MP3 pou M4R FAQ sou Konvèsyon
Ki bitrate ki pral itilize nan M4R dosye a?
+
A lossy M4R 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 M4R (WAV, FLAC) ignores the bitrate and keeps every sample.
Èske konvèti MP3 nan M4R se yon dezyèm tou de konpresyon san pèdi tan?
+
Wi, e li vo planifye. De fòma yo se lossy, se konsa M4R 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 M4R soti nan sa evite double pass tout antye. 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. Payload la se AAC, konvensyonèlman limite a 40 segonn, ki se pi long ton iOS pral aksepte.
Èske ale soti nan MP3 a M4R pral diminye bon jan kalite son mwen an?
+
Si MP3 se lossy epi M4R se lossless (e.g. MP3 → WAV), M4R pa pi bon ke MP3 — ou pa ka rekipere enfòmasyon ki deja pèdi. Si MP3 se lossless epi M4R se lossy, codec M4R re-kompression; a 192 kbps rezilta a se transparan pou pifò kontni.
Èske mwen ka konvèti dè santèn de MP3 dosye nan M4R?
+
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 M4R ap kenbe menm kantite vòt tankou MP3?
+
Pa default, wi — 48 kHz MP3 rete 48 kHz nan M4R. Si ou bezwen fè yon downsampling pou konpatibilite (96 kHz → 44.1 kHz pou gravye CD), opsyon sampling-rate applique yon resampling bon kalite nan menm pase enkodaj la.
Èske mwen ka normalize loudness lè mwen konvèti MP3 nan M4R?
+
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 M4R through a Normalize tool on this site.
Èske M4R mwen pral jwe sou stereo machin, iPod, ak 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. M4R tonbe dwat nan lis son iOS via Finder oswa iTunes san okenn lòt pwosesis. M4R se Apple-se sèlman ak longè limite; nenpòt ki bagay sou 40 segonn se san bri refize pa telefòn lan.
Èske MP3 dosye mwen prive pandan konvèsyon an nan M4R?
+
Yes. Uploaded MP3 files are processed on our own conversion servers, no person reviews them, and they are never shared. The upload and the converted M4R 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 MP3 nan M4R?
+
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 M4R pi fò oswa pi ba pase sous MP3?
+
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 M4R as it is.
