It helps for sure, I needed it to listen to a round table with 4 participants who each have a different level varying from 10 to 15 DB (impression that the velocity is twice as strong or half as weak).
What is difficult is the setting without a VU meter, in order to "see" the lowest level to use it as an "uncompressed" reference, and to be able to "align" the compression of the strongest signals with the weakest. This would avoid "compressing" the signal too much, which would avoid increasing the background noise with the reverberations.
One thing that's missing is the signage and it's hard to understand, for example, if the ratio is 2:1-3:1 or 4:1 or if the attack is in milliseconds or whatever.
I managed to adjust it by ear and I don't need it often so it's fine for me, but for those who aren't too used to it, by reading the comments it seem it's not very easy for many.
It was a good idea to make this plugin, so thanks to the developer. Good job.
