AVI pou AUDIO FAQ sou Konvèsyon
Ki jan mwen ka ekstraksyon sèlman travès la odyo soti nan AVI kòm AUDIO?
+
Upload AVI dosye a ak konvètisè a demuxes kouran odyo a soti nan AVI kontenè a, Lè sa a, transcodes li nan AUDIO. Frames videyo yo te depase - pa gen dezyèm pase videyo, pa gen okenn pèt kalite pi lwen pase sa ki nan AUDIO codec li menm prezante. 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. Audio isit la se yon objektif jeneral: konvètisè a ekstraksyon son an ak chwazi yon enkodaj lajman jwe pou li.
Èske konvèti AVI nan AUDIO se yon dezyèm tou de konpresyon san pèdi tan?
+
Wi, e li vo planifye. De fòma yo se lossy, se konsa AUDIO 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 AUDIO 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. Defaults dezobeyisans dezobeyisans MP3 a 192 kbps, ki se transparan pou pifò materyèl ak lizib pa tout aparèy.
Ki travès son ki sòti lè AVI mwen gen plizyè?
+
One track, picked automatically: normally the main one, the track with the most channels. This page has no setting to choose a different track and does not list the tracks in the file. If you need commentary or a dub instead, remux the AVI with that track first (VLC or ffmpeg can do this) and convert it again.
Ki bitrate ki itilize pa AUDIO?
+
A lossy AUDIO 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 AUDIO (WAV, FLAC) ignores the bitrate and keeps every sample.
Èske mwen pral soti nan AVI a AUDIO diminye bon jan kalite son mwen?
+
Si fòma AUDIO se san pèt (WAV, FLAC, ALAC), tout echantiyon orijinal yo pral konsève. Si AUDIO se san pèt (MP3, AAC, OGG, Opus), codec la pral re-kompression — a 192 kbps diferans lan pa tande pou pifò kontni; a 96 kbps ou ka tande cymbals oswa sibilants mouye. AVI kontenè a pa gen okenn efè sou sa — sèlman paramèt codec la ki enpòtan.
Èske AUDIO ekstraksyon an kenbe AVI vitè echantiyon?
+
Pa default, wi — 48 kHz AVI son vin 48 kHz AUDIO son, 44.1 kHz vin 44.1 kHz. Si ou bezwen fè yon downsampling pou kompatibilite (e. g. 96 kHz studio masters pou 44.1 kHz CD-quality AUDIO) lis drop-down pou frekans-sampling la fè sa ak yon resampling bon kalite.
Èske mwen ka batch-extraire AUDIO son soti nan yon folder nan AVI fichiers?
+
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 li pran pou ekstraksyon AUDIO soti nan yon 1- èdtan AVI?
+
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 AVI mwen an prive pandan ekstraksyon son?
+
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 AUDIO are both deleted automatically about 24 hours after the conversion, which leaves time to download the result. See /privacy/ for the full policy.
Poukisa AUDIO mwen an gen espas silans oswa son ki pa kòrèk?
+
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.
