WMA ukuba AAC Imibuzo Ebuzwa Rhoqo Ngokuguqula

Ndiyiguqula njani i-WMA yesandi ibe yi-AAC ngaphandle kokulahlekelwa umgangatho?

Layisha phezulu ifayili WMA kwaye umguquli ukhetha AAC i-codec / uthelekiso lwe-bitrate oluhambelana neprofayili yombhali. I-lossless AAC (WAV / FLAC / ALAC) igcina yonke isampuli ngokuchanekileyo; i-lossy AAC (MP3 / AAC / OGG / Opus) imiselwe kwi-192 kbps ebonisa ngokucacileyo imixholo yonke yengoma. I-WMA ilahlekile ngokumiselweyo, kwi-ASF equlethe, eneempawu ezingalahlekiyo kunye nelizwi elilungelelanisiweyo elihlala lichaphazela. I-AAC ilahlekile kodwa isebenza kakuhle kune-MP3, kwaye iphatha ukuya kuthi ga kwi-48 yeendlela eziqhelekileyo kunokuba iboniswe kwi-stereo design.

Ingaba ukutshintsha WMA ukuya ku AAC kujikelezo lwesibini lokucinezela okulahlekileyo?

Ewe, kwaye kufanelekile ukucwangcisa. Zonke iifomati zilahlekile, ngoko ke i AAC encoder isebenza kwisandi esisele sidlula kwindlela enye ye psychoacoustic, kwaye izigqibo zayo zidibanisa iseti yokuqala. Kwi 192 kbps okanye ngaphezulu isiphumo sihlala sicacile kubaninzi bokuziva. Ukuba une master engalahleki naphi na, ukukopela i AAC ukusuka apho endaweni yoko ikhusela i pass kabini ngokupheleleyo.

Kutheni ezinye zeefayili zam WMA azitshintshi?

DRM. Iqela elincinci le WMA iifayile zifihliweyo yindawo yokurhweba 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. WMA ayixhaswanga phantse naphi na ngaphandle Windows, kwaye WMA older iifayili zingathabatha DRM ethintela uguqulo ngokupheleleyo.

I-AAC ifayili iphela kwi-bitrate enjani?

Okumiselweyo 192 kbps kulahleko AAC; dlula-kwi-lossless AAC. 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 WMA ukuya kwi AAC kuya kunciphisa ubunjani besandi sam?

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

Ingaba i-WMA ukuya kwi-AAC igcina i-ID3 / i-metadata tags?

Ewe — isihloko, umculi, i-albham, unyaka, inani lengoma, ubugcisa be-albham, i-BPM, ukuphinda-udlala-ukufumana kufundwa kwi WMA isiqulathi seefayili kwaye kubhalwa kumacandelo alinganayo kwi AAC 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. I-AAC yiNkqubo yoKhuseleko lwesandi esiPhambili, emiselwe ngo-1997 njenge-MPEG-2 Inxalenye ye-7 kwaye icwangciswe ngokucacileyo ukubuyisela i-MP3.

Ewe - susa isiqulathi seefayili se WMA 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-AAC iya kugcina inqanaba lesampuli elifanayo njenge-WMA?

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

Ndingazilungisa njani ilizwi kwinyathelo WMA ukuya kwi AAC?

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

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

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-AAC codec ekhuselekileyo ye-platform ocacisayo. I-AAC ithetha ngokucacileyo ngakumbi kune-MP3 engaphantsi kwe-128 kbps kwaye yindawo emiselweyo yokulandela umkhondo wesandi kwi-MP4, YouTube, Apple Music kunye nokusasazwa. I-AAC ifakwe ipateni, kwaye iqela lee-players ezidala kakhulu zihlala ziyichaza apho bafuna khona i-MP3.

Ingaba ifayili yam WMA ifihlakeleyo ngexesha lokuguqulwa?

Ewe — iifayile ezilayishwe phezulu WMA 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-WMA yeyure enye ibe yi-AAC?

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 WMA -> AAC igqiba kwimizuzu eyi-6-12 kwinkqubo eqhelekileyo yokuhambisa.

WMA
