RELOAD HANDLING (reload-start.wav) Gun reload sounds / assaultriflereload1.wav by SpringySpringo, CC0. https://opengameart.org/content/gun-reload-sounds 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. ROUND 2 SOUNDS (r2/*.wav) Prepared 2026-09-23 by Claude Code (lane I) for Adrian / Siantek with tools/prepare-sfx.mjs; per-file provenance in assets/manifests/sfx-r2.json. Gunshots (r2/shot-*, r2/far-*, r2/tail-*): The Free Firearm Sound Library (Prepared SFX Library) by Ben Jaszczak, Brian Nelson, Kevin Heras and Matthew Nanney, CC0. Recordings of real firearms stand in for the fictional weapons: AR-15 (C1), Walther PPQ (P9), Mosin Nagant (S5), Carl Gustav M45 (Q2), AK-47 (N4), Benelli Nova (B6), Tikka T3 (D7), Colt 1911 (H3). https://opengameart.org/content/the-free-firearm-sound-library Far layers, suppressed shots and indoor tails are processed from these recordings (filters, echoes, a synthetic room); they are not separate recordings. Round 5: the near reports carry a synthesized sine thump, parallel compression and soft saturation; the far layers roll through five darkening echoes; the rifle burst tail (r2/tail-burst-rifle.wav) is the AK-47's long burst at mid distance (C_36P) after its last round. ROUND 5 REDONE SOUNDS (2026-09-24, lane 5c, Adrian's picks) All CC0, from Freesound HQ previews (hashes and page snapshots in assets/sources/audio/r2/license-evidence/freesound-<id>.html.txt).

GENERATED SOUNDS (ai/grenade-*.wav) The frag (near and far), smoke pop and flashbang, generated with ElevenLabs sound effects (eleven_text_to_sound_v2) on Adrian Garcia's (owner) personal ElevenLabs account, 2026-09-24; prompts, selection, cutting and levels by Claude Code (lane A) for Adrian / Siantek with tools/prepare-sfx-ai.mjs --build. Per-file prompt, date, account and processing in assets/manifests/sfx-ai.json. They replace the synthesized grenade sounds, which remain the fallback while the set loads. The generated footsteps, gunshots, flybys, gear and movement sounds were withdrawn (Adrian, 2026-09-23). The flyby crack, the heavy landing, the vault and prone sounds, the impact snap, the pin and bounces, the smoke hiss and the heartbeat are synthesized at runtime. BOT VOICES (voice/*/*.mp3) The Russian call-outs of the bots, generated with ElevenLabs text-to-speech on Adrian Garcia's (owner) personal ElevenLabs account with voices from his "My voices" (Gogi Kavkaz, Nester Surovy, Egor Gadzhiyev). Round 5 (lane 5c, 2026-09-24): eleven_v3 with a delivery per call-out (audio tags and stability: shouted or urgent in a fight, calm on a patrol); the previous takes (eleven_multilingual_v2, 2026-09-24) stay in assets/sources/audio/voice and build back with tools/prepare-voices.mjs --set v1. Lines, casting, delivery, cutting and levels by Claude Code for Adrian / Siantek; per-take prompt, voice, settings, date and request id in assets/manifests/voice-barks.json. MUSIC (music/*.mp3) The menu loop (music/lobby-1-1.mp3) and the extraction sting (music/extracted-1.mp3), instrumental, generated with ElevenLabs Music (music_v2_5, force_instrumental) on Adrian Garcia's (owner) personal ElevenLabs account, 2026-09-24, under that plan's terms (commercial use from Starter); no third-party recordings and no real artists in the prompts. Prompts, selection, loop cutting (3 s crossfade, 0.5 s circular padding), loudness (-24 LUFS loop, -22 LUFS sting) and MP3 encoding by Claude Code (lane A) for Adrian / Siantek with tools/prepare-music-ai.mjs --build. Per-file prompt, date, account and processing in assets/manifests/music-ai.json and assets/sources/audio/music/provenance.json. Loaded after the game starts, never preloaded.
