What datasets are specifically mixed in the HIFI-CODEC paper？

[Bravee]

Hello, I mixed the three data sets libritts, aishell and vctk according to the dataset set in the HIFI-CODEC paper, which lasted about 400 hours, but the performance of the trained model could not reach the performance of the pretrained model you gave. May I ask what datasets are specifically mixed in your paper "and more, with a total duration of over 1000 hours"?
