Water: Gentle Waves - Quiet Beach — amholma (Andrew Holman)
https://freesound.org/people/amholma/sounds/376795/
HQ preview: https://cdn.freesound.org/previews/376/376795_6128004-hq.mp3
Excerpt starts at 18 seconds. Creator describes small waves washing onto a quiet beach in Destin, Florida. Replaces both the close-up lapping and stronger ocean recordings rejected in listening feedback. This is optional coastal ambience, not a literal recording of the illustrated lake.

Birds: Summer_evening_Sweden — Prauchi
https://freesound.org/people/Prauchi/sounds/835724/
HQ preview: https://cdn.freesound.org/previews/835/835724_2712729-hq.mp3
Excerpt starts at 8 seconds. Used as an illustrative woodland bird layer, not a species/location prediction.

Breeze: Soft Wind Trees Moving Ambience.wav — jordir
https://freesound.org/people/jordir/sounds/360568/
HQ preview: https://cdn.freesound.org/previews/360/360568_501389-hq.mp3
Excerpt starts at 10 seconds.

Night: Night Ambience — parret
https://freesound.org/people/parret/sounds/481883/
HQ preview: https://cdn.freesound.org/previews/481/481883_8143650-hq.mp3
Excerpt starts at 20 seconds. Creator's processed field-recording blend of indoor and pond ambience.

Modifications: 32-second excerpts, low-rumble filtering, loudness normalization (-22 LUFS target, -3 dBTP), 24 kHz stereo MP3 at 96 kbps. Gentle waves use a 90 Hz high-pass, 2800 Hz low-pass and -27 LUFS target with -5 dBTP ceiling, preserving natural wave timing. Runtime uses a two-second circular overlap, phase-specific gain mixing, indoor filtering and master volume. Wind layer reduced to let the quiet waves remain distinct. HQ previews, not original lossless masters. The assembled landscape/soundscape is artistic, not actual local conditions. No synthesized wildlife.
