Hi. I was looking for some help please how best to attack this type of waveform in a speech recording? Thanks. The majority of the recording is fine but there are these occasional extremes.
I am using win10 and Audacity 2.3.1
Cheers
David
That looks like “wind blast”. Does it occur at the start of words beginning with “P” and/or “B”, and does it sound like a thump?
If so, then the cause is due to the person’s breath blasting onto the microphone. To avoid that, you should use a “pop filter” (also called a “pop screen”). See: https://en.wikipedia.org/wiki/Pop_filter
Pop screens are fairly inexpensive, or you can make a DIY version from a wire coat hanger and a piece of fabric from a (clean) stocking.
To improve a recording that has already been made, you can use the Equalization effect with the “Low roll-off for speech” setting: https://manual.audacityteam.org/man/equalization.html
Prevention is better than cure, so buying (or making) a pop shield is highly recommended.
A very belated thank you!!
