AIFF i M4A Cwestiynau Cyffredin Trosi

Pa ddidrad mae'r ffeil M4A yn ei ddefnyddio?
+
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.
Os AIFF yw M4A a M4A yw M4A, nid yw'r M4A yn well na'r AIFF — ni allwch adfer gwybodaeth sydd wedi ei thorri'n barod. Os AIFF yw M4A a M4A yw M4A, disgwyliwch i'r M4A codec ail-gywasgu; ar 192 kbps mae hyn yn dryloyw ar gyfer y rhan fwyaf o gynnwys.
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.
Yn rhagosodedig, ie (48 kHz AIFF → 48 kHz M4A). Os oes angen i chi lawr-ddangos am gydnawsedd (e.e. 96 kHz → 44.1 kHz ar gyfer llosgi CD) mae'r dewisiad cyfradd samplu uwch yn gwneud hyn gydag ail-ddangos ansawdd uchel.
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.
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.
Yes. Uploaded AIFF 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.
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.
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 M4A as it is.
Os nad yw'r lawrlwythiad AIFF wedi ei ddiogelu (dim DRM), ie. Mae ffeiliau llif wedi eu cêl-ysgrifo gan DRM (Spotify, Apple Music) wedi eu cêl-ysgrifo ar lefel did ac ni allwn eu prosesu. Mae ffynonellau o Bandcamp, lawrlwythiadau SoundCloud, a recordiadau personol yn cael eu trawsnewid yn dda.

AIFF

Mae AIFF yn cadw sain heb ei gywasgu fel WAV ond mae'n deillio o'r Mac, ac mae'n cario tagiau metadata mwy cyfoethog.

M4A

Mae M4A yn cadw sain AAC mewn cynhwysydd MP4 ac yw'r hyn y mae iTunes a Apple Music yn ei ddefnyddio ar gyfer traciau a lawrlwythwyd.
