FLV → MP3

Ewe, kwaye kufanelekile ukucwangcisa. Zonke iifomati zilahlekile, ngoko ke i MP3 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 MP3 ukusuka apho endaweni yoko ikhusela i pass kabini ngokupheleleyo. I-FLV ihlala igcina i-Sorrenson Spark okanye i-H.264 video ene-MP3 okanye i-AAC yesandi, ejikelezwe kwifomati yokuhamba eyenziweyo yokuhambisa i-RTMP. I-MP3 ilahlekile: imodeli ye-psychoacoustic isusa ukuphindaphinda indlebe ayikwazi ukuqaphela, ihlala kwi-128 ukuya kwi-320 kbps.

Ewe, kwaye yimpumelelo epheleleyo ngaphezulu kwe FLV, eyona ingekho naphi na ethembekileyo ukugcina nayiphi na. MP3 ithatha isihloko, umculi, i-albham, unyaka, inani lengoma kunye nobugcisa bokuqhoboshela okufakwe kwisiqulathi seefayili, ngoko ithala leencwadi lengoma liyifaka ngokuchanekileyo ngaphandle kokuhamba ngesandla. Akukho nto ibetha iMP3 ekusebenzeni kwayo - iistereo zemoto, izixhobo zegym, iiDAPs kunye nezixhobo zekhompyutha ezineminyaka engama-20 ubudala zonke zifunda ngaphandle kwemibuzo.

Ngokungagqibekanga umsinga 0 (umkhondo wokuqala wesandi, ngokuqhelekileyo umxube omkhulu). Ukuba i-FLV 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-MP3 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 MP3 (WAV, FLAC) zingahoyi isicwangciso se-bitrate kwaye zigcine zonke iiseti.

Ukuba i MP3 ifomati ayilahleki (WAV, FLAC, ALAC), yonke isampuli ebhaliweyo igcinwa. Ukuba i MP3 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-FLV isiqwengana asiyi kubangela oku - i-codec kuphela emiselweyo ebalulekileyo.

Ngokungagqibekanga ewe — 48 kHz FLV isandi siyi 48 kHz MP3 isandi, 44.1 kHz siyi 44.1 kHz. Ukuba ufuna ukunyusa isampuli ukuhambelana (umzekelo. 96 kHz studio masters ukuya 44.1 kHz CD-quality MP3) isampuli-rate dropdown yenza oku ngesampuli ephezulu-yexabiso.

Ewe — susa isiqulathi seefayili FLV 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 FLV -> MP3 igqiba kwimizuzu ye-3-9 kwindlela eqhelekileyo yokuhambisa. Ukuba i-MP3 codec ifana ne-source codec sele kwi-FLV (eqhelekileyo kwi-AAC ngaphakathi MKV / MP4), yi-remux ecocekileyo kwaye iqhuba kwimizuzu.

Ukuba i-FLV ifayili igcina i-metadata yokuhamba (umculi, isihloko, i-albham), sikopa ezi ndawo kwi MP3 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 FLV ivelisa i-untagged MP3 — sebenzisa i- Mp3tag okanye i-Picard emva-korhwebo ngaphandle ukunika amandla.

Ewe - imodeli yobumfihlo efanayo neyokuguqulwa ngalinye. Umsuka FLV nemveliso MP3 ziqhubekekiswa kubasebenzi abakhuselekileyo kwaye zicinywe kwimizuzu. Asiyi kudlala, sigcine, okanye sisebenzise imixholo. Bona /privacy/.

I-FLV 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 MP3.
