Why it doesn’t crackle
Boosting a sound can push its peaks past the loudest level a file can hold, which causes harsh clipping. Here the loudest moments are rounded off gently instead, so speech gets louder without crackling. A huge boost on music still changes its character, so go step by step.

200% is about +6 dB, which sounds clearly louder. 400% is about +12 dB.
