## Edits

Excerpts are high-pass filtered at 35 Hz and low-pass filtered at 12.5 kHz,
peak-normalized to 0.78, resampled to 32 kHz and encoded as MP3. Effects are
mono at 96 kbps; continuous beds are stereo at 128 kbps. Effects have leading
silence trimmed with a 5 ms guard and gentle edge fades. The water and wind
beds use wrap crossfades, preserving continuity when their decoded buffers
loop. The game varies playback pitch slightly, alternates recordings and
applies distance filtering. Carronades, long guns and chase guns use different
report pitch, weight and tail duration, with a separate timber carriage layer.

These edits do not change the CC0 status of the source material. The remaining
procedural fallbacks and game-specific cue arrangements are part of the game.
