Buzzing sound near lower frequencies

[ghost]

I've been training a reverb removal model for about 160 000 steps on a single GPU. Near lower frequencies there is an audible 100 Hz buzzing sound. Will this clear up with more training or is it a limitation of the model?

This issue is likely related to the limitations of the model itself. It seems that the frequency band splitting approach may not handle lower frequencies with sufficient precision. You could try experimenting with finer-grained processing in the low-frequency range, but the buzzing sound might persist if it's a fundamental limitation of the current model design.
