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. AMR shi ne narrowband magana codec aiki tsakanin 4.75 da 12.2 kbps, modeling da mutum vocal tract a matsayin mai cikakken audio spectrum.

By default yes — 48 kHz MOV audio becomes 48 kHz AMR audio, 44.1 kHz becomes 44.1 kHz. If you need to downsample for compatibility (e.g. 96 kHz studio masters to 44.1 kHz CD-quality AMR) the sample-rate dropdown does this with high-quality resampling.

Yes. Uploaded MOV 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.
