Gale 22Oct13: Personals like "I" and "my" are inappropriate in the Manual especially if they appear to be criticising Audacity as this comment is. See also the settings advice on the Wiki ( http://wiki.audacityteam.org/wiki/Noise_Removal#Improved_Noise_Removal_in_current_Audacity ). If you want this in then you need to rewrite it impartially (an "example" is appropriate for this IMO, but it does not seem much of an "example" with only two settings changed. Why not make an example (using the agreed example div) of a lot of noise within the music, where pushing the sensitivity slider up is the key? This seems to be the more common complaint about current noise removal - or isn't it?

• Steve 22Ict13: Fwiw, I agree that personals like "I" and "my" are inappropriate for the manual, but I don't agree that the comment is being (negatively) critical of Audacity.

Ailternative settings

Some users find the default settings in Noise Removal a bit too aggressive in that they can produce tinkly artifacts

Setting the "Noise Reduction (dB)" to about -12 will still have an appreciable effect on low level noise, but will produce much lower tinkly artifacts than the default settings.

Try increasing the "Frequency Smoothing (Hz)" a bit too - typically around 500 Hz, but for critical work it's best to experiment for optimum settings.

Reducing the "Sensitivity control (dB)" can also help to make the effect less aggressive, but is a bit tricky to use effectively. It is usually best left at the default 0.0 dB.

Many users require the settings to be quite aggressive so as to have some impact on bad recordings so the default setings are fine for them.
