M4A ukuba WAV Imibuzo Ebuzwa Rhoqo Ngokuguqula

Ndiyiguqula njani i-M4A yesandi ibe yi-WAV ngaphandle kokulahlekelwa umgangatho?

Layisha phezulu ifayili M4A kwaye umguquli ukhetha WAV i-codec / uthelekiso lwe-bitrate oluhambelana neprofayili yombhali. I-lossless WAV (WAV / FLAC / ALAC) igcina yonke isampuli ngokuchanekileyo; i-lossy WAV (MP3 / AAC / OGG / Opus) imiselwe kwi-192 kbps ebonisa ngokucacileyo imixholo yonke yengoma.

I-WAV ifayili iphela kwi-bitrate enjani?

Okumiselweyo 192 kbps kulahleko WAV; dlula-kwi-lossless WAV. Nciphisa ukuya kwi-320 kbps ukuba ufuna ubukhulu bokungazinzi okulahlekileyo, 128 kbps kunikezelo lwepodcast olukhawulezayo, okanye 96 kbps kumthombo welizwi kuphela apho ifayili encinci ibalulekile ngakumbi kuneenkcukacha zestudio.

Ingaba ukuya ukusuka kwi M4A ukuya kwi WAV kuya kunciphisa ubunjani besandi sam?

Ukuba M4A ilahlekile (MP3, AAC) kwaye WAV ayilahleki (WAV, FLAC), i WAV ayingcono kune M4A — awunakubuyisela ulwazi olusele lulahlekile yi-M4A codec. Ukuba i M4A ayilahleki kwaye WAV iyalahleka, lindele ukuba i WAV encoder iphinde icinezele; kwi-192 kbps ilahleko ayifumaneki kuninzi lweendlebe.

Ingaba i-M4A ukuya kwi-WAV igcina i-ID3 / i-metadata tags?

Ewe — isihloko, umculi, i-albham, unyaka, inani lengoma, ubugcisa be-albham, i-BPM, ukuphinda-udlala-ukufumana kufundwa kwi M4A isiqulathi seefayili kwaye kubhalwa kumacandelo alinganayo kwi WAV isiqulathi seefayili. ID3v2 (MP3), i-Vorbis impendulo (OGG, FLAC), i-MP4 ii-atoms (AAC, M4A), RIFF INFO (WAV), i-iXML i-chunks zonke iimaphu ngokucocekileyo.

Ndingaguqula izigidi zeefayili M4A zibe WAV?

Ewe - susa isiqulathi seefayili se M4A kwifayile kwaye siziqhubekeke ngokuthe tye. I-Premium inemisebenzi ethe tye eninzi kwaye akukho bukhulu befayili nganye obuphezulu, ngoko ke i-500-file batch igqiba kwimizuzu kunokuba i-10s yemizuzu. Ukwakhiwa kwesiqulathi seefayili kugcinwa kwimveliso ye-ZIP.

Ingaba i-WAV iya kugcina inqanaba lesampuli elifanayo njenge-M4A?

Ngokungagqibekanga ewe (a 48 kHz M4A ivelisa 48 kHz WAV, a 44.1 kHz M4A ivelisa 44.1 kHz WAV). Ukulungelelanisa okuthile — umzekelo, ukunyusa isampuli ye-96 kHz studio masters ukuya kwi-44.1 kHz WAV yokukhupha i-CD, okanye ukunyusa isampuli ye-22 kHz yeposi yelizwi ukuya kwi-44.1 kHz WAV — isampuli-ixabiso lokuhla lisebenzisa umgangatho ophezulu we-SOX-style resamply.

Ndingazilungisa njani ilizwi kwinyathelo M4A ukuya kwi WAV?

Ewe - ukhetho lokwenza lusebenze ngokuqhelekileyo ubukhulu busebenzisa ukwenziwa ngokuqhelekileyo kwe-ITU-R BS.1770 / EBU R128 kwimveliso ye WAV, ibeka i- -14 LUFS (isiqhelo sokusasaza) okanye i- -16 LUFS (isiqhelo sepodcast) okanye ixabiso elimiselweyo. Isetyenziswa xa kutshintshwa iingoma ngemiphakamo emininzi yolawulo kwi-WAV yoluhlu lokudlala.

Ingaba i-WAV iya kudlala kwi-stereo yemoto yam / i-iPod / i-Sonos / isithethi se-Bluetooth?

I-MP3 idlala ngokubanzi kwisixhobo ngasinye esiyenziwe kwiminyaka emi-20 edlulileyo. I-AAC idlala kwi-Apple, i-Android, i-Sonos, kunye ne-stereo zemoto zakudala. I-FLAC idlala kwi-Sonos ne-Android ekutshanje, isebenza kakubi kwi-iPods ezidala. I-WAV idlala kuyo yonke into kodwa ifayili ikhulu. Isixhobo-esimiselweyo esithe tyaba sikhetha i-WAV codec ekhuselekileyo ye-platform ocacisayo.

Ingaba ifayili yam M4A ifihlakeleyo ngexesha lokuguqulwa?

Ewe — iifayile ezilayishwe phezulu M4A ziqhubekekiswa kubasebenzi abakhethekileyo kwaye zicinywe kwimizuzu. Asiyi kudlala, sigcine, okanye sisebenzise imixholo yesandi. Inkqubo yokuhambisa iqhuba kwihardware esilawulayo ukusuka ekuqaleni ukuya kwisiphelo; akukho nkonzo yeqela lesithathu ifumana ifayili yakho.

Ithatha ixesha elingakanani ukutshintsha i-M4A yeyure enye ibe yi-WAV?

I-codec efanayo yoku-multiplex (umzekelo. AAC ngaphakathi kwe-M4A -> AAC ngaphakathi kwe-MP4): imizuzwana eyi-10-30. Utshintsho lwe-codec (umzekelo. FLAC -> MP3 okanye WAV -> AAC): ngokuqhelekileyo i-10-20% yobude bomthombo, ngoko ke i-1-iyure M4A -> WAV igqiba kwimizuzu eyi-6-12 kwinkqubo eqhelekileyo yokuhambisa.

Kutheni i-WAV ifayili inamandla okanye ipholile kune-M4A imvelaphi?

Akukho tshintsho lokufumana oluzenzekelayo luza kwenzeka ngaphandle kokuba ukhetho lokumisela uguquko luvuliwe. Ukuba uziva utshintsho lomphakamo, umdlali wakho wesandi okanye ilayibrari yemidiya ingasebenzisa iReplayGain okanye utshintsho lokusebenza oluzenzekelayo kwingoma nganye kumdlalo - khubaza oko kwaye i WAV ithetha ukuba ifana ne-M4A (ukungabikho kolahleko) okanye ifana ngokubonakalayo (ukungabikho kolahleko olucacileyo).

Ndingaguqula i-M4A yokukhuphela ukusuka kwi-Bandcamp / SoundCloud ibe yi-WAV?

Ukuba i-M4A ilayishwe ezantsi ingakhuselwanga (akukho DRM), ewe. Iifayili ezisasazwayo ezifihliweyo ze-DRM (i-Spotify ngaphandle kwe-intanethi, i-Apple Music) zifihliweyo kwinqanaba le-bit kwaye azikwazi kuqhubekekiswa. Amacebo okuthengiswa kwe-Bandcamp, ukulayisha ezantsi kwe-SoundCloud, unikezelo lwepodcast, kunye nokulinganisa komsebenzisi wonke aguqulwa ngokucocekileyo kwi-WAV.

M4A

I-M4A yifomati yefayile yomsindo esondeleleneyo neMP4. Ibonelela ngoxinzelelo oluphezulu lweaudio ngenkxaso yemetadata, iyenza ilungele usetyenziso olwahlukeneyo.

WAV

Iifayile ze-WAV zigcina isandi kwifomathi engacinezelwanga, nto leyo enika isandi esisemgangathweni we-CD esifanelekileyo kumsebenzi wesandi wobuchwephesha.
