richiejp/dns5-16k

DNS5 16kHz

Resampled subset of the ICASSP 2022 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

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)
