FUSER
by Mastering The Mix · Resonance Suppressor · Sidechain unmasking / dynamic EQ
Not rated yet
FUSER is an unmasking plugin from Mastering The Mix: placed on one track and fed another by sidechain, it detects where they clash and ducks those frequencies with dynamic EQ.
A Resolve Conflicts button sets a starting point, and a Phase Analyze feature finds the best phase rotation when layering similar sounds such as kicks and bass.
Best for: Drums, Bass, Vocals, Keys & Synths. Genres: all genres.
Keywords: bass, sidechain input, dynamic, kick, vocals, corrective, drums, mid/side, mixing, samples & loops.
What it does
FUSER aims to "fix clashing frequencies." You load it on the track you want to duck and sidechain the dominant track into it, for example kick into bass.
- Conflict display: a red glow shows mid-channel conflicts and a yellow glow shows side-channel conflicts.
- Resolve Conflicts: one click sets processing that reduces channel conflict and masking without overdoing it.
- Manual nodes: double-click to add a node, then set amount, mid/side, Q, attack and release per node; a Delta button lets you hear what is removed.
- Phase Analyze: finds the optimal phase rotation to reduce cancellation when layering kicks, basses and similar sounds.
It has a free trial and a 30-day money-back guarantee.

When to use it
FUSER overlaps with sidechain dynamic EQs such as FabFilter Pro-Q 4 and Waves Curves Equator, and with resonance tools like oeksound soothe3. Pick it when you want automatic detection of where two tracks clash plus phase alignment for layered sounds. Pro-Q 4 gives more general EQ control, and soothe3 is the choice for taming resonances within one track.
- Best for: kick and bass separation, making room for vocals under music, and layering kick or bass samples.
- Genres: any style, especially electronic, hip-hop and pop with dense low end.
- Look elsewhere if: you need very fast attack or lookahead for sharp transients.
- Standout: Phase Analyze for layering, alongside the sidechain ducking.
What producers say
MusicTech praised its filters and phase tool, with minor complaints about setup and attack speed.
- MusicTech (2023) scored it 9/10 and said "Phase Rotate is a must-have for anyone who likes to layer drum sounds."
- Gripe: MusicTech found optimal settings fiddly to dial in and noted a minimum 1 ms attack with no lookahead.
