DCASE 2026 task 1 - evaluation set (submission)

This dataset is provided for generating and submitting results for task 1 of the DCASE 2026 challenge.

It includes sounds and their descriptive metadata (title, tags, description) which can be used as model input. The sound files have been anonymised, hence the mapping between the anonymised file names and the file names as used in the annotations (official evaluation dataset) is not included. Ground truth labels are not included either.

Please refer to the submission package for submission instructions.
