Does anyone know why parameters of C8C1I increases? #19

Snipaste_2024-08-17_22-06-50 Does anyone know why parameters of C8C1I increases? I try to mainly modify the config as

    "upsample_rates": [8, 1],
    "upsample_kernel_sizes": [16, 15],

or

    "upsample_rates": [8, 1],
    "upsample_kernel_sizes": [16, 1],

but neither of their parameters changed as shown in the table.

inspecting what you are trying to do, it should be more like:

"upsample_rates": [8,1], "upsample_kernel_sizes": [16,2],

though that alone won't be enough, you also need to update the iSTFT parameters gen_istft_n_fft and gen_istft_hop_size so you get perfect upsampling to 256 samples per frame

had done that. you can see that C8I also need it but it doesn't increase the parameters.
