AC3 pou AMR FAQ sou Konvèsyon

Ki bitrate ki pral itilize nan AMR dosye a?
+
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.
Wi, e li vo planifye. De fòma yo se lossy, se konsa AMR 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 AMR soti nan sa evite double pass tout antye. AC-3 se yon son multi-kanal ak pèt, nòmalman 5.1 a 384 oswa 448 kbps, ak metadata pou normalizasyon dyalòg ak downmixing. AMR se yon codec pale nan band estrech ki kouri ant 4.75 ak 12.2 kbps, ki modèl la nan traktè vokal imen an plis pase spectre son an antye.
Paske yon bò li se yon codec pale pliske yon codec mizik. Li modèlman anndan chante moun epi li dechèp tout sa ki deyò bandwidth telefòn, ki se byen pou yon memo vwa e destructive pou nenpòt ki bagay ak enstriman nan li. Konvèti lwen li pa ka refè frekans ki manke yo - yo pa janm te enkode nan premye plas la. AC-3 se inefisian pa estanda modèn yo epi li pa aksepte pa navigatè, telefòn oswa pifò jwè entènèt san yon downmix nan stereo.
Si AC3 se lossy epi AMR se lossless (e.g. MP3 → WAV), AMR pa pi bon ke AC3 — ou pa ka rekipere enfòmasyon ki deja pèdi. Si AC3 se lossless epi AMR se lossy, codec AMR re-kompression; a 192 kbps rezilta a se transparan pou pifò kontni.
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.
Pa default, wi — 48 kHz AC3 rete 48 kHz nan AMR. Si ou bezwen fè yon downsampling pou konpatibilite (96 kHz → 44.1 kHz pou gravye CD), opsyon sampling-rate applique yon resampling bon kalite nan menm pase enkodaj la.
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.
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. AMR fè enskri vwa absurdement ti - yon èdtan nan pale ka mete nan kèk megabytes - ak se sa anpil telefòn toujou enskri apèl nan. AMR detwi mizik: bandwidth li a 8 kHz retire tout bagay ki anwo frekans telefòn, epi pa gen okenn kantite re-enkodaj ki pote li tounen.
Yes. Uploaded AC3 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.
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.

AC3

AC3 (Adyo Codec 3) se yon fòma konpresyon odyo ki souvan itilize nan DVD ak Blu-ray disk odyo tren.

AMR

AMR (Adaptive Multi-Rate) se yon fòma konpresyon odyo optimize pou kodaj lapawòl. Li se souvan itilize nan telefòn mobil pou anrejistreman vwa ak lèktur odyo.
