I always have some hurting sounds, because the recorder/chair was moved, the table was hit, etc…
I would like to safely listen to my recording without worrying about a high sound that irritated the ears
It’s going to be pretty-much impossible to filter-out those shoulds without affecting the voices.
The human voice contains many simultanous frequencies, as do the noises, and the frequencies overlap.
Of course, in-between speaking you can mute the sound.
High-pass filtering (say, around 200Hz) can filter-out low-frequency noises without much affect on inteligability. If you have very-high frequency noises you can also try a low-pass filter somewhere around 6000Hz.
For something like a squeek, you can try a notch filter. Select the part with the squeek, then Analyze → Plot Spectrum and maybe you can see the frequency that needs to be filtered-out. It won’t be perfect, but it might help.
If the noise is louder than the speaking, compression may help a little. (Compression tends to make quiet parts louder and/or loud parts quieter.)
I have a recurrent problem: how to remove all sounds that can hurt the ears from an interview recording?
The solution is mainly better microphone placement. Maybe lapel mics.
Interviews are rarely perfect because you are usually interviewing amateurs in an imperfect environment.
If you watch the TV news, you will see reporters on the street getting the directional mic within a few inches of the speaker’s mouth. Some environemental noise gets through, but most of the time the results are acceptable. Sometines there is a barking dog, or a siren, etc., and it’s distracting, and sometimes they have to pause the interview.
In the TV studio, lapel mics are the standard. Sometimes a guest will touch the mic or touch their chest so that the mic makes a distracting sound, but the reporters know not to do that.
