The 50-second source was reduced to a 32-second 44.1 kHz stereo MP3 loop. A two-second end-to-start equal-power blend avoids a hard seam, and the encoded track is balanced to -24.03 LUFS at 128 kbps. The final MP3 retains the title, creator, Pixabay Content License, and source URL in its metadata.

All seven files were resampled to 48 kHz stereo MP3. Tactical cues were silence-trimmed, equalized by role, and balanced to approximately -17.5 to -19 LUFS. The rain and fire recordings were reduced to stable excerpts, balanced near -25 LUFS, and rebuilt with a one-second end-to-start crossfade so repeated playback does not introduce a hard seam.
Battle playback uses track-specific loop trims for high-crest fire and mountain-wind recordings. Fallback volume is calculated from the measured integrated loudness of each active music-and-ambience pair, so quiet and loud BGM masters retain the same perceptual offset. Automated mix checks measure the actual encoded files across all 66 campaign battles and keep ambience 14-18 LU below its BGM; fire and snow-wind peaks must remain at least 1.5 dB below the paired music peak.
Narrative Interface Cues

The narrative cue was resampled to 48 kHz stereo MP3, silence-trimmed to an approximately 1.0-second excerpt, fade-in/out processed, and high-pass and low-pass filtered for unobtrusive playback over story music.

All three cues were silence-trimmed, resampled to 48 kHz stereo MP3, fade-in/out processed, and high-pass and low-pass filtered. Recovery was reduced to approximately 1.9 seconds, reward reveal to 1.4 seconds, and burn damage to 0.7 seconds so feedback begins promptly and does not mask the next action.
Derived Terrain Movement One-shots
The following short movement clips were derived in-project on 2026-07-23 from the two Pixabay-licensed recordings already listed under Sound Effects. No additional recording was introduced. Each derivative retains the original creator and Pixabay detail-page URL in its MP3 artist/comment metadata, as well as in this document.

The derivatives are 0.34-0.48 second one-shots. They were excerpted from separate points in the parent recordings, resampled to 48 kHz stereo MP3, given 8 ms attack and 55 ms release fades, terrain-specific EQ, and conservative loudness/peak balancing. Runtime playback samples surfaces across the full movement route, treats rain and passable river-bank/ford tiles as wet, prevents the same active clip from doubling, and caps foot and hoof groups at two voices each. Existing combat pools also use per-track gain compensation derived from integrated loudness measurements so randomized variants do not jump sharply in perceived level.
