Re: How to Notch above 10,000MH
I also played with the Q in Notch Filter, and end up using 0.5 to 0.2 to widen the notch in the music for tinnitus. What I don't understand is the Q vs the Stop Band Width. For example, if I use white noise and 10000 Hz frequency and stop band width of 1.0, I get a very wide notch. If I use the same frequency in Notch Filter, and Q=1.0, I get a very narrow notch in Plot Spectrum. Why is that?

Gale,
Can the frequency line be edited in Audacity? Can you give me step by step instructions?
Thanks!

What version of Audacity are you using? See the pink panel at the top of the page.crowwoods1 wrote:Can the frequency line be edited in Audacity? Can you give me step by step instructions?
If you have an old Audacity version and so you are not getting an error in Band Stop when you type in a Centre Frequency above 10000 Hz, then you don't need to edit the plugin. If you do need to edit it, I already gave instructions. Open it in your favourite text editor such as Notepad.

The two plugins have different purposes. If you want a narrow notch, use Notch Filter.crowwoods1 wrote:I also played with the Q in Notch Filter, and end up using 0.5 to 0.2 to widen the notch in the music for tinnitus.

Thank you, Gale!!!!
I got it this time. I have never used Notepad before. I edited the line in Bandstop.ny like you suggested to bring the limit up, and it works.
