MP4 → WAV

Hayi, kwaye ixabiso lokuba mnyama: akukho nto ingayenza. I MP4 sele ishiye inkcukacha ngexesha lokushicilela kwayo, kwaye ukujika okuseleyo kwi WAV engalahliyo igcina ngokuchanekileyo oko - akukho ngaphezulu. Ifayile ifumana amaxesha amaninzi amakhulu kwaye ithetha ngokufanayo. Ihlala ihamba kakuhle phambi kohlela, kuba WAV ayizukongeza udidi lwesibini lweeartefacts xa urhweba ngaphandle. I-WAV yifomati efanelekileyo yohlela, ulawulo nokugcina, kuba ingaphinde ikhowudiwe nanini na ngaphandle kokudibanisa iindidi. I-MP4 ixhasa kuphela ifomati enye ethandwayo yesihloko esingaphantsi (mov_text), kwaye i-multi-track audio ayithembeki ngaphandle kwee-desktop players.

Ngokungagqibekanga umsinga 0 (umkhondo wokuqala wesandi, ngokuqhelekileyo umxube omkhulu). Ukuba i-MP4 yakho ithatha iinkcazelo, i-dubs, okanye i-audio echazayo kwiimvavanyo ezongezelelweyo, umkhethi ophambili "umsinga wesandi" ukuvumela ukuba ukhethe 1, 2, 3... ngokucacileyo. Uluhlu lwemikhondo luboniswe kwimboniso yokukhuphela ukuze ungakhetha ngokuzifihla.

I-WAV emiselweyo ye-bitrate yi-192 kbps (ibonisa ngaphaya kwengoma kwiimvakalelo ezininzi). Nciphisa kwi-320 kbps yemveliso yeaudiophile, okanye 96-128 kbps yelizwi/ipodcast apho ifayili encinci iphambili. Iinjongo ezingalahlekiyo WAV (WAV, FLAC) zingahoyi isicwangciso se-bitrate kwaye zigcine zonke iiseti. I-WAV igcina i-PCM engacinezelwanga emnyama - yonke isampuli igcinwa ngokuchanekileyo, nakweyiphi na ubunzulu be-bit kunye nesantya sesampuli esithathwe.

Ukuba i WAV ifomati ayilahleki (WAV, FLAC, ALAC), yonke isampuli ebhaliweyo igcinwa. Ukuba i WAV ilahlekile (MP3, AAC, OGG, Opus), i-codec iphinda icinezele - kwi-192 kbps utshintsho aluthethiweyo kwizinto ezininzi; kwi-96 kbps ungava i-cymbals okanye i-sibilants ecocekileyo. I-MP4 isiqwengana asiyi kubangela oku - i-codec kuphela emiselweyo ebalulekileyo.

Ngokungagqibekanga ewe — 48 kHz MP4 isandi siyi 48 kHz WAV isandi, 44.1 kHz siyi 44.1 kHz. Ukuba ufuna ukunyusa isampuli ukuhambelana (umzekelo. 96 kHz studio masters ukuya 44.1 kHz CD-quality WAV) isampuli-rate dropdown yenza oku ngesampuli ephezulu-yexabiso.

Ewe — susa isiqulathi seefayili MP4 kwindawo yokulayisha kwaye siqhube ukususwa ngokuthe tye. I-Premium ifumana abasebenzi abathe tye abaninzi; kwi-100-file batch (uluhlu lwemiculo-ividiyo) le yi-difference phakathi kweemizuzu ezi-90 nemizuzu eli-8.

I-audio demux + transcode iqhuba ngokukhawuleza kunevidiyo yokubuyisela kwikhowudi - ihlala i-5-15% yobude bomthombo. Iyure ye-1 MP4 -> WAV igqiba kwimizuzu ye-3-9 kwindlela eqhelekileyo yokuhambisa. Ukuba i-WAV codec ifana ne-source codec sele kwi-MP4 (eqhelekileyo kwi-AAC ngaphakathi MKV / MP4), yi-remux ecocekileyo kwaye iqhuba kwimizuzu.

Ukuba i-MP4 ifayili igcina i-metadata yokuhamba (umculi, isihloko, i-albham), sikopa ezi ndawo kwi WAV isiqulathi seefayili apho ifomati ixhasa ii-tags. ID3v2 (MP3), i-Vorbis iphawula (OGG, FLAC), i-MP4 i-atoms (AAC / M4A), RIFF INFO (WAV) zonke zibhalwe. I-Untagged MP4 ivelisa i-untagged WAV — sebenzisa i- Mp3tag okanye i-Picard emva-korhwebo ngaphandle ukunika amandla.

Ewe - imodeli yobumfihlo efanayo neyokuguqulwa ngalinye. Umsuka MP4 nemveliso WAV ziqhubekekiswa kubasebenzi abakhuselekileyo kwaye zicinywe kwimizuzu. Asiyi kudlala, sigcine, okanye sisebenzise imixholo. Bona /privacy/.

I-MP4 yakho iqulethe ubeko lwesandi se-multi-track kwaye sakhupha umsinga ongachanekanga (umzekelo, umsinga wesandi ochazayo okhululekileyo endaweni yoxubo oluphambili). Phinda uqhube nge "umsinga wesandi" ophambili okhethwayo omiselwe kwisikhombisi esifanelekileyo, okanye ukhethe "zonke iziqhagamshelanisi" ukukhupha umsinga ngamnye njengefayili ehlukileyo ye WAV.

Ubeko lwesiqhagamshelanisi lulandela i MP4 ngokumiselweyo: 5.1 MP4 umsinga wesandi uvelisa i 5.1 WAV apho i-codec ixhasa khona (AAC, FLAC, OGG, Opus). Ukhetho lwesiqhagamshelanisi-sokunxulumana phantsi lukhuthaza i-stereo okanye i-mono — luncedo kwipodcast yokuhamba komsebenzi okanye ukuhambelana ne-mono kuphela i-Bluetooth speakers.
