## Example birdsong

`samples/birdsong.ogg`: "Fringilla coelebs.ogg", a chaffinch singing in a spruce
tree in Southern Finland, recorded by Oona Räisänen (Mysid), May 19, 2007.
The recording was released into the public domain by its copyright holder.

- Source and license: https://commons.wikimedia.org/wiki/File:Fringilla_coelebs.ogg
- Original file: https://upload.wikimedia.org/wikipedia/commons/f/f9/Fringilla_coelebs.ogg

The app analyses only its first six seconds and labels the result as an
example, never as an observation from a user's walk. The recording is unmodified.

## Test-only material

Generated sine-wave and silence fixtures in `private-fixtures/` are excluded
from publication and are never described as field recordings. `demoWave()`
also generates a synthetic tone for deterministic inference checks.
