M4A a WAV Preguntas frecuentes sobre a conversión
Que taxa de bits usa o ficheiro WAV?
+
A lossy WAV 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 WAV (WAV, FLAC) ignores the bitrate and keeps every sample.
Se vou de M4A a WAV, a calidade do son reducirase?
+
Se M4A é con perdas e WAV é sen perdas (por ex. MP3 -> WAV), o ficheiro WAV non é mellor que o M4A — non se pode recuperar información que xa foi descartada. Se M4A é sen perdas e WAV é con perdas, o códec WAV recomprime; a 192 kbps isto é transparente para a maioría do contido.
Podo converter en lote centos de ficheiros M4A a WAV?
+
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.
Podo normalizar o volume no paso M4A a WAV?
+
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 WAV through a Normalize tool on this site.
Reproducirase o WAV no meu estéreo do coche / 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.
O meu ficheiro M4A é privado durante a conversión?
+
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 WAV are both deleted automatically about 24 hours after the conversion, which leaves time to download the result. See /privacy/ for the full policy.
Canto tempo leva converter un M4A de 1 hora en WAV?
+
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.
Por que o ficheiro WAV é máis alto/ máis silencioso que a fonte M4A?
+
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 WAV as it is.
Podo converter as descargas de M4A a WAV?
+
Se a descarga M4A non está protexida (sen DRM), si. Os ficheiros de transmisión cifrados con DRM (Spotify, Apple Music) están cifrados a nivel de bits e non podemos procesalos. As fontes de Bandcamp, SoundCloud e gravacións persoais convértense ben.
