What is XM?

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

What is DSF?

DSF files are built around lossless compression. Designed for dsd music playback, high-end audio systems, they use the audio/x-dsf MIME type and typically range from varies by content.

When Should You Use XM vs DSF?

XM vs DSF: Key Differences

• •XM and DSF diverge on compression: lossless compression for the source, lossless compression for the target.
• •Since both XM and DSF use lossless compression, the quality characteristics are comparable — differences in file size come down to how efficiently each format implements compression.
• •Alpha channel support: DSF handles transparency.
• •DSF files tend to be differently sized than XM
• •XM is optimized for tracker music, demoscene, retro game audio while DSF is designed for dsd music playback, high-end audio systems — choose based on your specific workflow needs

Advantages of DSF

• ✓The lossless nature of DSF means file sizes stay reasonable while handling DSD music playback, high-end audio systems efficiently.
• ✓From mobile devices to enterprise servers, DSF is recognized and supported everywhere.
• ✓The trade-off for DSF's perfection is larger files — but for archival work, it is worth every megabyte.

Troubleshooting XM to DSF Conversion

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