Asteroid model
Description:
Refer to paper "Multi-Decoder DPRNN: High Accuracy Source Counting and Separation", Junzhe Zhu, Raymond Yeh, Mark Hasegawa-Johnson. https://arxiv.org/abs/2011.12022 Demo Page: https://junzhejosephzhu.github.io/Multi-Decoder-DPRNN/ Original research repo is at https://github.com/JunzheJosephZhu/MultiDecoder-DPRNN
This model was trained by Joseph Zhu using the wsj0-mix-var/Multi-Decoder-DPRNN recipe in Asteroid.
It was trained on the sep_count task of the Wsj0MixVar dataset.
