In sentence: "... many common and useful algorithms in this space, it is hard to **_imaging_** the field without it. ..." "It is hard to **_imagine_**..." is correct.

Improvement recommendation: For `print_metrics` (and elsewhere), recommend using `np.median()` instead of `np.mean()` to align with SiSEC2018.

hi all! i have a short question. the "original" definition of SNR from 2006 (by E. Vincent) - https://hal.inria.fr/inria-00544230/document - is about ||s_target + e_inferf|| / ||e_noise||. but your book...

In Fig.26, the description words, "Convolution with 2D input with a 5x5 kernel and padding of 1.", may has an error? The '5x5' kernel should be 3x3 kernel?

According to the foundational paper, Performance Measurement in Blind Audio Source Separation, SAR should be defined as sources-to-artifact ratio, not source to artifact ratio.

Small typo: "but overlap with on another." Should say "one another" Perhaps the language could be clarified a bit to indicate whether you mean each window will have some overlap...
