What is XM?

Extended Module (XM) is the native format of Fast Tracker II, supporting samples, patterns, effects, and volume envelopes.

What is APE?

Monkey's Audio (APE) is a fast, high-performance lossless audio compressor that achieves excellent compression ratios.

When Should You Use XM vs APE?

XM vs APE: Key Differences

• •XM uses lossless compression while APE uses lossless compression — both take the same approach to file size management.
• •Neither format changes compression philosophy — both are lossless compression — so any size differences are due to encoding efficiency, not a shift in quality approach.
• •How transparency is handled: APE supports transparency, so alpha information is preserved during conversion.
• •File sizes: XM files typically range Moderate, depends on sample content and APE files 40-50% smaller than WAV.
• •Primary audience: XM is built for tracker music, demoscene, retro game audio scenarios, while APE focuses on lossless audio archival, audiophile collections — pick the format that matches your output requirement.

Best Practices for XM to APE Conversion

• →For XM to APE: 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
• →APE prioritizes quality — ensure your storage can accommodate the resulting file sizes
• →Check that metadata tags (artist, album, track number) survive the conversion
