M4A ukuba WAV Imibuzo Ebuzwa Rhoqo Ngokuguqula

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

M4A sele ilahlekile, ngoko ukuguqula kwi WAV igcina isandi esisekho ngaphandle kokunyuka ezantsi, kodwa ayikwazi ukubuyisela inkcukacha ezilahlekileyo kwikhowudi yokuqala. WAV ilungile ukuba ucwangcisa ukuhlela nokugcina kwakhona ngaphandle kokudibanisa ii-artifacts zokucinezela.

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-WAV output.

Ingaba ifayili ye WAV izakuba mkhulu kakhulu kunesiqulathi seefayili se M4A?

Ewe - isandi esingalahlekiyo sihlala singaphezulu nge-5-10x kunesandi esilahlekileyo kwinqanaba lomgangatho ofanayo. Phanda i ~10 MB ngomzuzu ngamnye kwi-WAV versus ~1 MB ngomzuzu ngamnye kwi-high-bitrate M4A.

Ingaba i-WAV iya kuba banzi kune-M4A?

Ewe — iziqulatho ezingalahleki zigcina i-byte nganye. Lindela ukuba i-WAV ibe yi-3-8x ubungakanani be-M4A. Inyani kukuba akukho kufumana kwakhona umgangatho xa uhlela okanye uphinde ubhale kwakhona ikhowudi.

Ingaba ukutshintsha M4A ukuya ku WAV kunyusa umgangatho wesandi?

Hayi, kwaye ixabiso lokuba mnyama: akukho nto ingayenza. I M4A sele ishiye inkcukacha ngexesha lokushicilela kwayo, kwaye ukujikelezisa okuseleyo kwi WAV engalahliyo igcina ngokuchanekileyo oko - akukho ngaphezulu. Ifayile ifumana amaxesha amaninzi akhulu kwaye ithetha ngokufanayo. Iyaqhubeka intshukumo elungileyo phambi kohlela, kuba WAV ayizukongeza udidi lwesibini lwe artefacts xa urhweba ngaphandle. I-WAV yifomati efanelekileyo yohlela, ulawulo nokugcina, kuba ingaphinde ikhowudiwe nanini na ngaphandle kokudibanisa iindidi. M4A ifihla izinto ezimbini ezihlukileyo eziphambili kwesinye isiqalo — lossy AAC kunye lossless ALAC — kwaye i-Apple engasebenziyo hardware inkxaso ayihambelani.

Ingaba izihloko zam zengoma kunye nemifanekiso ye-albhamu iya kuqhubeka i M4A ukuya ku WAV uguqulelo?

Ayiqhelekanga. M4A ihambisa i-metadata efanelekileyo, kodwa WAV ayinandawo eqhelekileyo yomsebenzi womculi, i-albham, inani lengoma okanye ubugcisa besiqhoboshi, ngoko ke iimpawu zilahliwe endaweni yokulahleka. Gcina i M4A njengekopi ephawulweyo, okanye uphinde uphawule emva kwesixhobo njenge Mp3tag okanye i MusicBrainz Picard. I-WAV inamandla amakhulu - malunga ne-10 MB ngemizuzu ye-stereo kwi CD elungileyo - kwaye i-classic format ine-4 GB ye-ceiling kwaye akukho ndawo ye tags efanelekileyo.

Yintoni na i-WAV 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 WAV 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 WAV zingaziphatha ngokuhlukileyo ngelixa zijonge ngaphaya. I-WAV igcina i-PCM engacinezelwanga emnyama - yonke isampuli igcinwa ngokuchanekileyo, nakweyiphi na ubunzulu be-bit kunye nesantya sesampuli esithathwe.

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.

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-WAV?

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-WAV ngaxeshanye?

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