Understanding FLAC and AIFF Formats

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

Source Format

FLAC Audio

audio/flac

FLAC (Free Lossless Audio Codec) is an open-source lossless audio compression format that typically reduces file sizes by 40-60% compared to uncompressed WAV. It preserves the complete original audio data bit-for-bit, allowing perfect reconstruction of the source. FLAC supports high-resolution audio up to 32-bit depth and 655,350 Hz sample rate with embedded metadata and album art.

Advantages

  • Completely lossless compression preserving bit-perfect audio quality
  • Open-source and royalty-free with broad software and hardware support
  • Typically 40-60% smaller than equivalent WAV files

Limitations

  • Still significantly larger than lossy formats like MP3 or AAC
  • Not supported by all portable devices and car audio systems
  • Encoding and decoding requires more CPU resources than uncompressed formats

Common Uses

  • Audiophile music collections and high-fidelity playback
  • Lossless music archival and library preservation
  • Source format for transcoding to lossy formats for distribution

Target 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
