I’m hoping that someone here might be of assistance. I am looking for a modified Nyquist Band Stop Filter plugin that would go over the current limit of 10Khz. I am thinking maximum 20Khz would be enough as it is the suggested maximum audible frequency for humans.
What do I need this for? Notch therapy. Notch therapy is used for Tinnitus reduction and I have had VERY positive results for other frequencies that I’ve been able to use this method on. I even tried this to help my father-in-law who has had Tinnitus for a long time and he says it is quiet now, almost non-existent. I have done the files as per the instructions at this site http://www.notchtherapy.com/ As far as I can tell, the need is for a wider 1 octave area to be notched as compared to the “Notch filter” which only notches a smaller frequency area. My current tinnitus is around 12Khz and I would like to see if I can beat it down with proper filtering.
The machine I’m currently using Audacity 2.1.2 with runs OSX 10.9.5. The 10Khz frequency limited band stop filter was downloaded from here http://wiki.audacityteam.org/wiki/Nyquist_Effect_Plug-ins#Band_Stop_Filter
Any help with this is greatly appreciated as this really has the potential to help many people out there!
