FLV → MP3

Wi, e li vo planifye. De fòma yo se lossy, se konsa MP3 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 MP3 soti nan sa evite double pass tout antye. FLV gen depoze Sorenson Spark oswa H.264 videyo ak MP3 oswa AAC son, enpak nan yon fòma stream ki fèt pou RTMP livrezon. MP3 se yon fòma ki gen anpil pèt: yon modèl psikoacoustic depase frekans ki pa ka rekonèt pa zòrèy la, anjeneral nan 128 a 320 kbps.

A lossy MP3 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 MP3 (WAV, FLAC) ignores the bitrate and keeps every sample.

Si MP3 se san pèt (WAV, FLAC), chak echantiyon an pral presevwa egzakteman. Si MP3 se ak pèt (MP3, AAC, OGG, Opus), codec MP3 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.

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.

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.

Pa nan zouti sa a dirèkteman — ekstrè son an antye kòm MP3, 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.

Yes. Uploaded FLV files are processed on our own conversion servers, no person reviews them, and they are never shared. The upload and the converted MP3 are both deleted automatically about 24 hours after the conversion, which leaves time to download the result. See /privacy/ for the full policy.

Usually the FLV 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 FLV with the track you want first (VLC or ffmpeg can do this) and convert it again.
