I am new to audio, I don’t know the terminology and process for what I want to do, I only want to do one thing. I have severe tinnitus and there is a therapy called music notch therapy. I would like to try. It involves establishing the frequency range of the tone one hears and then eliminating that frequency from the music MP3. In my case the tone is at 10500Hz. To use the therapy, I would eliminate a section of sound 1 octive wide, centred on the 10500 Hz.
Can I do this, and how do I, with Audacity and apply it to all my music files?
Here’s what you need to do:
- Get Audacity: First things first, download and install Audacity on your computer. You can grab it for free from their official website.
- Import your music: Open up Audacity and import the music file you want to work on. Just go to “File” in the top menu and choose “Open.”
- Find that annoying frequency: Now, let’s figure out the frequency range of your tinnitus tone, which is 10500 Hz in your case. Audacity has a cool frequency analysis tool that can help. Select a small section of your track where the tone is playing (a few seconds is fine), then go to “Effect” in the top menu, choose “Analyze,” and click on “Plot Spectrum.” You’ll see a graph showing the frequency analysis.
- Cut out that tone: To get rid of the frequency range around 10500 Hz, we’ll use Audacity’s notch filter effect. Go back to the top menu, click on “Effect,” and select “Notch Filter.” In the dialog box, set the center frequency to 10500 Hz and the width to 1 octave (you can tweak this if you want). Leave the rest of the settings as they are.
- Give it a listen: Before applying the effect to your whole track, it’s a good idea to preview it first. Just hit the “Preview” button in the “Notch Filter” dialog box to listen to the modified audio. If it sounds good to you, click “OK” to apply the effect.
- Save your modified audio: Once you’re happy with the changes, save the modified file. Click on “File” in the top menu and choose “Export” or “Export as” to save it in your preferred format (like MP3).
If you want to do this for all your music files, unfortunately, there’s no automatic way in Audacity. You’ll have to repeat these steps for each individual file.
Refer to an audiologist before trying tinnitus therapy.
