AMR: Adaptive Multi-Rate codec. Common for voice recordings. MP3: The most common audio format. Lossy compression, universal support. Converting from AMR to MP3 is useful when you need the specific advantages of the MP3 format — whether that's compatibility, file size, quality, or feature support.
The converter decodes your AMR audio data and re-encodes it in MP3 format. Audio quality depends on the target format: lossless formats (WAV, FLAC) preserve full quality, while lossy formats (MP3, OGG) compress the audio to reduce file size.
