Sound demos for "Reverberation Modeling for Source-Filter-based Neural Vocoder"

 

 

Write in front:

We also successfully used the H-GTI to achieve reverberation modeling using the solo volin database (totally 5 utterances) in the DDSP paper (reference [24] in our paper).

For the ASP in H-GTI, the ASP was first trained on the URMP database (used in reference [23] in our paper) which contained multiple types of instrument sounds, then fine-tuned on the solo violin database (which is a little different from this paper's method for ASP).

For the PSP in H-GTI, the PSP was trained on the solo violin database from scratch (which is the same as this paper's method for PSP).

The training set is the front 4 utterances in the solo violin database.

The test set is the last utterance in the solo violin database.

The result of H-GTI:

Following is the results in this paper:
