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.

What is MOD?

Protracker Module (MOD) is a tracker music format originating from the Amiga demoscene, containing both note patterns and instrument samples.

When Should You Use CAF vs MOD?

CAF vs MOD: Key Differences

• •CAF and MOD 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
• •File sizes: CAF files typically range Flexible, supports very large files and MOD files Small with size proportional to samples.
• •CAF is optimized for apple audio production, professional editing while MOD is designed for chiptune music, demoscene, retro game audio — choose based on your specific workflow needs

Advantages of CAF

• ✓CAF applies lossless compression specifically calibrated for Apple audio production, professional editing.
• ✓CAF enjoys broad native support across operating systems, browsers, and creative tools alike.
• ✓CAF guarantees every bit of the original data survives — no approximations, no shortcuts.
• ✓You will find CAF support built into virtually every tool that handles Apple audio production, professional editing — no plugins or converters needed.

Advantages of MOD

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

Common Use Cases for CAF to MOD Conversion

• Streaming services
• Audio books
• Sound design

Troubleshooting CAF to MOD Conversion

• !Clicks or pops in the converted MOD → sample rate conversion can introduce artifacts; use a clean multiple of the source rate
• !MOD file has silence at the beginning or end → trim the source CAF file before converting to avoid unnecessary padding
• !Stereo image collapsed after converting CAF to MOD → verify that the converter preserves channel mapping for multichannel audio
• !The converted MOD clips or distorts at peaks → reduce the gain or apply a limiter before conversion to prevent hard clipping
