Mafomu awiriwa ndi owonongeka, choncho AMR 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 AMR kuchokera ku yomwe imalepheretsa kupitanso koyamba. A MOV nthawi zambiri amatenga H.264 kapena HEVC kwa kutumiza, kapena ProRes pamene ndi kusintha mtsogoleri, limodzi ndi AAC kapena uncompressed PCM audio. AMR ndi narrowband mawu codec kuyendetsa pakati pa 4.75 ndi 12.2 kbps, modeling munthu woimba m'mimba kuposa wonse audio spectrum.

N’chifukwa chiyani nyimbo zimawoneka zoipa kwambiri pa chikhulupiriro?

Chifukwa chimodzi mwazigawo zake ndi codec ya mawu kuposa codec ya nyimbo. Imakhala ndi maonekedwe a munthu woimba ndipo imachotsa chilichonse m’mbali mwa bandwidth ya foni, chomwe ndi choyenera kwa mawu olemba mawu komanso chowononga kwa chilichonse chomwe chili ndi zida.

Mwa default yes — 48 kHz MOV audio imakhala 48 kHz AMR 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 AMR) mndandanda wolowetsa wa sampling-rate amachita izi ndi kusamvana kwabwino.

Kodi ndingagwiritse ntchito AMR audio kuchokera ku fayilo ya MOV?

Mavidiyo ambiri m'modzi ntchito ayenera kulipira ndondomeko. Free kugwiritsa ntchito ndi imodzi wapamwamba pa kusintha, imodzi kusintha pa ola. Pa ndondomeko yolipira mukhoza kuwonjezera angapo owona kuti ntchito imodzi, ndiye download zotsatira zonse pamodzi kapena onse awo mu ZIP imodzi.

Kodi ndi nthawi yayitali bwanji kuti mutenge AMR kuchokera ku 1-hour MOV?
