- Look at the frequency content of your signal using spectrum.periodogram
- Decide on the basis of #1, which frequencies you want to filter.
- Design the filter using fdesign.highpass
- filter the data using filter()
Filtering contaminants out of a sound clip

Hi,
I'm trying to filter out a contaminant from a sound clip using Matlab. It sounds kind of like a low pitched horn. I know there are a lot of built-in Matlab filters that can help with this. Could someone explain the general process.
Any help would be appreciated?
Thanks

Sounds like you need a highpass filter.
