confusing about the meaning of the evaluation result

Open iPwnXX opened this issue 3 years ago • 2 comments

In the test example jupyter notebook, for some metrics the enhanced result is smaller than noisy one's, while some's are larger; e.g, PESQ should be the larger the better, but it's not the case in the demo.

and the scale/range of the result isn't mentioned in readme, I know some lie in 0 to 5, but not familiar with others.

Hi iPwnXX

Thank you for your interest in the package. The enhanced signal SHOULD have a larger PESQ score. But if you listen to the example, you will notice, that the "enhanced" signal is quite bad. So it's not unexpected, that the PESQ score is lower than for the noisy signal. Maybe I should replace the example wav files.

Regarding the range: Most of the metrics are explained in this book. I will add the ranges to the readme asap (not before september).
