+
Mwa default ndi yeah (48 kHz AC3 -> 48 kHz AMR). 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 AC3 mpaka AMR?
+
Ndiyo — njira yosintha mawu kuti akhale oyenera imagwiritsa ntchito ITU-R BS.1770 / EBU R128 kuti ikhale yoyenera pa AMR output, yolenga -14 LUFS (standard yoyenda) kapena -16 LUFS (standard ya podcast).
Kodi AMR idzasewera pa stereo yagalimoto yanga / iPod / Sonos?
+
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 AC3 ndi yachikhalidwe panthawi yosintha?
+
Ndiyo — fayilo ya AC3 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 AC3 kuti AMR?
+
Kusinthanso kwa codec yomweyo: 10-30 masekondi. Kusinthanso kwa codec yosiyana: nthawi zambiri 10-20% ya nthawi yoyambira, kotero 1-hour AC3 -> AMR imatha m'maola 6-12 pa standard pipeline.
Nchifukwa chiyani fayilo ya AMR ndi yolimba / yolimba kuposa AC3 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.
