AMR i AC3 Cwestiynau Cyffredin Trosi

Pa ddidrad mae'r ffeil AC3 yn ei ddefnyddio?

A lossy AC3 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 AC3 (WAV, FLAC) ignores the bitrate and keeps every sample.

A fydd mynd o AMR i AC3 yn lleihau fy ansawdd sain?

Os AMR yw â cholli a AC3 yw heb golli (e.e. MP3 → WAV), nid yw'r ffeil AC3 yn well na'r ffynhonnell AMR — ni allwch adfer gwybodaeth a gollwyd gan yr amgodiad gwreiddiol â cholli. Os yw AMR yn heb golli a AC3 yn heb golli, disgwyliwch i'r codec AC3 ail-gywasgu; wrth 192 kbps mae hyn yn dryloyw ar gyfer bron pob deunydd.

A allaf drosi cannoedd o AMR ffeiliau i AC3?

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.

A allaf normaleiddio'r lefel sain yn y cam AMR i AC3?

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 AC3 through a Normalize tool on this site.

A fydd y AC3 yn chwarae ar fy stereo car, iPod, neu 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.

A yw fy AMR ffeil yn breifat wrth drosi?

Yes. Uploaded AMR files are processed on our own conversion servers, no person reviews them, and they are never shared. The upload and the converted AC3 are both deleted automatically about 24 hours after the conversion, which leaves time to download the result. See /privacy/ for the full policy.

Faint o amser mae trosi AMR 1 awr i AC3 yn ei gymryd?

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.

Pam mae'r ffeil AC3 yn uwch neu'n is na'r ffynhonnell AMR?

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 AC3 as it is.

A allaf drosi AMR o lawrlwythiadau llif i AC3?

Os nad yw'r AMR lawrlwythiad wedi'i ddiogelu (dim DRM), ie. Mae ffeiliau llif wedi'u cêl-ysgrifo gan DRM (Spotify all-lein, Apple Music) wedi'u cêl-ysgrifo ar lefel beitiau ac ni allwn eu datgryptio na'u prosesu. Trosglwyddir ffynonellau o Bandcamp, SoundCloud, archive.org, a recordiadau personol heb broblem.

AMR

Mae AMR (Adaptive Multi-Rate) yn fformat cywasgu sain sydd wedi'i optimeiddio ar gyfer codio lleferydd. Fe'i defnyddir yn gyffredin mewn ffonau symudol ar gyfer recordiadau llais a chwarae sain.
