What is a .SNDA file?

.SNDA is a Marathon (Aleph One) file (Games). Analyser identifies a .SNDA file and reads the metadata in its header, right in your browser.

Did you know
  • Marathon keeps its sound effects in dedicated sound data, separate from its maps and graphics.
  • Marathon was Bungie's breakthrough sci-fi shooter, first released for the Mac in 1994, with a story-rich design ahead of its time.
  • The studio behind Marathon, Bungie, went on to create Halo, and Marathon is often seen as Halo's spiritual ancestor.
What Analyser reads
Identify Marathon (Bungie's 1994 FPS trilogy) and Aleph One data files - the open-source engine that runs Classic Marathon, Marathon 2 and Infinity on Steam: scenario maps (.scen / .sceA), physics models (.phys / .phyA), shapes/sprite collections (.shps / .ShPa), sound collections (.sndz / .sndA), recorded-game films (.filA), interface images (.imgA) and MML config XML (.mml). Reads the big-endian wad header version and the embedded internal name from each.
Depth of analysis
.SNDA is an identification-grade format: Analyser recognises it from its bytes and decodes the header metadata it carries, rather than opening it in a full viewer. Formats that do get a full viewer are marked "Full" on the formats page.
Open a .SNDA file
