MP4 pou AUDIO FAQ sou Konvèsyon
Ki fòma son mwen pral resevwa nan MP4 mwen an?
+
MP3 pa défaut, paske pa gen anyen refize jwe li. Ou ka chwazi yon lòt objektif: AAC pou pi bon kalite a menm bitrate, FLAC oswa WAV lè ou bezwen lossless, OGG oswa Opus pou fòma louvri ak ba-bitrate pale.
Ki bitrate mwen dwe chwazi?
+
192 kbps is the default and sounds transparent to most listeners on most material. Choose 320 kbps for the highest quality the format offers, or 128 kbps for speech and podcasts, where it is plenty and makes a much smaller file. Going above the source bitrate never adds quality.
Èske mwen ka ekstraye sèlman yon pati nan MP4?
+
Konvèti tout bagay, lè sa a itilize /trim/ sou rezilta a pou kenbe seksyon ou vle. De etap rapid bat re-running yon ekstraksyon long pou ajustman debòde.
Èske MP4 la kenbe plis pase yon chante?
+
If the source carries several tracks (alternate languages, commentary), one is extracted: normally the main one, the track with the most channels. There is no setting to choose a different track, and most audio targets hold a single track anyway.
Ki sa ki sou pousantaj la echantiyon?
+
Fòmil la se presevwa pa default — 44.1 kHz ak 48 kHz tou de pase pa chanje. Re-sampling se disponib men raman itil, depi li pa ka rekipere detay ki pa janm te enskri.
Poukisa dosye son an se pi piti pase MP4?
+
Paske MP4 se pi an sekirite livrezon kontenè: H.264 videyo ak AAC son jwe sou efèktif chak telefòn, navigatè ak TV san yon pake codec — pifò nan bytes orijinal yo te pati ou ap debarase m de. Konserve sèlman travès son an rutinèman pwodwi yon dosye yon ti pati nan gwosè orijinal la, e sa espere, pa yon siy de pèt bon jan kalite.
Èske mwen ka trete plizyè MP4 dosye nan yon fwa?
+
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.
Èske m dwe chwazi yon objektif san pèt?
+
Se sèlman si ou pral edite oubyen masterize son an apre sa. Pou tande, yon bon enkodaj lossy se indiscernable ak yon fraksyon nan gwosè. Remarque ke konvèti yon deja-lossy sous pou yon target lossless pa refè anyen - li jis depo menm son nan yon pi gwo dosye.
Èske MP4 mwen an prive pandan konvèsyon an?
+
Yes. Uploaded MP4 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.
