Question about supplementary dataset availability

[Peter Hutka]

Hello,

I noticed that the challenge documentation mentions a supplementary dataset containing 10 recordings from each hidden source (I0004 and I0007). However, I could only find download links for the small and large training sets.

Could you please clarify where the supplementary set can be downloaded, or whether it has not yet been released?

Thank you.

Dear Peter,

We included the supplementary dataset in the training set page during the unofficial phase, but we have now created a new page for the official phase because of the larger file sizes. We have included a link to the supplementary data here:
