Why convert AMR to MP3?
AMR is a mobile voice codec used by older Android and feature phones for call recordings and MMS voice notes. Most media players, editors, and sharing platforms do not accept AMR, so converting to .MP3 makes the file universally playable. The conversion changes the container and codec but cannot recover audio detail that AMR discarded at recording time.

- 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
.3gaextension (common on Samsung phones) use the same AMR codec and convert to MP3 identically.
