I would test different combinations of clash threshold, volume, audio suppression to find what works best. It will really vary a good amount for each saber.
As noted you can also try
#define FILTER_CUTOFF_FREQUENCY 100
#define FILTER_ORDER 8
Since I don’t have any sabers that exhibit this I haven’t tested all possibilities so I gave some starting points but it will be up to each user to find what works best for their specific saber.
Ideally, you want the saber to react to all physical “hits” but not have false clashes from loud sounds or hard swings (unless you hit something). Once you’re able to eliminate false clashes you can still fine-tune by adjusting all the defines together.
