I currently use version 1.3.7 under Windows XP SP2.
Blatter is the main problem for me (I am not sure if it is the exact word). These can be seen as spikes in the signal. In version 1.3.7 I found a way to remove them (‘Repair’ under the ‘Effekt’ menu) but it can be done one-by-one so it generally would take too much time to remove them. ‘Repair’ seems to me a sophisticated tool and if we could find automatically which zones should be repaired it could save much time. Any idea?
