## New active recordings (October 2026)
* Footsteps on Different Surfaces, compiled/edited by congusbongus: https://opengameart.org/content/footsteps-on-different-surfaces . Concrete, grass and wood by **swuing** (Freesound 38873, 38874, 38876); metal by **Eelke** (462598); tile by **swuing and ceberation** (38873, 235524); water by **EminYILDIRIM and swuing** (608663, 38873). These derivatives are **CC BY 3.0**. Original notices and exact original links are in footstep-licenses/. Gravel by **Ali_6868**, Freesound pack 21608, is **CC0**. RIFT converts to mono, normalizes peaks and fades tails; six variations per surface, five for water.
* Sand footsteps by **Fantozzi**, sliced by **qubodup**, **CC0**: https://opengameart.org/content/fantozzis-footsteps-grasssand-stone . Six recorded steps, normalized/faded/OGG encoded.
* Military helicopter loop by **qubodup**, US Government source, **CC0**: https://freesound.org/people/qubodup/sounds/187681/ . Mono, cropped and crossfaded.
* Launching Anti-Tank Missiles by **qubodup**, US Government source, **CC0**: https://freesound.org/people/qubodup/sounds/184274/ . Final launch cropped separately from blast sounds.
* Explosive and Windy Explosion by **qubodup**, US Government source, **CC0**: https://freesound.org/people/qubodup/sounds/189778/ and https://freesound.org/people/qubodup/sounds/182797/ . Three separate short blast takes plus one long heavy blast; cropped, normalized, tail faded and encoded. Military assets were obtained from the public HQ MP3 previews, not uncompressed studio masters.
* Wind in a Tree by **Joseph SARDIN**, **CC0**: https://bigsoundbank.com/wind-in-a-tree-s0659.html . Recorded outdoor wind/leaves, 36-second crop, mono, normalized and loop crossfaded.
* Beach Ocean Waves by **jasinski**, submitted by **qubodup**, **CC0**: https://opengameart.org/content/beach-ocean-waves . Recorded wave, normalized and loop crossfaded.
refresh-manifest.json records the exact sources, crop offsets, edits, sizes and SHA-256 of the new files. Fifteen gun sound banks each use two individual recorded shots from the full WAV firearm library (single-shot selections, not automatic bursts). Support-gun voicing uses AR-15 recordings; heavy pistol voicing uses Smith & Wesson revolver recordings. Suppressed voicing uses filtered Savage .300 Blackout recordings, not a claimed recording of a suppressed AS VAL. Existing gun takes and retained foley are credited below; recordings.json records the original six gun selections. Weapons share recordings by family, with model-specific pitch/filter/level profiles; these are not recordings of every named weapon model. The runtime uses recorded ambience and combat effects; menu confirmation tones remain synthetic.
## Existing library (CC0)
* **The Free Firearm Sound Library** — Ben Jaszczak, Brian Nelson, Kevin Heras and Matthew Nanney. <https://opengameart.org/content/the-free-firearm-sound-library>. Six individual shots from AR-15, AK-47, Mossberg, 1911, Tikka and PPSh recordings; onset-trimmed, shortened with fade, mono and OGG encoded. Exact originals/offsets are in `recordings.json`. These are weapon-family recordings, not recordings of every fictional weapon.
* **Impact Sounds** — Kenney. <https://kenney.nl/assets/impact-sounds>. Selected concrete, grass and wood footsteps, cloth/body/metal/glass/wood impacts. Original licence notice included as `Kenney-License.txt`.
* **Crows singing** — IgnasD. <https://opengameart.org/content/crows-singing>. `crows.ogg` unchanged.
* **Helicopter SFX** — WuxiaScrub. <https://opengameart.org/content/helicopter-sfx>. Cropped five-second middle section, short edge fades, mono 22.05 kHz OGG. It is an approximation for a rotor loop, not a recording of a particular Huey.
* **Racing car engine sound loops** — domasx2. <https://opengameart.org/content/racing-car-engine-sound-loops>. Public-domain-sample loop_0.wav converted to mono 22.05 kHz OGG. The author's source page documents replacement of an earlier sample with public-domain material.
* **Explosions** — EZduzziteh. <https://opengameart.org/content/explosions-4>. explosion1_0.ogg renamed explosion.ogg.
* **Gun reload sounds** — SpringySpringo. <https://opengameart.org/content/gun-reload-sounds>. Airsoft mechanism recording assaultriflereload1_0.wav converted to mono OGG.
