Hello & Happy new year! I am actually working on a master with the trio Ardour-Audacity-Rezound, It works fine as usual! The master is good, but there is some artefact I want to erase in the spectre itself without losing too much of it. I mean without erase some frequencies in the spectre. But I would like to erase just the little artefact, working if possible on the graphic itself - the spectral representation. Do you know a free software which could do this kind of job? Thanks a lot for you answer cheers Julien
