Kulephera kopanda malire (AC3 = WAV / FLAC / ALAC) kumateteza chilichonse; kulephera kopanda malire (AC3 = MP3 / AAC / OGG) kumasinthidwa ku 192 kbps komwe kumawoneka bwino kwa audiobooks olankhula ndi nyimbo zambiri.

Kodi kusinthira AMR ku AC3 ndi gawo lachiwiri la kutsitsa kwa lossy?

Ndikukhulupirira kuti ndinu oyenera, ndipo ndibwino kuti mupange. Mafomu awiriwa ndi owonongeka, choncho AC3 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 kusowa, kulemba koyamba kwa AC3 kuchokera ku yomwe imalepheretsa kupita kwachiwiri kwathunthu. AMR ndi narrowband mawu codec kuyendetsa pakati pa 4.75 ndi 12.2 kbps, modeling munthu woimba m'mimba kuposa wonse audio spectrum. AC-3 ndi lossy multichannel audio, nthawi zambiri 5.1 pa 384 kapena 448 kbps, ndi metadata kwa dialogue normalization ndi downmixing.

N’chifukwa chiyani nyimbo zimawoneka zoipa kwambiri pa chikhulupiriro?

Chifukwa chimodzi mwazigawo zake ndi codec ya mawu kuposa codec ya nyimbo.

Kusintha kuchokera ku izo sikungabwezeretse ma frequencies osakhudzidwa — iwo sanali kusinthidwa pamalo oyamba. AMR amawononga nyimbo: yake 8 kHz bandwidth amachotsa zonse pamwamba foni ma frequencies, ndi palibe ndalama ya re-encoding amabweretsa izo kumbuyo.

Ngati AMR ndi lossless ndipo AC3 ndi lossy, yembekezerani kuti codec ya AC3 ibwezeretse; pa 192 kbps izi ndi zosawoneka bwino kwa zinthu zambiri.

Kodi wosintha AMR kupita ku AC3 amasunga ID3 / metadata tags?

Ndikoyenera - dzina, woimba, album, chaka, mndandanda wa nyimbo, album art, ndi masamba olemba (ofunika kwambiri kwa audiobooks) amawerengedwa kuchokera ku AMR ndipo amalemba mu AC3 wokhala ndi AC3 mtundu umathandizira ma tag. M4B audiobook structure round-trips into M4B and AAX → M4B output.

Kodi ndingasinthire mamiliyoni a AMR mafayilo ku AC3?

Yai - chotsani fayilo ya AMR ndikuwapanga mofanana. Premium ili ndi ogwira ntchito ambiri mofanana ndi malire a fayilo, kotero fayilo ya 500-file batch imatha m'maola angapo osati m'maola angapo.

Kodi AC3 idzakhala ndi kuchuluka kwa sampling monga AMR?

Mwachidule ndi yemweyo (48 kHz AMR → 48 kHz AC3). Ngati mukufuna kuchepetsa kusamvana kwa kugwirizana (mwachitsanzo 96 kHz → 44.1 kHz kwa kulemba CD) kusankha kwa kusamvana kwamphamvu kumachita izi ndi kusamvana kwabwino.

Kodi ndingasinthire kuwala kwamphamvu m'njira ya AMR mpaka AC3?

Ndiye — njira yosintha mawu imagwiritsa ntchito ITU-R BS.1770 / EBU R128 yosintha mawu ku AC3, yolenga -14 LUFS (mtengo wosinthira), -16 LUFS (mtengo wosinthira podcast), kapena -23 LUFS (mtengo wosinthira audiobook).

Kodi AC3 idzasewera pafoni yanga yagalimoto / iPod / audiobook app?

MP3 amasewera padziko lonse. AAC amasewera pa Apple, ambiri Android, Sonos. FLAC amasewera pa Sonos ndi Android, osachepera bwino pa zaka zakale iPods. M4B audiobooks kusewera ndi bokosi la navigation pa iOS Buku, Audiobookshelf, ndi Smart Audiobook Player.

Kodi fayilo yanga AMR ndi yapadera panthawi yosintha?

Ndikoyenera - mafayilo a AMR omwe amatulutsidwa amachitidwa m'mabungwe osiyana ndi omwe amagwira ntchito ndipo amachotsa m'maola ochepa. Sitimasewera, sitisunga kapena sitigawana zolemba za audio.

Kodi ndi nthawi yayitali bwanji kuti musinthe audiobook ya 10-hour AMR kupita ku AC3?

Kusinthanso kwa codec yomweyo: 10-30 masekondi. Kusinthanso kwa codec yosiyana: nthawi zambiri 10-20% ya nthawi yoyambira, kotero buku la mawu la maola 10 limatha m'maola 60-120. Mapepala olemba nkhani amapita patsogolo ndi kugawidwa bwinobwino.
