RELOAD HANDLING (reload-start.wav)
Gun reload sounds / assaultriflereload1.wav by SpringySpringo, CC0.

https://creativecommons.org/publicdomain/zero/1.0/
Recorded using an airsoft gun. The runtime sample contains only initial handling.
MODIFICATIONS
Selected six mastered footstep variants per surface and three isolated SKS shots;
converted to mono PCM 16-bit WAV, 44.1 kHz; trimmed leading silence; applied a
65 Hz high-pass, normalized loudness with peak headroom and faded sample ends.
The concrete variations come from one original recorded step, not six new takes.
The game applies spatial panning, distance, occlusion and movement gain at runtime.
None of these sounds or their timing decides damage, ammunition or reload state.
Creators have not endorsed this project. No paid resources or private demos used.
Source recordings, archive/license evidence, hashes and the reproducible edit tool
are tracked in assets/sources/audio/, assets/manifests/recorded-audio.json and
tools/prepare-recorded-audio.mjs in the project repository.
