How do I get rid of static noise on Audacity?

I'm trying to fix up Clair de Lune here, and during the song it goes really loud, causing a static sound. Anyway to get rid of that sound on Audacity?How do I get rid of static noise on Audacity?
In short - no.

Although the format of a file can affect the quality it does not apply in this case. (Audacity does not recognize the flac format.)

Whether recording direct to tape or digitally there is a limit to the level which can be recorded without distortion.

Classical music tends to have a much wider dynamic range than music recorded with airplay in mind such as rock, country etc.

You could also be referring to a band of that name, a song on a Madonna album or an artist by that name.

I checked Wiki.

If this distortion (asperity noise / clipping) only occurs during the loud passages it is now part of the audio and cannot be separated or removed.

If the waveform is normal until the loud passage/s and the upper and lower portions of the waveform are cut off straight and level in the loud passages (the waveform looks like a solid block) there is nothing you can do. The staticy, crackly sound can't be removed in the same way an individual instrument can't be removed.

The noise removal function will not be of any help. It is intended for constant low level noise such as from an air conditioner or fan.

The only remedy is to find another recording of the piece or if recording it yourself record it at a lower level but adjust the level at the loud section before recording the whole track.How do I get rid of static noise on Audacity?
It probably has something to do with the quality of the file. You should be working with a WAV or a FLAC, not an MP3, as MP3s are lossy and therefore low quality. If you can't find a higher quality version of the file, try using noise removal.
