Re: Problems with the new Noise Reduction replacing Noise Re

I don't know exactly what you did, but if you reduced Sensitivity of the new slider to 0, because the old slider used 0 dB, that could cause this. I am sorry if we did not make this clear, but the new and old slider settings are not comparable. Better to leave the new slider at 6.

Re: Problems with the new Noise Reduction replacing Noise Re

darrendeans I understand you use default settings with 2.0.6. What settings did you use for 2.1.0 and what attempt did you make to vary them from defaults? The old effect defaulted to 150 Hz frequency smoothing. The equivalent of that setting in the new is 6 bands, if your sample rate is the usual 4...

Re: Comparing Noise Removal/Reduction between 2.0.6 and 2.1.

I've still have a bad feeling about the frequency smoothing. It should imo be logarithmic and not linear.I' Robert I don't understand. Do you mean the frequency "distance" over which it works should be according to a logarithmic scale of frequency or did you mean some other logarithm? As it works n...

Re: Comparing Noise Removal/Reduction between 2.0.6 and 2.1.

I do not understand. Is not the default sensitivity setting a good one? I have thought that Sensitivity more naturally pairs with the Profile. Though you specify it in part 2, not part 1, it determines "what is noise" with the profile information, not "what is done to noise." I hope we can reopen th...

Re: Comparing Noise Removal/Reduction between 2.0.6 and 2.1.

Hi Paul I had similar thoughts while listening to the podcast. Good that you've commented on this. I've still have a bad feeling about the frequency smoothing. It should imo be logarithmic and not linear.I' ve just made a test with a buzz tone at 100 Hz and 60 harmonics. The noise profile is taken ...

Re: Comparing Noise Removal/Reduction between 2.0.6 and 2.1.

Btw, a pity that Daniel hasn't more talked about the spectral selection and its related tools. Perhaps something for another podcast. Robert For one thing, it is hard to demonstrate in a podcast, of course. For another, it appears from his brief remarks at 21:50 that Daniel is himself unfamiliar wi...

I've still have a bad feeling about the frequency smoothing. It should imo be logarithmic and not linear I'm having trouble with "Frequency Smoothing" and "Sensitivity". I don't know how to advise people about these controls other than "leave them at their default settings" (which defeats the point...

Comparing Noise Removal/Reduction between 2.0.6 and 2.1.0

Thanks to Daniel Lewis for reviewing version 2.1.0 so promptly at this podcast: http://theaudacitytopodcast.com/whats-new-in-audacity-2-1-0-tap216/#disqus_thread Discussion of noise reduction goes from about 6:50 to 16:30. Also that page contains three audio clips, one "before" and two "afters" comp...
