How to convert 3GP to MP3

AMR audio from older phones re-encodes to MP3 at 8 kHz speech quality - choosing a higher bitrate does not improve it.
If the original 3gp carried AAC audio, the MP3 output will sound noticeably cleaner and a bitrate of 128 kbps or above is worthwhile.
The source 3gp is unchanged; only the exported mp3 lacks the video track.

Will converting 3GP to MP3 improve the audio quality?

No. Re-encoding AMR to MP3 cannot recover quality lost when the phone originally recorded in AMR - the MP3 will sound identical to the source.

My 3GP file has no sound - will converting fix it?

Unlikely. Open the file in VLC first; if VLC is also silent the file has no audio track, and converting will produce a silent mp3.

What MP3 bitrate should I pick?

For AMR speech recordings 96-128 kbps is plenty; for AAC music recordings 192 kbps or higher is reasonable.

Does this work for `.3g2` files too?

Yes - 3g2 uses the same container structure as 3gp and all the tools listed here handle both formats identically.
