What is XM?

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

What is 3GA?

3GA files are built around lossy compression. Designed for mobile voice recordings, phone memos, they use the audio/3gpp MIME type and typically range from varies by content.

When Should You Use XM vs 3GA?

XM vs 3GA: Key Differences

• •The core technical difference: XM relies on lossless compression whereas 3GA uses lossy compression.
• •The switch from lossless compression to lossy compression means you gain significant space savings while accepting minor quality trade-offs.
• •How transparency is handled: 3GA does not support alpha channels — transparent areas in the source will become opaque.
• •Storage footprint: Moderate, depends on sample content for XM vs varies for 3GA.
• •XM is optimized for tracker music, demoscene, retro game audio while 3GA is designed for mobile voice recordings, phone memos — choose based on your specific workflow needs

Troubleshooting XM to 3GA Conversion

• !Clicks or pops in the converted 3GA → sample rate conversion can introduce artifacts; use a clean multiple of the source rate
• !3GA 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 3GA → verify that the converter preserves channel mapping for multichannel audio
• !The converted 3GA clips or distorts at peaks → reduce the gain or apply a limiter before conversion to prevent hard clipping
