DataSEC v1

This is a Hugging Face mirror of the CC-BY-4.0 v1 DataSEC archive from Zenodo record 10.5281/zenodo.15340689.

DataSEC is a sound event classification dataset for environmental noise. The files are organized by class, with selected classes further organized by subclass.

Important version note: the latest Zenodo version of DataSEC uses cc-by-nc-sa-4.0, so this repository intentionally mirrors the earlier PT_DATASET_250314.zip v1 archive, whose Zenodo metadata is cc-by-4.0.

Verified Archive Statistics

The v1 Zenodo description text mentions 5,024 samples and 23 hours 32 minutes. The actual PT_DATASET_250314.zip archive downloaded from the CC-BY-4.0 v1 record contains the following verified contents:

Item	Value
WAV files	3,226
Top-level classes	22
Subclasses	15
Total duration	15.27 hours
Audio format	WAV, PCM 16-bit
Sample rate	44,100 Hz
Channels	Mono

Files
