Hi! My problem is that the starting signal level (without any sounds) is not 0 as it is supposed to be, but is 0.5 as it is shown on this figure. https://lh6.googleusercontent.com/--u3FmhSfoUI/TsZP8fhKo-I/AAAAAAAADEo/4cuk49qP9F4/audacity_level.png How it is possible to make it 0? Thanks in advance! ...
