Why convert AMR to MP3?
MP3 may be better supported by your device or app. To keep quality, choose a bitrate equal to or higher than the original AMR.
MP3 is best for music libraries, sharing, podcasts and playback on any device. Plays on virtually every phone, computer, car stereo, browser and media player.
Will I lose quality?
Converting between two lossy formats re-encodes the audio, which can add a small amount of loss. Use a bitrate at least as high as the original (192 kbps or more) to keep it transparent.
