Audacity Try it →Watch full video →Mike Russell · Aug 2024

Demo summary

The user shows how to switch to Spectrogram view in Audacity to identify and delete specific low-end rumble frequencies using the Spectral Delete tool.

Step-by-step

Click on the three dots on the audio track
Change the view from Waveform to Spectrogram
Select the specific frequency range (low, mid, or high) containing the noise
Go to the Effect menu
Select Spectral tools
Click Spectral delete

Options

Select partial frequencies in the mid-range or high-range for targeted removal

Tips

Use this tool for noise reduction in specific frequencies if you see something in the spectrogram that needs to be removed
Apply noise reduction effects to see a dramatic visual difference in the spectrogram

Highlights

“there's a lot you can do now in spectrogram you couldn't do before such as selecting frequencies”
