Kutsitsa fayilo ya M4A ndi kusinthitsa kwathu kumasankha kulumikizana kwa AC3 codec / bitrate komwe kumagwirizana ndi chiyambi. Kusinthanitsa kopanda malire (AC3 = WAV / FLAC / ALAC) kumateteza chilichonse; kusinthitsa kopanda malire (AC3 = MP3 / AAC / OGG / Opus) kumasinthidwa ku 192 kbps, zomwe ndizosawoneka bwino kwa amayi ambiri.
Kodi fayilo ya AC3 imagwiritsa ntchito bitrate iti?

Ngati M4A ndi lossy ndipo AC3 ndi lossless (mwachitsanzo MP3 -> WAV), fayilo ya AC3 si yabwino kuposa M4A — simungathe kubwezeretsa zambiri zomwe zatulutsidwa kale. Ngati M4A ndi lossless ndipo AC3 ndi lossy, codec ya AC3 imabwezeretsa; pa 192 kbps izi ndi zosawoneka bwino kwa zinthu zambiri.
Ndikofunika - dzina, woimba, album, chaka, mndandanda wa nyimbo, ndi zithunzi za album zimawerengedwa kuchokera ku M4A ndipo zimalemba mu AC3 komwe AC3 imathandizira ma tag (zomwe zimachitika zonse).

Mwa default ndi yeah (48 kHz M4A -> 48 kHz AC3). Ngati mukufuna kuchepetsa khalidwe la kanema chifukwa chogwirizana (mwachitsanzo 96 kHz -> 44.1 kHz polemba CD) mfundo yowonjezera ya khalidwe la kanema imachita izi ndi resampler ya polyphase yopanda malire.
Kodi ndingasinthire kuwala kwa mawu m'mawindo a M4A mpaka AC3?
+
Ndiyo — njira yosintha mawu kuti akhale oyenera imagwiritsa ntchito ITU-R BS.1770 / EBU R128 kuti ikhale yoyenera pa AC3 output, yolenga -14 LUFS (standard yoyenda) kapena -16 LUFS (standard ya podcast).
MP3 amasewera padziko lonse. AAC amasewera pa Apple, ambiri Android, ndi Sonos. FLAC amasewera pa Sonos ndi Android m'madera, otsika bwino pa iPods atsopano. WAV amasewera pa zonse, koma ndi lalikulu. Advanced options kuphatikizapo chipangizo presets kwa izi zofuna zofala.
Kodi fayilo yanga M4A ndi yachikhalidwe panthawi yosintha?
+
Ndiyo — fayilo ya M4A yotulutsidwa imathetsedwa m'maola angapo. Sitimasewera, sitisunga kapena sitigawana zinthu za audio. Onani /privacy/ kuti mudziwe zenera la kusungira deta.
Kodi ndi nthawi yayitali bwanji kuti musinthe nthawi ya 1-hour M4A kuti AC3?

Kusinthanso kwa codec yomweyo: 10-30 masekondi. Kusinthanso kwa codec yosiyana: nthawi zambiri 10-20% ya nthawi yoyambira, kotero 1-hour M4A -> AC3 imatha m'maola 6-12 pa standard pipeline.
Nchifukwa chiyani fayilo ya AC3 ndi yolimba / yolimba kuposa M4A yochokera?
+
Palibe kusintha kwa chitetezo chokhacho chochitika mpaka mutatsegula njira yosintha. Ngati mumaona kusintha kwa chitetezo, wosewera nyimbo kapena laibulale ya ma media akhoza kugwiritsa ntchito ReplayGain kapena kusintha kwa chitetezo cha nyimbo pa kusewera - si ife.
