I’m already working on fixing this.Ģ- Frequency smoothing often sounds bad because it tends to reduce lower frequencies in order to avoid musical noise but I didn’t thought of your use case. What is doing now is wrong and only works for brown or pink alike noises. Spectral whitening should preserve the envelope of the residual signal and reduce only peaks and nulls that are far from it. Here are my answers:ġ- Residual whitening is badly implemented and I know that. The plugin does not work correctly in Audacity, while it would be really awesome if it could.I know it’s probably very complicated to implement, but could produce some fine results. In fact, it’s a good field for experiments, I mean to devise some way of dynamic adjustment of the FFT window length according to a differential threshold (i.e.
#Ardour noise reduction windows#
I’m not sure whether there should be such a parameter (as well as “overlap”) but there can be some situations when shorter FFT windows produce better results, as those are less aggressive, especially to sounds short attack times. nature sounds, ambience, etc.), especially those with useful background noises (e.g. There’s no frequency smoothing parameter (like in Audacity), which is very useful to clean some non-musical sources (e.g.Residual whitening generates repetitive noise patterns, which is no good as I’ve found some situations where those patterns can be easily heard.Thank you so much for your efforts, lucianodato! I’ve just tried the latest git master, and noticed some minor things to improve:
