Which parameter determines output samplerate? 48 kHz gets resampled to 44.1 kHz but why?

[pucgenie]

Does it depend on the selected model?
EDIT: I see facebookresearch/demucs#288

[CarlGao4]

It depends on the model you've selected

[CarlGao4]

That's strange. I don't think that overlap greater than 0.5 is reasonable, actually
You can read the meaning of each parameter from the usage

[nickyvdz-art]

Sure thing; like I said previously, I was just playing around to see the variety of outputs; I shall try 0.5 - again, appreciate your feedback, thank you.

[nickyvdz-art]

but its still 100% cpu?
