Analyzing DC Offset

The Normalize effect is supposed to analyze and remove DC offset at the users request; in my recent tests on 2.0 and newer Audacitys this does not seem to be working properly.

What’s the problem? Can you give steps to reproduce the issue?

@Edgar

The Noise Removal effect is not advertised as doing this analysis and removal but it does.

The Noise Removal effect has a 6 dB/octave high-pass filter at about 30 Hz. I don’t think that is in the documentation, but I don’t recall anyone ever asking about it before.

@Edgar

Quite a few months back there was some talk about splitting out the code for removing DC offset from Normalize and making it a separate effect of its own.

That discussion has gone on a lot longer than “a few months”
I’m in favour of a separate DC offset tool, though the lack of Effects management is a big stumbling block for the addition of any new effects.

@kozikowski

Yes. Everybody who already knows where the tools, knows where the tool is.

Absolutely
