Not in this viewer. There is no working JavaScript playback library for these formats that runs reliably across modern browsers. We surface metadata — title, sample names, channels, patterns — and recommend OpenMPT desktop or ffmpeg + libopenmpt for audio playback.

Which tracker formats does it detect?

Impulse Tracker (IT, magic 'IMPM'), FastTracker II XM ('Extended Module: ' header), ScreamTracker 3 (S3M, 'SCRM' at offset 0x2C), and ProTracker MOD (4-char signature at offset 1080 — M.K., M!K!, FLT4, 8CHN, etc).

Where do the sample names come from?

Each format stores them in a fixed position: MOD has 31 samples at offsets 20, 50, 80, …; IT samples have an 'IMPS' marker followed by a 26-byte name; S3M has paragraph-indexed sample headers. XM stores samples inside instrument blocks which are too deeply nested to enumerate without unpacking patterns.

About MOD / IT / XM / S3M

Tracker modules — header and sample listing.

Tracker modules are pattern-based songs that pack samples plus per-channel event grids into a single file — born on the Amiga, polished in the demoscene. There's no maintained JavaScript playback library that runs reliably in modern browsers (libopenmpt's official WASM build is a moving target and chiptune2.js is unmaintained), so this viewer surfaces the module's title, signature, channel count, pattern count, and sample list. To listen, convert to MP3/OGG with ffmpeg or open the file in OpenMPT desktop.
