+# Audio Dataset Manager
+
+## Required Space secrets
+
+- `token_login`: login token for the UI.
+- `auth_acess_data`: Hugging Face token used to read private datasets and push results.
+
+## Main fix
+
+The Python module `df` is provided by the PyPI package `deepfilternet`.
+It must be declared in `requirements.txt`:
+
+```text
+deepfilternet==0.5.6
+```
+
+The application now loads DeepFilterNet lazily, validates audio, normalizes
+without division-by-zero, uses safe pandas assignments, and reports clear UI
+errors instead of terminating the Space during startup.
