About AMR Quality
AMR (Adaptive Multi-Rate) is a speech-optimized, low-bitrate format used by phones and voice recorders — it's small and fine for voice, but not high-fidelity. Converting to MP3 makes those recordings universally playable; since the source is low-bitrate, a modest MP3 bitrate (128–192 kbps) preserves it without wasting space. The MP3 can't sound better than the AMR it came from.
