Forever ago I used a hard limiting function in Syntrillium Cool Edit Pro that would basically delete the highest 3-6 dB peaks of a wave and amply the rest up by the 3-6 dB that was deleted. This prevented clipping and since those peaks were at most 1% of the wave file in total, nothing significant was missed from the result, but the overall level was a lot better.
The use case is basically a wave file that has a few mic bumps or people pronouncing the letters p or b too loudly in the mic and these few bursts caused the recording software to lower the level to prevent those sounds from clipping, but the entire recording is too quiet now. I want to just cut those off and amplify the rest while being sure that the amplification doesn’t cause any clipping.
What’s the best way to do this in Audacity?
to reduce plosive thuds, (pees, bees), a high-pass filter should be used first.
