M4A pou AMR FAQ sou Konvèsyon
Ki bitrate ki itilize pa AMR?
+
A lossy AMR 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 AMR (WAV, FLAC) ignores the bitrate and keeps every sample.
Èske mwen pral soti nan M4A pou AMR diminye bon jan kalite son mwen?
+
Si M4A se yon dosye ki gen pèt epi AMR se yon dosye san pèt (egzanp MP3 → WAV), dosye AMR la pa pi bon ke M4A la — ou pa ka rekipere enfòmasyon ki deja pèdi. Si M4A se yon dosye ki pa gen pèt e AMR se yon dosye ki gen pèt, espere ke codec AMR la pral re-kompression; a 192 kbps sa a se transparan pou pifò kontni.
Èske mwen ka konvèti dè santèn de M4A dosye nan AMR?
+
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 AMR a pral kenbe menm vitès echantiyon an tankou M4A?
+
Pa default, se konsa (48 kHz M4A → 48 kHz AMR). Si ou bezwen diminye frekans pou kompatibilite (e. g. 96 kHz → 44.1 kHz pou gravye CD) opsyon avanse pou frekans echantiyon an fè sa ak re-echantiyon kalite wo.
Èske mwen ka normalize loudness nan M4A a AMR etap?
+
Not in this step. The converter has no loudness setting and leaves the level as it is. To even out the volume, run the finished AMR through a Normalize tool on this site.
Èske AMR pral jwe sou stereo machin mwen / iPod / Sonos?
+
MP3 plays almost everywhere. AAC plays on Apple devices, most Android phones and Sonos. FLAC plays on Sonos and Android but not on older iPods, and WAV plays on nearly everything but makes large files. There are no device presets on this page, so choose the target format your player supports.
Èske M4A dosye mwen an prive pandan konvèsyon an?
+
Yes. Uploaded M4A files are processed on our own conversion servers, no person reviews them, and they are never shared. The upload and the converted AMR are both deleted automatically about 24 hours after the conversion, which leaves time to download the result. See /privacy/ for the full policy.
Ki sa ki tan pou konvèti yon 1- èdtan M4A nan AMR?
+
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.
Poukisa AMR dosye a pi fò / pi ba pase M4A sous la?
+
The converter does not change the level: it has no gain or normalize setting. If you hear a difference, your player or media library is probably applying ReplayGain or its own volume levelling on playback; switch that off to hear the AMR as it is.
Èske mwen ka konvèti M4A telechaje streaming nan AMR?
+
Si M4A telechaje a pa pwoteje (pa gen DRM), wi. Fichiers streaming DRM-enkripte (Spotify, Apple Music) yo enkripte nan nivo bit la epi nou pa ka trete yo. Fonksyon yo soti nan Bandcamp, SoundCloud telechaje, ak enskriman pèsonèl yo konvèti byen.
