+
+# DNS5 16kHz
+
+Resampled subset of the [ICASSP 2022 DNS Challenge](https://github.com/microsoft/DNS-Challenge) dataset.
+
+All audio files resampled from 48kHz to **16kHz** and stored as **FLAC** (lossless compression),
+packed into tar shards.
+
+## Structure
+
+```
+clean/shard_0000.tar          # Clean speech (VCTK and other corpora)
+clean/shard_0001.tar
+...
+noise/shard_0000.tar          # Environmental noise (AudioSet, Freesound)
+...
+impulse_responses/shard_0000.tar  # Room impulse responses
+...
+```
+
+Each tar contains FLAC files with their original directory structure preserved.
+
+## Usage
+
+```python
+from huggingface_hub import snapshot_download
+import tarfile
+from pathlib import Path
+
+# Download
+local = snapshot_download("richiejp/dns5-16k", local_dir="/data/dns5", repo_type="dataset")
+
+# Extract all shards
+for tar_path in sorted(Path(local).rglob("*.tar")):
+    with tarfile.open(tar_path) as tf:
+        tf.extractall(tar_path.parent)
+```
