Understanding AIFF and AMR Formats

Learn about the source and target file formats to understand what happens during conversion.

Source Format

AIFF Audio

audio/aiff

AIFF (Audio Interchange File Format) is an uncompressed audio format developed by Apple, based on the IFF (Interchange File Format) structure. Like WAV, it stores raw PCM audio data at full quality, but uses big-endian byte ordering. AIFF is the standard uncompressed audio format in macOS and professional audio production on Apple platforms.

Advantages

  • Completely lossless with full PCM audio quality
  • Native support in macOS and all Apple audio software
  • Supports embedded metadata including loop points for music production

Limitations

  • Very large file sizes comparable to WAV
  • Less universal than WAV on non-Apple platforms
  • Not suitable for portable use or streaming due to file size

Common Uses

  • Professional audio production on macOS
  • Apple ecosystem audio recording and editing
  • Music production sample libraries and loop files

Target Format

AMR Audio

audio/amr

AMR (Adaptive Multi-Rate) is a compressed audio format optimized specifically for speech encoding, widely used in mobile telecommunications. It employs adaptive bitrate encoding that adjusts between 4.75 and 12.2 kbps based on network conditions, prioritizing speech intelligibility over music quality. AMR is the standard speech codec for GSM and UMTS mobile networks worldwide.

Advantages

  • Extremely small file sizes optimized for voice content
  • Adaptive bitrate adjusts to network conditions in real-time
  • Standard codec in GSM/3G mobile networks worldwide

Limitations

  • Very poor quality for music or non-speech audio
  • Limited to narrowband (8 kHz) or wideband (16 kHz) sampling
  • Not suitable for high-fidelity audio or media production

Common Uses

  • Mobile phone voice recording and voice memos
  • Cellular voice call encoding in GSM/3G networks
  • MMS voice message attachments
