Hello Wolf,

 

maby you can help me out with a problem I have with Speclab.I am using speclab to listen to sferics and whistlers.In the components window I can enable the humfilter ,the effect is very clearly visible on the spectrogram,but I can,t hear the difference on the speaker.Am I forgetting something or is it just not possible on some old soundcards.It works well on my desktop...Many thank in advance,
