What is IFF?

Interchange File Format (IFF) is the Amiga multimedia container format used for audio, images, and 3D data on Commodore systems.

What is CAF?

Core Audio Format (CAF) is Apple's audio container designed to overcome the file size and sample rate limitations of AIFF and WAV.

When Should You Use IFF vs CAF?

IFF vs CAF: Key Differences

• •IFF and CAF diverge on compression: lossless compression for the source, lossless compression for the target.
• •Both formats share lossless compression, so quality behavior is similar across the two — file size differences come from algorithm efficiency rather than compression philosophy.
• •Transparency: N/A
• •Storage footprint: Varies by content type for IFF vs Flexible, supports very large files for CAF.
• •Use case fit: IFF targets amiga audio, legacy multimedia, mod music and CAF targets apple audio production, professional editing — your choice depends on which workflow stage you are serving.

Advantages of IFF

• ✓The lossless nature of IFF means file sizes stay reasonable while handling Amiga audio, legacy multimedia, MOD music efficiently.
• ✓From mobile devices to enterprise servers, IFF is recognized and supported everywhere.
• ✓The trade-off for IFF's perfection is larger files — but for archival work, it is worth every megabyte.
• ✓IFF is a first-class citizen in all major software ecosystems, from creative suites to development environments.

Advantages of CAF

• ✓CAF compresses data using lossless methods, keeping file sizes manageable for Apple audio production, professional editing.
• ✓Industry-wide support means CAF files open anywhere — from legacy systems to the latest devices.
• ✓Lossless quality makes CAF the gold standard for archival and master copies.
• ✓From professional software to open-source alternatives, CAF works out of the box.

Common Use Cases for IFF to CAF Conversion

• Audiovisual installation
• Music education
• Conference call recordings
• Field recording preservation
• Music production and mixing
• Podcast distribution

Industry Applications

Best Practices for IFF to CAF Conversion

• →For IFF to CAF: match the sample rate and bit depth to your delivery platform — 44.1 kHz / 16-bit is the standard for music
• →Apply loudness normalization (LUFS) before conversion to ensure consistent volume across your audio library
• →CAF prioritizes quality — ensure your storage can accommodate the resulting file sizes
• →Check that metadata tags (artist, album, track number) survive the conversion
• →Convert a short segment first to verify quality at your chosen bitrate
• →Keep a lossless master copy in case you need to re-encode for a different platform

Troubleshooting IFF to CAF Conversion

• !CAF audio quality degraded vs IFF → use a higher bitrate (at least 256 kbps for music)
• !CAF file won't play on your device → check format compatibility with your player or platform
• !Metadata (artist, album, title) lost after IFF to CAF conversion → some formats like CAF may not support ID3 tags
• !Volume changed after converting IFF to CAF → normalize audio levels before conversion for consistent playback
