Training XTTS HiFi-GAN to Upsample from 22,050 Hz to 48,000 Hz

[kikozi2000]

Hello,

I would like to ask if it's possible to train the HiFi-GAN model to upsample from 22,050 Hz directly to 48,000 Hz instead of the default 24,000 Hz.

I'm planning to make the following changes:

Use a dataset with 48 kHz high-quality audio samples for training.
Adjust the model configuration (e.g., set target_sample_rate to 48,000 Hz).
Are there any other important considerations or adjustments I should be aware of when training the model for this higher upsampling rate? Any advice or suggestions would be greatly appreciated!

Thank you!
