I searched for tutorials but all are to remove background noise, and my video requires background noise but sometimes the wind in the micro very loud.
I have tried several plugins but I have not made it, I want to do exactly the opposite that makes the Noise Gate plugin, instead of eliminating all sound below x decibels, from above.
You want to use a compressor. Either the Track Compressor (which is on every track by default) or the Wave Hammer plug-in. Wave Hammer has a Volume Maximizer that also has the ability to Limit the volume to a given dB setting. For example if you set the output max to -10dB you will never get any audio the goes above -10dB. The Threshold setting determines when this kicks in (i.e., how soft a sound gets affected).
