DivX → MP3

Ndikukhulupirira kuti ndinu oyenera, ndipo ndibwino kuti mupange. Mafomu awiriwa ndi owonongeka, choncho MP3 encoder akuchita ntchito kuchokera ku audio yomwe yakhala ikuyenda mwa psychoacoustic pass, ndipo masankho ake oyamba amapanga gawo loyamba. Pa 192 kbps kapena pamwambapa, zotsatirazi ndizosawoneka bwino kwa ambiri owerenga. Ngati muli ndi master yopanda kuwonongeka, kulemba koyamba kwa MP3 kuchokera ku yomwe imalepheretsa kupitanso koyamba. DivX zinthu ndi MPEG-4 Part 2 kanema, nthawi zambiri anapaka mu AVI, ndi MP3 kapena AC-3 audio mbali yake. MP3 ndi lossy: psychoacoustic model amachotsa ma frequencies kuti nkhope sizingayembekezere kuti adziwe, makamaka pa 128 mpaka 320 kbps.

Idzaikidwa pansi pa stereo, chifukwa MP3 siyimakhala ndi njira yogwiritsira ntchito ma channel ambiri. Kulowetsa kumagwiritsa ntchito ma coefficients ovomerezeka kuti ma channel apakati azikhala owoneka bwino ndipo ma surrounds amaphatikizidwa pamalingaliro otsika. Chomwecho chilichonse chomwe chimadalirika pa malo osiyanasiyana a ma channel chimapita pamene izi zikuchitika. MP3 ndi mwaukadaulo outclassed ndi AAC ndi Opus pa zonse bitrate, sangathe kusungira zambiri kuposa awiri ma channels bwino, ndi nthawi zonse amawonjezera m'badwo wa encoder.

Maakaunti aulere amafika pa 100 MB pa fayilo, ndipo DivX mabungwe amagwira ntchito kwambiri chifukwa mtunduwo umabweretsa ndalama zochuluka pazinthu zowonjezera pavidiyo. Premium imatulutsa katundu kwambiri. Ngati fayilo igawidwa m'magawo owerengeka chifukwa cha mtundu wamtundu, tsitsani limodzi ndipo amachitidwa ngati ntchito imodzi. DivX amafuna pafupifupi katatu bitrate wa H.264 kwa mtundu wofanana ndi palibe njira kwa HDR, 10-bit mtundu kapena resolutions m'munsi 1080p.

Poyambira, mpweya 0 (woyamba wa nyimbo, nthawi zambiri ndi woyamba kuphatikizidwa). Ngati DivX wanu ali ndi mawu ofotokoza, ma dubbing, kapena mawu ofotokoza pa nyimbo zina, wosankha "mpweya wa nyimbo" akukulola kusankha 1, 2, 3... mwatsatanetsatane. Lipoti la nyimbo limawonekera pa mndandanda woyang'anira kuti musasankhe mwamsanga.

Default MP3 bitrate ndi 192 kbps (wowoneka bwino kwa nyimbo kwa amayi ambiri). Kusintha kwa 320 kbps kwa audiophile output, kapena 96-128 kbps kwa mawu / podcast komwe fayilo yaying'ono ndi yoyamba. Ma MP3 opanda malire (WAV, FLAC) sasamala za kukhazikitsa kwa bitrate ndikusunga zonse.

Ngati MP3 ndi mtundu wopanda kuwonongeka (WAV, FLAC, ALAC), zonse zomwe zimapangidwa zimasungidwa. Ngati MP3 ndi zowonongeka (MP3, AAC, OGG, Opus), codec imabwezeretsa - pa 192 kbps kusiyana kumakhala kopanda kudziwika kwa zinthu zambiri; pa 96 kbps mutha kunena kuti ma cymbals kapena ma sibilants amawoneka. DivX yokhala ndi DivX siyikhudza izi - zosankha za codec ndizofunikira.

Mwa default yes — 48 kHz DivX audio imakhala 48 kHz MP3 audio, 44.1 kHz imakhala 44.1 kHz. Ngati mukufuna kuchepetsa kusamvana kwa kugwirizana (mwachitsanzo, 96 kHz studio masters ku 44.1 kHz CD-quality MP3) mndandanda wolowetsa wa sampling-rate amachita izi ndi kusamvana kwabwino.

Yai - chotsani fayilo ya DivX ku gawo lotsitsa ndipo tidzachita kutulutsa mofanana. Premium imalandira ogwira ntchito ambiri mofanana; pa fayilo ya 100 (kusonkhanitsa kwa nyimbo za nyimbo) iyi ndi kusiyana pakati pa masekondi a 90 ndi maola a 8.

Audio demux + transcode imayenda mwachangu kuposa kubwezeretsa kanema - nthawi zambiri 5-15% ya nthawi yoyambira. 1-hour DivX -> MP3 imatha m'maola 3-9 pa standard pipeline. Ngati MP3 codec imagwirizana ndi codec yoyambira yomwe ili mu DivX (yofala kwa AAC m'ma MKV / MP4), ndi remux yoyera ndipo imagwira ntchito m'masekondi.

Ngati fayilo ya DivX imasunga metadata ya stream (mlengi, mutu, album), timakopera masambawa ku MP3 komwe mtundu umathandizira ma tag. ID3v2 (MP3), Vorbis comments (OGG, FLAC), MP4 atoms (AAC / M4A), RIFF INFO (WAV) onse amalemba. Opanda ma tag DivX amapanga MP3 osadziwika - kugwiritsa ntchito Mp3tag kapena Picard kutumiza kunja kuti muwonjezere.

Yes - mtundu wofanana wa privacy monga pazosintha zonse. Source DivX ndi output MP3 amachitidwa m'mabungwe osiyana ndipo amasungidwa m'maola ochepa. Sitimasewera, sitisunga kapena sitigawana zinthu.
