# Assets directory Runtime utilities populate this directory with generated audio such as the wake-word acknowledgment tone (`wake_acknowledgment.wav`) and the placeholder voice sample under `voices/`. The files are intentionally created on demand so binary artifacts do not need to live in version control. Any legacy acknowledgment recordings (for example `rex_wake_acknowledgment.wav`) are deleted automatically the next time the helper runs so that outdated binaries cannot re-enter Git history. Custom wake-word models (`rex.onnx`) and any demo audio clips are ignored by Git for the same reason—drop them into the repository when experimenting, but expect a clean checkout to contain only source files.
