 # Dataset Card for "down_on"
 
-[More Information needed](https://github.com/huggingface/datasets/blob/main/CONTRIBUTING.md#how-to-contribute-to-the-dataset-cards)
+This is a demo dataset for acoustic classification, consisting of utterances of *down* and *on* extracted from the
+`superb ks` dataset. 
+
+`down_on_hub.py` illustrates the methodology for creating such a dataset from wav files.
+`down_on_copy.py` was used to write the wav files.
+`down_on_create.py` is the more direct method.
+
+See the model `MatsRooth/wav2vec2-base_down_on` for the demo application.
