About a month ago I developed tinnitus in my right ear. One of the methods they are trying to treat it involves playing white noise or music for a few hours every day that have the frequency at which you hear the ringing removed. So for example, if your ringing was at 4,300 hz, you would listen to white noise with 4,300 hz removed as well as some above and below that pitch.
Is there a free simple tool that will do this? There are places you can get it done online but that costs money and I'd rather do it myself.
You can do it with white noise or music, but the results are supposed to be better with white noise.
Any freeware DAW will come with stock EQ plug-ins you could use man. Try Reaper or similar.
