Try a parametric EQ. Start with very narrow Q, gain all up. Sweep the frequency band to find the offensive freq. Then cut gain to notch it out and listen for unpleasant artifacts. If is sucks all the “air” out of the guitar, it’s too much, bring the gain up a bit. I wouldn’t try to remove all the squeaks, it’s a natural part of steel-string performance and will sound weird and unnatural if completely removed.
I’ve been looking for the same thing. I’ve noticed that zooming into sample level in the sample editor you can always see the squeaks by the jagged wave forms. I’ve been wondering if anyone would ever develop a plug to range select a squeak and then interpolate the smooth curve? Anyhow, I’ll give the deesser a go. Thanks.
I always use a narrow band in a multi band eq. For years… sometimes a de sser. My goal is to control it. Not eliminate it. It is part of the instrument’s charm.
If all you need to do is get rid of guitar string squeaks in one recording it’s a bit much to buy the whole SpectralLayers, even though it would do a great job.
But maybe there is a demo version you can use for 30 days and get rid of as much as you have time for.
SpectralLayers is a phenomenal tool for manipulating sounds in all possible ways and then some!!!
If that’s not your cup of tea there is always the DeEsser.
