifowuni yam okanye i-tablet irekhoda kwi M4A?

Kuba yiyo loo nto i-hardware encoder kwisixhobo ivelisa. Ii-memos zelizwi, ukurekhodwa kwesikrini kunye nokulandela umkhondo wesandi wento erekhodwe kwifowuni ziphuma njenge M4A ngaphandle kokuba umntu ukhetha, oko kukuthi kutheni iifayile ezininzi zifika kuyo kwaye kutheni umgangatho uhlala ungcono kune-ubungakanani befayili ebonisa. Akukho nto malunga nayo imisa ukutshintsha; oku kuthetha kuphela ukuba umthombo wakhowudiwe kabini, yi-chip elungele ukuphila kwebhetri kunokuba kuthembekile. I-M4A yi-MP4 equlethe i-audio kuphela, kwaye yiyo into eyenza i-iTunes, i-Apple Music kunye ne-iPhone Voice Memos app.

Kutheni ezinye zeefayili zam M4A zingaguqulwa?

DRM. Iqela elincinci le M4A iifayile zifihliweyo yindawo yokuthenga 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.

Ingaba i WMA iyadlala kwimoto yam okanye kwizixhobo ezidala?

Ininzi ingxaki. M4A ikhowudiwe yiyo yonke into, kubandakanya imoto yeqela lenjongo ethile kunye nabadlali abadala; WMA ifuna udweliso lwenkqubo oluzi ikhowudi, eyona hardware ekhululekileyo ihlala ingakho. Ukuba indawo efanelekileyo yimoto ye stereo okanye umdlali ophathekayo, oku kuyinyani enamandla yokuhlala kwi M4A. WMA ayixhaswanga phantse naphi na ngaphandle Windows, kwaye WMA older iifayili zingathabatha DRM ethintela uguqulo ngokupheleleyo.

Ingaba kukho ilayisensi edityaniswe ne M4A?

Akukho nto ofuna ukuyicinga. 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.

Ingaba kukho umda wobungakanani befayili xa uguqula i-M4A ibe yi-WMA?

Ulayisho phezulu olungaziwayo luphelelwe lixesha ngokumiselweyo; i-akhawunti ebhalisiweyo ekhululekileyo ifumana umda ophezulu, kwaye i-akhawunti ye-Pro ayinalo umda wefayili nganye. Inkumbulo yesikhangeli sihlala siyimfuneko yothintelo ixesha elide phambi kokuba umda wethu we-server-side uqale.

Ndingaguqula iifayili ezininzi ze-M4A zibe yi-WMA ngaxeshanye?

Ewe. Nqumle okanye ukhethe iifayile ezininzi ze M4A kwifayili enye yokulayisha - umguquli uqhubekeka nazo ngokuthe tye kwaye ubuyisele i-ZIP yeziphumo ze WMA. Akukho mfuneko yokuphinda uqhubekeke inkqubo yefayili nganye.
