What audio bitrate does the extracted AMR use?

Default bitrate for lossy AMR is 192 kbps, which is transparent for music. You can override to 320 kbps (audiophile) or 96-128 kbps (voice / podcast / smaller file). The bitrate dropdown is exposed in the advanced options before you click convert.

Ńwò ní mò lè pa ìṣàfarawé ìṣàmúlò-ètò láti inú MP4 sí AMR?

If AMR is lossless (WAV, FLAC), every sample is preserved exactly. If AMR is lossy (MP3, AAC, OGG, Opus), the AMR codec recompresses the source audio — at 192 kbps the result is transparent for almost all content. Going lossy → lossless never recovers detail already discarded.

Audio demux + encode is fast — typically 5 to 15% of the source duration. A 1-hour MP4 → AMR finishes in roughly 3 to 9 minutes on the standard pipeline; Premium parallelism cuts this further for batch jobs.

Almost always a wrong-stream selection: MP4 had multiple audio tracks and the demuxer picked an empty or auxiliary stream. Use the advanced "audio stream" picker to select stream 0, 1, 2 explicitly, or target a AMR container that supports multi-track output (FLAC, OGG).

Ń lè fi AMR pamọ́ láti inú stereo, mono, tàbí 5.1 surround?

Channel layout is preserved from MP4 by default — a 5.1 MP4 produces a 5.1 AMR if the AMR codec supports it (AAC, FLAC, OGG, Opus). The downmix option forces stereo or mono — useful for podcast workflows where surround tracks waste bitrate.

MP3 plays everywhere with zero compatibility risk. AAC plays on Apple, most Android, and Sonos. OGG / Opus needs a recent player on iOS. The advanced device-preset dropdown picks the AMR codec most likely to play on your target hardware.
