“Just curious what you are doing that has you mostly using the noisespray tool?”
Location background audio from cameras. There’s often low level wind noise or the like usually under 300 Hz but up to 500 Hz where its sometimes easier to delete that frequency range altogether and replace it with the noise spray at about - 40dB or thereabouts, depending on the overall bg sound level. The constant noise spray level provides a feeling of a more peaceful ‘location’ replacing the annoying rumbling of the wind. Where that low level wind noise is only occasional, my preference is to use the clone stamp to copy a section of the clean ‘no wind noise’ area and use that to replace the wind noise areas, again usually under 300 to 500 Hz.
Notwithstanding the above, I still add an EQ FX at the track level in Vegas Pro which fades out bg audio usually from 110 to 40 Hz.
