Accusonus has published a video on its drumatom drum bleed reduction plugin, showing the difference between drumatom² and a noise gate.
Noise gates (and all other drum bleed suppression tools that are actually based on the same principle) are simple tools that can only remove bleed when there’s no useful signal.
Drumatom removes drum bleed not only during pauses but during exact drum hits as well. This enables you to quickly create a punchy and detailed drum sound by performing deeper individual processing on drum tracks.
Compress and EQ your Kick track more aggressively, since there’s less or no bleed.
drumatom² for Windows and Mac (VST/AU/AAX) is available for $299 USD. A free trial version is available for download.
