Product Name: FUSER Product Type: Frequency masking (unmasking) plugin Brand: Mastering The Mix Primary Use: Finding and fixing frequency masking between two tracks Best For: Kick and bass, vocals and instruments, layered drums, dense mixes Latency: Zero Formats: VST3, AU, AAX Platforms: macOS 10.15 or higher (Apple Silicon native), Windows 10 or higher License: 2 license seats as standard Free Trial: 15 days Description FUSER by Mastering The Mix fixes frequency masking between two tracks. It analyses both signals, shows where they clash in the mid and in the sides, and places sidechain-triggered dynamic EQ cuts in one click, so each element keeps its space only when it needs it. Phase Analyze sets the best phase rotation for layered sounds, and FUSER runs with zero latency. How To Use FUSER Put FUSER as the last plugin on the track that should move out of the way. Send the more important track into FUSER's sidechain input. Click Resolve Conflicts, then fine-tune any node's depth, Q, attack, release and mid/side setting. For kick and bass, put FUSER on the bass and sidechain the kick, so the bass moves out of the way only when the kick hits. Key Features Visual masking detection between two tracks, with mid and side clashes shown separately Resolve Conflicts places dynamic EQ cuts automatically Multiple simultaneous dynamic EQ nodes, each with depth, Q, attack, release and mid/side control Delta listening to hear exactly what is being removed Phase Analyze finds the best phase rotation between -180 and +180 degrees Volume balancing suggestions based on perceived loudness Works on a single track from its own signal, with no sidechain needed Zero latency Common Use Cases Kick vs. bass separation Vocal vs. lead synth or guitar separation Snare vs. guitar separation Pad vs. piano clarity Layered kicks and sub bass phase alignment FAQ What is FUSER? FUSER is a frequency masking plugin from Mastering The Mix. It finds where two tracks clash and turns down only those frequencies, only while they overlap. Is FUSER a sidechain compressor? No. FUSER applies sidechain-triggered dynamic EQ, which only ducks the clashing frequencies instead of turning the whole track down. Does FUSER work on the master bus? FUSER is designed for track-to-track unmasking. For work on the whole mix, MIXVAULT is the better fit.
