When Should You Use XM vs AIFF?

XM vs AIFF: Key Differences

• •XM and AIFF diverge on compression: lossless compression for the source, lossless compression for the target.
• •Since both XM and AIFF use lossless compression, the quality characteristics are comparable — differences in file size come down to how efficiently each format implements compression.
• •Transparency: N/A
• •Storage footprint: Moderate, depends on sample content for XM vs 10MB per minute at CD quality for AIFF.
• •Primary audience: XM is built for tracker music, demoscene, retro game audio scenarios, while AIFF focuses on professional audio production, music recording — pick the format that matches your output requirement.
