Why is prompting Suno not enough to remove cheers or crowd noise?

Prompting can reduce the chance of Suno generating audience sounds, but it does not edit an existing waveform. Once cheers, applause, clapping, or arena noise are baked into the rendered song, another prompt usually means regenerating the song and risking a different vocal, arrangement, or mix.

Use Heavy Decrowd for Suno songs when you already like the song and need a post-generation cleanup step.
