How to convert AMR to MP3

AMR is a low-bitrate speech codec (4.75-12.2 kbps); converting to MP3 improves compatibility but does not recover audio quality lost at recording time.
For voice recordings, 64-128 kbps MP3 is sufficient - a higher bitrate adds no perceptible improvement.
Files with a .3ga extension (common on Samsung phones) use the same AMR codec and convert to MP3 identically.

Will converting AMR to MP3 improve the sound quality?

No - AMR discards audio detail at recording time and that data is gone. The MP3 will sound the same as the original AMR file.

What bitrate should I choose for the output MP3?

64-128 kbps is enough for AMR voice recordings; anything higher wastes file space without any audible benefit.

My file has a .3ga extension - can I still convert it?

Yes - .3ga files (used by Samsung phones) are AMR recordings in a different wrapper and convert to MP3 the same way.

Can I convert a whole folder of AMR files at once?

Yes, with FFmpeg: on Windows use for %f in (*.amr) do ffmpeg -i "%f" "%~nf.mp3", and on Linux or macOS use a similar shell loop.
