NoiseSphere modifications to the twelve Blanket-derived recordings: excerpted to at most 35 seconds, loudness-normalized, converted to stereo 44.1 kHz / 128 kbps MP3. Playback additionally crossfades the loop boundary over 0.8 seconds. Reproduce with `scripts/prepare-audio.py`. Original authors do not endorse NoiseSphere. Preserve this file and the linked credits page with redistributed audio.

## Additional bird recordings (2026-09-22)

These four recordings are sourced directly from Freesound public HQ MP3 previews, independently of Blanket. All four source pages displayed CC0 1.0 when checked.
