WMA pou M4A FAQ sou Konvèsyon
Ki bitrate ki pral itilize nan M4A dosye a?
+
A lossy M4A 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 M4A (WAV, FLAC) ignores the bitrate and keeps every sample.
Èske konvèti WMA nan M4A se yon dezyèm tou de konpresyon san pèdi tan?
+
Wi, e li vo planifye. De fòma yo se lossy, se konsa M4A 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 M4A soti nan sa evite double pass tout antye. WMA se lossy pa default, nan yon ASF kontenè, ak varyasyon lossless ak vwa-optimise ki raman te rankontre. An M4A kenbe AAC nan pifò ka, oswa Apple Lossless (ALAC) lè li te soti nan yon rip lossless.
Poukisa kèk nan WMA dosye mwen yo pa pral konvèti?
+
DRM. Yon pati nan WMA dosye yo enkripte pa magazen an oswa lojisyèl ki te bay yo, ak son enkripte pa ka dekode pa nenpòt ki konvètisè. Nenpòt bagay ou te ripped tèt ou, enskri, oswa achte san pwoteksyon konvèti nòmalman; yon achte lisans pa pral. WMA se pa sipòte prèske nenpòt kote deyò Windows, ak fichiers WMA pi gran ka pote DRM ki bloke konvèsyon an tout antye.
Èske mwen pral soti nan WMA a M4A diminye bon jan kalite son mwen?
+
Si WMA se lossy epi M4A se lossless (egzanp MP3 → WAV), M4A pa pi bon ke WMA — ou pa ka rekipere enfòmasyon ki deja pèdi. Si WMA se lossless epi M4A se lossy, M4A codec re-kompression; a 192 kbps rezilta a se transparan pou pifò kontni.
Èske mwen ka konvèti dè santèn de WMA dosye nan M4A?
+
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 M4A a pral kenbe menm vitès echantiyon an tankou WMA?
+
Pa default, wi — 48 kHz WMA rete 48 kHz nan M4A. Si ou bezwen diminye kantite echantiyon pou kompatibilite (96 kHz → 44.1 kHz pou gravye CD), opsyon kantite echantiyon ap aplike re-echantiyon kalite segondè nan menm pase enkodaj la.
Èske mwen ka normalize loudness lè mwen konvèti WMA nan M4A?
+
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 M4A through a Normalize tool on this site.
Èske M4A 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. M4A kenbe rich iTunes-estil metadata, chapit ak artwork intact, ak se natif natal audio format sou tout aparèy Apple. M4A kache de bagay ki diferan dèyè yon ekstansyon — lossy AAC ak lossless ALAC — ak non-Apple sipò pou hardware se incohérent.
Èske WMA dosye mwen prive pandan konvèsyon an nan M4A?
+
Yes. Uploaded WMA files are processed on our own conversion servers, no person reviews them, and they are never shared. The upload and the converted M4A 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 li pran pou konvèti yon 1-èdtan WMA nan M4A?
+
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.
M4A se yon fòma dosye odyo ki gen rapò ak MP4. Li ofri konpresyon odyo-wo kalite ak sipò pou metadata, fè li apwopriye pou aplikasyon pou divès kalite.
