AVI pou AAC FAQ sou Konvèsyon
Ki jan mwen ka ekstrè son an soti nan dosye AVI mwen an kòm AAC?
+
Upload AVI dosye a ak konvètisè a demuxes kouran son an, Lè sa a, transcodes li nan AAC. Pa gen okenn dezyèm pase videyo - track vizyèl la se dechèpman imedyatman konsa ekstraksyon an se anpil pi vit pase yon re-encode konplè. AVI se Audio Video Interleave Microsoft, ki te prezante nan 1992 sou tèt la RIFF fòma chunk - youn nan pi ansyen kontenè toujou nan circulation. AAC se yon mo angle ki vle di Advanced Audio Coding, yon fòma ki te etabli an 1997 kòm MPEG-2 Part 7.
Èske konvèti AVI nan AAC se yon dezyèm tou de konpresyon san pèdi tan?
+
Wi, e li vo planifye. De fòma yo se lossy, se konsa AAC encoder travay soti nan son ki te deja pase pa yon pass psychoacoustic, ak li tèt li desizyon yo konpoze premye set. A 192 kbps oswa pi wo a rezilta a se toujou transparan pou pifò tande. Si ou gen yon master lossless nenpòt kote, enkodaj AAC soti nan sa evite double pass tout antye. AVI fichiers pre-codecs modèn: espere MPEG-4 pati 2 (DivX/Xvid), Motion JPEG oswa framework raw uncompressed piske H.264. AAC se yon fòma ki gen anpil pèt men ki pi efikas pase MP3, epi li ka kontwole jiska 48 chanèl natif natalman olye pou yo dwe boulon sou yon estèyo konsepsyon.
Ki bitrate son ki itilize pa AAC ki te ekstraye a?
+
A lossy AAC is encoded at 192 kbps by default. The Audio Quality setting also offers 320 kbps for the best quality and 128 kbps for a smaller file. A lossless AAC (WAV, FLAC) ignores the bitrate and keeps every sample.
Èske mwen pral pèdi bon jan kalite son an lè m ap soti nan AVI pou AAC?
+
Si AAC se san pèt (WAV, FLAC), chak echantiyon an pral presevwa egzakteman. Si AAC se ak pèt (MP3, AAC, OGG, Opus), codec AAC re-kompression l'audio sous - a 192 kbps rezilta a se transparan pou prèske tout kontni. Going lossy → lossless pa janm rekipere detay ki deja defason.
Èske mwen ka ekstrè son an soti nan plizyè AVI dosye nan AAC nan yon sèl batch?
+
Several files in one job need a paid plan. Free use is one file per conversion, one conversion an hour. On a paid plan you can add several files to one job, then download each result on its own or all of them in one ZIP.
Ki sa ki tan pou ekstraksyon AAC son soti nan yon 1-èdtan AVI pran?
+
It depends on the size and length of the file. Small documents and images are usually ready quickly. Long videos take the longest, because most video conversions re-encode every frame.
Èske mwen ka ekstrè sèlman yon pati nan AVI son an kòm AAC?
+
Pa nan zouti sa a dirèkteman — ekstrè son an antye kòm AAC, Lè sa a itilize /audio-trim/ oswa /audio-cutter/ pou koupe seksyon an. Path la de etap se nòmalman pi vit pase yon operasyon konbine epi li bay ou kontwòl presizyon waveform-nivo.
Èske AVI dosye mwen prive pandan ekstraksyon son an?
+
Yes. Uploaded AVI files are processed on our own conversion servers, no person reviews them, and they are never shared. The upload and the converted AAC are both deleted automatically about 24 hours after the conversion, which leaves time to download the result. See /privacy/ for the full policy.
Poukisa dosye AAC gen espas silendrik kote AVI te gen son?
+
Usually the AVI carries more than one audio track and the one that was converted is silent or secondary. The converter picks one audio track automatically, normally the main one, and this page has no setting to choose a different track. If the wrong one comes out, remux the AVI with the track you want first (VLC or ffmpeg can do this) and convert it again.
