I was listening to audio file and notices that the person’s voice is very sibilant. It looks like one can fix the problem by following the youtube tutorial below.
The solution is offered in audacity forum here.
Here are the latest improvements to the plug-in I am developing for filtering out of wet mouth noises and clicks from my narrations. I also present a de-esser using similar methods that fell out as a by-product. De-Clicker is designed for filtering of natural but undesirable noises that take a few milliseconds to decay, not for repairing spikey damage to a digitized signal.
Step 1: Download DeEsser.ny
We need DeEsser.ny file and add it to our plug-in folder in audacity
Step 2: Find Audacity folder
Step 3: Add DeEsser.ny to that folder
- Go to Generate tab
- Add/Remove Plag-ins
Step 5: Select audio and apply the deesser
