M4A chun AMR Ceisteanna Coitianta maidir le Comhshó
Cén giotánráta a úsáideann an comhad 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.
An laghdóidh mé mo cháilíocht fuaime ó M4A go AMR?
+
Má tá M4A caillteach agus AMR gan chaillteanas (m. sh. MP3 → WAV), níl an comhad AMR níos fearr ná an M4A — ní féidir leat faisnéis a caitheadh amach cheana a aisghabháil. Má tá M4A caillteach agus AMR gan chaillteanas, bí ag súil go ndéanfaidh an AMR cód ath- chomhbhrú; ag 192 kbps tá sé seo trédhearcach don chuid is mó den ábhar.
An féidir liom na céadta M4A comhad a thiontú go 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.
An gcoimeádfaidh an AMR an ráta samplach céanna le M4A?
+
Réamhshocrú: tá (48 kHz M4A → 48 kHz AMR). Más gá duit íossampláil le haghaidh comhoiriúnachta (m. sh. 96 kHz → 44. 1 kHz le haghaidh dlúthdhiosca a dhó) déanann an rogha ardráta samplála é seo le hathshampláil ardcháilíochta.
An féidir liom an t-airde a normalú sa chéim M4A go AMR?
+
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.
An mbeidh an AMR ag imirt ar mo steirió carr / 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.
An bhfuil mo M4A comhad príobháideach le linn comhshó?
+
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.
Cé chomh fada is a thógann sé 1 uair an chloig M4A a thiontú go 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.
Cén fáth go bhfuil an comhad AMR níos airde / níos ciúine ná an fhoinse 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 AMR as it is.
An féidir liom M4A íoslódálacha sruthú a thiontú go AMR?
+
Má tá an M4A íoslódáil gan chosaint (gan DRM), tá. Tá comhaid sruthú criptithe DRM (Spotify, Apple Music) criptithe ag leibhéal na giotán agus ní féidir linn iad a phróiseáil. Foinsí ó Bandcamp, íoslódáil SoundCloud, agus taifeadtaí pearsanta a thiontú go breá.
