The command I entered was:
audio-separator a.mp4 --model_filename model_bs_roformer_ep_317_sdr_12.9755.ckpt --mdx_segment_size=512 --mdx_batch_size=10 --mdx_enable_denoise --mdx_overlap 0.6
My system is equipped with 2 rtx3060 12gb.
I also used UVR-DeNoise.pth to remove noise.
It is a sound that does not exist in the original, but the noise is not removed.
How do I remove the attached noise?
What kind of sound is the attached noise?

I found that setting the --amplification option to a very small value (e.g., --amplification=0.001) resolves the issue.
The default value for this option is 0.6.
