No recording is used for them. ## Ambience recordings All ambience recordings are from [Freesound](https://freesound.org), each released by its author under **Creative Commons 0 (CC0 1.0, public domain dedication)**, verified on each source page (2026-09-25). The files were made from Freesound's public high-quality previews (MP3, about 128 kbps), not from the originals (which need a login); that is why their bandwidth is limited. Common edits: a loop of the stated length crossfaded into itself (equal power) and written with 0.25 s of the same loop before and after (so it loops without a gap whatever the MP3 decoder's delay), filtered as noted, normalized to the stated loudness, encoded as MP3 44.1 kHz CBR. | file | source | author | license | edits | |---|---|---|---|---| | `ambience/hq-room.mp3` | [R05-26 Office Scene](https://freesound.org/people/craigsmith/sounds/480722/) | craigsmith | CC0 1.0 | 40 s loop; band 110 Hz–2.6 kHz (as if through the wall of the next office); small-room reverb (0.8 s); the right channel is the same loop half a period later (width without phase); −30 LUFS; stereo 96 kbps | | `ambience/artillery-steady.mp3` | [R30-11 Large Guns Heard from Inside Building](https://freesound.org/people/craigsmith/sounds/486039/) | craigsmith | CC0 1.0 | 26 s loop from 2.5 s; band 40 Hz–3 kHz; −30 LUFS; mono 80 kbps | | `ambience/artillery-heavy.mp3` | [R22-08 Big Battle Ambience](https://freesound.org/people/craigsmith/sounds/479569/) | craigsmith | CC0 1.0 | 45 s loop from 10 s; band 30 Hz–1.4 kHz (drumfire through the walls); −28 LUFS; mono 80 kbps | | `ambience/artillery-distant.mp3` | [G43-14-25 Distant Explosions](https://freesound.org/people/craigsmith/sounds/438693/) | craigsmith | CC0 1.0 | 10 cuts (8 single explosions, 2 salvos of three) at 0.4 s intervals, each faded out over 1.2 s and normalized to −22 LUFS momentary maximum; band 35 Hz–2.4 kHz; mono 80 kbps | | `ambience/rain-window.mp3` | [Rain on Window, Reverberant room, Medium Perspective](https://freesound.org/people/silencyo/sounds/81819/) | silencyo | CC0 1.0 | 34 s loop from 11.5 s (after a drip); band 70 Hz–11 kHz; −30 LUFS; stereo 128 kbps | | `ambience/wind-winter.mp3` | [AMB Wind Howling, empty church close to window](https://freesound.org/people/Tonmeister88/sounds/557380/) | Tonmeister88 | CC0 1.0 | 60 s loop from 20 s; highpass 45 Hz; +7.7 dB to −30 LUFS; stereo 96 kbps | The craigsmith recordings are from a vintage optical-film sound-effects library (tags "Optical", "Vintage"), which suits the period: no modern traffic or voices. ## Loudness targets Measured with ITU-R BS.1770 / EBU R128 (K-weighted). Short sounds are normalized by their maximum momentary loudness (400 ms window), loops by their integrated loudness; true peak ≤ −1 dBTP. These are the levels before the volume sliders (at the default settings the effects bus is at −3.2 dB, the ambience bus at −7.4 dB and the master at −3.2 dB). | group | target | |---|---| | interface (button, toggle, tab, popover) | −31 to −33 LUFS-M; order refused −27 | | orders (move, attack, stamp, air) | −25 to −27 LUFS-M | | clock (pause, resume, speed) | −28 to −31 LUFS-M | | news | info −27, good −25, bad −25, critical −20 LUFS-M | | ambience loops | −30 LUFS-I (heavy artillery −28) | | distant explosions | −22 LUFS-M each, played 0 to −8 dB | | wall clock | −40 LUFS-M | | music | −17 LUFS-I, true peak ≤ −1 dBTP (at the default settings the music bus is at −10 dB) | ## Music Six pieces are original music for Culminating Point: "Parade Ground", "Morning Column", "Steppe Road", "Newsreel", "The Thaw" and "The Last Report". The seventh is Brahms's Andante moderato in the recording the Czech National Symphony Orchestra made for Musopen, released into the public domain. | file | piece | source | license | edits | |---|---|---|---|---| | `music/parade-ground.mp3` | Parade Ground | original music for Culminating Point | the game's own | 5 ms fade in, 0.3 s fade out over the last of its own decay; −1.3 dB to −17.3 LUFS-I (loudness range 2.1 LU, true peak −1.1 dBTP; the source's decoder overs, +0.5 dBTP, are gone); 44.1 kHz; MP3 128 kbps CBR stereo; tags and cover image removed | | `music/morning-column.mp3` | Morning Column | original music for Culminating Point | the game's own | 5 ms fade in, 0.3 s fade out over the last of its own decay; −1.7 dB to −17 LUFS-I (loudness range 4.3 LU, true peak −3.1 dBTP); 44.1 kHz; MP3 128 kbps CBR stereo; tags and cover image removed | | `music/steppe-road.mp3` | Steppe Road | original music for Culminating Point | the game's own | 5 ms fade in; the file ended in its last chord's reverb at −50 dBFS: a 1 s fade out closes it; −1.2 dB to −17 LUFS-I (loudness range 3.6 LU, true peak −1.5 dBTP; the source's overs, +0.1 dBTP, are gone); 44.1 kHz; MP3 128 kbps CBR stereo; tags and cover image removed | | `music/newsreel.mp3` | Newsreel | original music for Culminating Point | the game's own | 5 ms fade in, 0.3 s fade out over the last of its own decay; −0.4 dB to −17 LUFS-I (loudness range 4.7 LU, true peak −3.5 dBTP); 44.1 kHz; MP3 128 kbps CBR stereo; tags and cover image removed | | `music/the-thaw.mp3` | The Thaw | original music for Culminating Point | the game's own | 5 ms fade in, 0.3 s fade out over the last of its own decay; −2.5 dB to −17 LUFS-I (loudness range 3.3 LU, true peak −4.1 dBTP); 44.1 kHz; MP3 128 kbps CBR stereo; tags and cover image removed | | `music/the-last-report.mp3` | The Last Report | original music for Culminating Point | the game's own | 5 ms fade in (it opens on a note), 0.3 s fade out over the last of its own decay; −0.2 dB to −17 LUFS-I (loudness range 8.1 LU, true peak −1.9 dBTP); 44.1 kHz; MP3 128 kbps CBR stereo; tags and cover image removed | | `music/brahms-4-andante.mp3` | Johannes Brahms, Symphony No. 4, II.

Andante Moderato, Musopen Symphony, publicdomain/mark/1.0". Musopen asks, as a courtesy, to be credited, and not to sell its recordings as such. Measured with ffmpeg's `ebur128` (ITU-R BS.1770-4, true peak by 4× oversampling) on the source and on the decoded MP3. None of the six original pieces has a flat-topped (clipped) peak; two sources (Parade Ground, Steppe Road) decode a few samples over full scale (+0.5 and +0.1 dBTP, a master limited at 0 dBFS), which the gain removes. Each ends on its last chord and that chord's decay, with no new note in its last two seconds: an ending, not a cut. All seven pieces are matched by integrated loudness; the loudest 3 s of the marches (short-term maximum −19.8 to −21.4 LUFS) stay under those of the Brahms and The Last Report (−17.7 LUFS), so none of them jumps out.
