Hi, I installed zita-jacktools-1.0.0 into my gentoo, and when running the harmdist example, I get the following error: python3.5 harmdist.py Traceback (most recent call last): File "harmdist.py", line 116, in <module> L1dB = 20 * log10 (L1) ValueError: math domain error I have no clue about what is wrong. Any help will be welcome. Cheers, Dominique -- If you have a problem and you are not doing anything to fix it, you are at the heart of the problem.
